Music research software
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.
A C++ library and Python module for audio synthesis featuring dynamic digital filters. Nsound lets you easily shape waveforms and write to disk or plot them. Nsound aims to be as powerful as Csound but easy to use.

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.
VLevel is a dynamic compressor which amplifies the quiet parts of music. It uses a look-ahead buffer, so the changes are gradual and the audio never clips. It is a command line filter and a LADSPA plugin, so it works with XMMS.
SoundRuler is a tool for acoustic analysis, graphing and teaching. It interactively recognizes and measures 35 temporal and spectral properties of each sound in a file. It also features several measurement, graphing and didactic modules.

DuMP3 is a duplicate and similar file finder.
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.
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.
This program removes clicks, pops and bitrots from audio files
There is a one common problem in capturing audio from old vinyl disks. Many of the disks have scratches that impose needles to make little jumps producing short sharp noises named 'click'. My project's aim was to create a free software which able to remove this kind of noise from audio files produced by capturing vinyl disk. Also the application is able to remove some other kinds of short sharp noises like 'bitrots'. The program can detect start positions and lengths of clicks and replaces the damaged samples with interpolated ones automatically. Win 10 users can add the app from Wondows Store.
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.
FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain with a highly interactive GUI to manipulate and display the spectral data.
Transana is a cross-platform tool for the transcription and qualitative analysis of audio and video data. It also provides the ability to identify and organize analytically interesting portions of videos, as well as attach keywords to those video clips.
