Professional metering, AI analysis, and reference comparison — in your browser and your DAW.
Loudness Metering
EBU R128 compliant — momentary, short-term, integrated LUFS, and loudness range. K-weighted with proper gating. Full track averages, not snapshots.
True Peak & Levels
4x oversampled true peak detection alongside RMS, peak, crest factor, and DC offset. Know exactly where your headroom sits before bouncing.
Stereo Analysis
Real-time stereo width, correlation, vectorscope, and mid/side balance. Catch phase issues and mono compatibility problems before they reach the listener.
AI Mix Feedback
The AI reads every meter and gives you specific, actionable advice tailored to your genre. Ask follow-ups, request plugin chains with exact settings, go as deep as you want.
Stem Analysis
Switch to Vocals, Drums, Bass, or Instruments mode. The AI adjusts what it focuses on — sibilance for vocals, transient punch for drums, mono compatibility for bass.
New
Reference Tracks
Drop a commercial track as a reference. EchoJay analyses it locally and stores the results — LUFS, EQ curve, stereo image — so you can compare your mix against the pros.
New
AI Compare
Select your mixes and references side by side, then hit AI Compare. The AI gives a detailed breakdown of how your tracks measure up — works with full albums too.
New
EQ Curves
8-band average spectrum analysis rendered as a smooth EQ curve in Compare Mixes. See at a glance where your mix differs from the reference — sub through air.
New
Revision Tracking
Drop V2 after V1 and EchoJay detects it automatically. Keeps the chat together and compares exactly what changed between versions. Track your progress.
Audio Playback
Replay any reviewed track with waveform scrubbing. Audio is stored server-side for Pro users — access your mix history from any device, any browser.
Pro
Plugin Chains
Add your plugins in Settings. When you ask for processing advice, the AI builds custom chains using only your plugins — with exact Hz, dB, ms, and ratio settings.
Personalised Setup
Tell EchoJay your monitoring setup, room treatment, plugins, and workflow preferences. The AI tailors every response to your actual environment.
New
Client Mix Notes
Add client briefs and revision notes after analysing. The AI factors in what your client asked for — not just what the numbers say.
New
30+ Genres
Hip-hop, drill, trap, pop, R&B, EDM, house, rock, jazz, classical, lo-fi, afrobeat, phonk, jersey club — the AI knows what good sounds like in your lane.
Particle Visualiser
Audio-reactive OpenGL particle system with multiple presets — Orb, Helix, Ring, Nebula, and more. Six colour themes. Beautiful and informative at the same time.
Plugin
A/B Reference Playback
Load any WAV reference and play it through the plugin output. Smooth waveform scrubbing, play/pause from any view, spacebar control. Meters and spectrum react to the reference audio.
Plugin
Real-Time Spectrum
Smooth filled spectrum curve with Catmull-Rom interpolation, peak hold envelope, and log-frequency axis. A/B overlay fades when switching between your mix and reference.
Plugin
Channel Detection
The AI checks if your meter data matches the selected channel type. Route a full mix through "Lead Vocal" and it'll call it out — no wasted feedback on the wrong signal.
