Drumstick Metronome ~ Linux Precision Beats


Drumstick Metronome is a MIDI based metronome using the ALSA sequencer. It’s intended for musicians and music students, as a tool to keep the rhythm while playing musical instruments. It uses MIDI for sound generation instead of digital audio, allowing low CPU usage and very accurate timing, thanks to the ALSA sequencer.

Features:

  • Easy to use graphic user interface.
  • MIDI only. Can be used with software or external MIDI synthesizers.
  • Based on ALSA sequencer. Provides input and output ports
  • Highly customizable parameters.
  • External control: D-Bus and MIDI realtime.
  • Custom rhythm patterns.

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.

Shairport Sync ~ Unix AirPlay Player


Shairport Sync is an AirPlay audio player – it plays audio streamed from iTunes, iOS, Apple TV and macOS devices and AirPlay sources such as Quicktime Player and ForkedDaapd, among others.

Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible for players that support it, such as iTunes and the macOS Music app.

Shairport Sync runs on Linux, FreeBSD and OpenBSD. It does not support AirPlay video or photo streaming.
