Can MATLAB 7.13 (R2011b) read and write to MP3 files?

Best Answer

This enhancement has been incorporated in Release 2012b (R2012b). For previous product releases, read below for any possible workarounds:

MATLAB 7.13 (R2011b) cannot currently read and write to MP3 files. Our development staff will look into adding this functionality in a future release of MATLAB.

Please consider converting your MP3 files into WAV (PCM format), which can be read into MATLAB.

MATLAB: Does the WAVREAD function from MATLAB 7.13 (R2011b) support ADPCM data format

This enhancement has been incorporated in Release 2012b (R2012b). For previous product releases, read below for possible workarounds:

WAVREAD does not support the ADPCM data format found in some WAV-files; it only supports the Microsoft PCM data format.

Possible workarounds are:

1. Convert your ADPCM files into PCM files using a converter program. There are some free and paid options available online.

2. The Simulink DSP System Blockset has a 'From Multimedia File' block that can read ADPCM WAV files. However, to utilize this, you must have Simulink and the DSP System Blockset licenses available, and then make a Simulink model that utilizes the block and outputs the data into the workspace.

MATLAB: Does MATLAB provide 24-bit audio support

This enhancement has been made for Release 14 (R14). For previous product releases, please read below for any possible workarounds:

Beginning with MATLAB 6.5 (R13), 24-bit audio is supported.

If you are using a previous version of MATLAB, only support -8 or 16-bit audio is supported. Please upgrade to the latest version of MATLAB if you are interested in the 24-bit audio support.

You can use the function AUDIOPLAYER in order to play a 24-bit sound recording. This function creates a handle to an audio player object. For details on this function, as well as a list of methods you can use on the audio player object, type:

doc audioplayer

Furthermore, you can also read and write 24-bit or 32-bit .wav files with the functions WAVREAD and WAVWRITE. Note, however, that the functions AUDIOPLAYER and AUDIORECORDER support 24-bit sound but not 32-bit.
