Low Volume Buzzing and Jack Question
I have been using Ardour for several weeks now and I am loving it. I read the floss manual and feel like I have a decent handle on Ardour now. Unfortunately I am completely lost when it comes to Jack. Is there any place someone can refer me that has documentation that will explain Jack to me? This brings me to my other question...
I was recording something that is soft today, and when playing it back there was a buzzing noise (Yes I checked the room and instrument), but only when I was playing. If there was silence in the piece there was no buzzing noise. I could only hear it if I cranked up the volume, but it is pretty apparent with head phones. It was also present after I exported. This is the raw recording, I have not added any plugins to it I suspect maybe my Jack setting are wrong, which is why I asked the previous question. Or is this normal?
I would appreciate any help. I have a link for both a wav and mp3 of what I recorded, and I will provide as much information about the laptop I am using to record and its Jack settings. (QjackCtl)
Laptop: Aspire 5538, AMD Athlon 64 X2 1.2 GHz, 4 GB Memory
Audio Interface: M-Audio MobilePre
Ardour 2.8 with Ubuntu Studio
Jack Settings: First of all, made sure I selected my MobilePre
Realtime is checked
Sample Rate: 48k
Port Maximum: 256
Timeout (msec) 500
Start Delay (secs): 2
Input Channels: Default
Output Channels: Default
Input Latency: Default
Output Latency: Default
Latency: 42.7 (I have read 5 msec is not a bit deal, I take it 42.7 is?)
I am sorry if I listed any non essential information. Thank you for any help you can provide!
