Use Matchering to match your track's loudness, EQ, and dynamics to any reference recording. Get the sound of your favorite masters.
Real-Time Visualizations
Waveform display, LUFS loudness meters, and 7-band spectrum analyzer with before/after comparison so you can see exactly what changed.
Batch Processing
Import multiple tracks and master them all in one go. Analyze All and Master All buttons process your entire album or EP in a single workflow.
Configurable Presets
Streaming, CD, Vinyl, and Loud presets with adjustable target LUFS, ceiling, and stereo width. Fine-tune every parameter to your needs.
CLI Tool
Full command-line interface for scriptable mastering workflows. Analyze, master, and batch-process files from your terminal or CI pipeline.
Workflow
Four Steps to a Professional Master
Import
Drag and drop your audio files or use the file picker. Import a single track or an entire album for batch processing. Supports WAV, AIFF, FLAC, MP3, OGG, and more via Symphonia decoding.
Analyze
One click runs full audio analysis — Integrated LUFS, Short-Term LUFS, RMS, Peak, True Peak, Dynamic Range, Stereo Width, and 7-band frequency analysis. Results appear instantly in the visualizer.
Master
Choose your backend — Matchering for reference-based mastering, AI for intelligent parameter generation, or Local ML. Select a preset (Streaming, CD, Vinyl, Loud) and click Master All. Watch the before/after comparison in real time.
Export
Mastered files are saved alongside your originals with a _mastered suffix. Compare waveforms, LUFS meters, and spectrum analyzers before and after to verify your master.
Use Cases
Built for Real Music Workflows
Music Production

Audio Analysis
Professional-Grade Audio Intelligence
Native Rust audio analysis engine that measures every dimension of your sound — before and after mastering.
LUFS Loudness
Integrated LUFS and Short-Term LUFS measurement per EBU R128. See exactly how loud your track is and how it compares to platform targets.
Dynamic Range
Measures the difference between the quietest and loudest parts of your track. Ensure your master has the right balance of impact and breathing room.
Stereo Width
Analyzes the spatial characteristics of your mix. See how wide your stereo image is and how mastering affects it.
7-Band Frequency Analysis
Sub-bass, bass, low-mid, mid, upper-mid, presence, and brilliance — see the spectral balance of your track visualized in the spectrum analyzer.
Non-Destructive
Your original files are never modified. Mastered versions are saved as new files with a _mastered suffix.
Scientific Precision
Rust-native DSP engine with Symphonia decoding. True Peak measurement, EBU R128 loudness gating, and before/after metric comparison.
