Nomi516/Material-Identification-using-Signal-Processing-Techniques-for-Waste-Management- ? reverse-engineered prompt

Build me a Python app that can पहचान? No, in plain English, build me a simple tool that listens to a tap or scrape sound and tells me whether the material is glass, plastic, steel, or metal.

I want a clean desktop GUI where I can either record from the microphone in real time or load a .wav file, then see the predicted material and the audio features that were used, like ZCR, RMS, spectral centroid, bandwidth, roll off, and MFCCs. Please make it work with a rule based classifier rather than machine learning, and include a fallback result when the audio is unclear. It would also be great if it can save past predictions to a spreadsheet or CSV for later review.

If useful, create the feature extraction and visualization parts too, like waveform and feature plots, and make the whole thing easy to run from one place. If you need to check current docs for audio or GUI libraries, go ahead and look them up online.
