The Sync Readiness Guide: Loudness Standards, True Peak & Pitch Delivery Specs
One of the most common misconceptions among indie producers entering sync licensing is that there is a single universal broadcast loudness target. In commercial music streaming, mastering to -8 LUFS is commonplace; in television and film licensing, arbitrary loudness targets can lead to placement friction.
The Client's Technical Specification Sheet ALWAYS takes precedence. Network delivery requirements vary by territory, broadcaster, and platform. When a specific delivery sheet is provided, it supersedes all generalized recommendations.
1. Formal Industry Standards vs. Audition Targets
| Context / Territory | Standard / Platform | Integrated Target | Max True Peak |
|---|---|---|---|
| US Television Broadcast | ATSC A/85 (ITU-R BS.1770) | -24.0 LKFS (±1.0 LKFS) | -2.0 dBTP to -1.0 dBTP |
| European & Global Broadcast | EBU R 128 | -23.0 LUFS (±0.5 LU) | -1.0 dBTP |
| Commercial Streaming | Spotify / Apple / YouTube | -14.0 to -16.0 LUFS | -1.0 dBTP |
| Airtight Sync Pitch Recommendation | Sync Library Audition Master | -14.0 to -12.0 LUFS | -1.0 dBFS True Peak |
Why Airtight Recommends -14 to -12 LUFS for Pitch Audition Files
When music supervisors audition tracks on DISCO.ac or cloud library links, hyper-compressed masters (-7 LUFS) cause listening fatigue and leave zero headroom for dialogue or Foley effects during scene mockups. An audition master calibrated to -14.0 to -12.0 LUFS provides competitive listening energy while preserving the natural dynamic range required by re-recording mixers before final broadcast mastering.
2. The Sync Readiness Score: A 4-Pillar Diagnostic Framework
To give composers and catalog managers a clear, actionable audit of their pitch assets before submission, Airtight Audio created the Sync Readiness Score (0–100):
- Pillar 1: Rights & Split Clearance (35 Points) — 100% master and publishing rights cleared (One-Stop), all writer legal names, PRO affiliations (ASCAP, BMI, SESAC, PRS), and IPI numbers declared with percentages summing to 100%, and direct licensing contact details.
- Pillar 2: Loudness & Headroom Integrity (25 Points) — Alignment with target delivery specs, True Peak limited below -1.0 dBFS, and healthy phase correlation (+0.6 to +1.0) for monophonic fold-down safety.
- Pillar 3: Acoustic & Contextual Precision (25 Points) — Exact BPM, key signature, primary/sub-genres, 3–5 contextual scene moods, vocal status (Lead Male, Lead Female, Instrumental), and core instrumentation.
- Pillar 4: File Format & Ingestion Compatibility (15 Points) — 24-bit lossless WAV master with dual-chunk metadata (ID3v2.4 & RIFF LIST INFO) and accompanying 320 kbps MP3 proxy.
