Spectrogram Augmenter
Configure and create a spectrogram data augmentation. You can also store it in a datastore for machine learning with automated batching.
Configure and create a spectrogram data augmentation. You can also store it in a datastore for machine learning with automated batching. This implements two classes:
- spectogramDataAugmenter: configure the augmentation for the spectograms. Similar to imageDataAugmenter for images.
- augmentedSpectrogramDatastore: transform batches to augment spectrogram data. Similar to augmentedImageDatastore for images.
The techniques implented are:
- Time warp
- Frequency masking
- Time masking
- Salt and pepper noise
- White noise
- Time shift
The first three filters are from "SpecAugment: A Simple Data Augmentation Method for Automatic Speech Recognition" by Google Brain and its authors Daniel S. Park, William Chan, Yu Zhang, Chung-Cheng Chiu, Barret Zoph, Ekin D. Cubuk & Quoc V. Le.
