Question/Issue:
There’s a feature in data acquisition that allows a user to split longer audio samples into chunks of specific length (e.g. 5 seconds) containing the “meaningful” information, such as a keyword. It is used in the Responding to your voice - Edge Impulse Documentation (gitbook.io) tutorial.
This is a great feature, however it is manual and with >100 audio samples it becomes unusable. Is the source code for this feature available anywhere so that one may pre-process the data in bulk prior to upload? Would also be interesting to know how it works since I can see that it sometimes does not match what I want.
If you want to automate this process, you can have also look at our transformation blocks, it is a typical use case for the transformation blocks.
I am not sure the source code is currently publicly available, I’ll ask around and will let you know.
@louis out of curiosity the actual code that makes this happen would be interesting to see, been trying a bunch of librosa methods but don’t quite get the same behavior nor ease.
