I am trying to send an audio file over a channel using OFDM. But it keeps giving me an error at the very start:
% Read the audio file
[y, Fs] = audioread('file.wav');
binaryData = dec2bin(quantize(y, 8));
AfterwardsI use PSK modulation, then I convert it from Serial to paralell. And comes IFFT. But here at this line I get this error:
Error using quantize
Inputs of class 'double' are not supported.
I don't understand how I can fix this problem. I tried using int8 but had no luck as I received more errors.
If I am approaching the problem in a wrong way, please tell.
I am somewhat new at everything. I would appretiate any help given.

Hi Harry,
The first parameter of quantize() should be a quantizer object.
Please refer the documentation for more details
Hope it helps.
