Amazon Music Loudness Target

Recommended Tools

About this Target

Amazon Music exposes a Loudness Normalization playback option but does not publish -14 LUFS as a delivery requirement.

Amazon Music listeners can enable Loudness Normalization for more consistent playback. Its public help does not specify a numeric upload or mastering target. This page therefore uses -14 LUFS Integrated and -2 dBTP as a conservative working reference that leaves extra encoding headroom, not as an Amazon acceptance rule.

Guide: Loudness Leveler

The APU Loudness Leveler is a strong fit when you want to hold a program close to the Amazon Music target continuously rather than force it there with conventional compression or hard limiting. Instead of mapping one loudness range onto another, the Leveler follows a target zone in real time and applies correction only when the program drifts away from where you want it.

Load the Mastering - Amazon Music Reference (Stereo) preset from the Purpose category.

From there, adjust Target Tolerance to control how tightly the audio is held around -14 LUFS. Present tends to work well for general-purpose material, while Deep is useful when you want the correction to follow the larger contour of the audio instead of every phrase-level change.

The built-in Tail Guard mode helps prevent the leveler from amplifying breaths and other relatively quiet moments at the end of phrases, which can lead to a more natural sound. When Tail Guard is enabled, the leveler holds gain correction during these moments, allowing them to sit more naturally in the mix.

The built-in limiter then handles final peak containment at -2 dBTP, which makes the Leveler especially useful for podcasts, dialog-heavy material, streams, and other sources that benefit from steady loudness tracking instead of obvious peak chopping.

Once the other settings are finalized, enable Compensation Learn and play the complete program from start to finish. Turn Learn off when playback finishes to lock the final correction. Run Learn again after any further processing changes.

Guide: Loudness Compressor

The APU Loudness Compressor is a complete loudness solution that combines dynamic range control with a built-in True Peak limiter. This allows you to achieve the Amazon Music target by increasing density and "glue" rather than just chopping off peaks.

Workflow:
1. Load the Mastering - Amazon Music Reference (Stereo) preset from the Purpose category.
2. To have the compression range follow your material, use Source Range Learn while playing the complete program.
3. Make any remaining compression and target-range adjustments. Hold Ctrl (Cmd on Mac) while dragging the middle of the target range to expand or contract it around the center.
4. Once the rest of the setup is finalized, enable Compensation Learn in the Limiter tab and play the complete program from start to finish. Turn Learn off when playback finishes to lock the final pre-limiter gain correction.

Guide: Loudness Limiter

For direct loudness and peak containment, the APU Loudness Limiter can be used as a standalone maximizing solution. It simultaneously targets the Amazon Music LUFS loudness and True Peak references.

Load the Mastering - Amazon Music Reference Ceiling (Stereo) preset from the Purpose category. It configures the loudness and True Peak ceilings for this target.

Soften up the limiter some more by switching to Short term loudness mode for a slower, more musical response. Short term is based on a 3 second average and is less sensitive to transient spikes, making it ideal for transparent music mastering.

Once the other settings are finalized, enable Compensation Learn and play the complete program from start to finish. Turn Learn off when playback finishes to lock the final correction. Run Learn again after any further processing changes.

Guide: Dynamics Optimizer

If you prefer an automated, offline approach, the APU Dynamics Optimizer analyzes your entire audio file and applies optimal normalization and limiting to meet the Amazon Music target in one pass.

Because it can see the entire file before processing, the Optimizer can calculate the gain adjustments needed while preserving the dynamics of the original material. Load the Mastering - Amazon Music Reference (Stereo) preset from the Purpose category, open the complete file, then analyze and optimize it. Review the result, then measure the exported file before delivery.

Metering for Amazon Music

Measure complete-track Integrated LUFS and linked Maximum True Peak. Retain the -2 dBTP working ceiling for codec headroom, and verify any platform-specific deliverable requirements separately.

Load the QC - Amazon Music Reference (Stereo) preset from the Purpose category. It configures the target range, True Peak threshold, Short-term history, and Integrated output for this reference.

Short-term loudness is useful for seeing how individual sections move, while Integrated loudness shows where the complete program finishes. The APU Loudness Meter provides real-time feedback on your audio's loudness levels, allowing you to make informed adjustments during the mastering process.

The statistics panel gives quick access to Integrated LUFS, LRA, and other useful measurements.
