MATLAB: Doesn’t mp3write work in R2015b but it does in R2013b

MATLABmp3write

When I try to use mp3write in R2015b I get

Error using wavwrite (line 8) WAVWRITE will be removed in a future release. Use AUDIOWRITE instead.

Error in mp3write (line 53) wavwrite(Y,FS,NBITS,strcat(lame,'\temp.wav'));

I can always go back to R2013b because I luckily kept it but I would prefer to use the latest versions. Is there a mod available that will solve this problem? Thanks.

mp3write() is a File Exchange Contribution. Or maybe it is this other contribution. Either way it is not part of MATLAB.

You can adapt the source of whichever one you are using to use audiowrite() . It should be a minor change.

The warning comes from the standard MATLAB function wavwrite. Given some other questions on Answers, I think wavwrite may have changed its behavior recently (although I haven't checked). Basically, a vector that has a +1 value will be clipped (by a single quantization unit). My guess is that mp3write is scaling things to be +/-1 and that this causes the clipping warning.

You should report the warning on the fex page: http://www.mathworks.com/matlabcentral/fileexchange/13852-mp3read-and-mp3write

As a work around on line 53 (according to your error message) should be a line like

wavwrite(x, ...);

you can replace this with.

wavwrite(0.99*x, ...);

MATLAB: How to audiowrite a soundfile from m4a to wav

Laura - I think that you want to use audioread first as

 m4AFilename = 'hoi.m4a';
 [y,Fs] = audioread(m4AFilename);

and then write it as a wav file using audiowrite as

 wavFilename = 'hoi.wav';
 audio write(wavFilename,y,Fs);

Try the above and see what happens!
