How TrackGleam masters your music
TrackGleam doesn't run a one-size preset. It measures your track right in the browser — loudness, true peak, dynamics, an 8-band tonal balance, stereo width, and artifact patterns — then compares those numbers against genre-calibrated targets tuned to how music in your style is finished. The AI reads the gap and writes a mastering recipe for your song, with a plain-English reason for every move. Everything happens on your device; only the numbers behind an optional AI version are ever sent anywhere.
Then it does what a mastering engineer does: it checks its own work. The engine re-measures the master it just made, sees how far it landed from the target, and corrects — a closed loop that repeats until the tonal balance and loudness lock in, not a single blind pass. That's the Gleam Engine V2: a 14-stage chain, tuned to what your track actually needs.
🎯 Reference Mastering — trained on the song you pick
Big-name AI masters are “trained on millions of songs” you'll never hear or choose. TrackGleam flips that: drop in the exact commercial track you want to sound like, and the engine matches its tonal signature with a linear-phase filter. Your reference, your call — and you can hear the match against the original.
Measured, not magic. Every number the engine shows is real and yours to verify — run the finished master through any LUFS meter and the readings match. No black box, no mystery dataset.
See the complete 14-stage chain
The full chain: input conditioning, 8-band parametric EQ, dynamic EQ, 3-band multiband compression, parallel glue compression, upward density, stereo image processing, 3-band multiband saturation, harmonic exciter, brickwall limiting, mid/side EQ, transient shaping, de-harsh, and TPDF dithering — all configured automatically for your specific track, right in your browser.

How the Free Tiers Actually Compare
Looking for a free LANDR alternative? TrackGleam masters your song in the browser at no cost, with no account and no upload — unlike LANDR, Waves, and eMastered, which gate downloads behind subscriptions or per-track fees. You get a watermark-free −14 LUFS master to download instantly, plus an optional $1.99 AI master.
Checked July 2026 — full details on the LANDR comparison and alternatives roundup pages.

FAQ
Does TrackGleam upload my audio?
No. Your audio file is decoded and processed inside your browser, on your own device — it is never uploaded to a server. For the optional AI version, only numeric measurements (loudness, tone balance, stereo profile) are sent; the audio itself never leaves your device.
Can I really download the master for free?
Yes. The full mastering tool is free with no account and no signup, and free masters have no watermark. You can download the mastered file as a WAV or MP3 at no cost, as many times as you like.
What loudness does TrackGleam target?
Auto (Streaming Ready) mode targets -14 LUFS integrated loudness with a -1.0 dBTP true-peak ceiling — TrackGleam's streaming-safe starting point, not a universal requirement. You can change it with the Intensity control, from -16 LUFS up to about -11 LUFS.
Can I use the result on Spotify or Apple Music?
Yes. The default -14 LUFS, -1.0 dBTP master is a safe target for Spotify, Apple Music, YouTube, Tidal, and Amazon Music, which normalize loud tracks down to a similar level. Apple Music references about -16 LUFS, which the Low intensity setting matches.
What does the optional AI version change?
The optional AI-tuned version makes track-specific EQ, compression, loudness, and stereo decisions on top of your free master. It is a different take, not automatically better — you can preview the full result free, then pay $1.99 once to remove the watermark and download. The free master is always yours to keep.
Can TrackGleam improve Suno or Udio tracks?
Often, yes. The AI Fix presets can reduce the metallic shimmer, brittle highs, harsh upper-mids, and unstable stereo common in AI-generated music using subtractive EQ, tighter high-band control, and safer stereo handling. They cannot fully reconstruct audio that is already damaged.
Which formats are supported?
TrackGleam accepts MP3 and WAV files as input, and exports your master as a WAV (16, 24, or 32-bit float) or an MP3 at 320 kbps.
How does TrackGleam compare with LANDR?
Same core craft — analysis, EQ, multiband compression, saturation, stereo processing, and limiting — but a different deal. As of July 2026, LANDR's free tier is a preview you cannot download, its cheapest single download is $10, and every master uploads your audio to its servers. TrackGleam's free master is a real watermark-free WAV with no account, processed entirely in your browser.
Featured learning guides
Short, original notes on getting a better master. Browse all guides →
Streaming loudness in plain English
Most streaming services turn loud songs down. That means a master that is simply louder is not automatically better. In practice, a controlled, clean, balanced master often survives normalization better than an over-limited one.
- Use Auto when you want a safer streaming target.
- Use louder genre presets when you want more density and energy.
- Watch true peak and harshness, not just overall loudness.
What AI cleanup can and cannot do
TrackGleam can often reduce brittle highs, unstable stereo, and metallic shimmer, but it cannot fully reconstruct damaged transients or replace a bad generation with a perfect recording. Think of AI Fix as artifact taming, not full restoration.
Why mono bass matters
Very wide bass can collapse badly on phones, club systems, or mono playback. TrackGleam can mono-sum the lows below a chosen point so the center stays punchy and more translation-friendly.
Why some masters look smaller after processing
A processed waveform is not always visually bigger. Corrective EQ, trimmed silence, safer true-peak control, and preserved dynamics can produce a waveform that looks less inflated while sounding more polished and more portable across playback systems.
How to prepare a mix before you master it
A mastering tool works best on a balanced mix with enough headroom. If your kick is distorting, your vocal is buried, or your stereo image is unstable, mastering can only polish those problems, not fully undo them. For best results, export a clean stereo mix, avoid clipping on the mix bus, leave obvious corrective moves to the mix stage, and use mastering for final tone, loudness, width, and delivery.
1. Leave headroom
TrackGleam can raise loudness safely, but it performs best when the source is not already crushed. A mix that peaks below 0 dBFS and still breathes usually masters better than one that is already slammed.
2. Fix the mix first
If the low end is wildly uneven or the snare is painfully harsh, correct that in the mix when possible. Mastering is strongest when it makes broad, musical finishing moves.
3. Pick the right preset
Use Auto for streaming-safe delivery, genre presets when you want more flavor, and AI Fix only when a track truly has brittle, metallic, unstable artifact patterns.
4. Trust your ears
The processed waveform and meters help, but your ears still matter most. Toggle between original and processed playback and watch for dullness, pumping, or over-bright tops.
