Audio channel 1 name.
The name or description for the first sound channel.
Audio channel 2 name.
The name or description for the second sound channel.
Audio sample rate.
Increasing the audio sample rate generally improves the quality of
the higher frequency component of the recorded sound. Increasing the sample rate will
also increase the space required to store the recorded sound. Sample rates available are
11 KHz, 22 KHz, and 44 KHz. Typically, 11 KHz is effective in most monitoring
situations (the default value).
Audio sample resolution.
The sample resolution is the second audio quality parameter.
Two options — 8-bit and 16-bit — are provided. While 16-bit recording provides
superior audio quality, most audio surveillance applications will be satisfactory at 8-bit
resolution. Increasing the resolution to 16-bit will also increase the space required to
store the recorded audio channels.
The MobileView recorder uses only the WAV sound compression algorithm. The
compression algorithm selection settings are disabled. The associated compression level is
preset to provide the best audio standard and space efficiency.
