FMS is basically a tool to generate all kinds of sounds. It should work on any up-to-date Linux system.

Up to this day, the following features are implemented:


Playing sounds

• with any frequency and volume
  
• one after another or at the same time (mixer) or both
  
• stereo (different sounds on different channels)
  
• with any balance between the two channels
  
• with built-in sweep that even follows frequency modulation
  
• like speech synthesis
  
• both on-the-fly playing with direct user access and asynchronous, pre-computed output; also combining the two, taking the
  best of both
  
• with all modulation options described below
  

Making noise

• now although it tends to get noisy in any way, we mean real noise here
  
• in 4 different ways
  
• nearly-white noise
  
• narrow band noise
  

Modulating

• amplitude (volume)
  
• frequency
  
• minima, maxima, amplitude and frequency of the modulation (here the "Fully Modular" comes to existence)
  
• balance, moving the sound from left to right and back in stereo mode
  
• narrowness of the noise frequency band in many different ways
  

Making music

• some-kind-of-midi-mapping mode (sound + envelope => instrument, FMS midi file format)
  
• auto-converter and player for MUS file format,
  
• auto-composer for those who like a rather modern kind of music
  
• chords
  

Displaying

• spectrum of a sound
  
• oscillogram of a sound
  
• mixes between different sounds with different volumes / frequencies
  

Saving

• sounds as oscillograms in FMS file format (mathematical description, not complete wavetables)
  
• sounds as Fourier overtone amplitudes
  
• music in FMS midi format
  
• FMS output in wave format
  
• wave file sounds in FMS file format (auto-converter) - experimental
  

GUI

• a somewhat ugly and extremely limited tcl/tk gui
  
• FROCOR, an installation that connects the FMS sound backend to graphical interfaces and outputs
  
• a fully modular Qt GUI - experimental,
