Report Recreating Retro Sound Effects in Music Composition & Production Posted February 12, 2015 Do you mean just isolate the sounds from the background music, or split up the sound into individual components if it's multichannel?If it's the former, a lot of old games including Sonic have the benefit on a sound test in the options. I have been looking for the individual component option, as I have been able to find Mega Drive sound effects which have come from sound test options. I have been able to slow the sounds down using Audacity and change tempo but it is hard to breakdown individual tones! Thanks for the info Anorax! I will certainly look into that for SNES!
