Amazon Music LUFS (and the −2 dBTP Rule)

Updated August 2026 · by Loopin

Amazon Music normalizes to about −14 LUFS integrated like most platforms, but it recommends a stricter −2 dBTP true-peak ceiling instead of −1 — because Alexa and Echo devices are prone to inter-sample (true-peak) clipping. That −2 dBTP rule is the one thing that sets Amazon apart from Spotify, Apple and YouTube. You can master to it free in Loopin’s browser mastering.

What LUFS does Amazon Music use?

Amazon Music normalizes playback to about −14 LUFS integrated, the same reference used across most streaming platforms. It turns louder masters down and softer masters up so everything plays at a consistent volume.

So the loudness target is nothing exotic — if you already master to −14 LUFS for Spotify, you’re on the right loudness for Amazon too. The difference is the peak ceiling.

Integrated loudness reference: about −14 LUFS
Same as: Spotify, Apple Music, YouTube, Tidal
Effect: masters are normalized toward −14 LUFS on playback
The catch: a stricter true-peak ceiling — see below

The −2 dBTP rule (the key differentiator)

Here’s where Amazon Music diverges. Most platforms — Spotify, Apple Music, YouTube — accept a −1 dBTP true-peak ceiling. Amazon Music recommends a stricter −2 dBTP.

The reason is hardware: Alexa and Echo devices are prone to inter-sample (true-peak) clipping. Inter-sample peaks are level spikes that appear between samples when audio is reconstructed for playback — a signal that measures under 0 dBFS on the samples can still overshoot on the actual output. The extra decibel of headroom keeps those overshoots from clipping on Amazon’s smart speakers.

Amazon Music: −2 dBTP ceiling
Spotify / Apple Music / YouTube: −1 dBTP is fine
Why stricter: Alexa/Echo devices can clip on inter-sample peaks
Takeaway: give Amazon an extra decibel of true-peak headroom

The target to master for

For Amazon Music specifically, the loudness is standard and only the peak ceiling changes. Aim for:

Integrated loudness: about −14 LUFS
True peak: −2 dBTP ceiling (stricter than the usual −1)
Priority: dynamics and clarity over raw loudness
Format: a clean, full-quality WAV

How to master for Amazon Music

From finished mix to an Amazon-ready master:

Bounce your mix to WAV with headroom — peaks near −6 dB, no mix-bus limiter.
Open Loopin’s free mastering tool and drop the file in.
Let the chain target streaming loudness (about −14 LUFS integrated).
For Amazon, set the true-peak ceiling to −2 dBTP rather than the usual −1, giving Echo/Alexa devices extra headroom.
A/B against the original, confirm the peak sits at −2 dBTP, and download the 16-bit WAV.
Upload the WAV to your distributor for Amazon Music.

Common mistakes

The most common trap is treating Amazon like every other platform and reusing a −1 dBTP master. It’ll usually sound fine on phones and headphones, which is why the problem slips through — the inter-sample clipping only rears its head on the Echo and Alexa hardware you may not be testing on. Building in the extra decibel of headroom costs you nothing perceptible and removes the risk entirely.

Using a −1 dBTP master for Amazon — it can inter-sample clip on Echo/Alexa; give it −2 dBTP.
Mastering hotter than −14 LUFS — Amazon normalizes it back down and keeps the distortion.
Assuming true peak equals sample peak — inter-sample peaks can overshoot even when samples read under 0 dBFS.
Testing only on headphones — the clipping risk shows up on smart speakers, so keep the extra headroom.
Delivering a pre-crushed MP3 — send a clean full-quality WAV instead.

What inter-sample peaks actually are

The −2 dBTP rule only makes sense once you understand what a true peak is. Digital audio stores a series of samples — snapshots of the waveform. When a converter reconstructs the smooth analog signal for playback, the curve it draws between those samples can rise higher than any single sample value. That overshoot is an inter-sample peak, and true-peak (dBTP) metering estimates it.

A master can read −0.1 dBFS on its sample peaks yet still produce inter-sample peaks above 0 dBTP on playback. On a well-designed DAC that’s often harmless, but on Alexa and Echo hardware it can clip audibly. That’s exactly why Amazon Music asks for the extra decibel of headroom.

So ‘true peak’ is not the same as the peak level your DAW shows on its sample meter. Use a true-peak meter (or a limiter with a true-peak mode) and set the ceiling to −2 dBTP for Amazon.

Sample peak: the highest stored sample value
True peak (dBTP): the highest level after analog reconstruction, including overshoots between samples
A track under 0 dBFS on samples can still exceed 0 dBTP on playback
Amazon’s −2 dBTP ceiling buys headroom so Echo/Alexa don’t clip

One master, or a dedicated Amazon version?

A −14 LUFS master with a −1 dBTP ceiling is a fine universal choice for Spotify, Apple, YouTube and Tidal. For Amazon Music, the safest move is a version with the −2 dBTP ceiling — same loudness, just an extra decibel of peak headroom.

If you only want to keep one master, mastering everything to −2 dBTP is the conservative option: it satisfies Amazon and stays well within every other platform’s −1 dBTP requirement too.

Master it free

Loopin’s online mastering targets about −14 LUFS integrated with a true-peak limiter, runs entirely in your browser — free, no signup, nothing uploaded, no watermark — and exports a clean 16-bit WAV. Aim for a −2 dBTP ceiling and your master will hold up on Echo and Alexa without inter-sample clipping.

Frequently asked questions

What LUFS should I master for Amazon Music?

About −14 LUFS integrated, the same as most platforms. The difference is the true-peak ceiling: Amazon recommends a stricter −2 dBTP rather than the −1 dBTP used elsewhere.

Why does Amazon Music want −2 dBTP instead of −1?

Because Alexa and Echo devices are prone to inter-sample (true-peak) clipping. The extra decibel of headroom keeps those overshoots — peaks that appear between samples on playback — from clipping on Amazon’s smart speakers.

Is Amazon Music’s loudness different from Spotify’s?

No, the loudness is the same — both normalize to about −14 LUFS integrated. What differs is the true-peak ceiling: Amazon asks for a stricter −2 dBTP, while Spotify, Apple Music and YouTube accept −1 dBTP.

Can I use one master for Amazon and Spotify?

You can if you master to −2 dBTP: that satisfies Amazon’s stricter ceiling and stays comfortably within the −1 dBTP that Spotify and others allow. A −1 dBTP master is fine everywhere except Amazon’s smart speakers.

Can I master for Amazon Music for free?

Yes. Loopin’s free browser mastering targets about −14 LUFS with a true-peak limiter, runs entirely in your browser with nothing uploaded, and exports a 16-bit WAV. Aim for a −2 dBTP ceiling for Amazon.
