I am on a Macbook Pro: Processor: 2 GHz Intel Core i7 Memory: 8 GB 1333 MHz DDR3 Graphics: Intel HD Graphics 3000 512 MB Software: OS X 10.8.2 (12C60)
I am recording using Rode NT1, Apogee Duet Firewire, Ableton Live 8.3.4
My Apogee creates random crackling sounds while recording, and it does not only affect the monitor, but also records that artifact. It is impossible to use the card for recording. I looked around the internet, disabled all other apps, changed buffer size, sample rate, etc. I did everything I could but to no avail. Here is a zoomed in image of an example artifact.
It is that spike right around the middle of the image.
If anyone has any idea about this problem I would be very happy. It has really stopped all our progress.
Latest driver is installed so there is nothing I can do on that front. I have tried 2 different firewire cables. same problem with both of them. mic cable is fine, just tested again to be sure.
On the other hand, I would really love to learn what does that spike mean. I mean do any of you guys have an explanation along the lines of "buffered sample arrives late and audio interface skips a few buffers." I just made that up of course but I guess you see what I mean.
Yeah driver or buffer too low is usual reason for causing pops and crackles... never had that problem with my Duet to be honest... might happen once in a while during play back but a restart would solve it... I still think its software related... but if you've reinstalled the latest drivers then maybe its something else.
