As shown in
With the widespread use of various sensors in multimedia equipment, particularly in mobile terminals, and the rapid development thereof, it is possible to receive a body movement of a user in real time. These control signals are converted into a manifestation mode desired by the user, and thus the original song may be changed. The changed song may be played in real time, that is, the user can listen to the song immediately. Alternatively, the user may store and share the changed song. Specifically:
processing an audio file by an analyzer or decoder to obtain original music signals, specifically: analyzing or decoding an audio file by an audio file analyzer or a decoder to obtain music signals associated with the original audio file;
acquiring corresponding control signals from the control of the user thus to obtain corresponding control parameters;
processing by a music style changer using other auxiliary files, for example, a lyric file, the music signals associated with the original audio file and the control parameters of the user, and then outputting music that has been changed in terms of interpretation style.
As shown in
S310: An audio file is analyzed to obtain a waveform audio file.
As shown in
The stored audio files include audio files of the compressed format, such as MP3, ACC, WMA, etc., and control audio files such as MIDI. For a compressed audio file, it is required to decompress the compressed audio file correspondingly to obtain a waveform audio file, while for a control audio file, for example, MIDI, it is required to perform analysis and synthesis to various control information therein.
The processing of input and output of an audio file analyzer or a decoder comprises the following steps of:
performing decompression, or, analysis and synthesis, to an audio file to generate a corresponding waveform audio file, specifically:
performing audio decompression or midi analysis and synthesis to a compressed audio file or midi file to generate a corresponding waveform audio file.
S320: Behavior information of a user is acquired and then converted into control parameter information.
As an embodiment of the present invention, the behavior information of a user comprises:
body movement information of a user, and/or humming information of a user.
Specifically, the body movement of the user results from the behavior of the user while listening to music, comprising: beating by swinging hands up and down, the force of swing representing the stress of the user; beating by tapping the feet, the force information characteristic of tapping the feet being not so obvious generally; some other body movements, for example, shaking the head, shrugging the shoulders, twisting the body.
As an embodiment of the present invention, acquiring behavior information of a user is performed by any one or more of the following equipment:
an acceleration sensor, a direction sensor, a three-axis gyroscope, a light sensor, an orientation sensor, a microphone, a camera and an ultrasonic gesture sensor.
To make an ordinary person skilled in the art understand the present invention better, the behavior information of a user acquired by the above various equipment will be briefly described hereinafter.
The acceleration sensor is electronic equipment capable of measuring acceleration. The acceleration refers to a force applied to an object when the object is accelerating. The acceleration may be a constant, for example g, or a variable. When a user hand-holds a terminal with an acceleration sensor embedded therein, or wears on the hand wearable equipment having an acceleration sensor, the swing of arms of the user may be detected, so that the force information and time information of the movement may be obtained. In addition, if a user wears the wearable equipment on the feet, the movement of tapping the feet may be detected.
As shown in
It can be seen from
The direction sensor, for example, a mobile phone direction sensor used in a mobile phone, may be applied in terminal equipment. Specifically, a mobile phone direction sensor is a component installed in a mobile phone to detect the directional state of the mobile phone itself. The mobile phone direction detection function may detect whether a mobile phone is held upright, upside down, leftward or rightward, or, faces up or faces down. A mobile phone having the direction detection function is more convenient and more humanized in use. For example, after the mobile phone is rotated, the picture on the screen may rotate automatically in a proper length-to-width proportion, and the text or menus may rotate simultaneously. Therefore, it is convenient for reading.
The three-axis gyroscope measures the positions, movement trajectories and accelerations in six directions simultaneously. With advantages of small size, light weight, simple structure and good reliability, the three-axis gyroscope has become a trend of the development of laser gyroscopes. The directions and positions measured by the three-axis gyroscope are stereoscopic. Particularly, in a case of playing large games, the advantage of stereoscopic directions and positions measured by the three-axis gyroscope is more prominent.
The light sensor, i.e., a photoreceptor, is a device capable of adjusting the brightness of a screen according to the brightness of ambient light. When in a bright place, a mobile phone will automatically turn off the keyboard light and slightly strengthen the brightness of the screen, resulting in saved power and better effects for looking at the screen. However, when in a dark place, the mobile phone will turn on the keyboard light automatically. Such a sensor mainly plays a role of saving the power of a mobile phone.
