In the first show it worked fine, though I did have some xruns that caused audible glitches (just 2 or 3 and only in some tracks). during retracking I had a lot of trouble with xruns, but we did get a CD out the door... In the second live recording the machine ran for nearly an hour before exiting ardour due to too much disk activity. after that it was a bit of a struggle to get one song down without ardour stopping. However, don't dispare, all this has been fixed. How? firstly I upgraded from FC5 to FC6 which allowed me to change the motherboard setting for my SATA disks. I was getting ~5mb/s transfer, but with the motherboard in advnanced mode, I get >50Mb/s. NO more xruns. Just the other day I started on my 'tape transfer project' and recorded an entire cassette tape without a single xrun or any other issue. ok, only 2 tracks in this case, but no problems at all. In fact I'm tempted to get another tape deck and do 2 tapes at once (-: (note that I'm still running Ardour 2.1 on FC6 and later versions will be better, and in fact I have an FC7 and FC8 DVD right here for the purpose of upgding because Ardour 2.1 does crash for odd things, like pressing space bar to stop recording). At this point, I'd be happy to do an 8 track recording. For important live recordings I would not use a laptop, but instead a decent desktop with a RAID 0 array of at least 3 SATA2 disks for the audio files, with the system on another disk. don't forget to kill anacron before you start recording, it has the habit of starting disk intensive processes when you least need them. -- David http://iwr.ru.ac.za/~iwdf/ If you receive email saying "Send this to everyone you know", PLEASE pretend you don't know me. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
