This board will take your Pi audio project to a whole new level!

Posted on Posted in Tech Feeds

Music enriches our daily life and if you love to listen to music, then you do want a good sound system. As a developer working with Pi, you have worked with the audio port but it doesn’t fulfill your expectation. Then come and meet the pisound that will bring your audio projects to a whole new level!

pisound is an ultra-low latency high-quality soundcard and MIDI interface specially designed for Raspberry Pi. It is equipped with 192 kHz 24-bit Stereo Input and Output driven by Burr-Brown chips, DIN-5 MIDI Input and Output ports, user-customizable button and bundled software tools.

pisound allows you to connect a huge variety of different types of audio-related gear, ranging from your bass guitar to a CD player or your modular synth. Using Stereo Output you can hook pisound to any mixer, speakers or just plug in your headphones. For MIDI connectivity you also have a lot of options – MIDI In/Out through onboard DIN-5 sockets, USB-MIDI via Pi’s USB ports or even WiFi-MIDI!

Using pisound, you can turn your Raspberry Pi into a music instrument or effect, audiophile network player, portable recording studio, internet radio station or anything you can think of as long as it is audio related!

pisound works great with Raspbian, ArchLinux, Pixel, Ubuntu Mate, Audacity, Pure Data, Sonic Pi, SuperCollider, Volumio and any other Linux software!

Hardware Setup

Mount pisound on top of your Raspberry Pi via the 40-pin header and fasten it with the screws provided while the RPi is unpowered, so it appears as in the image at the top. Following are the compatible Pi models for pisound.

  • Raspberry Pi 1 Model A+
  • Raspberry Pi 1 Model B+
  • Raspberry Pi 2
  • Raspberry Pi 2 version 1.2
  • Raspberry Pi 3
  • Raspberry Pi Zero version 1.2
  • Raspberry Pi Zero version 1.3

Driver Setup

If you don’t have any Linux OS running on your Raspberry Pi, then start with Raspbian.

Power your Raspberry Pi up and install the driver by running the below commands in a terminal window:

wget -O
chmod +x

A couple of simple [Y/n] questions will be presented about whether to install some of the additional software to get you started faster and whether to set pisound as the default card.

For details, have a look in their doc section:

After driver installation process is complete, reboot your Raspberry Pi (if the script asked for it at the end) and that’s it. Now you can choose pisound as your main sound card through native Volume widget and use it with any Linux Audio/MIDI software. Done!

Spread it!
