Vocoder.Conduit

This module wraps phase vocoder algorithms for use in Conduit. Two variants are provided, one for single channel processing, and another for processing multiple channels synchronously.

Single-channel functions

volumeFix :: Monad m => VocoderParams -> ConduitT STFTFrame STFTFrame m ()

Corrects for volume change introduced by STFT processing.

analysis :: Monad m => VocoderParams -> Phase -> ConduitT Frame STFTFrame m Phase

Perform the phase vocoder analysis phase.

synthesis :: Monad m => VocoderParams -> Phase -> ConduitT STFTFrame Frame m Phase

Perform the phase vocoder synthesis phase.

processFrames :: Monad m => VocoderParams -> (Phase, Phase) -> ConduitT STFTFrame STFTFrame m r -> ConduitT Frame Frame m (r, (Phase, Phase))

Perform frequency domain processing.

Multi-channel functions

volumeFixF :: (Applicative f, Monad m) => VocoderParams -> ConduitT (f STFTFrame) (f STFTFrame) m ()

Corrects for volume change introduced by STFT processing.

analysisF :: (Applicative f, Monad m) => VocoderParams -> f Phase -> ConduitT (f Frame) (f STFTFrame) m (f Phase)

Perform the phase vocoder analysis phase.

synthesisF :: (Applicative f, Monad m) => VocoderParams -> f Phase -> ConduitT (f STFTFrame) (f Frame) m (f Phase)

Perform the phase vocoder synthesis phase.

processFramesF :: (Applicative f, Monad m) => VocoderParams -> (f Phase, f Phase) -> ConduitT (f STFTFrame) (f STFTFrame) m r -> ConduitT (f Frame) (f Frame) m (r, (f Phase, f Phase))

Perform frequency domain processing.
