LAVELT
One target.
Every clip checked.
Match the loudness of short audio files with shared-channel constant gain. Keep the real source and result values beside each file, then save matched WAVs and their measurements.

Keep the batch in view.
Choose a common target or use a measured clip as reference. Include the files you need. On a tablet, keep the batch beside the current clip’s actual waveform and source/result listening controls.

See where peaks constrain the match.
A sample peak ceiling can prevent a clip from reaching the loudness target. Lavelt labels that outcome, remeasures the written WAV and keeps the result available for inspection.

Matched audio, plus the record.
Save the included current matched WAVs with Measurements.csv, Settings.json and Readme.txt in a ZIP. Output is 48 kHz, 32-bit float WAV. This is an output bundle, not an editable project backup. Keep original files and metadata separately.
