Nuvola (Linux) Apps are web apps running in Nuvola Apps Runtime that provides them with more native user experience and richer desktop integration features than standard web browsers can offer. Nuvola specializes in music streaming services and offers background playback, handling of media key, integration with media player applets, Last.fm scrobbling, lyrics fetching, and much more.
Although Nuvola should work in all Linux desktop environments, we currently test only GNOME (Ubuntu, Fedora), Unity (Ubuntu), and Pantheon (elementaryOS). We hope to explore other desktops in the future.

Volumio ~ Headless Audiophile Player
Volumio is an headless audiophile music player, designed to play music with the highest possible fidelity. Volumio runs on most embedded devices (Raspberry Pi, UDOO, Odroid, Cubieboard, Beaglebone, Pine64, Allo Sparky…) and on any ordinary PC (x86).
Volumio is a free and open source Linux distribution, designed and fine-tuned exclusively for music playback. It runs on a variety of devices, typically small and inexpensive computers like the Raspberry PI, but also on low power PCs, notebooks or thin clients.
By flashing (installing) Volumio on any of these platforms, it will then become an headless audiophile music player. Headless means that the only way to control it will be with another mobile phone, computer or tablet.
This is made possible by Volumio’s User Interface: a web applications that runs on any device with a browser, and that allows for an easy and intuitive control of your playback sessions. All communications between the web app and Volumio will happen through your home network.
CDex ~ Digital Audio CD Extractor

Many other encoders are supported.

This is the synthesizer plug-in Surge which Claes Johanson (@kurasu) previously sold as a commercial product via the company vember audio.

It was originally released in 2005, and was one of Claes’ first larger projects. It is reliable and sounds great.
