This is a complete microphone signal conditioning project. Designed primarily for voice-band applications, this project provides amplification, limiting, variable compression, and noise gate. User-adjustable compression ratio, noise gate threshold, and two different fixed gains optimize...

The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC, Project supports single-ended or...

Have you heard about RF listeners earlier? If not, Maker Wolf has designed an RF listener that lets you hear the RF sources. When we look at the RF receivers, it usually singles out a particular frequency and decodes it. But in this project, the handheld device takes a range of...

The primary role of this project is to convert a differential input audio signal into a single-ended output signal while rejecting noise that is common to both inputs (common-mode noise). The circuit presented here is a differential amplifier intended to receive balanced line inputs in...

When it comes to recording audio in wildlife or nature, you require something with a small form factor that does not harm the environment. There are several wildlife species that produce noise in ultrasonic frequencies like bats, moths, etc. Here comes the name for the credit card-sized...

Virtual desktops are used extensively in the IT sector currently due to the COVID-19 pandemic. This set-up allows the employees to work remotely and is convenient. Virtual desktops are preconfigured images of operating systems and applications in which the desktop environment is...

This audio-balanced line driver project enables to drive hundreds of feet in length of cables without becoming unstable The project is based on the THAT1646 chip, which is a new generation monolithic differential line driver that offers improved performance over conventional...

Sometime in December last year, Raspberry Pi Foundation, after acquiring IQAudio Brand, mentioned that it had plans to relaunch IQAudio’s four most popular HATs as their official Pi accessories. The foundation has now reintroduced the popular audio add-ons with improved features and...
