prestosynth

prestosynth is a presto* software synthesizer based on SoundFont specification.

*) presto[Italian]: as fast as you can

Motivation

As the rapid progress of symbolic music generation, there is a growing need of fast server-side audio rendering from symbolic music. I proposed prestosynth following these principles:

• For the environment of servers, it should be self-contained and portable.
• For the characteristic of servers, parallelism and multiplexing should be utilized extremly, while memory cost is negligible.
• For the simplicity, it should utilize out-of-the-box standards.

Limitation

• prestosynth is not intended to fulfill all of SoundFont specification but to provide synthesization in presto speed.
• prestosynth is not intended to be a real-time synthesizer but to extremly utilize parallelism.
• prestosynth will yield more memory than other synthsizers due to aggressive cache mechanism.
• Modulator of Soundfont Standard is not implemented yet, for its complex topology.
• MIDI Controller is not implemented yet.

Implemented

• Wavetable Oscillator
• Sample Looping
• Envelope Generator
• Gain Amplifier
• Low Pass Filter
• Conditioning volume with LFO, MOD
• Conditioning LPF with LFO, MOD

TODO

• Conditioning pitch bend with LFO, MOD
• Basic Reverb effect
• Basic Chrous effect
