ConformAudio
ConformAudio[{audio1,audio2,…}]
returns a list of audio objects where all audioi are made to have conforming properties, including duration, data type, and number of channels.
ConformAudio[{audio1,audio2,…},spec]
returns all audio objects of the specified spec.
Details and Options

- ConformAudio is typically used as a preprocessing step to algorithms that need audio objects that are uniform in some way, such as classification, dimensionality reduction, and assembling into bigger audio objects.
- Audio specification spec can be one of the following:
-
audio take the conforming properties from audio duration duration given in seconds audiotype audio type as in AudioType {spec1,spec2,…} specification for multiple properties - By default, the smallest audiotype that can represent the data stored in all audioi is used.
- ConformAudio[{audio1,audio2,…}] pads all audio to the duration of the longest audioi.
- ConformAudio has the same options as Audio with the following additions and changes:
-
AudioOutputDevice Automatic default audio output device to use for playback SampleRate Automatic sampling rate Padding 0 padding method available in AudioPad - By default, SampleRate->Automatic takes the highest sample rate in all audioi.
