Analyse and master a mix in your browser.
Drop in a mix and get a straight answer: how loud it is against a streaming target, where it clips, whether it survives mono, and what to do about each. Then finish it through a 7-stage chain and measure the result rather than trusting it.
All of it runs on your own machine. The audio is decoded, processed and rendered in the browser — nothing is uploaded, and there is no queue to wait in.
What it measures
- Integrated loudness (LUFS)
- Measured to BS.1770, the same standard the streaming services use to decide how far to turn your record down.
- True peak (dBTP)
- Oversampled, so it catches the peaks that appear between your samples when a converter plays them back — the ones that clip on a phone but not in your DAW.
- Spectrum and tonal balance
- Where the energy actually sits, against the shape a finished record usually has.
- Phase and channel balance
- Whether the mix survives being folded to mono, and whether it's sitting off-centre without anyone noticing.
The chain
Seven stages, in the order the signal runs through them. Each one has a reference page explaining what it does and the one rule for using it — no account needed to read them.
- 01
ANCHOR
Gain staging, and riding a level
- 02
MAGEQ
Program EQ, and the boost-and-cut trick
- 03
LUMA-2A
Optical compression: the slow one
- 04
VELVET BUS
Bus compression, and where “glue” comes from
- 05
FERRIC-9
Tape saturation, and what people mean by “warm”
- 06
HALO
Stereo width, bass mono, and surviving a phone
- 07
ZENITH
True-peak limiting, and why −1 dBTP
The targets it masters to
Pick where the record is going and the chain aims at it. These are the numbers the processor uses.
- Streaming
- Club / loud
- Dynamic
- Reference / rough
