How to detect a short and simple audio melody

#1

I would like to detect a short and simple audio melody (about 6sec) to indicate that washing machine has finished. I would likeI to use an Arduino Nano Rp2040 connect. Please help me to choose the correct technology. Is It Sound Classifier in Edgeimpulse Studio?
Thanks a lot

Hi @Adelio_Trezzi

That is audio event detection and classification, if you follow through the create impulse our blocks have stars next to the relevant blocks for your data and the descriptions will tell you what ones work for your solution:

The blocks you will need are:

Audio (MFE) - Extracts a spectrogram from audio signals using Mel-filterbank energy features, great for non-voice audio.

Classification - Learns patterns from data, and can apply these to new data. Great for categorizing movement or recognizing audio.
