Скачать или смотреть Web Audio API visualizer: A visual mockup of auto-equalization effect

This is a visual-only mockup of what would auto-equalization/spectral balancer DSP/effects be like in terms of frequency response view, but this is not 100% accurate representation of such type of DSPs

Settings on this altered version of my own project:
Frequency scale and range: 0Hz-20kHz within Mel scale
Transform algorithm: FFT with triangular Mel filter bank (magnitude FFT data used)
FFT size: 2400 samples (exact 50ms on 48kHz sample rate)
dB range: 0dB to -120dB (inverted to show as a mockup of what would spectral balancers looks like)
Frequency weighting: 3dB per octave upward slope and inverse C-weighting

Project used in this video: Altered version of this below (not public, adds the gain compensation by a sum of all frequency band magnitudes)

Song name: The Hamster Alliance - Murder Taxi (also known as the extended version of this song from Audiosurf 1 trailer)
   • Murder Taxi (Hamster Alliance)   (   • Audiosurf 1 Trailer  )

Disclaimer: No audio is manipulated on this video in any way (other than Stable Volume feature on YT if available and enabled in this video) as it is just a visual mockup and please, don't rely solely on your eyes for mixing and mastering

Update: I've made a public one that actually alters audio (Automatic spectral balancer effect using AudioWorklet)
