Could you build this?

Partial While local audio classification is feasible with open-source audio ML models in an Electron app, maintaining an audio-fingerprinted index of 18 million commercial tracks requires major web-scale indexing infrastructure.

What it would actually take: The desktop client would use Electron/Tauri with an ONNX/PyTorch audio embeddings model (e.g., CLMR or Essentia) to extract acoustic features from local files. The hard part is the discovery backend: constantly scraping, embedding, and indexing 18 million music tracks from Beatport and Bandcamp into a large-scale vector database (Milvus/Pinecone) with scalable acoustic similarity search. This requires music information retrieval (MIR) expertise and substantial data engineering pipelines.
