Audio quality
Sets the audio quality depending on available
bandwidth. Sample rate must be same in both RRC
but coding can be different (more information can
be found in appendix-A Audio coding):
0 = A-law 8 kHz
1 = Linear 12 bits 8 kHz
2 = Linear 16 bits 8 kHz (default)
3 = A-law 12 kHz
4 = Linear 12 bits 12 kHz
5 = Linear 16 bits 12 kHz
6 = A-law 16 kHz
7 = Linear 12 bits 16 kHz
8 = Linear 16 bits 16 kHz
9 = A-law 24 kHz
10 = Linear 12 bits 24 kHz
11 = Linear 16 bits 24 kHz
12 = IMA ADPCM 4 bits 8 kHz
12 = IMA ADPCM 4 bits 16 kHz
Audio Dual-RX
Sets if LF from the Sub-RX should be sent as an
separate audio channel. Be aware of that this
doubles the need of Bandwidth. (Only available in
the (s) version.)
Codec out gain
Sets the attenuation for the audio output, in 255
steps and 0.5 dB per step. Should always be set to
255.
255 = no attenuation (default)
254 = -0.5 dB
253 = -1.0 dB
…
0 = max attenuation
Codec inp gain
Sets the gain for the audio input in 63 steps and
0.75 dB per step. Should be 18 at Control-RRC for
high level electret microphones and should always
be 0 at Radio-RRC.
0 = default Radio-RRC
…
18 = default Control-RRC
…
63 = max value
