Various other objects, features and many of the attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description of the preferred embodiment when considered in connection with the accompanying drawings, in which:
A best mode for embodying the present invention will be explained hereinafter with reference to drawings.
The storage portion 100 in
The setting portion 110 in
When the musical instrument identifier is selected or the reference pitch is inputted, the setting portion 110 sets to each portion of the tuner apparatus 10 the transposition parameter, score parameter, pitch detecting parameter and reference pitch, those being stored in the storage portion 100 as associated with the musical instrument Identifier. Specifically, the setting portion 110 sets the pitch detecting parameter read from the storage portion 100 to the pitch detecting portion 130 as well as the transposition parameter and score parameter read from the storage portion 100 to the display control portion 160. Further, the setting portion 110 sets the reference pitch data indicating the reference pitch inputted via the GUI screen to the target note specifying portion 140 and calculating portion 150. As described above, the setting portion 110 functions as user interface providing portion that provides a user interface for utilizing the tuner apparatus 10 and read-out portion for reading out from the storage portion 100 various parameters according to the type of the musical instrument inputted via the user interface.
The input portion 120 is, for example, an input terminal, and is connected to the microphone 20. When a tone signal of a performed note collected by the microphone 20 is supplied from the microphone 20, the input portion 120 delivers this tone signal to the pitch detecting portion 130.
The pitch detecting portion 130 performs a pitch detecting process in accordance with a predetermined pitch detecting algorism to the tone signal delivered from the input portion 120, thereby detecting a pitch of the tone signal (i.e., a pitch of the performed note). Thereafter, the pitch detecting portion 130 delivers data (hereinafter referred to as “pitch data”) indicating this pitch to the target note specifying portion 140 and calculating portion 150. The configuration of the pitch detecting portion 130 will be explained hereinafter with reference to
The buffer input section 131 samples the tone signal delivered from the input portion 120 at a constant sampling interval (hereinafter referred to as “buffer length”), and then, delivers this sampling result to the pitch detection preprocessing section 132, amplitude envelope detecting section 133 and breath noise detection preprocessing section 134. The buffer length is included in the above-mentioned pitch detecting parameter and is set to the buffer input section 131 by the setting portion 110. In this embodiment, a value of n cycle (n is a lowest periodicity that can detect a pitch) of the lowest pitch that can be performed by the musical instrument to be tuned is set as this buffer length.
The pitch detection preprocessing section 132 in
The amplitude envelope detecting section 133 in
The breath noise detection preprocessing section 134 in
The pitch presence determining section 136 in
In case where the control signal indicating that a pitch is present is supplied from the pitch presence determining section 136, the pitch detecting section 137 in
As described above, the storage portion 100 stores a pitch detecting parameter preferable for performing the pitch detection to the musical instrument for every type of each musical instrument in this embodiment. In the tuner apparatus 10, the pitch detecting parameter corresponding to the type of the musical instrument selected by a user as a musical instrument to be tuned is set to each section of the pitch detecting portion 130, so that the pitch detection can be performed in a preferable manner according to the type of the musical instrument to be tuned. Therefore, the pitch of the performed note can be detected with high precision. When the pitch detection is performed by the pitch detecting portion 130, the pitch data indicating this pitch is delivered to the target note specifying portion 140 and calculating portion 150.
Returning again to
The calculating portion 150 calculates a difference between the pitch of the target note specified by the target note specifying portion 140 and the pitch detected by the pitch detecting portion 130, and delivers data (hereinafter referred to as “pitch difference data”) indicating this difference to the display control portion 160. More specifically explained, the calculating portion 150 calculates a cent value of the pitch indicated by the pitch data, supposing that the pitch of the note having the note name indicated by the target note data delivered from the target note specifying portion 140 is 0 cent, and delivers the data indicating this cent value to the display control portion 160 as the pitch difference data. In case where the target note data is the data indicating the pitch of the target note, the difference between the pitch indicated by the target note data and the pitch indicated by the pitch data may directly be obtained.
