This application claims priority to Irish Patent Application No. S2013/0120 filed Apr. 9, 2013, the entire contents of which are hereby incorporated by reference as if fully set forth herein for all purposes.
The present invention relates to a system and method for generating an audio output file.
Digital audio workstations (DAWs) have been developed to provide users with a production environment in which an audio track may be composed, recorded, edited, mixed and then synchronised with target image or video content, including films, television shows, commercials, and/or gaming applications.
Such DAWs typically provide users with the required manipulation tools and a library of pre-recorded audio content which users select, edit and combine as desired to ensure that an audio track produced is aesthetically satisfactory and has the correct timings and length for seamless synchronisation with the target image and video content.
However, the selection of the appropriate pre-recorded audio content for creating an audio track for a film, a scene in a film, a television show, a commercial and/or a gaming application is extremely time consuming, even for the most skilled audio editors, since it is very unlikely that any single piece of pre-recorded audio content will have the appropriate timings and marry aesthetically with the image content with which it is to be synchronised. Moreover, the use and re-use of pre-recorded audio content in a DAW environment leaves open the possibility that audio content produced may not be sufficiently unique.
It is a therefore an object of the present invention to provide a system and method for generating an audio output file which goes at least some way toward overcoming the above problems and/or which will provide the public and/or industry with a useful alternative.
Further aspects of the present invention will become apparent form the ensuing description which is given by way of example only.
According to the invention, there is provided computer implemented method for generating an audio output file, the method including using one or more processors to perform steps of:
The present invention provides a method for generating an audio output file in a computer implemented development environment. The invention creates from pre-existing or pre-recorded audio tracks a library of audio content in the form of audio blocks. The stored audio blocks each correspond to an instrument, such as a piano, a drum, a synthesiser and the like, and are grouped for selection based on audio parameters of the audio tracks. The audio parameters comprise one or more of: tempo, genre and harmonic map, and define a music genre template map for an audio track.
The invention implements a tagging or indexing mechanism to associate with each audio block a unique identifier, and compares the unique identifiers for the selected audio blocks with records of other previous combinations of unique identifiers in a storage device to ensure that the combination is new so that a unique audio output file is generated.
Preferably, the step of using the unique identifiers to select audio blocks comprises: selecting a combination of audio blocks such that the unique identifiers for the combination of audio blocks selected is not located in a record of a storage device indicating that the combination is allowable.
Preferably, the step of using the unique identifiers to select audio blocks comprises: comparing the unique identifiers of the selected audio blocks with records in a storage device, such that if a record of a combination of the unique identifiers is located then an audio output file is not generated, and if a record of the combination of unique identifiers is not located then the selected audio blocks are combined to generate an audio output file.

In another embodiment of the invention, the method comprises the step of: storing the audio blocks in a storage device according to one of: the audio parameters of the audio block and musical instrument.
In this arrangement, audio blocks separated from audio tracks having the same audio parameters, and therefore have the same music genre template map, and which correspond to the same musical instrument, will be stored together, such as in a folder, of the storage device. Audio blocks separated from audio tracks having the same audio parameters, but which correspond to different musical instruments, will be stored separately in the storage device. Audio blocks separated from audio tracks having different audio parameters, and which correspond to different musical instruments, will also be stored in separately in the storage device.
In another embodiment of the invention, the method comprises the step of: selecting audio blocks for the audio output file according to user preference data including one or more of: music genre, music style and mood data.
Such music genre, music style and mood data defines user preference data which is provided as input by a user to user interface means via a menu, such as a drop down menu, an icon based menu or any other suitable means which provides users with the capability to view and select from a plurality of options regarding music genre, style and/or mood data or other user preference as required or as desired.
In another embodiment of the invention, the method comprises the step of: operating a hold module to retain one or more audio blocks selected by the audio block selection means and to interchange at least one of the audio blocks selected by the audio block selection means with a previously unselected audio block according to user preference data.

In another embodiment of the invention, the system comprises means for linking a plurality of storage devices to provide an extended storage library of audio tracks and audio output files for creating audio blocks.
In another embodiment of the invention, the system comprises:
In a still further embodiment of the invention, there is provided a non-transitory machine-readable medium including instructions that, when executed by one or more processors, cause the one or processors to perform the steps according to a method as described.
In yet another embodiment of the invention, there is provided a computing device and/or arrangement of computing devices having one or processors, memory and display means operable to display an interactive user interface having the features as described.
