MixLab Analyzer
Upload or record a clip. Get readable metrics — dynamics, brightness, stereo width, low-end density, harshness risk — plus plain-language feedback cards.
Everything runs client-side. Your audio never leaves the browser.
How this is measured 01.b Also in MixLab · stem compare
Stem compare
The right tool when you’re A/B-ing two versions of the same stem — original vs processed, take 4 vs take 5, before-and-after a plugin. Instant-switch playback that keeps the playhead position, plus a side-by-side delta table.
Drop two stems. Toggle while playing. Trust your ears for the verdict; trust the deltas for the explanation.
02 Use cases
Reference comparison
Drop your track and a reference side by side. See the deltas in plain language, not Pultec marketing copy.
Stem QA before delivery
Catch phase issues, clipping, and odd centre-heaviness before you send stems to the next person in the chain.
03 What makes it different
MixLab doesn’t try to "enhance" your mix. It gives you readable numbers and language you can act on — the same kind of feedback a senior engineer would type into a Slack DM after listening once.

06 FAQ
Does my audio get uploaded?
No. All analysis runs in your browser via the WebAudio API. The file never leaves your machine.
Will this replace my mixing engineer?
No, and that’s not the goal. It’s a sanity check, not a verdict. Engineers exist for a reason.

Where this leads.
VoiceLab
Run voice QA on the same file
If your master contains voice, push it to VoiceLab for sibilance, noise-floor, and intelligibility scoring.
HearLab
Test against assisted listening
See how the mix lands for users on hearing aids or with elevated noise floors via the HearLab companion.
SignalLab
Index music vs speech regions
Send the same file to SignalLab and get a labelled timeline of voice, music, silence, and noise regions.
CueLab
Place it in a broadcast routing
Use CueLab to plan how the mastered programme moves through hosts, guests, stream, and recording.
SkillLab
Train your ears to hear it
SkillLab drills the exact perceptual skills (LUFS, crest factor, brightness) the analyzer just measured for you.
Each lab can hand audio off to the others without re-uploading. When you finish an analysis here, the → Lab buttons in the demo chrome carry your audio directly into the next lab’s analysis flow.
