Open Source Audio Analysis Software

Audacity is a free, easy-to-use, multi-track audio editor and recorder for Windows, Mac OS X, GNU/Linux and other operating systems. 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

MediaInfo is a convenient unified display of the most relevant technical and tag data for video and audio files.

Fast batch audio processor for automatic loudness adjustment and audio files splitting. The software automatically normalizes a batch of files to a given RMS volume, and can split tracks in several ones by detecting low level ("noise") chunks. It embeds : - a multi-band limiter, - an Automatic Gain Control, - an automated 10 bands equalizer, - a classic 3 bands semi-parametric equalizer, - a noise gate, - a trimming function, - user preset management.

This project will try to develop an audio analyser which displays several informations as phase in 2 ways (1 dimensional and 2 dimensional), waves shapes, spectrogram in full range and by 1/3 octavia with the value of the current peak frequency, and meter

AudiooPy stands for "Audio Manager in Python Object-Oriented Programming." This library provides a range of useful operations for sound files and audio fragments. It processes audio at the frame level, working with signed integer samples of 8, 16, or 32 bits, stored in byte-like objects. Key features include: - Reading and writing WAV files using Python's standard library. - A scientifically validated method for automatically detecting sound segments in speech. - Manipulation of raw audio data. - Audio mixing capabilities. - Automated computation of statistical descriptors for audio data. - Channel extraction. - Channel mixing. AudiooPy is entirely self-contained and does not rely on any external libraries. <https://img.shields.io/pypi/v/AudiooPy>

Thérémine is an audio program which reads realtime pitch and volume data from an USB Arduino Theremin, and generates high quality audio signal emulating a realistic instrument. It was originally designed to work with an Open.Theremin.UNO shield (see http://www.gaudi.ch/OpenTheremin), although it should work with other Arduino devices as long as you provide an appropriate program. Thérémine can play a variety of different tones. It comes with another program, Loop bank manager, whose purpose is to extract stationnary, looping samples from recorded wave files. It allows importing new instrumental tones into Thérémine, as long as the source recording contains reasonable data. Two demo sample banks are provided with Thérémine featuring violin and voice tones. Both were made using Loop bank manager.
