Lavelt Audio Match

Lavelt brings a batch of short audio files toward a common integrated loudness and exports real processed WAVs. Prepare soundboard cues, music excerpts or short editing assets without opening a full audio workstation.

MEASURE A BATCH Import up to 12 mono or stereo clips from Files. See gated integrated LUFS and sample peak, then choose a custom common target or use a measured clip as reference. Include or exclude individual files.

RENDER AND LISTEN Apply constant gain to new audio files. A sample-peak ceiling constrains that gain, preserving the waveform dynamics without compression. Clips that cannot reach the loudness target are clearly marked Peak limited. Every output is measured again after writing. Listen to the source or actual rendered result on repeat, at their real levels.

KEEP YOUR WORK Save and reopen up to 12 named batches with working audio copies, selected target and results. Save up to 20 named loudness/ceiling targets for reuse. Normal installs start empty; an optional original synthesized soundboard example makes the full workflow available without downloading files.

DELIVER THE FILES Build and share a ZIP of included, currently rendered WAVs, Measurements.csv, Settings.json and Readme.txt. The CSV includes source and actual result LUFS, applied gain, sample peak, target, ceiling and peak-limited status. iPad places the file batch beside a listen-and-inspect pane; iPhone opens an individual file inspector.

One upfront purchase covers all features. No subscription, in-app purchase, account, microphone permission, advertising, analytics, tracking, cloud service or developer upload.

SCOPE AND LIMITS Each source must be 50 MB or smaller and decode to 0.4 seconds–3 minutes. WAV, AIFF, M4A and MP3 depend on the system audio decoder; protected and multichannel audio are unsupported. Working copies and exports use 48 kHz, 32-bit float WAV. Integrated measurement uses mono/stereo K weighting with absolute and relative gates. Silence below the gate cannot be matched.

This is constant-gain loudness matching with a SAMPLE peak ceiling. It does not measure true peak, limit peaks, compress dynamics, remove noise or certify broadcast/streaming delivery. The LUFS target may remain unmet when peak headroom is insufficient. Turn playback volume down before comparing levels.

The local working library, including results and ZIPs, is limited to 400 MB; enough device space is also required for rendering. Original files, artwork and source metadata are not preserved in exports. Keep originals separately. A delivery ZIP is not an editable project backup. Device backups follow your system settings. Use audio you are authorized to process and share.
