Basic Examples  (2)

Reverse an audio recording:

Wolfram Language code: a = ExampleData[{"Audio", "MaleVoice"}, "Audio"];
Wolfram Language code: AudioReverse[a]

Process the audio track of a video:

Wolfram Language code: AudioReverse[\!\(\*VideoBox["![Video Player: ExampleData/fish.mp4](video://content-2sfji)"]\)]

Applications  (2)

Reverse an audio recording to hide a message, also known as backmasking:

Wolfram Language code: AudioReverse[SpeechSynthesize["This is a reversed audio."]]

Reverse a backmasked audio to reveal the hidden message:

Wolfram Language code: AudioReverse[\!\(\*AudioBox["![Embedded Audio Player](audio://content-gdi02)"]\)]

Properties & Relations  (1)

AudioReverse reverses the data in every channel separately:

Wolfram Language code: a = ExampleData[{"Audio", "Bee"}];
Wolfram Language code: AudioChannels[a]
Wolfram Language code: AudioPlot[{a, AudioReverse[a]}]
Wolfram Language code: AudioData[AudioReverse[a]] == Reverse[AudioData[a], 2]
