3D Effect Audio Processor

The project presented here is a 3D sound processor, that regenerates 3D sound to stereo speakers. The board is able to regenerate 3D sound from a stereo audio input. It features of wide operating voltage range, wide dynamic range, and low output noise and is suitable for any audio application. This tiny module can add 3D sound effects to your next project. Basically, this mini low-cost module converts a stereo audio signal into 3D effect audio and it is based on PT2387 chip. The chip features a specially designed PTC HRTFs filter and with its space-enhanced circuit, it provides excellent audio quality and performance. The module provides excellent 3D effect audio output from a stereo audio source and a built-in LED display when the 3D sound effect is active. A tactile switch is provided to activate the 3D sound effect.
