can somebody recommend some software to do this ( if it's not freeware , also a link to a torrent :) )

bump

The first thing is noticed is the low quality of the music so converting that to Wav isn't going to sound very good but passable.. i.e WAV full specto would be around 22khz where this will be 17/18 with a dip around 13... anyway

Just add the file and deselect video and rip to audio.
also where it says 48hz turn that into 44,1hz
with the audio use windows to burn to disc..

I know the source quality is not the best , but its all that's available
the better sources are all dead torrents
thanks anyway for youre help and info

Try using Switch Audio File Converter

Just convert it using Freemake audio converter.
It's probably the easiest and best software that I've used to download and convert.

(Note that the Freemake audio converter is just for converting audio to a new format. Get the regular converter for this, not the audio converter).
Hope this helps.
