https://www.circuitstoday.com/audio-oscillators
An introduction to Audio Oscillators also known as RC Oscillators. So far, we have considered the oscillators which use L-C tuned circuit that causes a phase shift of 180° due to inductive or capacitive coupling in addition to a 180° phase shift produced by the transistor itself. The oscillators employing L-C elements, called the L-C oscillators, are very popular for …

The circuit diagram given above shows a variable audio frequency oscillator using ICL8038. Such a circuit is very useful while testing audio related projects. The frequency range of this circuit is 20Hz to 20KHz. POT R6 can be used for adjusting the frequency while POT R9 can be used for adjusting the distortion.
Simple Oscillator Circuits
https://makingcircuits.com/blog/simple-oscillator-circuits/
Simple Relaxation Oscillator using a Single BJT. The negative resistance area of a reverse-biased silicon transistor can be applied in a relaxation oscillator circuit. Its benefit is that an excess transistor is utilized instead of a UJT, which is generally more expensive, and it does deliver a minimum of components.

C. Tuned Oscillator Circuits Tuned Oscillators use a parallel LC resonant circuit (LC tank) to provide the oscillations. There are two common types: • Colpitts – The resonant circuit is an inductor and two capacitors. •Hartley– The resonant circuit is a tapped inductor or two inductors and one capacitor.
Audio Test Oscillator
https://www.sound-au.com/project22.htm
Introduction. As a piece of test equipment, an audio oscillator has to be considered essential for anyone working in with hi-fi gear. Together with an audio millivoltmeter (as described in Project 16), and even better if you have access to an oscilloscope, you will be able to make proper measurements on everything from preamps, RIAA equalisation stages (for vinyl disks), tone …
