Camtasia (Windows): Best audio format for recording

The default audio format for Recorder is PCM 44.100kHz, 16 bit, stereo.  This is the recommended audio format for recording.

Due to restrictions of DirectShow, only the following sample rates should be used:

8.000kHz
11.025kHz
22.050kHz
44.100kHz

If other sample rates are used, they must be converted to one of the above sample rates for playback or production.  This change in sample rate can cause audio quality degradation.

Use good quality audio, such as the default settings, for the original recording.  Increasing the audio quality at production time will never improve the original quality, and in some cases may cause the quality to degrade.

If possible, avoid mixing audio formats, i.e. sample rates, stereo / mono, on the timeline.  Mixing stereo and mono clips on the timeline may cause audio amplitude variations in the finished production.
