Colab
Colaboratory is also known as Colab. It is a Google Research product that allows one to write code in a web browser. Colab is free with limitations in compute and memory. Upgrading to Colab Pro/Pro+ allows for more compute and memory for a fee. Some, but not all of these notebooks may run in the Colab environment.
To use Colab
- Setup a gmail account if you don't already have one.
- Launch the notebook by clicking on one of the links below:
| Notebook | Description |
|---|---|
| PacificSound2kHz.ipynb | Low-frequency data access and spectrogram calibration |
| PacificSound16kHz.ipynb | Low-mid-frequency data access and spectrogram calibration |
| PacificSound256kHz.ipynb | Raw recording data access and spectrogram calibration |
| PacificSoundListen.ipynb | Listen to example recordings of dolphins and whales, then pick any time to listen and explore |
| PacificSound256kHzTo2kHzDecimate.ipynb | Recommended to learn about how the raw 10-minute data is decimated from 256kHz to 2Khz |
| PacificSoundClassifyBlueA.ipynb | Blue whale A call classification using a trained neural network model |
| PacificSoundBlueBCallIndex.ipynb | Signal processing method for computing Blue whale B call index |
| PacificSound_FinCallindex.ipynb | Signal processing method for computing Fin whale call index |
| PacificSoundShippingNoiseAnalysis.ipynb | Signal processing methods for studying temporal variations in shipping noise |
| PacificSoundDetectHumpbackSong.ipynb | Humpback song detection using a trained neural network model |
Important - there is a 24-hour runtime limit for Colab. This can be an issue for some applications such as training deep-learning models for sound detection and/or classification.
