h1. Preprocessing options to be implemented
h2. Flatten dynamics
Integrating the "Flatten Dynamics plugin":/projects/flattendynamics
h2. De-envelope
Using cepstral processing to factor out the spectral envelope, after "Simple Cepstrum":/projects/vamp-simple-cepstrum
h2. Remove broadband noise
Like the initial noise-removal phase of "Silvet":/projects/silvet -- which runs noise removal on the constant-Q spectrum, but I expect the method would work unchanged for STFT as well
h2. Remove pitched sounds
For symmetry with "Remove broadband noise", something that filters out stable pitched sinusoidal or harmonic content in the manner of the "Devuvuzelator":/projects/devuvuzelator (does this have any application?)
h2. Add broadband noise
Surprisingly turned out to have a potential application in MATCH: adding -30dB white noise to the inputs gave a more stable alignment
