Streaming University

Every standard, specification and code in full — the exact values every render, grade and export in this system must match from the start.

Nothing on this page is summarised or approximated — every number is the agreed value.

Platform quality codes

Sample rate, bit depth, loudness, true peak, dynamic range and file formats for Spotify, Apple Music, Amazon, YouTube, Netflix.

CodeStandardExact valueWhy
PQ-01Sample rate44.1 kHz / 48 kHzStandard for all streaming.
PQ-02Bit depth16-bit minimum, 24-bit preferred
PQ-03Loudness — Spotify / YouTube−14 LUFS integrated
PQ-04Loudness — Apple Music / Amazon−16 LUFS integrated
PQ-05Loudness — Netflix / Film / Broadcast−23 LUFS integrated
PQ-06True peak≤ −1.0 dBTPNo distortion.
PQ-07Dynamic range≥ 12 dBPreserve emotion, do not squash.
PQ-08File formatWAV (master), MP3 320 kbps / AAC 256 kbps (streaming)
