Hi Howard,

thank you for testing the patches.

Hi,

I applied these to Mark's screamer branch to create a new OSX build. Testing was done by playing system sounds, and an MP3/Internet radio with QuickTime/iTunes. With or without 6dB, the max volume is way out of my comfort zone. I hear no real difference in quality compared to a build from the

It wasn't my intention to annoy your neighbours. On my computer I use an analog output for playback. Clipping happens before DA conversion, so I can use the volume control on the amplifier to have normal volume levels.

current screamer branch. If any, it might sound a bit better. That means there still is some minimal crackling (clipping?) in the high volume parts of the

Crackling and clipping are two different things. Crackling is normally a timing problem where audio samples aren't delivered in time. Clipping produces harmonic distortions. For example a clipped sine wave will sound metallic because of the harmonic distortions. The difference between a clipped and a pure sine wave is clearly audible.

audio I played with OSX guests, not Mac OS 9.x guests.  

So as there is no regression,
