Hi all, (sorry for late reply but my email server was down 11/5 - 17/5) thanks for the info Marko, could you explain how though I would play the 4bit sample? I just don't know enough about the SID - I can program notes.. but digital sounds? Is it just a case of volume modulation? - Nick > -----Original Message----- > From: Marko Mäkelä [SMTP:msmakela@cc.hut.fi] > Sent: Wednesday, 10 May 2000 15:21 > To: cbm-hackers@dot.tcm.hut.fi > Subject: Re: Converting/Playing WAV files > > On Wed, 10 May 2000, COPLIN, Nicholas. wrote: > > > Can any one recommend a PC tool to convert WAV sound files into > digitised > > sound samples for the C64. > > As far as I know, the WAV format consists of uncompressed raw audio > samples.
