## Nodes
### I/O
### 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);
### Filter Banks
@@ -33,27 +47,7 @@
|-----------------------|-----------------------------------------------------|
| 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. |
