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.

Plotting

Name	Description
Plot Waveform	Plots the waveform of an AUDIO 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.