In another embodiment of the invention, there is provided a system for generating an audio output file substantially as herein described with reference to and as shown in the accompanying drawings and/or examples.
In another embodiment of the invention, there is provided a method for generating an audio output file substantially as herein described with reference to and as shown in the accompanying drawings and/or examples.
The invention will be more clearly understood from the following description of some embodiments thereof, given by way of example only, with reference to the accompanying drawings, in which:
Referring to the drawings, and initially to
The program instructions executable by the one or more processors provide means 4 for receiving audio tracks, in which each audio track is created according to audio parameters, such as tempo, genre and harmonic map. The audio parameters for the audio tracks define a music genre template map which may be distributed to individual human music composers who may author musical or other sound works based on the music genre template map, which form audio tracks for the system 1. Such audio tracks may be pre-recorded audio tracks, or be dynamically imported from an external source.
Also shown in
The system 1 further comprises means 14 for comparing the unique identifiers of the selected audio blocks with records in a storage device 9, and means 3 for generating an audio output file by combining the selected audio blocks if a record of the combination of unique identifiers is not located in the storage device 9. Also provided are means 50 for recording the combination of unique identifiers for audio blocks of the audio output file generated in the storage device 9.
Also shown in
The system 1 further comprises an audio mixing and editing module 53 which is operable to modify, refine, adjust, vary and/or change audio characteristics of the audio output file generated, the audio characteristics of a specific audio block in an audio output file, and also an audio track by adjusting the tempo and/or shifting the harmonic map of the audio track. Also shown, are means 54 for importing instrument performances and/or voice from an external source for incorporation into the audio output file.
An audio synchronisation module 55 is operable to synchronise the audio output file generated with a video file, a still image file, and/or a text file. Such synchronisation means 15 is further operable to enable users to mark events in a film or video clip with the use of a time line and to then deliver musical stingers relative to the key of the audio file generated.
For example, a user may prepare one or more audio files for use as musical stinger or swell and tag the audio file by a musical key, such as ‘A’ minor or any other key as desired. Then, when a film event needs audio content, for example, eighteen seconds into the film, a marker is created on the eighteen second point of the time line. The synchronisation means is then operable to analyze the harmonic map audio content of the film at eighteen seconds. Thus, for example, if the synchronization means detects that the audio content for the film is passing through the ‘A’ minor key at this point of the time line it retrieves from the library of audio files generated a stinger hit or swell relevant to the key of ‘A’ minor and places the stinger audio file at the eighteen seconds point of the time line. The audio file may be dragged along the film time line manually as required to make adjustments to its placement if necessary.
The storage means further comprises or is in the form of an audio storage library operable to store for retrieval the generated audio files as pre-recorded audio tracks. Audio editing means is operable to enable stored pre-recorded audio track to be edited by tempo adjustment and/or harmonic map shifting. The audio separating means is further operable for separating retrieved pre-recorded audio tracks into audio blocks which are made available for use in generating further audio files.
Such an arrangement provides back catalogs of audio files in the form of an interactive music content library. This is made possible by composers applying a musical template to existing musical tracks provided by previously generated audio files and adapting key influences to each part, stem, or instrument performance of that audio file. The key influences include adjusting of the tempo of the music and the moving of the harmonic mapping of the said audio file to the harmonic map dictated by the templates provided. Furthermore, linking music libraries enables content to be interactively adapted so that multiple new audio blocks may be generated by joining and pooling the interactive content of those libraries to create one mass universal pool of shared content.
Each audio output file generated is stored in the storage device 9 for retrieval as an audio track for the generation of additional audio output files. A plurality of storage devices 9 may be linked to provide an extended storage library of audio tracks and audio output files for creating audio blocks.
Once an audio output file has been generated, and/or a combined audio image multimedia file resulting from synchronisation of the audio output file with a video file, a still image file, and/or a text file, it is then able to be transmitted or downloaded to a user computing device 20 for subsequent editing and/or use. Such an audio output file and/or combined audio image multimedia file may be transmitted as a single complete file.
In an alternative transmission process an audio output file may be transmitted as file portions. To enable such a transmission process there is provided means 56 for separating the audio blocks of the audio output file into audio block segments, each audio block segment having a time slot such that audio block segments from the same audio block each have a different time slot, means 57 for transmitting audio block segments having same time slot together such that audio block segments having the same time slot are received at a computing device 20 at substantially the same time, and means 58 for combining at the computing device 20 audio block segments having the same time slot to form at least a portion of the audio output file and then combining the audio file portions to form the audio output file at the computing device 20.
