Multiplication factor for input samples. Parameter <atten> is identical with <inCalibrate> of AT^SNFI. Formula used to calculate microphone attenuation (negative gain):

Gain in dB = 20 * log(<atten>/32768)

0...32767(P)...65535
0	Microphone is muted
32767	No attenuation on the microphone path

Notes

•The command is provided for compatibility with M20 and is a subset of AT^SNFI. The parameter <inCali- brate> of AT^SNFI is identical with <atten> of AT^SNFA.

•To make the changes persistent use AT^SNFW.

Example
