Polymeter ~ Compose Polymeter Based Music


Polymeter is a MIDI sequencer for music that’s in multiple prime meters (1, 2, 3, 5, 7, 11, etc.) simultaneously. Each track has its own loop length, and when the lengths differ, the tracks “slip” (or shift phase) relative to each other. The resulting interference pattern is sufficiently intricate that variations similar to the embellishments of a live performer can be generated algorithmically.

Features:

  • Multitrack step sequencer for polymeter
  • Each track has its own loop length
  • Any number of tracks, of any length
  • Full clipboard support (copy/cut/paste)
  • Unlimited undo and redo for all edits
  • Multiple tracks can be edited at once
  • Optionally shows current position within each track
  • Drag reordering of tracks
  • Exports a MIDI file
  • Join adjacent steps to make tied notes
  • Velocity editing
  • Controller tracks
  • Recording of live arrangement
  • Editing of arrangement on timeline
  • Inter-track modulation of mute, note, velocity, duration, position, and more
  • Live performance view with full screen mode
  • Recursive modulation (modulation of modulation) for mute and position
  • Modulation graphing via Graphviz
  • MIDI mapping of all parameters with learn mode
  • Optionally transmits MIDI clock

TspCheck ~ Loudspeaker Thiele / Small Paramaters


As the program name suggests, TspCheck is a program that checks whether the determined or specified TS parameters of a loudspeaker match. Often you can then find out, for example, that the efficiency has been rounded up a bit too benevolently, or you can estimate the membrane mass, the resilience of the restraint, etc. by cleverly combining the information available.

In addition, the following is determined:

  • Max. Lin. SPL @ 50 Hz in CB – the maximum sound pressure that can be achieved in a closed housing at 50 Hz using the maximum linear stroke
  • SPL_m = SPL_e – the frequency from which the maximum achievable sound pressure at full input power is stroke limited.

BallroomDJ ~ Ballroom Audio Player


BallroomDJ is a ballroom music player. It is designed to be able to play music the entire evening without intervention. Use for your personal training, dance studio, and ballroom, dancesport, Argentine tango, country western, or west coast swing events.

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).
