M-Audio DMAN [29/52] The user defined audio transport button

ADPCM - Provides 4:1 compression compared to 16-bit

PCM format. The compression means this format uses

less disk space but causes degradation in playback

quality.

m-Law - Provides 2:1 compression compared to PCM

format.

A-Law - Provides 2:1 compression compared to PCM

format.

Channels - Mono requires half the disk storage space as

stereo, and usually provides sufficient quality for voice

recordings.

Sample Rate (kHz) - Higher sample rates provide better

sound quality and require more disk storage space. Typical

sample rates are 11.025 kHz (for voice), 22.05 kHz (for

medium-fidelity), and 44.1 kHz (for high-fidelity CD quality

recording). 48 kHz is what some professional digital

recording systems use and offers the best fidelity of all,

although only a marginal amount better than using a 44.1

kHz sample rate.

Bits - Determines the resolution of the data. The higher the

resolution, the better the sound quality. Select 16-bit for

higher quality recording. Recording in 8-bit format can

sometimes cause distortion – or a hissing sound – during

playback. The Dither option in the Audio Input Control

panel may help reduce distortion caused by 8-bit recording.
