How accurate is WinUAE OCS/ECS audio emulation?

Has anyone testes WinUAE audio against real hardware? Is it accurate enough to use for judging Amiga game and demo music by? For comparispn I dont consider DosBox OPL3 emulation to be accurate at all..

Yes. Paula is pure digital (Output is analog but it is output from internal D/A converter) and relatively simple. Emulation is cycle accurate but because there are many bad audio players (CPU delay loop "dma wait"), fast cpu modes don't emulate it fully and play the sound correctly even if real "too fast" CPU would have caused lost sample or repeat of old sample.

I guess WinUAE audio emulation it's nearly perfect

I made this try

I created MP3s from audio recording by WinUAE and compared these recordings to the MP3s of the SOAMC project

This project is a collection of MP3s recorded using the real hardware

So, in other words, i compared the emulated audio against the real audio and, surprise, no difference at all
