Analyze the WaveCap-SDR audio stream to assess tuning quality, detect silence, noise, proper audio, or distortion. Use when checking if SDR channels are properly configured or debugging audio issues.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Audio Quality Checker for WaveCap-SDR This skill helps analyze the audio stream from WaveCap-SDR channels to determine if they are properly tuned and producing usable audio. ## When to Use This Skill Use this skill when: - User asks to check if an SDR channel is "well tuned" or working properly - User wants to verify audio quality or detect issues - User asks if they're getting "real sound" vs "just noise" vs "nothing" - Debugging why audio playback isn't working as expected - Validating SDR configuration changes ## How It Works The skill captures a sample of the audio stream and analyzes it to detect: 1. **Silence** - No signal, near-zero amplitude (broken/stopped channel) 2. **Noise** - Random signal with no structure (poor tuning, no carrier) 3. **Proper Audio** - Structured signal with meaningful content (well-tuned FM station) 4. **Clipping/Distortion** - Signal hitting limits (gain too high, overmodulation) ## Usage Instructions ### Step 1: Identify the Server and Channel First, determine: - Server port (default: 8087, check `backend/config/wavecapsdr.yaml` or environment variables) - Channel ID to test (e.g., "ch1", "ch2", etc.) - Server bind address (default: 127.0.0.1) Y

What does the audio-quality-checker skill do?
Analyze the WaveCap-SDR audio stream to assess tuning quality, detect silence, noise, proper audio, or distortion. Use when checking if SDR channels are properly configured or debugging audio issues.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill audio-quality-checker --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.
