The sound equalizer is using the Audaspace FFT Convolver. The blender part creates an array of descriptions of power per "band" and orders the creation of Equalizer (ISound) in the Audaspace. Modifier can be created on sound strips. It lets you define amplification or attenuation over frequency range from 30Hz to 20 kHz. The power is limited to -30 db - 30 db. This is done using curve mapping widget.

audaspace
Audaspace (pronounced "outer space") is a high level audio library written in C++ with language bindings for Python for example. It started out as the audio engine of the 3D modelling application Blender and is now released as a standalone library.
Documentation and Community
The documentation including guides for building and installing, demos, tutorials as well as the API reference for C++, C and python can be found on https://audaspace.github.io.
Bug reports and feature requests should go to the issue tracker.
For any other discussions about audaspace there is a mailing list and there is also the IRC channel #audaspace on irc.freenode.net.
Features
The following (probably incomplete) features are supported by audaspace:
- input/output devices
- input from microphones, line in, etc.
- output devices including 3D audio support
- file reading/writing
- filters like low-/highpass and effects like delay, reverse or fading
- generators for simple waveforms like silence, sine and triangle
- respecification - this term is used for changing stream parameters which are
- channel count - channel remapping
- sample format - the library internally uses 32 bit floats
- sample rate - resampling
- simple (superposition, joining and ping-pong aka forward-reverse) and more complex (non-linear audio editing) sequencing of sounds
