AudioChannelCombine
AudioChannelCombine[{audio1,audio2,…}]
creates a multichannel audio object by combining the sequence of channels in audioi.
Details and Options
- AudioChannelCombine is typically used to create a multichannel audio object by combining channels from multiple audio inputs.
- All audioi are conformed to have the same type, sample rate, and duration before being combined.

Combine two audio signals into one:
a = ExampleData[{"Audio", "DogBark"}, "Audio"];
b = ExampleData[{"Audio", "Cat"}, "Audio"];AudioChannels /@ {a, b}AudioChannelCombine[{a, b}]The result has all four channels combined:

Combine two single-channel, single-tone signals into one:
AudioChannelCombine[{AudioGenerator[{"Sin", 852}], AudioGenerator[{"Sin", 1477}]}]Combine two audio signals with different properties:
step = ExampleData[{"Audio", "Apollo11SmallStep"}, "Audio"];
wind = ExampleData[{"Audio", "Wind"}, "Audio"];
combined = AudioChannelCombine[{step, wind}]Compare properties before and after:

AudioChannelCombine does the inverse operation of AudioChannelSeparate:
a = ExampleData[{"Sound", "Piano"}, "Audio"]AudioChannelCombine[AudioChannelSeparate[a]]a === %Text
