This plugin is compatible with the ComfyUI audio nodes.

Audio Waveforms

| Name | Description | |----------------------|-------------------------------------------------------------------------------------| | Load Audio From Path | Same as "Load Audio" but loads from a local path instead of an uploaded audio file. | | Plot Waveform | Plots the waveform of an AUDIO object. |

Spectrograms

| 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. | | Plot Spectrogram | Plots the spectrogram of a SPECT 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);

Complex-Valued Spectrograms

Real-Valued Spectrograms

Filter Banks

| Name | Description | |-----------------------|-----------------------------------------------------| | Linear Filter Bank | Create a linear filter bank. | | Mel-scale Filter Bank | Create a mel-scale filter bank. | | Apply Filter Bank | Apply the specified filter bank to the spectrogram. | | Plot Filter Bank | Plots the FILTER_BANK object. |
