Mastered to the spec your chain expects.
Every approved cut is mastered once at 48 kHz / 24-bit, then rendered to each profile you selected. Pick as many as you need; they cost nothing extra.
| Profile | Integrated loudness | True peak | Files |

| Radio — terrestrial (AM/FM/DAB/HD)cart chunk | Your own reference, imaging +1 LU | -1 dBTP | WAV PCM 48 kHz / 24-bit |
| Radio — satellitecart chunk | -20 LUFS ±1 LU | -1 dBTP | WAV PCM 48 kHz / 24-bit |

TV — North America (ATSC A/85): US CALM Act and CRTC. CBC/Radio-Canada asks -24 LKFS ±1 LU, -2 dBTP max.
Radio — terrestrial (AM/FM/DAB/HD): No regulated target. Matches the station's measured music library, imaging +1 LU.
Radio — satellite: Placeholder. Each carrier's delivery spec must be entered as its own profile.
Short cuts are levelled differently
An integrated loudness reading on a three-second ID is not meaningful — there is not enough audio to measure. Cuts under 6 seconds are levelled on their maximum short-term loudness and true peak instead, which is how a mastering engineer would handle it by ear.
Radio has no regulated target
Television does, and we follow it. Radio does not — your air-chain processor sets the final on-air level. So we measure a sample of your own music library and deliver imaging a little hotter than it, which is how it sits right when the processor gets hold of it.
Television scope
We deliver audio and stems for your video team. Finished video spots — captions, timecode, slates — are out of scope, and we will say so rather than take the order.
Satellite carriers
Each carrier publishes its own delivery spec. Tell us which carriers you feed and we will set up a profile per carrier rather than guessing at a generic one.
Metadata filled in before it reaches you
BWF bext
Station, product and title in the description; "Radio IDs" as originator; origination date; measured loudness written in so nothing downstream has to re-measure.
AES46 cart chunk
Title, category, cut ID, client ID and out-cue. Start and end dates for dated promos. Intro and end-of-message markers as sample counts, so your system segues correctly on import.
iXML
Order ID and take ID. A file found loose in an automation system can be traced straight back to the order that produced it.
