Re: [hatari-devel] Fix for Falcon's noisy sound

[ Thread Index | Date Index | More Archives ]

I'm pretty sure your patch has also improved the sound in DSP mode.
IE : when I start hatari, I can see your patch in action with the "fix writepos" messages in the console. This means that sometimes, I could start a program with a DSP player when the write and read buffer where close to each other and the read buffer overwrote datas.
This also explain why it seemed to be random.

I've given a quick try to the DSP sound and it works nice too.

More tests tomorrow.

There's no more glitch in sound. The falcon emu has a major update now
for 2.0

I'll test DSP sound, and other case to be sure there's no regression,
but at a first try, it's a perfect patch.

Thanks a lot Nicolas.


regarding DSP sound, it should not break it, but it should not improve it either. In the case of MP2/MP3 replay using the DSP for audio decoding then we still need better cycle counting at the moment in Hatari, else program relying on precise cpu/dsp timing will not work correctly.

So, fix is for DMA sound only, but it should cover most of the use cases in games/demos.
