I am starting a new project and want to build a custom audio classifier using the great website Teachable machine and his speech-commands model.
I have collected audio samples from a personal user interface, and now i have many wav files available.
My goal is to upload them inside teachable machine website, following the audio zip format, which is just a zip file containing :
- all the samples sound files for a class concatenated inside a single webm file
- a json file explaining for each sound sample his audio characteristics.
Using a simple Node.js script file, i achieve to concatenate my files, and creating the json file.
The last missing information foreach file is an attribute called “frequencyFrames”. For a sample i have downloaded from TM (and created online using microphone), it is an array of array.
Is someone knows how can i get this information for each wav file ?
