Module similarity 

Audio similarity search via spectral fingerprinting.

Computes a feature vector for each audio file using fast energy-band analysis (no DFT needed). Compares fingerprints using euclidean distance to find similar-sounding samples. Fingerprints are cached to avoid recomputation.

Structs

AudioFingerprint

Audio fingerprint — a compact feature vector for similarity comparison.

Functions

compute_fingerprint

Compute a fingerprint for an audio file using fast energy-band analysis.

find_similar

Find the N most similar samples to a reference fingerprint.

fingerprint_distance

Compute distance between two fingerprints (lower = more similar).
