Overtone GEQ is a free 7-band harmonic (overtone) graphic equalizer AudioUnit, AAX, and VST plugin with multi-channel operation support (supporting up to 8 input/output channels, audio host application-dependent). Overtone GEQ offers extensive internal channel routing capabilities, and supports mid/side channel processing.
Beside equalizing, Overtone GEQ applies harmonic enhancement: it uses 7 harmonic enhancement modules, one for each EQ band. This generates a complex harmonic coloration you will probably like a lot.
Overtone GEQ was designed to allow audio engineers to apply quick EQ shape adjustments together with adding a bit of harmonic richness to the audio material (mainly mixes and sub-mixes due to a comparably high load this EQ puts on a CPU).

Reliably play midi music files from a folder or “.m3u” playlist. Adjust playback speed, volume and output device on the fly during playback. A large playback progress bar makes jumping forward and backward in time a breeze with just a single click or tap. Supports “.mid”, “.midi” and “.rmi” files in format 0 (single track) and format 1 (multi-track). Comes complete with 24 sample midis ready to play.

Seekbar for foobar2000, using Spider Monkey and ffmpeg or audiowaveform. It’s based on RMS or peak levels, instead of the actual waveform.
Features:
- Uses audiowaveform by default (included).
- ffprobe can be used if desired. Download it and copy ffprobe.exe into ‘helpers-external\ffprobe’.
- Visualizer mode to simply show an animation which changes according to BPM (if tag exists).
- VU Meter mode by RMS or peak levels.
- Fully configurable using the R. Click menu:
- Colors
- Waveform modes
- Analysis modes
- VU Meter
- Animations
- Multi-channel display
- Refresh rate (not recommended anything below 100 ms except on really modern CPUs)
Partiels is an audio analysis application that allows you to explore the content and characteristics of sounds.
Partiels allows analysis of one or several audio files using Vamp plug-ins loading 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.
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.

BruteFIR is a software convolution engine, a program for applying long FIR filters to multi-channel digital audio, either offline or in real-time. Its basic operation is specified through a configuration file, and filters, attenuation and delay can be changed in runtime through a simple command line interface. The FIR filter algorithm used is an optimized frequency domain algorithm, partly implemented in hand-coded assembler, thus throughput is extremely high. In real-time, a standard computer can typically run more than 10 channels with more than 60000 filter taps each.
Through its highly modular design, things like adaptive filtering, signal generators and sample I/O are easily added, extended and modified, without the need to alter the program itself.
