Usb audio interface for linux
Qjackctl, cadence, patchage and studio-controls-git AUR can all be used to as GUIs to monitor JACK's status and simplify its configuration.
Start jack with the options you just found out: Also, you may like to set maximum priority (at least 10 lower than system limits defined in /etc/security/limits.d/nf) the highest is for the device itself). Others common rates include 44100 Hz and 96000 Hz.Īlmost always, when recording or sequencing with external gear is concerned, realtime is a must.
A common sample rate across many of today's devices is 48000 Hz. You will be looking for rates or VRA in Extended ID. Replace card0 and codec#0 depending on what you have. To check what sample and bit rates your device supports: Commonly used values are: 256/3, 256/2, 128/3.Īlso, the sample rate must match the hardware sample rate. For onboard and USB devices, try Periods/Buffer = 3. The aim here is to find the best possible combination of buffer size and periods, given the hardware you have.
