LAME is an educational tool to be used for learning about MP3 encoding. The goal of the LAME project is to improve the psycho acoustics, quality and speed of MP3 encoding. Note: we provide source code only!

LSP (Linux Studio Plugins) is a collection of open-source plugins currently compatible with LADSPA, LV2 and LinuxVST formats. Standalone plugins for JACK are provided since version 1.0.8. Experimental support of ARMv7 added since version 1.1.4 Experimental support of AArch64 added since version 1.1.9 Decomposition of modules and new UI introduced in 1.2.0 Added CLAP support in 1.2.5 Added VST3 support in 1.2.15 The basic idea is to fill the lack of good and useful plugins under the...

TAPClean is a Commodore tape preservation / restoration tool. It will check, repair, and remaster Commodore 64 and VIC 20 TAP or DC2N DMP files (tape images).

Loris is a library for sound analysis, synthesis, and morphing, developed by Kelly Fitz and Lippold Haken at the CERL Sound Group. Loris includes a C++ class library, Python module, C-linkable interface, command line utilities, and documentation.

Reads audio from Windows audio interface or wave file and creates a continuous spectrum display. Command line support for generating sine, square, triangle and sawtooth wave files. Uses biquad IIR digital filters for frequency detection, plus digital lowpass filters for output extraction. Highly configurable. 60+ FPS with suitable hardware. Manual or automatic gain control.

DRC generates digital room correction FIR filters to be used within HiFi systems in conjunction with real time convolution engines like BruteFIR.

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.

ManyEars implements real-time microphone array processing to perform sound source localisation, tracking and separation. It was designed for mobile robot audition in dynamic environments. NOTE: Development will continue on github : https://github.com/introlab/manyears

Quickplot is a fast interactive 2D plotter with infinite zooming, value picking, pipe input, and unlimited plots displayed. Quickplot is meant for looking at your data quickly and of secondary importance is making static pictures of your data.

Simpl is an open source library for sinusoidal modelling written in the Python programming language and making use of SciPy.

A cross platform dual channel FFT based Acoustic Analysis Tool to help engineers analyze live professional sound systems using the transfer function. One feature is the ability to capture four sample plots, average them, and invert to aid in final EQ

Zwicker's Loudness Calculation (ISO532B) Tools. The project includes a loudness calculation program based on Zwicker's Method, and a WAV file analyzer generating data files for loudness calculation. Documentation and test files are also provided.

1.) Investigation with cosine transform, and anti transform algorithm, with some voice recognition code. 2.) Translator: Croatian, English. 3.) 2D to 3D picture algorithm (principle) and new 2Dto3D video conversion code with AviSynth video scripting

Transana is a cross-platform tool for the transcription and qualitative analysis of audio and video data. It also provides the ability to identify and organize analytically interesting portions of videos, as well as attach keywords to those video clips.

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.

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.

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.

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.

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.

Humdrum Toolkit for music research

STASS stands for Sound Treatment, Analysis and Synthesis Software. It will provide ingeneers and searchers easy-to-use as well as performant tools for sound analysis (spectro, sona and so on), treatment (filters, noise-gate) and synthesis (scepstrum).

Sonogram and waveform display programm for Unix using different algorithms like FFT and LPC to display musical features or potential artefacts that you may no be able to hear. Superimposed tuneable Staff-Lines allow for easy transcription of music.

A modular audio programming language, designed to write applications quickly. Its main goal is real time audio processing, but it should be used for any kind of development.

Sound Orgy is a suite of command line tools for the purpose of sound production and modification as well other misc sound related functons. Sound Orgy consists of components which use command line piping to connect to each other much like patch cords.

SAA (SSPLab Audio Analyzer) It will be able to separate sources, recognize speech and analyze the auditory scene. It can also synthesize spatialised sounds from mono recording, edit, analyze via spectrogram, filter and re-sample signals.
