That's not universally true - for example, with microphones you really do want to have substantial amplification before the ADC sees them, otherwise you'll at best get poor resolution due to the signal being nowhere near full scale. Sometimes this will be done by a fixed gain stage that isn't visible to software, but not always. Things in the digital domain also tend to be at least equivalent to doing the work in the CPU. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
