Mono/Stereo options
* a Wave file with better sound quality requires a larger storage space because of it's higher sampling rate and size.

Mixing:

When mixing 8 bit data with 16 bit wave data, convert attributes via status bar.

Recording a new audio file:

Menu > File > New
Select: sampling rate, bit depth, recording device, playback device.
Menu > Audio > Record
File > Save
Enter the new file name and then click Save button

Invert Waveform:

Task > Invert Waveform > (select channels) > OK
This specific effect inverts the Waveform along it's horizontal axis.
*tips: you can create an unusual effect if you invert only one channel of a Stereo file.

Pan Left-to-Right or Pan Right-to-Left:

this effect applies to the Stereo files only.
*tips: This feature is useful if you want to simulate movement of a sound source from one end of the sound stage to the other.

Phase shift:
*tips: You can convert a Mono audio file to a Stereo audio file and apply this phase shift-effect. This will give the converted Mono file a 'pseudo-stereo effect'.

Volume:

Task > Volume
magnitude greater than 100 %, increase the Volume.
magnitude less than 100 %, decrease the Volume.
(Stereo = effects both the channels).
