Audiomentations
A Python library for audio data augmentation
A Python library for audio data augmentation. Inspired by albumentations. Useful for deep learning. Runs on CPU. Supports mono audio and multichannel audio. Can be integrated in training pipelines in e.g. Tensorflow/Keras or Pytorch. Has helped people get world-class results in Kaggle competitions. Is used by companies making next-generation audio products. Mix in another sound, e.g. a background noise. Useful if your original sound is clean and you want to simulate an environment where... -

EarQuiz Frequencies
Software for technical ear training on equalization
...The overall training process involves ongoing learning and testing yourself. In the Learn mode, you listen to the pink noise or music (or other external audio) excerpts with switched off and on 1-octave or 1/3-octave graphic EQ, boosting or cutting frequency bands within certain spectral ranges. Then in the Test mode you are given a sequence of 10 similar examples, where you try to guess, which frequencies are boosted or cut, and you get scored. The program is Free Software, distributed under GNU GPL v3 License. -

byzorgan
Specialized sound synthesizer with Byzantine Church music scales
...On the screen there are labels with symbols of Byzantine notes. There is a metronome. The program is oriented on the Chrysanthos tuning of the diatonic scale: 9/8 - 12/11 - 88/81. The octave is divided into 17 (or 19) non-equal parts, it allows you to get all the Byzantine modes. -

SOFA Toolbox
Spatially Oriented Format for Acoustics
This project provided the SOFA Toolbox, a toolbox for the spatially oriented format for acoustics (SOFA). The SOFA Toolbox is the successor of the SOFA API for Matlab/Octave. More information about SOFA can be found here: http://sofaconventions.org On July 2025, we have left SourceForge: The SOFA Toolbox 2.2.0 is the last release published here. All further releases can be found at the SONICOM Ecosystem: https://ecosystem.sonicom.eu/tools/ The code development happens on GitHub: https://github.com/sofacoustics/SOFAtoolbox If you'd like to contact us, contact us via https://www.oeaw.ac.at/en/ari/team/our-team. ... -

Ultimate Mono2Stereo
A better mono to stereo audio conversion tool
...All this is accomplished by using the ffmpeg crossover audio filter to split the sound into 8 frequency bands. The split points are based on center frequencies of a typical 1/3 octave equalizer. Those 8 bands are then panned in varying degrees to left and right. The varying width of each band is set to achieve the best balance between the left and right channels. Mind you: the goal was not to exactly replicate orchestral seating. It was to best alleviate that "tin can in a hole in the wall" mono sound. -

Audovia
Database application for making music using JFugue MusicStrings
...Songs can be developed, tested and edited very quickly and easily by virtue of the database structure and the JFugue MusicString notation. Notes within a MusicString are specified by their name and octave or by their MIDI value and their durations are specified either by character code, or numerically. You can use notes from C0 to G10, corresponding to MIDI values 0 to 127. Middle C is C5. Songs can be exported to MIDI or WAV for music processing or publishing. Please visit the Audovia website for more information: https://songbase.github.io/ -

GTK+ IOStream
GTK+iostream, Data plots, ORB, Neural Networks, WSOLA
Create GTK+ interfaces using IOStream style code. Its simple and quick! Also providing simple data plotting (similar to Matlab/Octave), ORB (Object Request Broker), and Neural Network computations. You can create GTK+ GUIs in a few lines of code. Labels<<"Thanks for reading"; (HBox<<Labels).show(); or even one line : (HBox() << (Labels()<<"Thanks for reading")).show(); Inline code destructs the classes, but leaves the widgets/callbacks operating. -

Virtual Sound Level Meter
Virtual Sound Level Meter for analyzing calibrated sound files
...The program will read in a calibrated .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter. The software implements Fast, Slow, Impulse and LEQ; A, C and Flat Weighting; Ln and Noise Dose analysis; Octave and 1/3 Octave band analysis; high resolution FFT analysis and spectrograms. Band analysis can be made using fast FFT methods or slower, but ANSI standard methods. Source code requires MATLAB + Signal Processing Toolbox. Developed under MATLAB R2010a (but might work with some earlier versions) Executable version does not require MATLAB and runs under Windows XP, Vista, and Windows 7. -
