Audio nodes

utilities for nodes that output audio data.

Channel Filter audio.channel

selects audio channels from audio data.

Gain audio.gain

adjusts the volume of an audio.

Limiter audio.limiter

limits the audio volume by a threshold.

MFCC audio.mfcc

turns audio data into coefficients that can be useful for phoneme/speaker recognition.

these coeficients can be pretty abstract; you can use its data by combining it with a Scores Match node, which then lets you record voice samples and thus calibrate your own lipsync solution, for example.

Cherry Lip Sync audio.cherrylipsync

takes audio data and estimates lipsync animation information.

Oculus Lip Sync audio.ovrlipsync

takes audio data and estimates lipsync animation information.

RNNoise audio.rnnoise

takes audio data and removes any potential noise, also estimates whether there’s speech present or not.

Silero VAD audio.silerovad
