comfyui-audio-plugin

A collection of nodes for working with audio data.

• I/O
• Plotting
• Spectrogram
• License

Note

This plugin is compatible with the ComfyUI audio nodes.

I/O

Name	Description
Load Audio From Path	Same as "Load Audio" but loads from a local path instead of an uploaded audio file.

Filter Banks

Name	Description
Mel-scale Filter Bank	Create a mel-scale filter bank.
Apply Filter Bank	Apply the specified filter bank to the spectrogram.

Plotting

Name	Description
Plot Waveform	Plots the waveform of an AUDIO object.
Plot Spectrogram	Plots the spectrogram of a SPECT object.
Plot Filter Bank	Plots the FILTER_BANK object.

Spectrogram

Name	Description
Spectrogram	Computes the spectrogram of a given AUDIO object.
Inverse Spectrogram	Converts a complex-valued spectrogram to AUDIO.
Griffin Lim	Converts a real-valued spectrogram to AUDIO using the Griffin-Lim algorithm.
Mel-scale Spectrogram	Computes the mel-scale spectrogram of a given AUDIO object.

A spectrogram (SPECT) can be one of three types:

1. complex – a complex number valued spectrogram;
2. magnitude – a real valued spectrogram that is the absolute value of the complex spectrogram (power 1);
3. power – a real valued spectrogram that is the square of the magnitude spectrogram (power 2);

A mel-scale spectrogram (MEL_SPECT) is a magnitude or power spectrogram that has been converted to the mel audio scale.
