sndio ~ Unix Audio & MIDI Server


Sndio is a small audio and MIDI framework part of the OpenBSD project and ported to FreeBSD, Linux and NetBSD. It provides a lightweight audio & MIDI server and a fully documented user-space API to access either the server or the hardware directly in a uniform way. Sndio is designed to work for desktop applications, but pays special attention to synchronization mechanisms and reliability required by music applications. Reliability through simplicity are part of the project goals.

Elisa ~ Simple KDE Music Player


Elisa is a music player developed by the KDE community that strives to be simple and nice to use. We also recognize that we need a flexible product to account for the different workflows and use-cases of our users. We focus on a very good integration with the Plasma desktop of the KDE community without compromising the support for other platforms (other Linux desktop environments, Windows and Android). We are creating a reliable product that is a joy to use and respects our users privacy. As such, we will prefer to support online services where users are in control of their data.

FreqTweak ~ Spectral Manipulation & Display


FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.

It is an extremely addictive audio toy, but I hope it has value for serious audio work too (sound design, etc). The spectrum analysis is pretty useful in its own right.

wtfplay ~ Linux High Quality Sound


Wtfplay project is an initiative to create a quality music player for Linux. Ultimately the project has just one objective – deliver the best sound quality possible – with no compromises.

Initially the player has been created: wtfplay. Soon the project evolved and wtfplay-live Linux distribution was born.

wtfplay-live is a minimalist Linux distribution purely dedicated to audio playback. It does not have many features, but offers exceptional sound quality as a reward. Simply put: it is created to play music and it plays music well.

The main features of wtfplay-live are:

  • Memory based, bit perfect playback of WAV and FLAC files with PCM data (16 and 24 bit, up to 384kHz), and DSF files with DSD data.
  • Fully command line driven. No graphical mode. No network either. The whole system is optimised for sound playback from local disks.
  • A small text mode user interface: wtfcui – for more convenient usage.
  • Precisely tailored Linux kernel for best sound performance.
  • Distributed as Live CD: does not require installation on a hard disk, does not make any changes to your computer configuration.
  • Very small system size: the distribution ISO image is less than 50MB.
  • Good documentation – to give you all information that you need to comfortably listen to music.

The philosophy of wtfplay project is simple: provide the minimum set of features for easy use and focus 100% efforts on sound quality.
