Audio and Video

Term

Description

Device

Distinguishing name/model/Id of the device plugged into the input.
It will appear in Presets drop-down list.

Microphone

Distinguishing name/model/Id of microphone plugged into the input. For example, Olympus ME53M Lavalier. Or, it could help identify a "build-in" mic if part of a device, such as a video camera.
It will appear in Presets drop-down list.

Duration

Length of recording, usually in H:M:S (Hours:Minutes:Seconds).

Channels

Mono, stereo, or other.

Bit Depth

Audio bit depth is a number (like 16 or 24) which states how precisely the loudness of a signal can be recorded (dynamic range). Most recordings today should be done at 24 bits.

Sample Rate

The number of times per second that a sound wave is measured. A higher sampling rate provides a more faithful reproduction of the sound. The current acceptable standards are 44khz or 48khz; 96khz is considered ideal, as it will facilitate future noise-reduction processes.

Audio Bit Rate

Usually stated in kbps (kilobits per second), the number of bites per unit of time.

Video only

Term

Description

Video Bit Rate

The degree of sharpness of a computer-generated image as measured by the number of dots per linear inch in a hard-copy printout or the number of pixels across and down on a display screen. Examples: 176 x 144, or 800 x 600.

Frame Rate

Frames per second.
