Under the hood

What's inside the chain

Every master goes through all 14 steps, in order. No shortcuts, no skipped stages.

01

Validation & format check

Rejects already-mastered files. Checks sample rate, bit depth, clipping.

02

Gain staging

Headroom set to −6 dBFS to give every subsequent stage room to work.

03

DC offset removal + high-pass filter

Removes DC bias and subsonic rumble below 20Hz.

04

Spectral matching

Matches your track's spectral envelope to genre reference curves.

05

Corrective EQ

Uses Mixtus RTA data to address frequency-specific problems found in the mix.

06

Bus compression

VCA RMS compressor, genre-tuned ratio. Maximum 3 dB gain reduction.

07

Dynamic EQ

Genre-tuned frequency bands that only act when a threshold is crossed.

08

M/S widening + mono bass

Expands stereo width in mid-high frequencies. Bass below 120Hz stays mono.

09

Tape emulation

Adds harmonic warmth and a gentle HF rolloff for analogue-style character.

10

Sweetening EQ

Final genre-specific shelves and presence bumps for the target sound.

11

True peak limiter

4× oversampled limiting. No inter-sample peaks above −1 dBTP.

12

Loudness normalisation

pyloudnorm measures and normalises integrated LUFS to platform target.

13–14

4-format encoding

Simultaneous export: 24-bit WAV · OGG Vorbis · AAC · MP3 320.

18 genre profiles

Tuned to your genre

NITOR isn't one-size-fits-all. It ships with 18 genre reference profiles — each with different spectral targets, compression ratios, and EQ curves.

FAQ

Questions

What should I upload — a mix or a pre-master? +
Upload your final mix exported at 0 dBFS or slightly below — ideally −3 to −6 dBFS peak. NITOR handles everything from there. Don't upload a file that's already been mastered.
How long does mastering take? +
Processing typically takes 2–4 minutes. Cold start on the first job of the day may add 30–60 seconds.
What if I don't know the genre? +
Just type what comes to mind — 'like Radiohead but warmer', 'blues-rock', 'dark techno'. NITOR reconciles free-text to the nearest genre profile.
Can I use the files commercially? +
Yes. You own the output files fully. No royalties, no attribution required.
Is there a subscription? +
Not required. Buy credits when you need them — they never expire. Pro subscription available if you master frequently.
