GAINSYNC

Loudness matching tool for DJs
Hey DJs – imagine perfectly balanced sets. No more touching the gain knobs, ever. That's what GainSync is all about, letting you choose how loud your drops should be and matching every track to that level.
Want to push your tracks even harder? Add extra loudness with controlled analog style saturation, without redlining your mixer.
But how does this work? GainSync uses a smart algorithm that analyzes the track's structure and measures loudness using LUFS, a unit designed to reflect how our ears perceive sound.
GainSync can also detect fake bitrates and export your tracks in CDJ-compatible formats.
Try it free for 14 days – no registration needed. Full version is only 14.99€.

FAQ

Why is GainSync better than autogain in my DJ software

Most DJ software autogain features only look at the average loudness of the entire track using RMS. RMS doesn't account for how loud a track actually sounds to our ears, and averaging the whole track can be misleading too. A track with long quiet sections can end up with much louder drops than a more consistently loud track.

GainSync takes a different approach and focuses on the drops and loudest parts of each track. It measures their loudness using LUFS, which is designed to better reflect perceived loudness, so the parts that matter most when mixing stay at consistent levels.


How does GainSync work?

GainSync analyzes the structure of each track to find its drops and loudest parts. It then measures their loudness using LUFS, a standard designed to reflect how our ears perceive sound.

Based on this, GainSync adjusts each track to your chosen target loudness, so your drops hit at the level you want across your whole collection.


How loud can I push my tracks?

GainSync uses analog-style saturation instead of simply limiting or clipping the signal, so you can push your tracks louder while keeping the sound natural and musical. A saturation indicator shows you how hard you're pushing each track. It stays white when there's no saturation, then gradually goes from yellow to red as you push it harder. This way, you can get your tracks as loud as you need without constantly pushing your mixer into the red.


Can GainSync be used with any DJ software?

Yes, just make sure to disable any auto-gain feature in your DJ software, as it may interfere with the levels already adjusted by GainSync. Once that's done, you can set your gain knobs to the same position and forget about them, as long as you're playing tracks normalized by GainSync.


Can I use GainSync to normalize playlist already exported to my USB Drive?

Yes, just click the “Sync Tracks on Flash Drive” button, choose your drive, and you're good to go. GainSync will apply level adjustments directly to the existing files, so your playlist is fully gain-synced and ready for the club.


How does GainSync detect fake bitrates?

GainSync analyzes the track's frequency spectrum and detects the sharp cutoff characteristic of lossy encoding. This allows it to estimate the actual bitrate and identify tracks that have been transcoded to a higher bitrate without gaining any real audio quality.


What audio formats are compatible with GainSync?

GainSync supports WAV, MP3, FLAC & OGG files, and lets you choose your preferred export format while preserving your track metadata. It can also convert 24-bit and 32-bit WAV files to 16-bit for CDJ compatibility.
