Vocoder.Dunai

This module wraps phase vocoder algorithms for use in Dunai and Rhine.

Documentation

volumeFix :: Monad m => VocoderParams -> MSF m Frame Frame

Corrects for volume change introduced by STFT processing.

analysis :: (Traversable t, Monad m) => VocoderParams -> Phase -> MSF m (t Frame) (t STFTFrame)

Perform the phase vocoder analysis phase.

synthesis :: (Traversable t, Monad m) => VocoderParams -> Phase -> MSF m (t STFTFrame) (t Frame)

Perform the phase vocoder synthesis phase.

processFrames :: (Traversable t, Monad m) => VocoderParams -> MSF m (t STFTFrame) (t STFTFrame) -> MSF m (t Frame) (t Frame)

Perform frequency domain processing on overlapping frames.

process :: Monad m => VocoderParams -> MSF m [STFTFrame] [STFTFrame] -> MSF m Frame Frame

Perform frequency domain processing on a chunked stream. The chunks' size must be a multiple of the vocoder's hop size.

framesOfS :: forall a m. (Storable a, Num a, Monad m) => Length -> HopSize -> MSF m (Vector a) [Vector a]

Splits a chunked input stream into overlapping frames of constant size suitable for STFT processing. The input and output chunks' size must be a multiple of the vocoder's hop size.

sumFramesS :: forall a m. (Storable a, Num a, Monad m) => Length -> HopSize -> MSF m [Vector a] (Vector a)

Builds a chunked output stream from a stream of overlapping frames. The input and output chunks's size must be a multiple of the vocoder's hop size.

sumFramesWithLengthS :: forall a m. (Storable a, Num a, Monad m) => HopSize -> MSF m ([Vector a], Length) (Vector a)
