how to convert a .mp3 to .wav file in matlab?

i need to know about how to convert a single .mp3 audio file to a single .wav file in matlab? what code i have to use?

i had using this code:

filename=audioread('C:\Users\Rini Indrayani\Documents\MATLAB\Matlab\asli4.mp3');
audiowrite(filename,'C:\Users\Rini Indrayani\Documents\MATLAB\Matlab\hasilwav4.wav');

but the matlab shows error:

Error using audiowrite (line 100)
Not enough input arguments.

what should i do? i am a newbie in matlab. need a help. thanks

mp3filename = 'C:\Users\samuraiX\Desktop\Work\mp3towav\Music.mp3';
wavFileName = 'C:\Users\samuraiX\Desktop\Work\mp3towav\aMusic.wav';

signal   = audioread(mp3filename);
info = audioinfo(mp3filename);
Fs = info.SampleRate;

audiowrite(wavFileName, signal, Fs);

Use meaningful names for variables. audioread does not reply a file name.

filename = 'C:\Users\Rini Indrayani\Documents\MATLAB\Matlab\asli4.mp3';
signal   = audioread(filename);

When you get an error concerning a command, the first thing you should do is reading the documentation:

doc audiowrite

There you find that this is the minimal calling sequence:

audiowrite(filename,y,Fs)

So you need:

wavFileName = 'C:\Users\Rini Indrayani\Documents\MATLAB\Matlab\hasilwav4.wav';
audiowrite(wavFileName, signal, 44100);

if this is the right frequency. You can find this by audioinfo:

info = audioinfo(filename);
info.SampleRate

Summary: Do not guess how the commands work, but read the instructions in the help or doc text.

Use mp3read from https://in.mathworks.com/matlabcentral/fileexchange/6152-mp3write-and-mp3read...and then you have data in hand..try converting it to .wav.

For linux there is no good package

? audioread() and audiowrite() should work in Linux. However, with some releases of MATLAB and some versions of Linux, you might have conflicts with gstreamer versions and so might need to install a different version of gstreamer.
