Mat lab audio files.

Write to audio file get information about audio file. Audio toolbox enables real time audio input and output. After you import or record audio matlab supports several ways to listen to the data. Sends the signal in vector y with sample frequency fs to the speaker on the pc and most.

For simple playback using a single function call use sound or soundsc. Sends the signal in vector y with sample frequency fs to the speaker on the pc and most unix platforms values in y are assumed to be in the range 1 0 y 1 0. On windows 7 platforms or later audioinfo might also return information about the contents of any files supported by windows media foundation.

Audio data in the file returned as an m by n matrix where m is the number of audio samples read and n is the number of audio channels in the file. On linux platforms audioinfo might also return information about the contents of any files supported by gstreamer. For example load a sample mat file that contains signal and sample rate data and listen to the audio.

Values outside that range are clipped stereo sound is played on platforms that support it when y is an n by 2 matrix. If you do not specify datatype or datatype is double then y is of type double and matrix elements are normalized values between 1 0 and 1 0.
