RMS
Real-time safe, per-sample (ticked by UI thread) RMS calculation.
Peak detector
Peak detector with adjustable attack/release times.
FFT
rustfft
audio-processor, forwards or backwards, real-time safe, FFT.
Applies a Hann window by default. Several window functions are exported by window_functions
.
Then performs FFT with N bins.
Overlap is configurable
Envelope follower
Envelope follower implementation with adjustable attack/release times.
Transient detection
Implements "A Transient Detection Algorithm for Audio Using Iterative Analysis of STFT.".
Does polyphonic transient detection, able to output signal or markers
Window functions
Several window functions are implemented and configurable.
