Enhance your Raspberry Pi with Audio

Raspberry Pi single-board computers have been used in a wide variety of ways, but one of the most exciting applications is as a media server. Inexpensive and compact, a Raspberry Pi can output both video and audio signals out-of-the-box, but if you want to be able to power speakers (beyond small headphone units) directly, you’ll need a bit more hardware.

Let’s face it, we love our Raspberry Pi but audio quality is just bad or inexistant on the Pi. Audio Codec HAT enables your Raspberry Pi 4 ( Pi 3, 2, B+, A+, Zero and Zero 2 W) with a state of the art audio codec at a reasonable price. Great for home audio sound sytem, internet radio, or any project with audio at a price that makes sense.

The Audio Codec HAT is a low-power, high-quality stereo CODEC for portable digital audio applications, based on the WM8960 IC, which has minimal leakage, great PSRR, and pop/click suppression mechanisms, and allows direct battery connection to the speaker supply. Speaker output power may be enhanced while other analogue supply currents are minimised thanks to the flexible speaker boost settings.

Audio Codec HAT Specifications:

• Raspberry Pi 40PIN GPIO Extension Header, which is compatible with the Raspberry Pi line of boards.
• The WM8960 low-power stereo CODEC is integrated, and it communicates through the I2S interface.
• Dual high-quality MEMS silicon microphones are included, as well as capability for left and right double channel recording and good sound quality.
• External earphones can be used to play music using the onboard standard 3.5mm headphone connector.
• Speakers are driven directly via an onboard dual-channel speaker interface.
• Supports stereo, 3D surround sound, and other sound effects.

This is a Raspberry Pi sound card HAT with low power consumption, stereo encoding / decoding, Hi-Fi playing / recording, and the ability to directly drive speakers to play music.

So that’s the amazing audio card for the Raspbery Pi I found.

Enjoy your amzing sound with Audio Codec HAT!
