WavPack ~ Hybrid Lossless Audio Compression


WavPack is a completely open audio compression format providing lossless, high-quality lossy, and a unique hybrid compression mode. For version 5.0.0, several new file formats and lossless DSD audio compression were added, making WavPack a universal audio archiving solution.

In the default lossless mode WavPack acts just like a WinZip compressor for audio files. However, unlike MP3 or WMA encoding which can affect the sound quality, not a single bit of the original information is lost, so there’s no chance of degradation. This makes lossless mode ideal for archiving audio material or any other situation where quality is paramount. The compression ratio depends on the source material, but generally is between 30% and 70%.

The hybrid mode provides all the advantages of lossless compression with an additional bonus. Instead of creating a single file, this mode creates both a relatively small, high-quality lossy file that can be used all by itself, and a “correction” file that (when combined with the lossy file) provides full lossless restoration. For some users this means never having to choose between lossless and lossy compression!

WavPack employs only well known, public domain techniques (i.e., linear prediction with LMS adaptation, Elias and Golomb codes) in its implementation. Methods and algorithms that have ever been patented (e.g., arithmetic coding, LZW compression) are specifically avoided. This ensures that WavPack encoders and decoders will remain open and royalty-free.

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.
