The Sound Description Interchange Format (SDIF) is an established standard for the interchange of sound descriptions and analysis data. This project provides libraries, SDIF (in C) and Easdif (in C++), tools, and wrappers to read and write SDIF files.
Bitfake was originally created to detect fake .FLAC files through spectral analysis. It has since grown into a multipurpose CLI tool for handling music more easily and efficiently.
One common problem was that getting a track’s metadata required long ffprobe commands with messy output. Converting music with ffmpeg was also repetitive. The command itself is easy to remember, but writing scripts to convert entire directories felt inefficient and slow. This project now performs metadata and conversion tasks directly through linked libraries (TagLib/libsndfile/libav*).
Features:
Get metadata
Get ReplayGain info (useful for music players)
Spectral analysis on 44.1 kHz .FLAC files (higher sample rates may be misrepresented, so be careful)
Lossy diagnosis (banding score)
File Conversion + VBR Support (Works for outputs like .wav, .flac, .ogg, .mp3, .aac, .opus)
Tagging metadata (Works for single files, but not directories yet)
Calculating ReplayGain and applying it to files (Works for track replay gain iterating through directories, album replay gain is a bit funky?)
Directory Conversion (works for all previously mentioned formats!)
CoverArt+ (Brings along cover art among all conversions!)
Organizing Files by album! (Give a dir of random music, and bitfake will organize it – ty to uncognic)
Directory Tagging (YAY!)
Album folder renaming from tags (Artist – Album (Year))
DISTORT was conceived as a tool to allow one to apply a combination of complex distortions to any recorded signal, including music and hi-res recordings. DISTORT also provides simple visualization tools to examine the effects of all the distortions as they are being adjusted. The distorted sound file can be played through the available audio device drivers, from ASIO to WASAPI to Direct Sound.
The following distortions are currently provided with a variety of settings and options:
Harmonic distortion (THD, SINAD, THD+N)
Different noise floors and various spurious noise components, such as mains frequency
Various types of jitter, random, correlated, 1/f noise, and at various frequencies
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.

Audio Wizard (foo_audio_wizard) is a fiery chapter of The Wizardium, granting foobar2000 audiophiles and engineers tools for full-track analysis and real-time monitoring. Harness Pure Dynamics for psychoacoustic clarity.
Partiels is an audio analysis application that allows you to explore the content and characteristics of sounds.
Features:
Partiels allows analysis of one or several audio files using Vamp plug-insloading data files, visualizing, editing, organizing, and exporting the results as images or text files that can be used in other applications such as Max, Pure Data, Open Music, etc.
Windows, Mac & Linux support
Multiformat support
Multichannel support
Multiaudiofile support
Analyzing audio with Vamp plug-ins
Visualizing results as spectrogram, lines, and markers
Loading results from CSV, LAB, JSON, CUE & SDIF formats
Batch processing
Command line interface to analyze, export, and convert results
Consolidating documents for sharing
Alongside Partiels, a wide range of analyses based on audio engines developed at IRCAM and outside are ported to Vamp plug-ins. These plug-ins allow you to perform FFT, LPC, transient, fundamental, formant, tempo, TTS and many other analyses. You can also find a large number of analysis plug-ins on the Vamp plug-ins website.
foo_vis_spectrum_analyzer is a foobar2000 component that implements a spectrum analyzer panel. It is an attempt to recreate the foo_musical_spectrum component by fismineur for foobar2000 64-bit.
