/ Method
How we assess sound.
This describes how I listen and what I measure while listening. It is a method, not a set of published test results.
/ The method
Compare at equal playback level
Both versions are levelled to the same integrated loudness before anything is judged. Louder is not better, it is just louder.
Listen for low end and transient shape
Definition in the bottom octaves, and whether the hit still arrives intact after processing.
Inspect stereo image and delivery levels
Width and mono behaviour, then integrated loudness and true peak against the target for the release format.

/ The mastering example
The example runs on your own track.
There is no public demo file here. Send one track and you get a free 60-second test master plus the measured audit in your account, where premaster and master are compared at the same playback level. Nothing is published, and nothing is charged before you have heard it.
Send a track/ Genre coverage
The same listening and measurement routine is used across the genres below. Every record is judged on its own terms, against released masters in its own genre.
LEARN is not AI.
LEARN measures your track on your machine — level, spectrum, groove — and sets the instrument from what it finds. It runs inside the plugin, on the record you loaded. No cloud, no model trained on other people's records.
What it gives you is a measured starting point. Every setting stays adjustable, and the final call is yours.
