Make sure your album or EP sounds cohesive from first track to last. Upload multiple tracks and the AI analyzes loudness levels, tonal balance, and dynamic range across the entire project. The report identifies outliers that might disrupt the listening experience and provides specific recommendations for mastering adjustments to achieve a unified, professional-sounding release.
Album inconsistency typically arises when individual tracks are mixed at different times or in different studios, use significantly different instrumentation or production styles, or are mastered to different loudness targets. A mastering engineer working on a project sequentially aims to achieve consistency, but when tracks are mixed by different engineers or recorded over an extended period, significant variations in tonal balance and loudness can persist even after mastering.
A variation of up to 2 LU (Loudness Units) between tracks in an album is generally imperceptible to most listeners. Variations of 3–4 LU may be noticeable on attentive listening but may be intentional for artistic effect (quieter ballads, louder bangers). Variations above 5 LU between consecutive tracks are typically jarring and suggest that mastering intervention is needed to bring the project to a cohesive level.
The tool works on any collection of tracks, whether it's a 2-track single package, a 5-track EP, or a 12-track album. It compares all uploaded tracks against each other and against the project average, identifying which tracks are outliers in terms of loudness, tonal balance, and dynamic range. The recommendations are then specific to bringing the outliers in line with the overall project character.
Both stages are valuable. Running the analysis before mastering gives your mastering engineer a reference report that identifies the specific consistency issues to address, saving time and making the brief more precise. Running it after mastering verifies that the engineer's work has successfully brought the tracks to a unified level and catches any remaining outliers before you submit to your distributor.
