Audio spectrum visualiser in 3D for Linux
Spectrum3d is a software for Linux that displays the harmonics of the sound in 3D, either in real-time or from a preloaded file. It is multitouch and compatible with JACK. It uses OpenGL, SDL, Gstreamer, Gtk+ and (optionally) libjack.
A free multi-track audio editor and recorder
Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. The interface is translated into many languages. The version currently hosted here is 2.1.0 (March 2015). More recent versions than this are available from http://www.audacityteam.org/download/ . Audacity is free software, developed by a group of volunteers and distributed under the GNU General Public License (GPL). Programs like Audacity are also called open source software, because their source code is available for anyone to study or use. There are thousands of other free and open source programs, including the Firefox web browser, the LibreOffice or Apache OpenOffice office suites and entire Linux-based operating systems such as Ubuntu
DRC generates digital room correction FIR filters to be used within HiFi systems in conjunction with real time convolution engines like BruteFIR.
Spectral Analysis and Synthesis of Sounds
This project provides two binaries, mostly identical in features: a command line application (using libpopt for option parsing), and a graphical application (using libgtkmm (version 2) for the GUI and libao for sound playing). It uses spectral modelling techniques for parameterized sound analysis and synthesis. For the analysis phase an STFT is done (using libfftw for doing FFTs), and then harmonic/sinusoidal analysis. For the synthesis phase additive synthesis is used. Using libsndfile for sound loading and saving allows to support many uncompressed sound file formats (WAV, AIFF, AU, headerless RAW, ...), and also OGG and FLAC, but MP3 isn't supported. Available parameters include window type, size, and overlapping; sinusoid discarding; equalization; time strechting, frequency scaling and shifting; frequency and amplitude interpolation; normalization; dynamic range compression and expansion, etc. It can be used to obtain new sounds, from existing sound files.
This is a Java Just Intonation Calculator. It allows users on many platforms to calculate and hear just tunings. It will support saving and opening tunigs and opening spreadsheet documents and allow users to send tunings to their synthesizers, via MIDI
SoundRuler is a tool for acoustic analysis, graphing and teaching. It interactively recognizes and measures 35 temporal and spectral properties of each sound in a file. It also features several measurement, graphing and didactic modules.
Digital vinyl sound reconstruction.
Visore is a software project for the sound restoration of vinyl (gramophone) records. Visore filters the noise caused by scratches, dust and degradation and amplifies the sound where necessary.
