Snes Audio emulation accuracy in 2020

[ribos]

Hi, does anyone know if the audio emulation of bsnes based audio plugins can be considered perfectly accurate compared to the real hardware ?, i wanted to make some game rips and i want to make sure if it's identical to real hardware (at 99%+, or even 100%) before anything else...

As far as I know, SNES audio emulation has been bit-perfect since blargg's DSP core many years ago. Near eventually switched bsnes to his own, more accurate DSP implementation, so I'd say anything bsnes-based would be fine.

Thank you , if anyone else know about that or have some more informations, don't hesitate to share it.

Afaik bsnes/higan is bit-perfect to a real SNES' digital output before the DAC. (Though this might differ if you enable compilation with a different audio core?)

The SNES also has a low-pass filter, which afaik isn't emulated.

No emulator has perfect audio emulation, but the things I've hit are more about glitches, not how it sounds. "it crashes when you do this" "this causes a small blip in the sound".

That isn't true. Altough some people seem to think so, probably due to the (emulated) digital gaussian filter, or because TV-sets tend to have better bass speakers than cheap PC speakers. See also here viewtopic.php?t=12025

Thanks guys, so if i'ts bit-perfect to real hardware before the DAC (assuming i using Game Emu Player with foobar2000 with right options) it would be perfect for me (that's precisely what i look for).

Ok, as long as potential glitches are easily noticeable (in order to fix them or use anither way of ripping these tracks) and if the glitches don't affect the whole track, i'ts all right.

i think it would be all good (bit-perfect before DAC and if that's more or less what i wrote about glitches)

I've found this project.
Seems interesting if you can borrow or get an APU from a real SNES.
