Tomahawk ~ Metadata Based Player


Tomahawk is a free multi-source and cross-platform music player. An application that can play not only your local files, but also stream from services like Spotify, Beats, SoundCloud, Google Music, YouTube and many others. You can even connect with your friends’ Tomahawks, share your musical gems or listen along with them. Let the music play!

Tomahawk is basically a player for music metadata. At its core it decouples the metadata about a song from the source and reassembles it for each user based on their individual music accessibility and rights. In short, given the name of a song and artist, Tomahawk will find the right source, for the right user at the right time. This fundamentally different approach to music enables a range of new music consumption and sharing experiences previously not possible.

Music Sources:

  • Local music library (MP3, Ogg, FLAC and many other formats)
  • Networked music libraries (other connected computers)
Subscription Music Services
Free Streaming / Music Promotion Platforms
Network/Cloud storage

Third party-developed resolvers have also been written for services like YouTube, Qobuz and others. We’ve also heard of digital music distributors writing their own for their internal CMSes to help them navigate and preview their content. That’s cool.

tapedeck ~ DJ Audio Editor


Tapedeck is an audio editor for Linux with an alternative control interface. Instead of a mouse, keyboard, and screen, it uses the DJ board Hercules DJ Control Instinct, and a set of LED graph displays (not currently implemented, simulated with terminal graphics).

GXLame ~ Low-bitrate MP3 Encoder


GXLame is an MP3 encoder based off of LAME v3.98.4 and v3.99b0 which has been heavily optimized for high-quality, low-bitrate VBR encoding. It is similar in concept to other popular encoders at these bitrates such as some AAC codecs, Vorbis mods, and so forth at bitrates down to 56kbps. This codec does not rely on aggressive lowpassing or resampling to achieve these low bitrates, and the quality aims to be acceptable at much lower bitrates than have come to be expected of the standard.

Eisenkraut ~ Multi-channel Audio Editor


The audio file editor, baptised ‘Eisenkraut’, came into existence (as a scaffold) during a project class on audio programming in Java at the SeaM in Weimar. It is distinguished by a number of traits which makes it particularly interesting in the field of computer music: There are no restrictions with regard to the number of channels in a file, and there is an OSC interface via which the functionality can be extended, for example using the SuperCollider language. Possible applications of such extensions are the transfer of marker information or the maintenance of meta data for segmented files, the algorithmic editing (cut/copy/paste) of files, or the addition of your own sound transformations or special decoders (e.g. an MS matrix).

Wok Loudness ~ Dynamic Equalization


Wok Loudness simulates the loudness button on old HiFi amps, which alters the frequency response curve to correspond roughly with the equal loudness characteristic of the ear at lower volumes.

The level of high and low frequencies is increased at low listening levels, to compensate for the fact that as the volume of audio decreases, the ears lower sensitivity to extreme high and low frequencies may cause these signals to fall below threshold.  As a result audio material may seem to become ‘thin’ sounding at low volumes, losing bass and treble, the ‘Loudness compensation’ button (often just labelled ‘Loudness’ or ‘Loud’) is intended to rectify this situation.
