Abstract: The present specification relates to systems, methods, and apparatus including computer program products for editing digital audio data. In some implementations, a method is provided that includes the actions of receiving digital audio data; dividing the audio data into first audio data and second audio data; performing on-line processing of the first and second audio data including segmenting the first audio data according to one or more partitioning parameters into discrete time partitions, sequentially analyzing for each discrete time partition the first audio data of the corresponding discrete time partition, and modifying the second audio data according to the analysis of the first audio data; and outputting the modified second audio data.

Abstract: Systems and methods are disclosed to adjust the loudness or another audio attribute for one or more audio clips. Intra-track audio levels can automatically be equalized, for example, to achieve a homogeneous audio level for all clips within an audio track. Information about such audio adjustments may be identified and stored as information without destructively altering the underlying clip content. For example, keyframes may define changes to a fader that will be applied at different points along a track's timeline to achieve the audio adjustments when the track is played. An audio editing application can provide a feature for automatically determining appropriate keyframes, allow manual editing of keyframes, and use keyframes to display control curves that represent graphically the time-based adjustments made to track-specific faders, play test audio output, and output combined audio, among other things.

Abstract: A method, apparatus and computer program product for mixing audio is presented. A plurality of tracks is displayed in a user interface, each track of the plurality of tracks including at least one audio clip. Each audio clip is designated as either a foreground clip or a background clip. The foreground clips are analyzed and loudness corrected. The background clips are analyzed and a distance value between the loudness corrected foreground clips and the background clips is defined. Keyframes are added to some of the audio clips, the keyframes providing a fade between levels of the background clips to take into account the loudness corrected foreground clips and a sequenced audio file is produced from the corrected foreground clips, the background clips and the keyframes.

Abstract: A method, apparatus and computer program product for performing audio ducking is presented. A plurality of tracks are displayed in a user interface, each track of the plurality of tracks including at least one audio clip. A first clip of the plurality of tracks is linked to at least one other clip of the plurality of tracks.

Abstract: An audio storage architecture allows an audio management application to manipulate and recombine segments of a musical piece such that the resulting finished composition includes parts (segments) from the decomposed piece, typically a song, adjustable for length by selectively replicating particular parts and combining with other parts such that the finished composition provides a similar audio experience in the predetermined duration. The architecture defines the parts with part variations of independent length, identified as performing a function of starting, middle, (looping) or ending parts. Each of the parts provides a musical segment that is integratable with other parts in a seamless manner that avoids audible artifacts (e.g. “pops” and “crackles”) common with conventional mechanical switching and mixing.

Abstract: An audio formatting process identifies a musical score of audio information operable to be rendered by a rendering application. The audio formatting process enumerates aspects of the score such that the aspects are operable to define renderable features of the score. The aspects further define a duration modifiable by the rendering application to a predetermined duration that preserves the tempo of the score. Additionally, the audio formatting process stores the enumerated aspects according to a predetermined syntax operable to indicate to the rendering application the manner of accessing each of the aspects of the score.