The display control portion 160 controls the display device 30 so as to display the pitch difference between the performed note and the target note, the note name of the target note and octave position. More specifically, the display control portion 160 controls the content of the display of the display device 30 by supplying later-described three types of control signals to the display device 30. The first control signal supplied to the display device 30 from the display control portion 160 is the one for instructing that the value indicated by the pitch difference data delivered from the calculating portion 150 is displayed on an area 250 in
Subsequently explained with reference to the drawings is an operation, among operations performed by the tuner apparatus 10, that remarkably represents the feature of the invention. The following example of the operation explained hereinafter is made about the case where a musical instrument that is to be tuned is a bass clarinet. In the example of the operation explained hereinafter, the transposition parameter stored in the storage portion 100 as associated with a musical instrument identifier indicating a bass clarinet includes a first parameter indicating that a key of the bass clarinet is “in Bb” and a second parameter indicating that its octave shift is “+1”. Further, the clef indicated by the score parameter stored in the storage portion 100 as associated with the musical instrument identifier is “G clef”.
[Parameter Setting Operation]
Firstly explained with reference to
When the above-mentioned operation is performed, the setting portion 110 obtains the reference pitch data indicating the reference pitch via the GUI screen shown in
Subsequently, the setting portion 110 delivers various parameters obtained at the Step SA1 to each portion of the tuner apparatus 10, thereby setting these parameters (Step SA2). Specifically, the setting portion 110 sets the reference pitch data obtained at the Step SA1 to the target note specifying portion 140 and calculating portion 150, and sets the pitch detecting parameter obtained at the Step SA1 to the pitch detecting portion 130. Further, the setting portion 110 sets the transposition parameter and the score parameter obtained at the Step SA1 to the display control portion 160.
The display control portion 160 having set thereto the transposition parameter and the score parameter controls the display device 30 so as to display the content according to these parameters onto the GUI screen (Step SA3). Specifically, the display control portion 160 supplies to the display device 30 a control signal for instructing that a key (i.e., “in Bb”) indicated by the transposition parameter is displayed onto the area 210 in
[Tuning Aid Operation]
Subsequently, the tuner apparatus 10 calculates, by the calculating portion 150, a pitch difference between the target note specified at the Step SB3 and the pitch of the performed note (Step SB4). Then, the tuner apparatus 10 causes, by the display control portion 160, the display device 30 to display the pitch difference calculated at the calculating portion 150, a note name of the target note specified by the target note specifying portion 140 and a note indicating the octave position of the target note (Step SB5). Specifically, the display control portion 160 supplies to the display device 30 a control signal instructing that a pointer of the virtual meter displayed in the area 250 in
As a result, the display device 30 displays the GUI screen shown in
On the other hand, the tuner apparatus 10 according to this embodiment displays the note name of the performed note and its octave position by using a transposition according to a type of a musical instrument that is to be tuned and a score that is usually utilized for this musical instrument as shown in
Subsequently, a tuner apparatus 40 according to a second embodiment of the present invention will be explained.
In case where the difference between the pitch of the performed note detected by the pitch detecting portion 130 and the pitch of the target note is a value within a predetermined range (for example, −5 cent to +5 cents), the determining portion 170 operates the display control portion 160 to cause the display device 30 to display the difference between both pitches, the note name of the target note and octave position of the target note. This embodiment explains about the case wherein predetermined target note data is stored beforehand in the storage portion 100, but a user may input the target note data to designate the target note. Specifically, an area to which the target note data is inputted by a user is newly provided on the GUI screen shown in
Subsequently explained is an operation, among operations performed by the tuner apparatus 40, that remarkably represents the feature of the invention. The following example of the operation explained hereinafter is made about the case where a character string “C3” is stored beforehand as the target note data in the storage portion 100. Further, the following example of the operation explained hereinafter is made about the case wherein a bass clarinet is tuned, like the first embodiment. The parameter setting operation is the same as that performed by the tuner apparatus 10, so that its detailed explanation is omitted.
Therefore, only when the difference between the pitch of the performed note and the pitch of the target note designated beforehand is within a predetermined range (for example, −5 cent to +5 cents), the area 250 on the GUI screen shown in
As described above, the tuner apparatus 40 according to this embodiment can smoothly perform the tuning aid operation without causing useless confusion to the user. In addition, a tuning operation can be performed as a note to be tuned is designated, if a user is caused to designate a target note.
Subsequently, a tuner apparatus 50 according to the third embodiment of the present invention will be explained.
