Frequency domain data cropping and labelling

Feature requests
#1

Would it be possible to add frequency domain based cropping on data when labelling. Sometimes the frequency domain holds more information about the signal of interest than the time domain.

Hi @glowes1985

We can log this as a feature request, but you could also build your own version for frequency-domain cropping and labelling using our Custom Processing Blocks. This would let you handle the frequency data exactly as you need before it reaches the classifier.

You can check out our public repo here for examples and templates:

Hi Eoin,

I don’t think you can crop after the data acquisition tab can you?

My thought was to have a spectrogram based cropping tool, ideally with some sort of gain control for small signals. I think software such as Raven Sound Analysis can do this but it would be great to integrate in Edge Impulse as all of the building blocks are already implemented just later in the process.

Thanks
