Audio Electronics
Audio Electronics deals with the circuits that are designed for converting sound/pressure wave signals to electrical signals, or vise versa. These circuits are used to processes and manipulate audio signals to design different types of audio amplifiers, audio mixers, frequency controllers etc..
This section consists of a huge collection of audio circuits with schematics and detailed explanation, to help you build Audio projects and use them for your Audio designs.
