A detailed description is provided here.
(Sorry in Japanese.)
If you have an Audio Toolbox, you can create a VST/AU plugin from this script. (It's also possible with a Home license.)
Spectrum Breaker is an audio processing plugin that utilizes MDCT (Modified Discrete Cosine Transform) based on Time Domain Aliasing Cancellation (TDAC) theory and auditory psychological characteristics.
MDCT is a technology that converts audio data, such as those used in MP3/AAC compression, into the frequency domain. It is possible to achieve high frequency resolution and frequency analysis accuracy.
Spectrum Breaker uses MDCT to process the audio spectrum. This plugin divides the spectrum into fine segments and applies processing to each segment to generate new sounds. With this processing, you can add unique character to your music and create more attractive sounds.
By using this plugin, you can add a new dimension to your music.
This plugin has seven modes for processing the spectrum in various ways, giving your music a unique sound. Spectrum Breaker automatically detects subtle changes in the spectrum and performs processing based on them, making it easy to use and capable of quickly and effectively processing audio.
