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.

Leveling audio signals

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.

Systems and methods for adjusting audio attributes of clip-based audio content

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.

Method and apparatus for audio mixing

This specification describes technologies relating to generating audio mixes for listening environments. A method is provided that includes receiving digital audio data; receiving an environmental input, the environmental input being associated with the listening environment; calculating one or more audio parameters for the digital audio data based on the received environmental input, the calculating including: calculating a particular intensity level for the digital audio data, and processing the digital audio data according to specified reference levels; and generating an audio mix for the digital audio data according to the calculated audio parameters.

Audio mixes for listening environments

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. At least one audio clip of the first track is preprocessed to obtain characteristic data of the at least one audio clip of the first track. The characteristic data of the at least one audio clip is utilized to determine level change parameters for the at least one clip of the plurality of tracks linked to the first clip.

Method and apparatus for performing audio ducking

Technologies relating to user interfaces for visualization and editing of audio signals. In some implementations, a method is provided that include the actions of receiving one or more audio signals including digital audio data; generating one or more audio objects, each of the one or more audio objects representing one or more audio signals; and displaying a corresponding representation of each of the one or more audio objects in an interface according to one or more parameters of the audio signals associated with the respective one or more audio objects such that a location of each particular audio object representation in the interface is based on the one or more parameters associated with the particular audio object.

Representing and editing audio properties

Technologies relating to user interfaces for adjusting properties of audio signals and controls of an audio mixer. In one implementation, a method is provided that includes the actions of receiving one or more audio signals including digital audio data; generating one or more audio objects, each representing one or more audio signals; displaying an interface for representing properties of the audio signals including a region where each location within the region represents one or more audio properties relative to a virtual listener; displaying a corresponding representation of each of the one or more audio objects within the interface where the location of a particular audio object representation within the region corresponds to the one or more audio properties; adjusting the properties of the audio signals according to properties of the corresponding audio objects; and determining control parameters of an audio mixer according to properties of the audio signals.

Technologies relating to user interfaces for visualizing audio properties. In some implementations, a method is provided that includes the actions of receiving one or more audio signals including digital audio data; generating one or more audio objects, each of the one or more audio objects representing one or more audio signals; and displaying an interface for representing properties of the audio objects, the interface including a region where each location within the region represents two or more audio properties relative to a virtual listener.

Visualizing audio properties

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. Each of the parts further includes attributes indicative of the manner in which the part may be ordered, whether the part may be replicated or &#x201c;looped&#x201d; and modifiers affecting melody and harmony of the rendered finished composition piece.

Methods and apparatus for representing audio data

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.
