iSK CRU-1 USB Studio Condenser Microphone - Recording PC Mic
Seems to work fine on Windows, but on my LInux machine, the audio signal is weirdly panned depending on which app I use.
- Discord desktop app picks up the mic fine, and transmits voice as a mono signal
- Chromium / Chrome gets a quite low signal from the mic, and it is almost entirely to the left when gain sliders are locked
- Audacity gets a straight signal on the left channel and a weirdly muted copy of the signal on the right when stereo input is selected.
- Audacity happily reads it as a mono input, which gives a very clear signal.
- OBS Studio also sees it as a mono signal which can be panned to wherever you want.
- Getting it configured under Jack 2 was a bit of a struggle, but it gave excellent clear signals once Jack2 was configured, and I could remap the left channel across to both channels easily. I could not get PulseAudio to accept the Jack 2 input in order to make it available to desktop apps.
Trying to adjust the gain sliders for left and right channels separately gives very strange results. Dropping the right channel gain to minus infinity to completely mute it also mutes the left channel. Raising the gain on the right channel to bring the two channels to the same level gives a fairly quiet signal, slightly distorted on the right channel. There is no way to get a strong signal on just the left channel, and I have not been able to make the signal mono generally in ALSA / PulseAudio.
I wouldn't recommend this for general computing use on Linux, though it seems fine for recording audio in Audacity and most streaming purposes.
