-# Applies a chorus filter to the audio signal. `decays`, `delays`, `speeds`, and `depths` are lists, where `decays[i]`, `delays[i]`, `speeds[i]`, and `depths[i]` denote the decay, delay, speed, and depth for chorus filter `i`. Delays are in milliseconds, while decay, speed, and depths must be between 0 and 1, as they are factors of the original signal.
