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!

Finds problems in MP3 files and helps the user to fix many of them using included tools. Looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3.) Also includes a tag editor and a file renamer.

displaysound chung is a small program to display the selected input sound port (for example the system input mixer of the computer , or the mic microphone ) data in a scope like or spectrum FFT fourier window. or midi keyboard. Is writtten in easy fast freebasic . Can record,playrec, saveasMP3, loadMP3 (added 01/2022) with automatic level record and autostart/stop rec max 20mn flat0=auto flat spectrum, flat1=auto clone spectrum, (4096 band equalizer exciter enhancer) usage example :...

mp3tomid chung is a realtime free polyphonic high quality mp3 audio to mid converter written in freebasic with fbsound. it converts mp3 files to polyphonic piano midi data sent to the choozen midi out port, connected for example to a midi recorder to produce midifiles , or to the onboard pc midi mapper for direct listening. works with Bill Evans's piano songs and Pat Metheny (others:to try).

Sonic Flow are C/C++ libraries for dataflow-oriented audio signal processing. Advanced features: feedback, multirate and hierarchical networks; signal processing block library. High-quality chorus/flanger, compressor/expander, param.EQ etc. example code.

CoRoPa stands for Computational Rough Paths. The aim of CoRoPa is to provide a software framework for various ideas related to Rough Path Theory, including rough differential equations and the digital description of serial data streams.

VibroToolbox is a tool for research and education in vibrometry. Test your audio equipment, describe responses to vibratory stimulation and analyze directionality. It works with precision i/o hardware or simple sound cards, various sensors and speakers.

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.

Introduction to DR14 T.meter DR14 T.meter is a free and opens source command line tool for computing the Dynamic Range of your music according to the procedure used in the off-line meter released by the Pleasurize Music Foundation. This tool is very useful to measure how is loud your music and for understanding that a good quality album always has also a good dynamic, and it's also useful for understanding the effects of the so called loudness war. Dr14 t.meter is released under the...

Onset detector for musical signals, with an emphasis on real-time onset detection for interactive music systems. Hence this aims to be a small, efficient, lightweight onset detection system that provides good-quality detection.

Annoyed by listening to music you already listened years ago? This command line utility sorts out new MP3s that you already have and reports the ones you like that are in a better quality.

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

The open source, multimodal interactive "Sensitive Artificial Listener" dialogue system created by the EU project SEMAINE.

DTMF detector library and/or application that reads in the specified audio file and returns/outputs whether DTMF detected and/or list of detected digits. May have GUI and command line interfaces.

The Audio-Analyzer project is a set of tools for measuring the frequency response, distortion, and quality of audio equipment. It includes test signal generators and spectrum analyzers.

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.

mp3stegz is an application that apply steganographic (steganography) algorithm in mp3 files. mp3stegz will maintain original mp3 file's size and sound quality. The hidden message is compressed(zlib) and encrypted(Rijndael).

This is a software library for measuring acoustic property with your sound card. It allows users to measure acoustic property without any expensive devices. This is useful for all acoustic engineers/resarchers/students.

Program performs bird species recognition by their voices. In early stage of development but working well with some popular species and good samples quality.

The CPU RightMark suite is meant for objective measurement of performance of modern and future processors in different computational tasks such as numerical modeling of physical processes and solving of 3D graphic problems.

This project is a Free Software implementation of reccomandation ITU-R.BS.1387 that provide to describe the algorithm of - Perceptual Evaluation of Audio Quality - (PEAQ).

mp3_check helps to identify in explicit detail MP3s that do not correctly follow the MP3 format. It also looks for invalid frame headers, missing frames, etc., and generates useful statistics. This can be useful when building a high-quality mp3 archive...
