Not really. I am trying to use Teachable Machine interface with wav files i have collected for a side project, and training a model with these sounds.
There is only one way to import sounds in Teachable machine : previous sounds recorded with the interface and downloaded on my computer for example.
I have tried (explained in my first message) to reproduce the structure of the zip file i got when i download a Teachable machine class.
I have found some interesting classes in tfjs speech commands source code (https://github.com/tensorflow/tfjs-models/tree/master/speech-commands/src 4), but didn’t find a way to recreate frequencyFrames data.
I have all my wav files offline, and a Node.js script to loop on them and recreate the needed Teachable machine zip file.
