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:
|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 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.
