In all honesty here, truth told, the PS1 was an audio powerhouse and I don't think the N64 had any audio advantage. Sony made sure the PS1 was compliant to the CD-I formats as well as building on top of the amazing SNES Audio Chip they designed with a much more wider handling MODI system for modular music. Developers on the PS1 had a LOT of options to explore which was the difference compared to say Sega CD, etc, before it, the PS1 could handle multiple types being handled at the same time if a developer wanted from pre-loading sound banks whilst streaming from a compressed source to fast track switching and full CD-DA uncompressed if required.I knew that I've missed some things when I was making the list and was wondering what cuold be in the place of what was removed,
Audio is overlooked these days and no one really cares about it but back then Sony created a massive shift in providing devs with various audio options to take advantage of and even the early PlayStation models had a top line DAC which even caused music snobs to pick up a PS1 just to attach to Hi-Fi units and use it for CD playback.
It would've been the later end titles, I think VibRibbon perhaps? It would've used something in line with the Wave-MP3 format (which is basically MP3 with wave formatted header) but it was limited in what bitrates it could handle and even then the process/trade-off made most switch back to XA instead (which to be fair holds up better than early MP3's of that era).Out of curiosity, what's the case when PS1 make use of MP3?
