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

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

Creates an audio source from a vocoder source.

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

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

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

Applies a conduit filter to an audio stream.

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

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

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

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