A mastering report for every master
Automatic mastering usually hands you a louder file and asks you to trust it. Echoteka measures your track before and after and shows the numbers — and says so when a target was not reached.
What the report measures
| Measure | What it tells you |
|---|---|
| Integrated loudness, LUFS | How loud the whole track is, the way streaming services measure it |
| True peak, dBTP | Whether the master leaves headroom for MP3 and AAC encoders |
| Loudness range, LU | How much the level moves between quiet and loud parts |
| Crest factor, dB | How much punch the peaks keep above the average level |
| Stereo correlation | How wide the mix is, and whether it stays safe in mono |
Each value is shown for your upload and for the master, side by side.
When a target is not reached
Sometimes the honest answer is to stop short. If pushing a track to the loudness you chose would crush dynamics that are already at the limit, Echoteka stops earlier and tells you where and why — for example, that it stopped at −11 LUFS instead of −9. You decide what to do next, with the numbers in front of you.
Compare by ear, fairly
Louder always sounds better at first. The before/after player matches the loudness of the two versions, so you compare the sound, not the volume. If your device cannot match them, the player tells you by how many decibels one is louder.
Share it
The before → after result can be saved as an image and sent to a collaborator, a label or a distributor, or posted with the track.
Why a report matters for AI and home-made tracks
Generated and self-mixed tracks vary a lot. A report shows whether artifact cleanup and mastering kept the character of the track or flattened it — which is the question you would otherwise have to answer by ear, on one pair of speakers.
Is the report included in every master?
Yes. It comes with every master at no extra cost, including the free ones.
Can I see the numbers before paying?
Yes. The free analysis measures loudness, true peak, dynamics and stereo of your upload without an account.
What loudness should I aim for?
For streaming, about −14 LUFS with true peak under −1 dBTP is a safe default. See Spotify loudness explained.
What if I do not like the result?
Try another genre profile or a reference track and compare the runs. A failed master returns the credit automatically.
