# AI Mastering for Streaming: -14 LUFS for All Platforms or Custom?

Hannah Morgan · November 6, 2026

> For streaming-only releases, make one master at -14 LUFS integrated with true peak at or below -2 dBTP; custom masters only with a written spec.

## Single Anchor vs Custom Masters: Pick the Winner

For a streaming-only release, make one master at -14 LUFS integrated with true peak at or below -2 dBTP. That is Option A in the table, and it is the winner for this use case. The rule is simple: one file, one target, and one QC pass unless a written spec says otherwise.

| Option | Master | Streaming-only verdict |
| --- | --- | --- |
| A | One -14 LUFS integrated / -2 dBTP streaming master | Winner |
| B | Custom per-platform masters | Only with a written per-platform spec |
| C | Custom per-use masters for club, broadcast, or immersive | Only for that playback chain |

Option A wins because it is the only option tied to the three-source convergent anchor for 2026 streaming delivery. It also avoids the main failure mode of custom masters: multiplying files without multiplying verified targets. One master means one loudness check, one true-peak check, and one revision path if QC fails. That is the practical advantage for a release with no conflicting written spec.

Option B adds deliverables, not evidence. It wins only when a distributor or platform document states a different written integrated target for that destination. If the document is absent, a per-platform master is a guess with extra file management, not a better master. The burden is on the document, not on the mastering engineer.

Option C is for a different playback chain, such as club, broadcast, or immersive playback. It should be used only when that non-streaming spec supplies its own written integrated target. For ordinary streaming release, it solves the wrong problem and can create version confusion.

## Costs That Matter: $250 per Track and QC Bounces

For a 2026 streaming-only release, the real budget question is rarely a platform upload fee. The costs that move are mastering labor and the number of quality-control passes your team must complete before delivery. Treating loudness as a per-platform manufacturing problem can turn one release into several paid masters and several rounds of measurement, even when the playback destination is the same set of streaming services.

Freshly Baked Studios lists online mastering starting at $250 per song for house music. Use that figure as a reference point for custom or outsourced mastering work, not as a per-platform streaming charge. If you commission separate masters for different streaming targets, each additional version can carry its own mastering cost, revision cycle, and approval step. Before paying for that split, confirm whether a distributor or platform has provided a written delivery specification that actually requires a different integrated loudness target.

Automated tools can change the cash outlay, but they do not remove the need to verify the final deliverable. eMastered advertises “Try It For Free” on its mastering page; the available grounding does not provide a per-export price, so verify the checkout terms, export limits, and file format before budgeting a release around it. A free trial can be useful for testing a workflow, but the production decision should still be based on the measured output file you intend to deliver.

The quieter cost is quality control. A custom deliverable set multiplies QC passes by the number of masters: every version needs its own bounce, loudness measurement, true-peak check, file naming review, and listening pass against the approved reference. A single streaming master needs one bounce-and-remeasure pass. A practical check is to count masters before you count songs: if one track becomes three deliverables, you have created three separate opportunities for a wrong file, a stale revision, or an unmeasured export to reach distribution.

For most streaming-only projects, the lower-cost path is to finish one measured master, document its integrated loudness and true-peak readings, and archive that file as the streaming deliverable. Create an additional custom master only when a written delivery spec or a non-streaming playback chain requires a different integrated target, because that is the point where extra mastering spend and extra QC work are tied to a documented requirement rather than to assumption.

## What the Loudness Evidence Does Not Establish

The available 2026 grounding supports a general streaming delivery pair, but it does not establish binding, per-platform loudness mandates. This section alone states that Spotify, Apple Music, and YouTube per-platform integrated LUFS and true-peak values are absent from the available sources and must be checked before you create any custom target. Sources such as imseankim.com and Quantara Music describe a general streaming target of -14 LUFS integrated with true peak at or below -2 dBTP, yet the snippets do not provide official platform specification numbers you can treat as delivery requirements.

CP3 is the checkpoint that prevents avoidable rework. After encoding the CP2 master to AAC and measuring the encoded file, the reading shifts to -13.9 LUFS integrated / -1.7 dBTP. The loudness remains effectively on target, but the true peak now exceeds the -2.0 dBTP ceiling. The fix is mechanical: lower the limiter ceiling to -2.4 dBTP, render again from the pre-encode master, and confirm the final file measures -14.0 LUFS / -2.4 dBTP.

The wrong-way cost is concrete. Shipping the -1.7 dBTP codec overshoot means the delivery file fails the peak check you intended to pass, which triggers one emergency re-bounce and a second round of upload or QC. Catching the overshoot at CP3 keeps the correction inside the same mastering session, where the only change is a ceiling adjustment and a fresh export.

Use this worksheet as a repeatable gate for 2026 streaming-only releases: measure the source, calculate gain, verify the limited bounce, audition the delivery codec, and ship only after the encoded file meets both the integrated loudness target and the true peak ceiling. If a distributor or platform provides a conflicting written delivery specification, follow that document instead of this checkpoint target.

## Worked Example: Run the Numbers

**Calculation step 1 (illustration):** Compute the integrated loudness offset needed to move the example master from -8.0 LUFS to -14.0 LUFS. Offset = target integrated LUFS − measured integrated LUFS = -14.0 − (-8.0) = -14.0 + 8.0 = -6.0 dB. The example file must be reduced by 6.0 dB of integrated gain to reach the -14.0 LUFS delivery target.

**Calculation step 2 (illustration):** Apply the same 6.0 dB reduction to the measured true peak to estimate the post-adjustment ceiling. Resulting true peak = -0.8 dBTP + (-6.0 dB) = -6.8 dBTP. Check: -6.8 dBTP is lower than (more headroom than) -2.0 dBTP, so the adjusted file passes the -2 dBTP true-peak limit in this example. As a delivery check, confirm both values in your meter before export: integrated loudness at -14.0 LUFS and true peak at or below -2.0 dBTP (Peak-Studios’ 2026 streaming upload guidance describes measuring integrated LUFS and true peak on the final master).
