The positioning of the largest component, the audio jack, determined the placement of the remaining subsystems/components. The LM386 and its associated components fit right above the jack. Its large output capacitor then was positioned to the right of it. This left the lower right of the board for the envelope follower circuitry.
BMC 75. Envelope Follower - BARTON MUSICAL CIRCUITS

Envelope Follower. BMC 75. Envelope Follower. This module converts an audio input to a control voltage output with the control voltage corresponding to the amplitude of the input signal known as an envelope. Most envelope follower designs use a rectifier followed by a low-pass filter, this design uses a track and hold circuit to capture the envelope quickly and accurately.

Envelope Circuits: a simple AR design using op amps. A very simple Attack-Release envelope generator can be built with a dual op amp and just a handful of extra components. The input stage is basically the same as my op amp gate buffer, with only its output resistor changed; the rest is a simple low-pass resistor/capacitor setup with an output ...

The three functions are: Processing an audio signal such that it’s negative component when input to an op amp, does not harm it. Implement an envelope detector or follower. Amplify the signal so that it’s full range of the op amp used. Ive simulated circuits that do 2 before 3 and 3 before 2.

The idea of a voltage follower is rather straightforward. It consists of a rectifier circuit and you put the resulting waveform through a low pass filter to smoothen it out. You get a voltage on the other end which follows, more or less, the amplitude of the input waveform. The sole user control being the low-pass frequency.

LZX Industries Sensory Translator. The LZX Sensory Translator is a five-channel envelope follower module. Since each of the module’s channels is essentially a band passed frequency band, the resulting control voltage evolves from the volume of each band.

THE CIRCUIT BOARD The 9753 Envelope Follower is built on a double-sided circuit board. Note the “top” side of the board has the connector and control placement designators. Surface-mounted components are on the “bottom” of the board. Install parts to the top of the board and solder them on the bottom. TOOLS

The same envelope follower circuit used with a transistor as the control element may well result in considerable audible ripple unless the decay period is deliberately smoothed out with additional circuitry or larger value capacitors. The pros and cons of control elements are described in more detail in a section below.
Envelope detector - Wikipedia
https://en.wikipedia.org/wiki/Envelope_detector
In these circuits, the envelope follower is part of what is known as the "side chain", a circuit which describes some characteristic of the input, in this case its volume. Both expanders and compressors use the envelope's output voltage to control the gain of an amplifier.
