The ReaRack3 zip in the stash now contains an Audio<>MIDI module. This allows conversion of audio sound, audio control or MIDI CC signals from one to another.
In this module, for both Inputs and Outputs there is an option to choose Audio channels 1 & 2. If Audio 1 & 2 is selected as an input, the sound signal (-1 to 1) is converted to a control signal (0 to 1) and if selected as an output, control signals are converted to sound signals.
For audio input, there is an option to use the raw signal or to use the envelope of the signal. There is a gate setting (audio below the threshold will be zeroed) and there is a window size control for extracting the envelope. The default value will give a smooth envelope with a 10 Hz signal, but you may want to reduce the window for less latency if the input frequency is higher.
