Hello!
Here's my problem: when I record vocals, I always get these annoying artifacts - clicks and pops. AAARGH! They seem to occur especially around "f" and "v" sounds. Example, if I record someone - anyone - saying 'Phillips Phonographic Records', clicks will be introduced at any of the 'ph' sounds.
These clicks and pops occur regardless of
- vocalist
- recording w/without windscreen, popper
- which mic preamp I use (eg, UA LA610 and Focusrite 430mkii)
- different preamp gain settings (really quiet to really loud)
- mic impedence settings
- mic cable used
- mics used (414, tlm103, etc)
- sample/bit rates (44.1-16, 48-24, 96-24 etc)
- buffer sizes on audio card
- A/D converters used (Masterlink, MOTU HD192, etc)
- AC source
Additional info:
- the signal path: mic - mic pre - analog out - analog in on Alesis Masterlink or MOTU HD192
- the spikes created by the clicks can be seen on the recorded waveform
- the clicks can be heard on the input monitor
- the problem does not seem to come from the converters, as they convert without clicks when I convert/import audio from, say, a commercial CD.
- my guess is that these clicks are being created by the preamps, that maybe there's some kind of voltage mismatch, but I'm admittedly out of my depth here.
Any suggestions would be very much appreciated,
Michael
