Vocoder.Audio

Description

This module allows easy frequency-domain processing on audio streams created in conduit-audio.

Synopsis

data VocoderAudioSource m = VocoderAudioSource {
- sourceV :: (Frame, (ZipList Phase, ZipList Phase)) -> ConduitT () Frame m (Vector Double, (ZipList Phase, ZipList Phase))
- rateV :: Rate
- channelsV :: Channels
- framesV :: Frames
- vocoderParamsV :: VocoderParams
}
concatenateV :: Monad m => VocoderAudioSource m -> VocoderAudioSource m -> VocoderAudioSource m
sourceVocoder :: Monad m => VocoderAudioSource m -> AudioSource m Double
sourceVocoderWithPhase :: Monad m => Phase -> VocoderAudioSource m -> AudioSource m Double
processAudio :: Monad m => VocoderParams -> Filter m -> AudioSource m Double -> AudioSource m Double
processAudioWithPhase :: Monad m => VocoderParams -> Phase -> Filter m -> AudioSource m Double -> AudioSource m Double
processVocoderAudio :: Monad m => VocoderParams -> Filter m -> AudioSource m Double -> VocoderAudioSource m

Constructors

VocoderAudioSource
Fields sourceV :: (Frame, (ZipList Phase, ZipList Phase)) -> ConduitT () Frame m (Vector Double, (ZipList Phase, ZipList Phase)) rateV :: Rate channelsV :: Channels framesV :: Frames vocoderParamsV :: VocoderParams

concatenateV :: Monad m => VocoderAudioSource m -> VocoderAudioSource m -> VocoderAudioSource m Source #

Connects the end of the first vocoder source to the beginning of the second. The two sources must have the same sample rate, channel count, vocoder hop size and frame length.

sourceVocoder :: Monad m => VocoderAudioSource m -> AudioSource m Double Source #

Creates an audio source from a vocoder source.

sourceVocoderWithPhase :: Monad m => Phase -> VocoderAudioSource m -> AudioSource m Double Source #

Creates an audio source from a vocoder source, with initial phase provided.

processAudio :: Monad m => VocoderParams -> Filter m -> AudioSource m Double -> AudioSource m Double Source #

Applies a conduit filter to an audio stream.

processAudioWithPhase :: Monad m => VocoderParams -> Phase -> Filter m -> AudioSource m Double -> AudioSource m Double Source #

Applies a conduit filter to an audio stream, with initial phase provided.

processVocoderAudio :: Monad m => VocoderParams -> Filter m -> AudioSource m Double -> VocoderAudioSource m Source #

Applies a conduit filter to an audio stream, producing a vocoder stream. This allows to seamlessly concatenate audio streams for vocoder processing.