The interval relationship specifying portion 180 specifies an interval relationship between the target note specified by the target note specifying portion 140 and the note indicated by the root data. In case where the interval relationship specified by the interval relationship specifying portion 180 is a predetermined interval relationship (for example, harmonics such as minor third, major third, perfect fourth or perfect fifth), the calculating portion 150 and display control portion 190 are driven in the tuner apparatus 50. The following explanation is made about the case wherein the data indicating the predetermined interval relationship is stored beforehand in the storage portion 100, but a user may set the data to set the predetermined interval relationship. In this case wherein the interval relationship is set by the user, the target note specification portion 140 and/or the interval specification portion 180 drive the calculating portion 150 and display control portion 190 based on the root, the standard pitch set by the user and the interval relationship set by the user. In other words, a note, which has the interval relationship set by the user with the root in the predetermined temperament, is specified by the target note specification portion 140 and/or the interval specification portion 180 based on the root, the standard pitch and the interval relationship. Further, this embodiment explains about the case wherein the calculating portion 150 and the display control portion 190 are driven only in case where the predetermined interval relationship is established between the root and the target note. However, the calculating portion 150 and the display control portion 190 may be driven, regardless of whether the predetermined interval relationship is established between the root and the target note.
The display control portion 190 in
The first control signal supplied to the display device 30 by the display control portion 190 is a control signal for instructing that, on the virtual meter displayed on the area 250 in
The second control signal supplied to the display device 30 from the display control portion 190 is a control signal instructing that the character string indicating the interval relationship specified by the interval relationship specifying portion 180 is displayed on the area 270 in
Since the tuner apparatus 50 according to this embodiment has the configuration explained above, a user can perform tuning the note (i.e., the note in predetermined harmony with the root), that has a predetermined interval relationship with the root indicated by the root data, defined as the target note. If the tuner apparatus 50 is provided with a sound output portion for outputting the root tone, it becomes possible to practice playing a musical instrument as audibly grasping the interval relationship with this root, i.e., to practice playing harmony. The present embodiment explains about the case wherein, in case where there is a predetermined interval relationship between the root and the target note, the pitch position is informed by displaying the predetermined mark at the pitch position of the target note. However, the pitch position may be informed by lighting an indicator arranged beforehand at the pitch position. Further, as shown in
Subsequently explained with reference to the drawings is an operation, among operations performed by the tuner apparatus 50, which remarkably represents the feature of the invention. The following example of the operation explained hereinafter is made about the case where a flute is used in practicing playing harmony. In the example of the operation explained hereinafter, the transposition parameter stored in the storage portion 100 as associated with a musical instrument identifier indicating a flute indicates that a key of flute is “in C “and its octave shift is “0”. Further, the clef indicated by the score parameter stored in the storage portion 100 as associated with the musical instrument identifier is “G clef”. Further, the storage portion 100 stores data indicating that the note name of the actual tone pitch is “C4” as the root data.
The flow of the parameter setting operation performed by the tuner apparatus 50 is the same as that performed by the tuner apparatus 10, except that the values of the transposition parameter and score parameter are different, so that the detailed explanation is omitted. A harmony lesson aid operation performed by the tuner apparatus 50 will be explained hereinafter.
For example, in case where the performed note is “E4”, this performed note has the interval relation of “major third” (the interval relationship wherein, supposing that the pitch of the latter is 0 cent, the pitch of the former is −13.7 cent: sometimes referred to as “Major 3rd”) with the root (“C4”), so that the GUI screen shown in
As described above, only in case where the target note has the predetermined interval relation with the predetermined root, the pitch difference between the performed note and the target note is displayed with the use of a meter, and the character string indicating the aforesaid interval relationship, the pitch position of the equal temperament interval corresponding to the target note and the note name and octave position of both notes written in a score are displayed, according to the tuner apparatus 50 of this embodiment. This allows the user to visually grasp the pitch difference between the performed note and the target note and to visually grasp the harmonic relation between the performed note and the root. As described above, all pitch positions of the notes that are in harmonic relation with the predetermined root are displayed in the conventional tuner apparatus for practicing playing harmony, so that the display content is complicated (see
Each embodiment of the present invention has been explained above. However, the modifications explained below may be added thereto.
The above-mentioned each embodiment explains about the case in which the transposition parameter indicating the key or octave shift of this musical instrument is set by selecting the musical instrument identifier indicating a musical instrument to be tuned by a pull-down menu. This provides an effect that the transposition parameter suitable for each musical instrument can conveniently be set. However, the parameter may be independently inputted by a user. Alternately, a rewriting portion may be provided for rewriting each parameter set by a pull-down menu according to a demand of a user. Further, holding portion (e.g., Random Access Memory or the like) for holding the transposition parameter read from the storage portion 100 according to the type of the musical instrument selected by a user may be provided, wherein, in case where a user performs a predetermined operation, the transposition parameter rewritten by the user may be again rewritten with the transposition parameter held at the holding portion for every parameter, such as the parameter indicating the key or the parameter indicating the octave shift. This provides an effect that the transposition parameter can flexibly be set according to a demand of a user.
