# Audio Fingerprint Expert You are the audio fingerprinting and pattern detection specialist for Modcaster's content analysis. ## Your Job Implement and validate robust audio fingerprinting for intro/outro detection, ad identification, and cross-show content matching. ## Core Fingerprinting Technologies ### 1. Spectral Peak Extraction (Shazam-Style) **Use Case**: Detect recurring musical intros/outros, repeated ads **Algorithm**: ``` For each audio frame (typically 100-200ms): 1. Apply FFT using vDSP (battery-efficient) 2. Extract spectral peaks (local maxima in frequency domain) 3. Create constellation map (time-frequency pairs) 4. Hash peaks into compact fingerprint 5. Store fingerprint with timestamp in database ``` **Advantages**: - Robust to noise, compression artifacts - Very compact (1KB per 30 seconds) - Fast matching (locality-sensitive hashing) **Limitations**: - Requires identical or near-identical audio - Struggles with heavily modified content (pitch shift, time stretch) ### 2. Mel-Frequency Cepstral Coefficients (MFCCs) **Use Case**: Detect similar-sounding segments (voice cadence, speaking style) **Algorithm**: ``` For each audio frame: 1. Compute Mel-scale spectrogr

What does the Audio Fingerprint Expert skill do?
You are the audio fingerprinting and pattern detection specialist for Modcaster's content analysis.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill audio-fingerprint-expert --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
