Alright! SO! I’ve been banging my head on this for the past few weeks now, so it’s time to throw it to you guys. This might not even be an Audacity issue, in which case feel free to direct me to whatever other helps might be helpful that you know of.
I’m using a US122 MKII USB Interface, with an ADK A-51 Condenser Microphone. I know how to do basic stuff in Audacity. Sadly, I don’t know how to stop a Matrix-phone-style buzzing from randomly (for no apparent reason) infecting my sound. It’s not ambient noise because it only happens when it decides to, usually after I’ve been noodling for a bit, and sometimes it decides to record nothing at all. It’s not feedback because I’ve got headphones on. I’ve tried Soundbooth as well, same problem (the glitchy force is a bit stronger with that one… so much so that every time I close the program it wants to send a crash report… but that’s a different story).
The first half is a successful clip. The second half, I got through 3 tracks and then obviously the ad lib track becomes horrifically unbearable to listen to.
My guess (and it is only a guess) is that the Tascam interface is faulty.
It could possibly be electrical interference, but it seems to follow the audio to some extent which would not be the case if it were just interference.
I’d suggest that you try using the Tascam in other locations and on a different computer and with a different microphone. If you get the same problem then it is pointing firmly at the Tascam.
Crash Report would indicate that there is something wrong with the computer interfaces or bitstream. Are you going through a USB hub anywhere? Audio hates going through hubs. Home Runs or dedicated runs to the computer always.
Exercise the connectors. Shut down the computer and unplug and replug all the USB connections – both ends of all the cables, several times. Restart the computer and Audacity.
