.PCM files on Sega CD


Recommended Posts

head to http://us.geocities.com/bnvaldez/soundroom.htm and download lun2_pcm.zip

with this you can convert it to a WAV using the app. 8khz freq should give you the original speed.

based on the converted wav, the properties are:

Bit rate: 64kbps

Audio sample size: 8 bit

Channels: 1 (mono)

Audio sample rate: 8kHz

Audio format: PCM

from what I read about PCM (sometime ago now so I may not recall exactly but) is basically like wav, but the headers/storage format are different for use under windows. also, in the conversion the size basically reduces half it size, meaning the orig PCM may indeed be stereo and one channel is being lost in the conversion..

Not sure how you can convert a wav back to the genesis PCM format... but with some luck an app may exist (be it dos based) that may allow you to do such a thing.

Thanks, that's a lot more then I expected to find out about the files. Better then any info I have found out already. :D

Read the PCM section here:

and be sure to grab the PDF which details an equivalent chip used:

There's some good PCM background here, just not much for the specifics of the Sega CD:
