In theory the maximum gain cut required in Inguz is equal to the maximum boost being applied by the DRC correction curve. In practice, if you see any "clipping" in the Inguz log, then the DRC boost is exceeding the fixed cut AND when the excess is added to the music, the level (occasionally) exceeds 0dB. For example: 1) cut -16dB 2) DRC boost 18dB 3) peak level of track 0dB net result: some peaks will clip as the DRC will tray aand fail to boost their level to +2dB. By the way, check that you have the Inguz "flatness" setting set to 10... this will ensure that the correction filter from AL is being fully utilised. This should be the default, but I'm not sure if it is. See here: http://inguzaudio.com/blog/2007/09/17/flatness/ At the moment my advice is to adjust inguzdsp.exe.config for minimal clipping. Do not manipulate the AL correction curve up/down, leave it where AL puts it. Listen to some quite tracks. Does everything sound OK? I'll have to look at the DR plugin's RMS levels vs replaygain - that will have to wait until tonight... -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
