Tune is a note/chord detecting program for use with guitars, pianos, or voices. It uses an FFT to analyze incoming sound and computes the root frequency.
This is a program to store data calculated from the tempo of a song into different degrees of seconds for use with "programming synths". Written in C++ with Visual C++ Express. Java version coming soon.
Instrument tuner. It can help you to tune a piano, a guitar ... Accordeur displays spectrum and calculates the pitch really played. A visual bar allows an easy tuning. Instruments and temperaments are customizable.
AppSignal's MCP server hands Claude, Cursor, or Zed your real errors, traces, and the deploy that shipped them. AI writes the fix; you review the diff.
BeamformIt is an acoustic beamforming tool that accepts a variable amount of input channels and computes an output via a filter&sum beamforming technique. It can process all sorts of data acoustic files, leading to an homogeneous single output.
Mutelesser is an audio silence detection tool, for broadcast radio stations. Mutelesser detects lack of audio for a certain amount of time, and triggers actions that inform technical staff or start a backup play list, until audio source is restored.
FreqTweak is a tool for FFT-based realtime audio spectral manipulation and
display. It provides several algorithms for processing audio data in
the frequency domain with a highly interactive GUI to manipulate and
display the spectral data.
IcePick is the real guitar hero. IcePick aspires to be the open source alternative to Guitar Rising or Little Big Star. It presents the guitar player with an animated tab and rates their playback in realtime.
A collection of scripts and programs to automatically annotate video/audio for subtitles. Basically relies on a MARSYAS (Music Analysis, Retrieval and Synthesis for Audio Signals) plug-in for detecting human voice in polyphonic recordings.
This software is a music tutor: it helps you learning to play an instrument. It guesses the score you are playing, and measures your precision at the task, thus allowing you to improve. It also lets people playing in versus mode.
Katmus is an application for manual music transcription. It features a score editor synchronized with a wave file, time stretching, project manager and lots of other features.
MidiWriter is a framework for creating and composing music based on algorithms. The project includes already several examples using these technics. The output of MidiWriter is in the midi-format.
