This is an 8-layer diode-based VCA audio compressor PCB Design that works in mono.
The compressor has LED-based gain reduction metering, input gain preamplification control, output gain control, and a fast-attack switch akin to the SSL channel-strip compressors.
Included is a full-wave rectifier module I published to the library which is connected to a peak detector block for the attack and release implementation.
The module is to be powered by a regular outlet.
A high performance CODEC consisting of a 2-ch ADC, 2-ch DAC, microphone amplifier, headphone amplifier, digital sound effects, analog mixing, and gain functions.
This is a peak detector circuit. It comprises of a full-wave rectifier to ensure that both positive and negative peaks are accounted for when taking measurement of the signal peak.
It has a response adjust switch terminal that can be used further to determine detection speed.
