Version 2.40 of our venue server software introduced soft gain limiting for our gain adjustment function. This is for use in cases where the audio volume of a particular source is too low and must be boosted. The gain is adjustable in 6 dB increments. That is, every increment is roughly equivalent to moving twice as close to an audio source. The venue servers take in line-level inputs, but not all sources conform. Here are the gain curves that we have implemented. The soft limiting make the audio output sound more pleasant when over-driven.
The control is done most easily by our Cloud Server. Here are what the controls look like. “0” corresponds to 0 dB, “1” to +6 dB, etc., up to +24 dB.
