Aiki, FreeBSD forums member Phishfry recommended an M-Audio "MobilePre USB" device to me for this purpose. He found one on eBay for $35 and sent me the link. I've used it with audacity on three (very different) computers running 11.1-RELEASE, and it worked really well on all of them. I now have two microphones attached, and it mixes them together in to one mono channel for audacity to record. A sticker on the bottom of this device reads: PID/Ver: 200F Firmware: V1.03 Date: 11-2008 PN: AU02-071G1 SN: 071G158B03130 On one of my computers it was necessary for me to manually select the recording source, just because it wasn't the default, in audacity. And I did toy around with mixer(1) some. But other than that, it just worked. I don't have enough experience with listening for sound quality to really comment on that aspect of it, but it sounds great to me. I use it almost every single day, and the idea of upgrading to anything fancier hasn't really crossed my mind. It also tends to want gain maxed out with my SM58 microphones, or at 75% or so; the device doesn't seem to support enough amplification to exceed what's required by much, if any. 'not sure why, but this seems to be less noticable with two microphones attached than with only one. It shows up like this when I plug it in: ugen0.7: at usbus0 uaudio0 on uhub4 uaudio0: on usbus0 uaudio0: Play: 48000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 44100 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 32000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 24000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 22050 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 16000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 11025 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Play: 8000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 48000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 44100 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 32000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 24000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 22050 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 16000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 11025 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: Record: 8000 Hz, 2 ch, 16-bit S-LE PCM format, 2x8ms buffer. uaudio0: No MIDI sequencer. pcm2: on uaudio0 uaudio0: No HID volume keys found. And it shows up like this also (it's the "USB audio" entry): % cat /dev/sndstat Installed devices: pcm0: (play) pcm1: (play) pcm2: (play/rec) default No devices installed from userspace. Happy days to you Aiki, Robroy
