Companion to https://diffio.ai/best-ai-audio-cleaners/

Use this worksheet with any audio cleaner. No email or account is needed
to keep this checklist. Diffio publishes it and sells one of the tools
in the guide. It is an evaluation aid, not a product quality score.

1. PICK ONE REPRESENTATIVE PASSAGE
[ ] Keep an untouched copy of the original recording.
[ ] Include a quiet phrase, a loud phrase, and the worst noise or echo.
[ ] Use exactly the same passage in every tool.
[ ] Note the model, settings, file format, and processing date.

Recording / passage: _________________________
Tool / plan / model: _________________________
Settings / date: _____________________________

2. LISTEN AT A SIMILAR VOLUME
[ ] Are the words easier to follow?
[ ] Do quiet words and sentence endings remain intact?
[ ] Does the speaker still sound like themselves?
[ ] Are there metallic, watery, or other distracting artifacts?
[ ] Is desired ambience or music still present?
[ ] If the tool cuts pauses or fillers, does the conversation still flow?
[ ] Recheck anything whose wording was uncertain in the original.

What improved: _______________________________
What got worse or remains uncertain: _________
Needs a human edit: __________________________

3. CHECK THE WHOLE WORKFLOW
[ ] Confirm supported format, file size, duration, and video support.
[ ] Confirm whether the free offer is a preview, trial, or export.
[ ] Check for branding or jingles on the output.
[ ] Check full playback, download, and export access on your chosen plan.
[ ] Open an exported file in the editor or player you actually use.
[ ] Compare monthly hours with your workload; account for daily caps.
[ ] Check tax, billing period, credit expiry, and rollover terms.
[ ] If automating, check API access and any separate API billing.
[ ] Review the provider's upload, storage, and deletion terms for your material.

Expected monthly hours / cost: _______________
Export or integration issues: ________________
Decision and reason: _________________________

Keep the original. Listen to the full result before publishing.
Do not treat processing as proof of words that were missing or uncertain.
