Audio setup
Once you have the audio card properly installed, there are a few settings you need to become familiar with. The most important parameter is
buffer size. Its value is proportional to latency, which is a time delay due to the computer processing the sound. The time is not dependent on the
complexity of the algorithm, but rather on the size of buffers and sampling rate. However, if you have a lot of effects and the processor load is
very high, a small buffer size may not work. In this case, increase the buffer size to the maximum acceptable value. If you play a chord on a guitar
connected to computer, and the output sounds delayed, the size of buffers should be decreased.
Open the Preferences dialog and set up the audio:
Windows:
1.
Select the device driver of your audio card from the Device selector (e.g. M-Audio JamLab).
2.
Then select the required Sample rate (frequency) from the list of supported rates. For most cases, a sample rate of 44.1kHz or 48kHz is
recommended. Lower rates decrease sound quality while higher rates increase processor load.
3.
Select stereo Input and Output connections from the available channels. For the Input, select where your guitar is connected; for the
Output, select where your amplifier is connected.
4.
For additional settings, launch your sound card's Control Panel. This will generally allow you to set buffer size. (You may need to restart
the application before the changes take effect.)
5.
Check the Latency information. For the best experience, it should be less than 20 ms.
NOTE: Sample rates selected here affect the selection of files that can be played back by Track Player.
Macintosh:
1.
Select devices for Input and Output from the Device boxes (e.g. M-Audio JamLab).
2.
Select required Format.
3.
Select channel pairs for Input and Output.
4.
Select required Buffer size.
