The mix is done and it still sounds like a rehearsal in a tiled room next to a record that already owns the genre. MasterShift is the Matchering-based mastering booth on The Altar: you upload a mix, optionally a reference, pick a deathcore-first preset or another genre lane, and get a louder, wider, more finished bounce. Knobs people actually use are loudness, brightness, punch, and width. Accept WAV, FLAC, or MP3. Recommend 24-bit WAV with about -6 dB of headroom. Files are deleted after six hours. This is not a mix engineer, not a replacement for arrangement, and not a magic fix for clipping drums you already slammed into the ceiling.
Matchering studies a reference and shapes your track toward that spectral and loudness neighborhood. Deathcore presets exist because that is the music this booth was built around: dense low end, brutal cymbals, vocals that have to sit on top of a wall. Other genre lanes are there when the reference you have is a pop or metalcore record instead. If you do not bring a reference, the preset still has an opinion. Bring one if you know the record you want to stand next to.
What it will not do: un-clip a brickwalled mix, invent a missing bass guitar, or make a phone voice memo sound like a $200-an-hour chain. If the snare is late, it stays late. If the vocal is a wash of reverb, brightness will make the wash hissier. Mastering is a polish pass. Mix first. Leave headroom. Export 24-bit WAV. MP3 sources are accepted because people still bounce wrong; they are the worst input.
This is a server job. Matchering is too heavy for a polite wasm tab. You upload, the private box processes, you download, the file is purged after six hours. Do not treat the server as object storage. If the track is unreleased, that retention window is the trade: you get a real masterer, you accept a short-lived copy on a machine you do not hold. For a bedroom demo you are fine with, that is a fair trade. For a major-label leak, use an offline chain.
After you download, listen on a system you trust, not only laptop speakers. Check the start for fade weirdness and the loudest chorus for pumping. If punch is too much, back it off and rerun. Width can make a mono-compatible club system sad; check a mono fold. Then dither to 16-bit only when you need a CD or a store that still asks.
A five-minute deathcore mix, 24-bit/48 kHz WAV, peaks at -6.2 dBFS, 48 MB. Reference is a commercial track from the same subgenre. Preset: deathcore, loudness slightly behind the reference, brightness a notch down so cymbals do not become razors, punch moderate, width conservative. The returned master is competitive in a playlist without turning the kick into a click. You still hear a busy arrangement problem in the second verse — mastering did not fix that, correctly. File is gone from the box within six hours.
MasterShift is a server-side Matchering job. You upload the mix and any reference; processing happens on a private converter. Files are deleted after six hours. Do not upload material you cannot let sit on a disk you do not hold for that window. There is no public library of masters.

Matchering and limiters need room to work. A mix already glued to 0 dBFS will distort or pump. 24-bit keeps the noise floor low while you leave that headroom. 16-bit slammed WAV is a hostile input.
No, but a reference in the right neighborhood beats hoping the preset guessed your loudness target. Pick a commercial track you want to sit next to, not a random EDM smash if you wrote deathcore.
For demos, Bandcamp, and 'I need it tonight,' it is a serious Matchering booth. For a vinyl cut or a label that hired a specific engineer, send them the mix, not this output as a fait accompli.
It is processed and then deleted after six hours. Download promptly. Do not rely on the server as backup. If that window is unacceptable, master offline. Treat the server as a booth you walk out of with a file, not as object storage for stems.
