Depends on what type of setup you have. In mine, the soundcard is wired to the multitrack ins/outs of an external mixer, so I want calibrated levels, and the card's gain controls are set up once at boot time and never touched afterwards. To be shure, I removed all apps that modify these settings. Anyway with 24 bit converters, and floating point data in the apps, the extra quantisation noise introduced by digital volume control is less that what you can hear. -- FA ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
