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).

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

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.

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.

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.

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.

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...

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.

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.

Audio a Midi bajo octave. Solo soporta wav, pero pretendo que acepte otros. Quiero prepararlo para polifonía. <p>Audio to Midi converter, under octave, it only supports wav, but I pretend it to accept another files. I want to improve it to polyphonic.

Application which detects musical notes from the microphone. It allows listening to the microphone and play the detected notes to output (in midi). Multilanguage support. Zoom Dark mode option JDK-17 compatibility With v1.2 it includes a pitch shifter (making voice lower or sharper through a slider) There is a demo video which shows how it works (the demo video can be visited from Help menu of the application) You can also see the pitch-shifter demo version here: https://frojasg1.com:8443/resource_counter/resourceCounter?operation=countAndForward&url=https%3A%2F%2Ffrojasg1.com%2Fdemos%2Faplicaciones%2FInstrumentalMusic%2Fpitch.shifter.mp4%3Forigin%3Dsourceforge&origin=web You can find more about it at this web site: https://www.frojasg1.com:8443/downloads_web/web/html/instrumentalMusic.html?origin=sourceforge

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)

Rubato Composer is a music software based on the concepts and models of mathematical music theory and equally suited for music composition, analysis, performance, and logical or geometric operations.

NATSpectrum is a skinnable Spectrum Analyzer, Guitar Tuner, and Quick Volume Control. NS visualization mimics WinAMP 2.x style. NS is written in pure Win32 C++ and uses DirectDraw and DirectSound. (FFT, Frequency, Mixer, Microphone, DirectX, PNG, Record)

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).

baptools - broadcast audio production tools

Drum Count is a simple tool which analyzes sound in real-time to measure the number of strokes played on a drumset.

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.

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.

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.

With un# you get rid of duplicates in your media file archive. You also can edit extended informations and standardize them throug regular expressions.

DuMP3 is a duplicate and similar file finder. It finds exact duplicate binaries by hash, similar text files by substring content, images (JPG, BMP, GIF, PNG, etc) by color and audio files (MP3, WAV, OGG, etc) by wave data. Future: fonts, video.
