Stop Mismatched Volumes and Corrupt Files From Killing Your DJ Sets.
APE Pro is a precision-engineered audio diagnostic and leveling engine that scans, normalizes, and repairs your music collection before it hits your USB or DJ deck.
- 🚨 Mismatched track volumes (Gain riding)
- ❌ Broken ID3 headers (CDJ lockups)
- 🔍 Hidden low-quality upscales (128kbps)
- ✅ Transparent R128 loudness matching
- ✅ Standardized ID3v2.3 tags & BPMs
- ✅ Verified club-ready high-bitrate files
A single bad file can cause playback problems at the worst time.
The "Emergency Loop" Disaster
Corrupt ID3 tags, junk metadata block bytes, and broken frame headers are invisible in Windows Explorer, but they can cause failed loads, playback glitches, or DJ software surprises when you need reliability most.
The Gain-Riding Nightmare
Constant manual channel adjustment is exhausting. One track is recorded hot; the next is quiet. APE Pro measures real perceived loudness (LUFS), applying a transparent gain offset by default so your mix stays level without heavy compression.
Fake "320kbps" Club Rips
Upscaled YouTube rips look like 320kbps files in your folder, but they sound hollow and muddy on a club system. APE Pro performs high-frequency spectral pre-flights to spot fake files instantly.
Level your tracks
Match perceived loudness across your set so one song does not leap out while the next disappears.
Scan and clean your library
Find risky MP3s, messy tags, duplicate files, and quality problems before they reach your USB or backing-track folder.
Transparent Loudness Correction. No Heavy Compression. Built to Preserve Dynamics.
Unlike amateur converters that squash your audio with harsh limiting, APE Pro uses measured volume normalisation mapped to your target LUFS, outputting consistent, club-ready files.
- Precision Gain Tuning: Applies one calculated gain offset across the track to match your LUFS target while avoiding pumping, limiting, and heavy dynamic compression.
- Clean Header Reconstruction: Rebuilds MP3 structures using lossless remuxing (`ffmpeg -codec copy`) to strip duplicate tags, bad framing, and junk metadata that lock up CDJs.
- VBR Beatgrid Drift Scan: Direct Xing, VBRI, and Info header checks flag variable bitrate encodings before they cause sync slips or drifting beatgrids in DJ software.
- Auto-Trim Trailing Silence: Safely clips dead air at the end of tracks for seamless mixing and instant cue response, without shifting the start transient or drifting Rekordbox beatgrids.
- Fail-Safe Sandbox Backups: Automatically clones tracks to local, timestamped `.ape-backups/` folders with full session manifests before performing any tag or frame operations.
Audiophile Standard
A lower loudness target for tracks where preserving dynamics matters.
Pro Streaming Standard
A common loudness target for general playback and streaming-style listening.
Club & Performance
A louder target for performance environments, with processing designed to reduce clipping risk.
What are LUFS?
LUFS (Loudness Units relative to Full Scale) is the modern industry standard for measuring perceived loudness. Unlike old-school peak metering, LUFS accounts for how the human ear actually hears sound, giving you a much more consistent mix between different tracks and genres.
Tracked & Reversible
APE Pro stores an APE history marker with the applied offset and target LUFS. If you need to undo a change, the app can apply an inverse gain to bring the track back close to its previous level.
Deep Health Scanning
Scans MP3 integrity, encoding quality, and structural health to help spot risky files.
