So, what do Jorito and snout think, who wrote the comments mars originally posted?

Haven't found time for this yet. Also I'd like to set up a test case myself with a soundtrack I know well and already has MP3 recordings from real hardware (Bombaman).

Even if the discussion isnt finished yet and there are still things to find out, I'd say that the MoonSound emulation is very close to the real thing, and much closer than the PSG emulation is to the real analog PSG sound output. Whatever tracker or emulator I use, I'm always a little unsure of how the song will work on real machines. It's quite interesting, because the PSG is supposed to be an extremely simple little state machine circuit.

Just had a quick listen to the samples form yzi and Meits, and on my Macbook Pro speakers the difference between the emulators and the real thing is too close to call (apart from the second Meits tune that was distorted and is probably the real hardware recording because of that).

I'll have to do a good listen on my monitors and studio headphones later this week for more detail and I'd like to test it with a few Bombaman songs that I know very well to give a final conclusion, but so far yzi's conclusion sounds good.

At least the emulation is a lot better than plugging a real Moonsound in a One Chip MSX, that causes a lot of timing issues Smile

yzi, can you make a recording with a more recent openMSX release?

Ok, here's one more mysterious recording, this time from *penMSX 0.9.1 *mulator (name censored so you don't know what it is)

By the way, I think you should be able to hear the differences in the highest treble frequencies between emulators and the real machine. It may seem difficult at first, but think of it in terms of "where are the instruments located". Psychoacoustically (or something, I'm not an expert on the terms), the high frequencies are one way to change the perceived distance to the sound source. To make a sound seem further away from the listener, the primary means from a conventional mixing-desk-and-effect-processors sound engineering point of view are (1) attenuating its level (making it quieter), (2) dampening its high frequencies with EQ, and (3) increasing the relative amount of reverb compared to dry sound (more wet, less dry signal). That's why the frequency range somewhere around 8kHz is sometimes called "presence". In the real MSX recording, particularly the drum sounds feel like being very slightly more towards the back of the soundstage, because they're not as bright. It's a subtle difference, but it's there.

BTW, does anyone compared a Tecnobyte's Shockwave too? It features a much better DAC than the MoonSound, and a carefully designed analog circuitry to minimize background noise. Those should make some difference on the sound quality.

Meits and yzi: how does that (yzi's 4th) recording compare to the other recordings (made by yzi), in your opinion?

I think it's good. I don't feel the annoying tempo up/down thing. Though I didn't measure distances in the wave, just listened to it.

Oh well... listen to the sound starting at 2:29, is that OPL3 FM sounds of the MoonSound? Is it too loud in the 4th recording?