The orientation sensor is also known as an electronic compass or a digital compass which is a device for determining the North Pole by using the geomagnetic field. The orientation sensor is processed from a magnetoresistive sensor and a fluxgate. Such an electronic compass is able to bring more convenience for a user to use in coordination with a GPS and a map.
The microphone is a transducer for converting sound into electronic signals, as equipment for recording humming sound of a user. If a user listens to music with a pair of earphones, the microphone merely records the humming sound of the user; and, if the user listens to music with a loudspeaker, the microphone records both the humming sound of the user and the sound of the song from the loudspeaker.
As the camera, there are two kinds of cameras, i.e., digital cameras and analog cameras. An analog camera may convert analog video signals generated by video capturing equipment into digital signals and then store the digital signals into a computer. A digital camera may directly catch an image, and then transmit the image to the computer via a serial port, a parallel port or a USB interface. When a user stands in front of a terminal with a camera embedded therein, the camera may catch the gesture of the user.
The ultrasonic gesture sensor generates ultrasonic signals that can not be heard by human ears. When a person swings the hands before the equipment, the equipment can detect this movement based on the Doppler Effect.
This embodiment of the present invention merely lists the above equipment capable of acquiring the behavior information of a user. However, the equipment capable of acquiring the behavior information of a user is not limited thereto, and no detailed description will be repeated here.
As shown in
The processing of input and output of acquisition of user control information specifically comprises the following steps of:
acquiring and detecting the control information of a user to acquire the behavior information of the user, wherein the behavior information of a user comprises body movement information of a user, and/or humming information of a user. Specifically:
detecting the control information corresponding to the behavior of the user while listening to music by available equipment, outputting the time information of a corresponding movement, force information of the movement and humming sound, wherein: the behavior of the user while listening to music comprises swinging the hands, tapping the feet, shaking the head and humming; and the available equipment comprises an acceleration sensor, a camera, an ultrasonic gesture sensor and a microphone. However, the available equipment is not limited thereto, and no detailed description will be repeated here.
As an embodiment of the present invention, converting the behavior information into control parameter information comprises:
converting the body movement information of the user into beat information, and/or converting the body movement information of the user into audio information of a specific musical instrument, and/or converting the humming information of the user into user audio information.
Specifically, converting the body movement information of the user into beat information comprises:
detecting the movement of user's body by the acceleration sensor, and recording the periodical change of acceleration as beat information when detecting a periodical change of the acceleration. In the present invention, one period of the acceleration is defined as a process during which the acceleration turns to a positive value from zero, then turns to a negative value and finally turns to zero again within a predetermined time range; or, a process during which the acceleration turns to a positive value from zero, then turns to a positive value and finally turns to zero again within a predetermined time range. Usually, the predetermine time range is about the time length of one beat.
For example, one period of raising one hand for beating is specifically:
supposed that an upward direction, which is vertical to a horizontal plane, is defined as the positive direction,
at the start time t1 of raising one hand for beating, the initial speed is greater than 0, the acceleration is greater than zero, and the hand moves upward;
the initial speed is kept greater than zero while the acceleration turns to be less than zero, and the hand moves upward until the initial speed becomes zero, this moment is defined as the end time t2 of raising one hand for beating; and
the time from the start time t1 of raising one hand for beating to the end time t2 of raising one hand for beating is defined as one period.
One period of dropping one hand for beating is specifically:
an upward direction, which is vertical to a horizontal plane, is defined as the positive direction,
at the start time t3 of dropping one hand for beating, the initial speed is less than 0, the acceleration is greater than zero, and the hand moves downward;
the initial speed is kept less than zero while the acceleration turns to be less than zero, and the hand moves downward until the initial speed becomes zero, this moment is defined as the end time t4 of dropping one hand for beating; and
the time from the start time t3 of dropping one hand for beating to the end time t4 of dropping one hand for beating is defined as one period.
Specifically, as shown in
According to the habit of the beating gesture of a user, there may be two conditions:
as shown in
as shown in
Specifically, converting body movement information of the user into audio information of a specific musical instrument comprises:
catching body movement information of the user to obtain time information and force information of a corresponding body movement; and
controlling the specific musical instrument according to the time information and force information of the body movement to obtain the audio information of the specific musical instrument.
Specifically, as shown in
With respect to the demand that a user wants to add other music elements into an original song, for example, in this case, the equipment may play the role of a maraca. The sensor senses the swinging of the user, and then synthesizes the sound of the maraca by using the swinging rhythm and force as parameters.