Shown in
In the example shown, the music genre template map 6, identified as FANTASY GENRE MIDI FILE TEMPLATE MAP 4, has been sent to five composers 7. Each composer has produced a pre-recorded audio track 5, referred to as a 1st GENERATION MUSIC CUE, according to the audio parameters, which include, but are not limited to, tempo, genre and harmonic map, in the music genre template map 6. The various other music genre template maps 6, that is FANTASY GENRE MIDI FILE TEMPLATE MAPs 1 to 3, are also sent to the same or other composers or musicians for the composition of further audio tracks.
As shown in
The audio blocks 8 are stored in a storage means 9 of the system 1. The storage means 9 may be a local storage device, or a remote storage device, such as “cloud” based storage memory and access system.
The system 1 further comprises audio block tagging means 14 for assigning to each audio block 8 a unique identifier. For example, an audio block 8 derived from folder 9a and in the drums folder 10a may be assigned a unique identifier based on combinations of tags according to a template map identifier, the unique identifier based on the instrument part for the audio block, an identifier based on a number for the pre-recorded audio track, and an identifier for the composer or musician. Thus, for example, an audio block 8 in the drums folder 10a of
The system 1 further comprises an interactive user interface means 11 enabling users to interact with the system 1 via a computing device 20 to generate an audio output file. As shown in
As shown in
At step 27, a selection of audio blocks 8 from the folder 9a in the storage means 9 corresponding to the FANTASY 4 TEMPLATE is made by the audio block selection means 12, the selection being made according to the user preference data, such as music genre, style and/or mood data, received via the user interface means of the system 1. By selecting audio blocks 8 from the same folder 9a the audio block selection means selects audio blocks 5 with the same audio parameters for generating the audio file at step 28. In this way, the audio blocks 8 which are combined and used to create an audio file have the same tempo and harmonic map, which ensures the harmonic integrity of the audio file generated.
The unique identifiers of the selected audio blocks 8 are compared with records in a storage device of unique identifiers for previously generated audio output files, such that if a record of a combination of the unique identifiers is located then an audio output file is not generated, and if a record of the combination of unique identifiers is not located then the selected audio blocks are combined to generate an audio output file. In this way the system 1 prevents the use of the same combination of audio blocks in the generation of audio output to ensure that the audio output files generated a sufficiently unique.
The operation of the audio block selection means 12 will be shown by way of example and with reference to
In the instance shown in
As shown in
The audio block selection means 12 is also operable to interchange at least one selected audio block 8 with a previously unselected audio block 8 according to further user preference data received via the user interface means 11 of the system 1. The audio block selection means 12 comprises a hold function operable to enable a user to retain one or more audio blocks 8 selected by the audio block selection means 12. A shuffle function is also provided to enable a user to remove one or more audio blocks 8 selected by the audio block selection means 12, and select an alternative audio block 8 of the same audio parameters from the storage means 9. Thus if the user is unsatisfied with an audio file generated he or she simply asks for a regeneration. The system 1 shuffles the content within each instrument folder 10 within the associated single template map folder 9a and the audio block selection means 12 deals a new hand of audio blocks 8 forming another unique audio file. In addition the user may choose to hold certain performance audio blocks 8, such as piano or guitar and replace the remaining audio blocks 8 until a desired musical cue emerges from the collective single template map folder 9a.
In providing alternative audio block selection options to a user the system 1 is operable to ensure that the combination of audio blocks 8 in a resulting audio output file is unique by ensuring that the combination of unique identifiers for the audio blocks is not in a record of the storage device 9.
The system 1 further provides audio file recording means, editing means and mixing means enabling a user full creative control over mix and other parameters to modify as desired the audio file generated by the audio file generation means. Users may also import other instrument performances and/or voice from an external source and incorporate them into the audio file using the audio file recording means, editing means and mixing means, which are operable by the user interface means 11.
The system 1 is further operable to enable an audio output file generated to be made available for downloading to a computing device.
