For a few months now I've been using Audacity with an on-board sound circuit, the ASUS A7N8X motherboard's onboard AC97 audio controller. It's been OK, but maybe I can get a better sound with an M-Audio Audiophile 24/96. I got one used, with no documentation, and I can't see any at the M-Audio site either. My problem is I don't understand the KMix mixer for the Audiophile 24/96. I'm just a simple guitar player, not an audio technician. The AC97's mixer with it's Volume, PCM, LineIN, and LineGain ... it was easy to figure out. But this mixer lists stuff I've no idea what it means. Could anyone tell me what these KMix settings do? Output: DAC ( two of them ) Multi ( 10 of them ) MultiTrackPeak MultiTrackVolumeRate ( I've got the Audiophile's two RCA outputs plugged into my sterio amp ) Input: IEC 958 Multi ( two of them ) DAC ( two of them... shouldn't these be ADC ? ) H / W Multi ( two of them ) MultiTrackVolume Rate Switches: IEC 958 ( two of them set to PCM Out ) Deemphasis ( set to off ) H / W ( two of them set to PCM Out ) MultiTrack Internal Clock ( set to 44100 ) MultiTrack Internal Clock Default ( set to 44100 ) And one last question: Is this M-Audio Audiophile 24/96 sound card really any good? If not, I may as well remove it and use what I already understand. Thank you for your patience, and ANY information would be very welcome!