The processing of adding in sound of a musical instrument specifically comprises the following steps of:
decoding an audio file by a player to acquire original music data;
acquiring control information from the control of a user, and then processing by a musical instrument sound synthesizer to obtain musical instrument sound data; and
inputting the original music data and the musical instrument sound data into a sound mixer for further processing. Specifically:
the equipment is stored with a sound library of various musical instruments;
a user selects a favorite musical instrument before use, for example, a maraca;
when the user has uploaded a piece of music, the audio file analyzer or decoder decodes the music in real time to obtain waveform audio data;
the control information of the user is acquired and the movement of the user is caught in real time to obtain time and force information of the movement;
the musical instrument sound synthesizer is controlled according to the time and force information of the movement to obtain the sound of the corresponding musical instrument; and
the sound mixer mixes the original waveform audio data with the musical instrument sound data.
Specifically, converting the humming information of the user into user audio information comprises:
receiving external sound information by the microphone, and performing signal processing to the external sound information to obtain the user audio information.
Specifically, as shown in
With respect to the demand that a user wants to add his/her own sound into the original sound, for example, in a case that the user sings along with the song while listening, the equipment mixes the sound of the user into the original song. The user may store or share the processed song over the internet.
The processing of chorusing by a user and a singer specifically comprises the following steps of:
inputting an audio file to an analyzer or a decoder to be processed, in order to generate an original music signals;
acquiring a control signal by the user's humming, performing signal separation and noise reduction to the signal if the user listens to the music with a loudspeaker, and matching in terms of syllables and then mixing the humming signal and the original music signal; and
performing noise reduction to the signal if the user listens to the music with a pair of earphones, and matching in terms of syllables and then mixing the humming signal and the original music signal. Specifically:
after a user has uploaded a piece of music, an audio file analyzer or a decoder decodes the music in real time to obtain waveform audio data and plays the waveform audio data; meanwhile, an MIC records an audio humming signal of the user.
If the user listens to the music with a loudspeaker, the signal recoded by the MIC is mixed up with the original song and the background noise, so it is required to remove the original song and the background noise; in this case, it is required to use the original signal data as an auxiliary signal for purpose of processing, and the processed signal comprises the humming signal of the user only; and then, matching in terms of syllable and sound mixing are performed to the humming signal and the original song.
If the user listens to the music with a pair of earphones, there may be background noise in the signal recorded by the MIC, so it is required to remove the background noise, and the processed signal comprises the humming signal of the user only; and then, matching in terms of syllable and sound mixing are performed to the humming signal and the original song.
S330: The waveform audio file is processed according to the control parameter information and then music that has been changed in terms of interpretation style is output.
As an embodiment of the present invention, processing the waveform audio file according to the control parameter information and outputting music that has been changed in terms of interpretation style comprise any one or more of the following ways:
stressing and then outputting syllables in the waveform audio file according to the beat information.
Specifically, as shown in
A same song may be interpreted by different tones.
It can be seen from
Specifically, as shown in
Changing a song by stressing syllables specifically comprises the following steps of:
decoding a compressed audio file to obtain the decompressed audio, identifying syllables in coordination with a lyric file to obtain the time slice of each syllable, further identifying the fundamental tone to obtain the fundamental tone information, and then calculating the position of harmonics to obtain the harmonics information;
detecting swinging of the user by an acceleration sensor to obtain the force information and time information of a movement, calculating and processing gains thereof;
meanwhile, performing time matching to the time information of a movement and the time slice of each syllable to obtain syllables to be stressed;
stressing the fundamental tone and harmonics of the syllables, in coordination with the syllables to be stressed in tone, the fundamental tone information, the harmonics information and the gain information, further performing energy control to the processed syllables in order to avoid overflow and make smooth energy, and finally obtaining syllables stressed in tone; and
performing seamless transition, i.e., performing seamless transition to the decompressed audio which has been not yet processed and the audio which has been already processed in tone to obtain a song stressed in tone. Specifically:
a) after a user has uploaded a piece of music, a waveform audio file is obtained by an audio file analyzer or a decoder;
b) the system automatically identifies the time slice of each syllable (or each word) in the lyric, in this case, the lyric information may be used as auxiliary information for identification, and information about the time slice of each syllable is recoded, for example,
“We”: [t11, t12]
“are”: [t13, t14]
“all”: [t15, t16]
here, it is unnecessary to identify words “We”, “are” and “all”, as long as the voice or voice with background music is identified;
c) the system automatically calculates the fundamental frequency of each syllable (or each word), calculates the frequency position of harmonics of the fundamental frequency, and records it down;
d) when the user swings the mobile phone, the force of the movement is caught by the acceleration sensor, and the time of the movement is recorded;
e) the system matches the time obtained in d) with the time obtained in b), that is, determines into which time period of b) the d) falls, to obtain the time slice of each syllable to be stressed;
f) the syllable segment obtained in e) is transformed to a frequency domain;
g) a gain controller of the frequency domain is obtained by using the fundamental frequency and position of harmonics calculated in c);
h) the gain value of the gain controller depends upon the force parameter obtained in d), that is, the larger the force is, the larger the gain is;
i) the gain controller is applied to step f);
j) then, the syllable segment is inversely transformed to a time domain;
k) energy smoothing is performed to the processed and stressed syllables (or, performed after step i), and energy smoothing and anti-overflow processing are performed in the frequency domain; and
l) the processed syllables are spliced with the audio that has not yet been processed in the time domain.
