The Sounds of Raspberry

Filed under

I've been talking about using Linux-based systems for embedded use lately. One very popular system has been the Raspberry Pi. I wanted to do a small project with the Pi, but was disappointed to see that it only has audio out and no audio in capabilities.

On the other hand, it does have USB ports. I rummaged a bit and found an old Labtec USB mic based on an AK5370 A/D converter. As expected, the Pi found it and suddenly had audio input capabilities.

There are many ways to work with audio hardware under Linux, but one of the best is the PortAudio library. One of the great things about this library is that is very portable to different platforms and it is also easy to use.

budgie-remix 16.04.2 Comes Equipped with the HWE Kernel from Ubuntu 16.04.2 LTS

The great folks from the Ubuntu Budgie (formerly budgie-remix) GNU/Linux distribution had the pleasure of announcing the general availability of budgie-remix 16.04.2. What's budgie-remix 16.04.2, you may wonder? Well, as Ubuntu Budgie did not yet have a stable release, and because many people are still using the distro on their PCs with its previous name (budgie-remix), the developers updated it to be based on the recently released Ubuntu 16.04.2 LTS (Xenial Xerus) operating system. Being based on Ubuntu 16.04.2 LTS, which inherits the newer Linux 4.8 kernel and an updated graphics stack based on Mesa 12.0 3D Graphics Library from Ubuntu 16.10 (Yakkety Yak), budgie-remix 16.04.2 comes equipped with its HWE kernel and graphics stack, as well as the latest Budgie 10.2.9 desktop environment.
