I am currently trying to do some simulations of a graphic equalizer that I
am designing using FIR filters and I am having problem reading in wav files that are just standard music. I am getting an error 85 and it says it is in the "wrong format". Is there a proper way to convert a mp3, or audio track to wav so that I can read it in and record the outputs to another wav file? Thanks Craig |

Hi Craig, I'm interested to know more about your FIR equaliser, are you designing a multi-rate system?

To use wavread in MATLAB the audio file should be in Microsoft WAVE sound format. If it is a normal PCM file you can simply use fread without any problem if you already know the number of bits per sample. For converting mp3 to wave, in some audio players the output can be configured to a file instead of audio devces. In Winamp you can do this by going to options->preferences->output and choosing disk writer plugin. I think this produces a wave file. You can also search google for mp3 to wave conversion. But most programs might be commercial.

You could use "Goldwave" for this purpose. WAV <-> RAW MP3 <-> WAV You can do transformation to any popular audio format. visit www.goldwave.com for additional details.
