Description |
---|---|
Device |
Distinguishing name/model/Id of the device plugged into the input. |
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. |
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. |
