Open Source ChromeOS Audio Analysis Software

MP3Gain analyzes and losslessly adjusts mp3 files to a specified target volume. It does not simply do peak amplitude normalization. Instead, it performs statistical analysis to determine how loud the file actually sounds to the human ear.

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.

getID3() is a PHP script that extracts useful information (such as ID3 tags, bitrate, playtime, etc.) from MP3s & other multimedia file formats (Ogg, WMA, WMV, ASF, WAV, AVI, AAC, VQF, FLAC, MusePack, Real, QuickTime, Monkey's Audio, MIDI and more).

SPTK is a suite of speech signal processing tools for UNIX environments, e.g., LPC analysis, PARCOR analysis, LSP analysis, PARCOR synthesis filter, LSP synthesis filter, vector quantization techniques, and other extended versions of them.

jMIR is an open-source software suite implemented in Java for use in music information retrieval (MIR) research. It can be used to study music in the form of audio recordings, symbolic encodings and lyrical transcriptions, and can also mine cultural information from the Internet. It also includes tools for managing and profiling large music collections and for checking audio for production errors. jMIR includes software for extracting features, applying machine learning algorithms, applying heuristic error error checkers, mining metadata and analyzing metadata.

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

MPC Maid ("MM") is a software editor for the Akai MPC 500, MPC 1000, and MPC 2500. It is Mac, PC, and Linux-compliant and makes the edition of MPC programs files easy. It also features a semi-automatic slicing tool to chop loops into slices.

mp3guessenc is based upon the original project by Naoki Shibata. This command line utility was born to detect the encoder used for a mpeg layer III file but now it can do more and scan any mpeg audio file (any layer) and print a LOT of useful information. Latest modifications include fixes, new features and code optimizations.

Both the Midas M32 and Behringer X32 share the same design of show management using the console GUI, M32-Edit and X32-Edit apps. This app provides an alternative method to manage these show files (cues, scenes and snippets). It provides an easier method of reorganizing and importing/exporting of files.

LAoE is a rich featured graphical audiosample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many plugins suitable to manipulate sound, such as filtering, retouching, resampling...

The Analysis & Resynthesis Sound Spectrograph analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

eyeD3 is a Python module that provides the ability to read ID3 tags (v1 and v2), and MP3 headers (bit rate, sample frequency, play time).

MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition along with sample applications (identification, NLP, etc.) of its use, implemented in Java.

NOTE: Project is looking for a new maintainer MPEG Maaate is a platform to do compressed-domain analysis of mpeg audio files (mpeg-1 layers 1,2,3), which includes mp3 files. The library has a bunch of filters which are implemented as plugins, such as histogram, pauseRate, signalMagnitude etc. (last successful compile was probably round 2005)

PsySoundPro - audio file analysis for objective psychoacoustics measures. Includes measures like Virtual Pitch, Loudness, Etc. etc.

jAudio is a project implementing a number of common feature extraction algorithms for analyzing audio in java. Output is either in Weka's ARFF format or the ACE format. Can be used either as a GUI application, command-line application, or embedded. The primary repository is on github (dmcennis) which pushes to this projects github repository.

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.

Instrument tuner. It can help you to tune a piano, a guitar ... Accordeur displays spectrum and calculates the pitch really played. A visual bar allows an easy tuning. Instruments and temperaments are customizable.

This perl-script takes a midi-file as input and tries to determine chords, without the need of a graphical-user-interface (GUI).

Reads and writes ID3 tags v1 and v2 from MP3 files.

A visualization of the fourier transform applied to sound data. Analyzes a time-domain sound sample using the Fourier Transform, and graphically displays the results and sound in real time. Attempts to audio into sheet music.

The Analysis & Reconstruction Sound Engine analyses a sound file into a spectrogram and is able to synthesise this spectrogram, or any other user-created image, back into a sound.

Apoplexy provides simple, fast and direct MP3 management. Allows batch entry of track information (artist, album, track, playlist) and configurable sorting and archival of files. Crafted in finest perl and utilizing the wxPerl crossplatform GUI toolkit,

can be used to restore skipping and jumping or scratched audio CD. Needs to copy tracks multiple times and then using this tool fix broken parts on wav files.
