Audio Setting Window

You can customize video profiles for output video by using Profile Editor. In this window, you could configure some audio parameters: Channels, Sample Rate, Bit rate.

1.Channels

With Channels setting, you can switch audio parameters between 'Stereo' and 'Mono'..

2.Sample Rate

Sample Rate is the rate at which samples of an Analogue signal are taken to create a Digital image of that signal. Higher sample rates give higher audio quality at the expense of larger audio file size. Lower sample rates save disk space but result in poorer audio quality.

3.Bit rate

Bit rate can be defined automatically according to hardware environment. You also can specify it, after canceling the check box - 'Auto set audio bit rate'. If you select higher bit rate, you will receive better sound but with more physical space one second of audio takes in bits.
