Hi folks,

I recently had Fedora 14 installed on a modern enough Dell Optiplex (GX280 I think) tower. I decided I'd include KDE in the installation.

The purpose of this machine was to record multiple audio streams with rotter and JACK. Rotter transcodes the audio streams on-the-fly. I had the machine hooked up to an M-Audio Delta 1010 with all 8 analogue inputs being captured by rotter (twice in fact - in mp3 and mp2).

Anyways, the reason I'm posting is this: When I installed a much more minimal version of CentOS 5.5 on the exact same box, the audio files that were recorded by rotter had lots of glitches.

Both distributions were the 64-bit editions and as I said, the CentOs install was much more minimal - no X, much fewer services running (the output of pstree fits on one screen!)

I overcame the glitching problems by increasing the number of JACK periods from 2 to 4.

I will be investigating this further over the coming week or two - if I find anything I'll post back. If you know of what might might be causing the problems, I would love to hear from you.

Fedora is a bleeding edge test bed for RHEL, and therefore CentOS. CentOS is more reliable, but the software is getting outdated. CentOS has really been dragging their feet with releasing the 6 series. Maybe try the Beta of Scientic Linux 6 (another RHEL clone)?

Hi,

I'm working on a similar setup, can you please describe how you configure rotter to record each of the 8 line in in separate files?