Audio segments p0 to pn, v0 to vn, and b0 to bn are then transmitted such that audio segments from different audio blocks having the same time slot are received at a receiving computing device 20 at substantially the same time. Thus, as shown in
At the receiving computing device 20 audio segments from the same time slot are then combined to form portions 40a to 40n of the audio file 40. The audio file portions 40a to 40n are then combined to reform the original audio file 40 at the computing device. Audio segments derived from the same time slot may also be shifted to a different time slot as desired.
The present invention thus also provides a protocol that interleaves audio segments specified by a common identifier provided as a time slot and enables them to be transmitted over a single data connection of undetermined bandwidth and latency such that they are received together at a client device for simultaneous interpretation or processing. Subsequent audio segments may be fetched over the same or other parallel data connections. The use of the time slot for each audio segment enables synchronicity for those audio segments.
The time slots for each audio block may be specified arbitrarily such that the sequence by which the audio segments are transmitted does not have to follow the sequence of audio segments in an audio block. Audio blocks may include a segment to act as marker for a specified time slot which allows for audio blocks to be of variable length. Other audio segments may be dynamically added or removed from an audio block. An audio segment may be marked as a terminal segment to indicate that it is the last audio segment in a transmission. This provides an option to terminate the download of an audio file.
The system 1 also provides audio mixing and editing functionality which allows new audio blocks 8 to be added after the editing of previous audio blocks 8 and entitles them to the same automatic editing. This ensures that all added audio blocks 8 will follow the harmonic integrity of the audio file generated. Also provided is a step back memory system, so that a user may return to an older arrangement if required. This is useful if a user decides he or she preferred an earlier audio file generated.
When user is fully satisfied with the audio output file generated they pay a license fee which grants a license under a publishing agreement with conditions. The final audio file is then downloaded to the users platform system in a format specified by the user.
The present invention provides a software application that may be plugged into a host program, such as UNITY or AVID, which are examples of programs typically used by game developers or film producers.
A music genre or category is selected by the user from a menu and an audio file offering is automatically generated. The audio file offering contains a number of audio blocks or stems of instrument performances and is then ready for audition in the game. Some or all audio block content may be replaced through a shuffle button system until the desired content starts to emerge. If, for example, the audio file is not suitable as an arrangement, but the piano audio block sounds ideal, then the user may hold the piano stem. The system Holds the piano stem and regenerates the remaining stems with alternative selections. This process can be repeated. The piano audio block will remain in place while all other audio block elements continue to change until an ideal arrangement of the chosen genre cue is achieved. The system allows for further editing possibilities such as fx and tools for a final mix.
When it is decided by the developer that the soundtrack works to the satisfaction of the game, film score, TV commercial or whatever application is intended then a licence fee and agreement is set out between the system and the developer. This is done on the fly within the system. When the license is paid, a stereo file of the music work is available for download to the developers system for final placement in the film, TV program or game. The final audio file is given a registered title by the user and the authors of that music work are deemed to be, the composers of the audio blocks combined in the audio file and the project developer or user, as they have been creatively involved in the arranged music work. Each audio block carries a unique identifier as a registration number and it is with these identifiers the software restricts this audio combination or anything close from ever recurring thus deeming the piece of music unique and original to that film or game project. The original audio blocks are returned to the collective for use in future unrelated arrangements.
The present invention integrates into mainstream professional game audio development platforms in a familiar and frictionless way, such as a plug-in to Unity3D, Final Cut Pro and the like.
The present invention includes wizard-like functions allow a user to quickly search and audition specially-curated audio collections in stem/audio block formats. Audio content is optionally delivered via a cloud-based library with a database of meta-data to facilitate intelligent search, shuffle etc. The present invention provides a range of edit/mix functions similar to those used in typical Digital Audio Workstations, allowing the user to easily tweak the production in familiar ways The present invention delivers a rendered audio file to the user and deliver relevant data to the cloud-based “audio accounting” back end to guarantee the audio file production's uniqueness.
The following describes a use case for the present invention. A user is doing some game visuals productions in his favorite production environment and wants to do some audio work. The user activates the present invention plug-in and makes initial wizard-driven creative choices based on desired theme, mood, genre etc. The present invention delivers a set of audio files into a DAW-style environment. The user auditions various audio block stems. Some work straight away and these are marked “Hold”. A shuffle is performed to get new audio and/or an “advanced search” to drill down deeply into the available content. With content choices made, the user previews the audio timeline and makes edits accordingly, with cut/paste, move/stretch actions. The user adjusts Mix levels, panning, sound effects and the like, using familiar actions.
