## 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.