The audio information of the specific musical instrument is mixed with the waveform audio file and then output.
The user audio information and the waveform audio file are matched in terms of syllables, superimposed and output.
As an embodiment of the present invention, outputting music that has been changed in terms of interpretation style comprises:
outputting the music that has been changed in terms of interpretation style in real time or in non-real time.
Specifically, outputting the music that has been changed in terms of interpretation style in real time after stressing syllables in the waveform audio file according to the beat information comprises:
stressing syllables in the waveform audio file when detecting a periodical change of the acceleration; and
stressing syllables in the waveform audio file and then outputting when detecting a next periodical change of the acceleration within a predetermined time.
Specifically, both changes, i.e., stressing syllables and adding a musical instrument, may realize output in real time, that is, a user controls while listening to music. The final signal heard by the user comprises the original song and the control expressions simultaneously.
After catching the movement of the user and processing the song, the timing of playing in real time is as follows. Given that the habitual beating gesture of the user is: a hand rises at the moment before the stressed syllables and then drops. As shown in the following figure, “We” and “fa” are stressed; and, according to the habitual gesture, a hand rises before these syllables and drops at these syllables. Raising a hand and dropping a hand actually appear in pair. Further, the speed and amplitude of raising a hand can reflect the strength of stressing. The timing problem may be solved by catching the movement of raising a hand.
As shown in
Various processing by a music style changer may realize output in non-real time, that is, a user may store the changed music into a local disk or share it over the internet.
Wherein, as there is no real-time requirement for syllable stressing, the equipment may stress syllables after acquiring accurate control information of the user. Specifically:
the process of storing or sharing the processed song in non-real time specifically comprises the following steps of:
decoding a music file by a player to obtain a music signal;
obtaining sensing control information of a sensor by the control of a user and outputting a corresponding movement acceleration and time; and
stressing syllables in combination with the music signal as well as the movement acceleration and time, compressing and decoding the processed result, and finally storing or sharing. Specifically:
pre-processing a song to obtain the syllables, the fundamental tone and the harmonics corresponding to the syllables;
catching a movement of the user by an acceleration sensor, and recording acceleration and time information of the movement of the user only differencing from the timing requirement in the real-time processing, to obtain [gz(t21), gz(t22), . . . , gz(t2n)];
processing all syllables to be stressed, and then splicing the syllables together;
compressing and coding the processed song;
storing the song in a local disk or sharing it over the internet.
In the embodiments as provided by the present invention, by analyzing an audio file to obtain a waveform audio file; acquiring behavior information of a user, and converting the behavior information into control parameter information; and, processing the waveform audio file according to the control parameter information and outputting the music that has been changed in terms of interpretation style, a user may change the interpretation style of music according to the current emotional needs, so that the diverse demands of the user are satisfied, and the user experience is improved. The above solutions as provided by the present invention just make minor modification to the existing systems, and hence will not influence the system compatibility. Moreover, the implementations are both simple and highly effective.
Further, when a user swings a mobile phone while listening to music, the mobile phone can let the user listen to different interpretation styles of the singer according to the force of swinging. Therefore, the user does not listen to music passively any more, and may change the music according to the current emotional needs and thus enjoy own music world. Meanwhile, the user may store the music conforming to the current emotion or share it over the internet.
Further, outputting a waveform audio file in real time solves the time delay in the prior art, so that the user can better interactively share the music that has been changed in terms of interpretation style with friends in real time, and the user experience is thus improved.
