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 ...
Audio Envelope-Generating Circuit for Use with the MSGEQ7
https://www.eeweb.com/audio-envelope-generating-circuit-for-use-with-the-msgeq7/
Envelope-generating circuit In physics and engineering, the “envelope” of an oscillating signal is a smooth curve outlining its extremes. The envelope thus generalizes the concept of a constant amplitude. So what we want to do is create a circuit that accepts the audio signal coming out of our microphone BOB as input and then outputs a ...

Step 4: Audio Envelope Follower Circuit. This portion of the circuit starts with audio input corresponding to the spoken output. It is then scaled up to almost the supply voltage (less the limitation of the op amp). This is then sent through an RC network to smooth out the signal to DC.

Audio Power Amplifiers with TPS61088 Designs Overview Design Features This reference design delivers an envelope-tracking power supply circuit for audio power amplifier (PA) with TPS61088. By adding an audio envelope signal to the FB pin, the TPS61088’s output voltage can change in accordance with the envelope of the audio signal.
Sound Envelopes - Teach Me Audio

Signal Envelope; Differing Sounds; Hearing Envelopes; Signal Envelope. The envelope of a sound can be measured in four ways: 1. Attack – The attack is the portion of the envelope that represents the time taken for the amplitude to reach its maximum level. Essentially it is the initial build-up of a sound.

https://www.ti.com/lit/pdf/tidueo5
This reference design delivers an envelope-tracking power supply circuit for mid-power audio-power amplifier (PA) applications with TI's TPS43061 boost controller. By adding an audio envelope signal to the FB pin, the output voltage of the boost converter can change in accordance with the envelope of the audio signal.
Audio Envelope Follower for Arduino | All About Circuits
https://forum.allaboutcircuits.com/threads/audio-envelope-follower-for-arduino.161136/
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.
Synth Schematics --::-- Envelope Generator ADSR
https://www.schmitzbits.de/adsr.html
The original circuit was found in the Music Machines diy-archives. Its a design by Barry Klein. I started to expand it from the Original AD-envelope to an ADSR envelope. Make sure you add a 2.2kOhms resistor in series with the Attack and Decay pots, this prevents clicking and an unwanted latchup condition for the flip-flop.
