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.
This software generates a distorted version of an audio file that can give a required audio quality. This is for use with subjective tests, such as MUSHRA, where an anchor is required of a particular quality.
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.
Pixapr is a visualization plugin for XMMS, but not regular visualization plugin. It will output REAL light show by devices controlled via parallel port. It is based on XPLSISNJASP and Palace. Pixapr stands for Pixapr Is Xplsisnjasp And Palace Reloaded.
The Analysis & Resynthesis Sound Spectrograph analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.
This project involves providing library support to read and write riff files.
Functions such as readRiff and writeRiff are included in the shared library.
eXtace is a 3D audio visualization tool (or eye candy depending on how you look at it). eXtace requires ESD (Esound) for its sound input source. It performs a FFT (fast fourier transform) on audio and displays it via various graphical modes.
The Analysis & Reconstruction Sound Engine analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.
Easy-to-use platform-independent plugin API for the extraction of low-level features from audio data in PCM format, as required in the context of music information retrieval software.
Use cicsWave to extract digital audio data from wav files. 16 & 24 bit stereo formats at any sample rate is supported. A csv (comma separated values) file is created which can be used in spreadsheets etc. Only 32000 samples (both) channels are extracted.
BpmDj: Free DJ tools contains an automatic & accurate BPM counter. Determines sound color, rythm & echo. The player provides measurejumps, persistent cue's and beatgraphs. The program requires multiple dsp's or computers. http://bpmdj.yellowcouch.org/
This is a simple C library for working with the raw data in uncompressed WAV files. There are many better libraries for dealing with WAV files than this one. I wrote this to do some experimenting, and it's probably not the solution you're looking for.
RateIt is a GUI tool for performing subjective testing of audio samples based on the MUltiple Stimuli with Hidden Reference and Anchor (MUSHRA) methodology as specified in ITU-R recommendation BS.1534-1.
OpenTranscribe is a software to aid musicians in transcribing music. It lets you slow down a part of the music without affecting pitch. It also lets you loop over a section which have some tricky parts.
FFT Spectra is a tool for visualization of frequency spectra of an audio signal. What is it good for? For instance, you can verify whether you are able to sing and whistle in-tune or tune your guitar.
A set of plugins for the DSSI synth plugin architecture with GTK-based GUIs, all written in C and C++ using liblo and libglademm. Plugins will include an oscillator, an envelope generator, and a step sequencer.
RECWAV gives a processor-efficient display of the spectrograph of an audio file, showing the energy in the sound at each moment and frequency. It was originally developed on a '286 under DOS and now also runs under Linux with svgalib.
