How it works
A professional analysis system
for finished masters.
LoopBounce evaluates a finished master through a structured technical framework. It does not generate, process, or automatically master audio — it examines your track across loudness, dynamics, tonal balance, stereo image, and phase behavior, then returns clear feedback to guide revision and decision-making.
The distinction
Not mastering. Analysis.
What LoopBounce is not
- An AI mastering engine
- An automatic audio enhancer
- A one-click fixer
- A replacement for artistic judgment
What LoopBounce is
- A structured analysis framework
- A decision-support layer
- A second opinion, grounded in reference data
- A way to identify strengths, risks, and revision priorities
The analysis reads the master. It does not rewrite it. Every creative decision stays with you.
What it analyzes
Five dimensions of a finished master.
Every master is evaluated across the same five technical dimensions — the same framework real mastering engineers use when reviewing a release.
Loudness discipline
Integrated LUFS, true peak, and headroom evaluated against club delivery standards — not streaming averages.
Dynamic integrity
LRA, crest factor, and transient preservation — checking that the master still breathes without being crushed.
Tonal control
Spectrum shape across six frequency bands, compared to a calibrated genre envelope to flag recessions or build-ups.
Stereo image
Width, balance, and side-signal energy across the frequency range — so the mix translates from headphones to a PA.
Phase coherence
Correlation across frequency bands and worst-moment detection — mono compatibility for every playback system.
Global stability
All five dimensions feed a single Quality Score — a calibrated reference-suitability measurement rather than a subjective rating.
How the analysis works
From audio to structured feedback.
The pipeline is deterministic, reproducible, and mastering-engineer readable. No generative layer, no black box.
Measure
Every audio file is decoded and passed through measurement modules — loudness (EBU R128), dynamics (LRA, crest factor, RMS), spectrum analysis (FFT across the full song), stereo width, and per-band phase coherence.
Compare
Raw measurements are compared to a calibrated reference model — a curated envelope built from real-world club music masters across techno, melodic techno, and dark electronic genres.
Interpret
Cross-factor rules translate measurements into findings — sub recession tied to spectrum data, phase exposure linked to worst-moment timestamps, loudness flagged against club-delivery standards.
Report
The interpretation becomes a structured report — a Quality Score, per-dimension breakdown, a tonal envelope chart, strengths, risks, and actionable revision guidance written in mastering-engineer language.
The reference model
Calibrated against real club masters.
A number means nothing without context. LoopBounce evaluates every master against a curated reference envelope — built from real, approved club music masters across techno, melodic techno, and dark electronic genres.
This is not a streaming-loudness target or a generic EQ curve. It's a multidimensional envelope that captures how professional club masters actually behave — their loudness ceiling, their spectrum shape, their dynamic headroom, their stereo behavior.
When your master is analyzed, the system evaluates whether each dimension sits within, above, or outside the expected range. That's where the feedback comes from — not from arbitrary thresholds, but from how your track compares to the real world.
Tonal envelope
Your master vs. genre reference
What you receive
A structured report you can act on.
Quality Score
A calibrated 0–100 reference-suitability score, broken down across five weighted dimensions.
Technical metrics
LUFS, True Peak, LRA, Crest Factor, RMS, Peak, Balance — each classified against club-delivery targets.
Tonal report
Full-track spectrum analyzer with peak overlay, per-band frequency deltas vs. the genre target curve.
Stereo coherence review
Phase behavior across frequency bands, with worst-moment timestamps and mono-compatibility assessment.
Strengths & risks
Structured written findings — what's working, what to review, and why it matters for the release.
Revision guidance
Optional plugin-specific suggestions (e.g., iZotope Ozone module recommendations) that stay out of the way until requested.
Who it's for
Built for people who ship music.
Mastering engineers
A calibrated second opinion before approving a final master. Catch an overlooked sub recession or a phase issue before the label does.
Producers & artists
Compare revisions side-by-side with objective data. Know whether the version you're about to send is actually better than the one before it.
Labels & A&Rs
Review incoming masters against a reference framework built from real club music. Make technical go/no-go decisions with confidence.
