Features

Everything your master needs

Aumixys technology combines classic audio engineering with modern spectral analysis and AI.

🎧
LUFS & Loudness
Integrated, Short-term and Momentary LUFS with loudness histogram. Check if your track passes Spotify normalization.
📈
True Peak (ISP)
Oversampled peaks with clipping position detection. Safe -1.0 dBTP ceiling — the streaming standard.
🌈
Spectrogram & Heatmap
Full frequency spectrum with band splitting and interactive heatmap. Detect missing or excessive octaves.
🔊
Stereo Analysis
L/R correlation, stereo width, Mid/Side balance and phase goniometer. Ensure your mix doesn't disappear in mono.
⚡
Dynamics & Crest Factor
DR Meter, Crest Factor, RMS vs Peak over time. Assess if your mastering breathes — or if it's too squashed.
🤖
AI Tips & Auto QC
Automatic tips based on analysis. Quality control with report: clipping, phase, DC offset, silence, transcode.
🔁
A/B Comparison
Intelligent listening with gain matching and EBU R128 normalization. Compare versions without volume cheat.
📚
Batch (Album)
Consistency analysis of the entire album. LUFS comparison, streaming compliance, batch quality control.
🎹
Key & Tempo
Automatic key and BPM detection. Chroma profile and tempo over time — including live recordings.

Knowledge Base

Audio analysis standards for mastering

Educational section for producers and engineers. We explain Audio Normalization Standards, Loudness Penalty, True Peak, Stereo Image Analysis and Phase Correlation.

1) LUFS and Loudness Penalty
Streaming platforms use loudness normalization. If a track is too loud, Loudness Penalty is applied and the platform turns it down. High LUFS alone is not an advantage and often damages dynamics.
2) True Peak vs Sample Peak
Sample Peak is not enough. After codec conversion, inter-sample peaks (ISP) may appear and clip even when a mix looked safe. True Peak helps estimate real clipping risk after transcoding.
3) Stereo Image Analysis and Phase Correlation
A wide stereo image sounds impressive, but poor phase correlation can collapse energy in mono playback. Stereo Image Analysis and Phase Correlation help balance width, mono compatibility and vocal clarity.

FAQ: mastering and technical quality

Is -14 LUFS always the target?

Not always. -14 LUFS is a common reference, but genre, arrangement and production aesthetics matter. What matters most is the relationship between Integrated LUFS, Short-Term LUFS, True Peak and dynamics.

Why use dithering during export?

Dithering reduces quantization distortion when reducing bit depth (for example 24-bit to 16-bit). When used correctly, it preserves low-level detail and improves final master quality.

How should you read Audio Normalization Standards?

Treat standards as a set of technical constraints: target loudness, True Peak ceiling, stereo stability and no clipping. The best result is a master that passes quality checks and translates across playback systems.

Why Aumixys

Analysis that translates into better releases

Aumixys is not just another meter. It is a practical decision tool for producers, mixing engineers and mastering engineers. Instead of guessing what to fix before release, you get a clear picture: where the track is too loud, where it loses dynamics, whether stereo stays stable and whether transcoding can introduce artifacts.

Pre-release workflow
Late fixes are the most expensive part of mastering. Aumixys shortens that decision loop: upload a file, get a full report, and immediately see if the material is ready for Spotify, YouTube and Apple Music. In practice this means fewer iterations, less blind trial-and-error and faster project closure. It matters even more for EPs and albums where consistency across tracks defines the quality of the full release.
Engineering language, not guessing
LUFS, True Peak, Phase Correlation, dynamics, spectrum and clipping control are technical signals that directly affect streaming translation. Aumixys combines those metrics into one coherent analysis, so instead of scattered numbers you get one clear context. This makes it easier to decide whether you need limiter tuning, tonal balance changes, transient control or stereo width correction.
A/B comparison without loudness bias
Our hearing naturally prefers the louder version even when it is objectively worse. That is why A/B in Aumixys uses gain matching and normalization for fair comparison. You can reliably check differences between master versions, between your track and a reference, or between revisions after client feedback. This saves time and reduces wrong decisions driven by loudness bias.
Who is this for?
For independent producers who want more confidence at release time. For mixing engineers who need a fast sanity check before delivery. For mastering engineers who want faster technical diagnostics and consistent quality standards. For labels and A&R teams comparing multiple versions with a repeatable, measurable audio evaluation process.
