Two apps. One ecosystem. All in your browser.

Bridging the gap for AI-generated music.

Latent makes the tools that fix, finish, and remix music that came out of a generator. Two apps, one ecosystem, all running in your browser — your audio never leaves your machine.

Both apps are free. No account, no credit card, no catch.

The Latent idea

AI-generated music has known failure modes — harshness, brickwall cutoffs, phase issues, clipping, fake sample rates — that generic mastering tools don't address. AI Music generator exports come as one stereo file you can't remix, rebalance, or isolate parts from.

Latent builds tools purpose-made for these specific problems, running client-side for privacy. Not generic audio software with an "AI" sticker slapped on — built from the ground up for the way AI-generated music actually sounds, and the way people who make it actually work.

Which tool do I need?

Both are free, both run in your browser, and your audio never leaves your machine. Pick the one that matches what you're trying to do.

Mastering

Latent Mastering

You have a finished track and want it to sound right.

For: a Suno or Udio export that sounds harsh, thin, or clipped, and you want it to sit next to a real release.

On-load Analyzer flags what's actually wrong — harshness, cutoffs, phase, clipping — with one-click fixes
Repair suite: de-click, de-clip, de-noise damaged or lossy source material
Reference A/B + EQ Match: loudness-matched, nudge your tone toward a track you like
Full metering: LUFS, true-peak, stereo correlation, spectrum, spectrogram, vectorscope
Codec preview: hear your master after Opus/AAC compression, before you ship it
Real-time chain: glue comp, de-harsh, stereo imaging, exciter, soft clip, true-peak limiter

Mixing

Latent Mixer

You have one stereo file (or stems) and want to remix, isolate, or rebalance.

For: a whole-track export you want to split into stems, rebalance, or pull an acapella / instrumental out of.

In-browser stem separation on your own GPU via WebGPU — no uploads, no per-minute charges
Pre-split or whole-track: drop one file and Latent splits it, or load 2–8 stems you already have
Per-stem mixing: fader, pan, mute, solo, plus EQ5, glue comp, and limiter on every track
Honesty features: null-check badge proves your stems reconstruct the original
One-click derived exports: instrumental and acapella are exact, because mixing is linear
Built for AI-music people, not audio engineers — sensible defaults on every module

Explore Latent Mixer

Use both: start in Mixer to split and rebalance, send the result to Mastering to finish. One ecosystem, one workflow.

What makes Latent different

Four things that are true across both apps — the Latent DNA.

Purpose-built for AI music

Not generic audio tools with an AI label. Built from the ground up for the known failure modes of Suno, Udio, and ACE-Step output.

Private by design

Everything runs client-side. Separation on your GPU, mastering in your browser — your audio never leaves your machine.

Honest by default

Null-checks that prove separation didn't eat your track. Level-matched A/B so you judge the mix, not the volume. Real metering, not vibes.

Pro-grade DSP, made simple

Toggle-first modules with sensible defaults on by default. A user who touches nothing still gets a clean, streaming-compliant result.

Frequently asked

Is my audio uploaded anywhere?

No. Both apps run entirely in your browser. Stem separation happens on your own GPU via WebGPU; mastering happens in your browser via WebAssembly. A server only serves the static site files — your audio never touches it.

What browsers and hardware do I need?

Latent Mastering works in any modern browser that supports WebAssembly SIMD (Chrome, Edge, Firefox). Latent Mixer's stem separation needs a WebGPU-capable browser — Chrome or Edge recommended. Firefox and Safari don't yet ship WebGPU everywhere; the app will tell you exactly what's needed rather than silently failing.

What audio formats does it accept?

Both apps accept anything your browser can decode — MP3, WAV, FLAC, and OGG. Drop a file in and it works. Exports are WAV (16, 24, or 32-bit float) for now; FLAC and MP3 export are coming in a later phase.

Is it really free?

Yes, both apps are free to use with no cap or limits. No account, no credit card, no per-minute charges, no song credits. A paid desktop app (for power users) is planned for later, but the web apps stay free.

Do I need to install anything?

No — both apps run in your browser at app.latentmastering.com and app.latentmixer.com. A native desktop app (Windows, macOS, Linux) is planned for later, with native-GPU speed.

What's coming next?

Mix Assistant (analyzes stems and suggests a starting balance), 6-stem separation (adds piano and guitar), batch and album mode, FLAC and MP3 export, and the desktop apps. The Mix → Master pipeline hand-off between the two apps is also being tightened up.

I make music with AI generators. Which should I use first?

If you have one finished track that needs to sound right, start with Latent Mastering. If you have one stereo file and want to pull it apart, rebalance, or isolate parts, start with Latent Mixer. Many people use both: split and rebalance in Mixer, then send the result to Mastering to finish.
