The names must make sense, and every track must start together. Drop the folder into UTUVO Prep. Its built-in cleanup preset brings one hundred fifty-two editable rules, so name suggestions appear immediately. Accept, reject, or edit every proposal. If a file still says Audio zero seven, press Listen, hear the stem, and type the instrument. Prep does not guess. Then check the set itself. Every offset is shown in samples. Here, one stem is one hundred samples late, about two milliseconds. Two questions, then it is done: names, and heads.


Heads, checked
Every offset is a number you can act on.
Prep shows each track head in samples and seconds. The 48,100 sample row is 100 samples later than 48,000, about 2.08 ms at 48 kHz. Choose aligned corrected copies when the delivery needs one common head.


Names you can argue with
152 rules. Accept, reject, or edit each proposal.
The built-in Cleanup preset proposes names, but it does not guess for you. Listen to an ambiguous stem such as Audio 07, then type the instrument yourself.


Never touches your source
The correction is a new copy, not a surprise rewrite.
When you choose the alignment fix, Prep adds the exact leading silence needed for a common head, preserves the original audio samples, and writes corrected copies into an output folder. The source stays untouched.

What Prep does not claim
Precision is part of the product.
- No Logic, ADM / Dolby, by-example learning or cross-vendor substitution claim.
- No guessing: an ambiguous file such as Audio 07 needs a Listen step and your name.
- No whole-session repair, every-defect detection, release, price or download status claim.

Questions with bounded answers.
Does Prep guess an ambiguous stem name?
No. Press Listen, hear the file, and type the instrument yourself. Every proposal can also be accepted, rejected or edited.
What does the 48,100 sample value mean?
It is 100 samples later than 48,000. At 48 kHz that difference is about 2.08 ms, so the offset is visible instead of being left to a listen.
Does Prep change the source?
No. Corrections are written as new copies in an output folder. The original samples remain in the source files.
