both for mono or stereo.
6. Balanced/Unbalanced, selects the type of microphone input.
7. Display, selects the dynamic range of the display while recording is in progress.
8. Talk Thru, selects whether the recording input is passed on thru the play back.
9. FFT (pts), selects the bandwidths of the both FFT & spectrographic display frames.
10. Frequency Range, selects the frequency range of display.
11. Dynamic range, selects the dynamic range of display.
12. Freeze button, freezes the real time display and the recording. Toggle to unfreeze.
13. Pause button, will pause the recording. toggle to record again.
14. Record button, records audio to a temporary file onto the disk.
