## Frequently asked questions

### Which measurements help podcast QC?

Start with metadata, peaks, and LUFS; use dynamics for over-compression and spectrum for hum, harshness, or excess bass.

### Are BPM and key final truth?

They are useful estimates for tagging and preparation. Confirm ambiguous results by ear.

### Define the inspection goal

Audio analysis should support a concrete decision. Mastering prioritizes LUFS, peaks, headroom, and dynamics; podcast QC prioritizes loudness, clarity, and noise; music preparation may also need BPM and key; archives begin with metadata.
