Operation Manual

266 Pinnacle Studio 9
Type: In most cases, you will choose either PCM
(Pulse Code Modulation) or ADPCM (Adaptive Delta
PCM).
Channels: You may choose between
8- and 16-bit mono and stereo sound.
Sound quality and file size increases
when you add a second channel or increase bit depth.
Sample rate: Digital audio is
produced by taking regular instaneous
samples of the continuous analog
waveform. The more samples, the better the sound. For
example, audio CDs are recorded at 44 kHz, 16-bit
stereo. Audio can be sampled at frequencies as low as
11 kHz for many digital uses, particularly for speech.