The above-mentioned each embodiment explains about the case in which the musical instrument identifier indicating a musical instrument to be tuned is selected by appropriately operating a pull-down menu by a user. However, the musical instrument to be tuned may be automatically recognized based upon the performed note of the musical instrument to be tuned, for example. Specifically, the musical instrument identifier and the parameter indicating a feature in the waveform of the performed note of the musical instrument indicated by the musical instrument identifier are stored in the storage portion 100 as associated with each other. Then, the waveform of the performed note inputted to the input portion 120 is analyzed to extract its feature, whereby the musical instrument playing this performed note may be recognized based upon the extracted feature and the storage content in the storage portion 100.
The above-mentioned each embodiment explains about the case in which the pitch detecting parameter preferable for each musical instrument, transposition parameter indicating the transposition of each musical instrument and score parameter indicating a score preferable for the musical instrument are stored in the storage portion 100 as associated with the musical instrument identifier indicating a type of the musical instrument. However, in addition to the pitch detecting parameter, transposition parameter and score parameter, a meter displaying parameter for specifying the display manner upon displaying the pitch difference between the target note and the performed note with the use of a meter may be stored in the storage portion 100 as associated with the musical instrument identifier. Examples of the meter display parameter include the detection interval of pitches in the pitch detecting portion 130, data for specifying that no-pitch is displayed on the meter display upon how many times the determination that there is no pitch are continuously made in the pitch presence determining portion 136, whether the history of the pitch detected by the pitch detecting portion 130 is averaged to be displayed on the meter, a method of averaging and a number of history utilized for averaging, whether an interpolation is performed or not so as to smoothly display the change in the pointer position upon renewing the display of the virtual meter or dividing number of the interpolation, or the like. For example, the period of the performed note is long in a bass instrument, so that the detection frequency of a pitch is decreased. Therefore, there is a fear that the change in the pointer position is discontinuous. As for such a bass instrument, the dividing number is increased to be associated with the meter display parameter indicating that the interpolation is performed, whereby the change in the pointer position of the virtual meter can be made smooth.
The above-mentioned first and second embodiments explain about the case wherein the note name of the target note that is positioned nearest to the performed note in a predetermined temperament is converted into the note name written in a score and the resultant is displayed. However, a user may decide whether the conversion is performed or not. If there is a setting that the conversion is not performed, the note name of the target note in the actual tone pitch may be displayed. Further, a user may set whether the transposition is performed or not for the display position of the note corresponding to the target note, and this note may be displayed according to the setting content. This provides an effect that the display manner can flexibly be changed according to a demand of a user, such as the note name of the target note is displayed as a note name in the actual tone pitch, while the position of the note on the staff in the area 260 in
The aforesaid each embodiment explains about the case wherein the score parameter indicating a clef written in the staff displayed on the area is written in the storage portion 100 as associated with the musical instrument Identifier. This makes it possible to display the staff in which the clef suitable for the range of the musical instrument to be tuned is written. However, a staff in which a G clef is always written as a clef may be displayed, or a staff in which an F clef is always written as a clef may be displayed. Specifically, a staff in which a fixed clef is always written may be displayed, not depending upon a type of a musical instrument.
The above-mentioned each embodiment explains about the case wherein the pitch difference between the performed note played by the musical instrument to be tuned and the target note is converted into a cent value and the resultant is displayed on the virtual meter. However, the pitch of the performed note and the pitch of the target note may be displayed by a bar graph. Alternately, both pitches and its pitch difference may be displayed by a numeric value. Any one of the display manners may be adopted, so long as they understandably display the pitch difference between the performed note and the target note.
The above-mentioned each embodiment explains about the case wherein the tuner apparatus according to each embodiment is composed of each portion that realizes a function intrinsic to the tuner apparatus according to the present invention. However, a software that causes a control portion such as a CPU (Central Processing Unit) to function as each portion is installed in a computer apparatus, wherein the control portion is operated in accordance with the software to give the computer apparatus the same functions as those of the tuner apparatus according to the above-mentioned embodiments. For example, the software is recorded on a computer-readable recording medium such as a CD-ROM (Compact Disk Read Only Memory) or the like and this recording media is distributed, or the software is distributed via an electrical communication line such as the internet. This provides an effect that the software is installed into an ordinary computer apparatus for making this computer function as the tuner apparatus according to the present invention.
