Colaboratory is also known as Colab. It is a Google Research product that allows one to write code in a web browser. Some, but not all, of these notebooks can be executed in Colab. Colab is free with limitations in compute and memory. Upgrading to Colab Pro/Pro+ allows for more compute and memory for a fee.
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|
|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.
