Reliability pass — nothing gets lost between render and download

  • If a download ever stalls, we now rebuild the file on our servers and send it automatically — a finished master can no longer be lost because your browser dropped it
  • Fixed occasional distortion on dynamic and ballad-style tracks; masters now sit right at the ceiling without that edge
  • WAV files now carry a fully standard header — some distributors were rejecting our float WAVs at upload
  • The in-app AI scanner no longer gets stuck on "analyzing", and it handles long or large files properly
  • Uploads now show the supported formats and size limit up front, and a file we can't read is caught immediately with a plain explanation instead of failing later
  • Premium downloads follow the format and bit depth you picked, and Stem Remaster recovers on its own on slower machines instead of giving up
  • Free and event credits now show their expiry date (valid 90 days from the day they land); purchased credits still never expire

Engine v6.0 — Stem Remaster

  • Stem Remaster is now a full feature — your song is separated into vocals, drums, bass and instruments, rebalanced, then mastered. Mastering alone can't move the balance between instruments; this can
  • You get one finished master, not a folder of stems — the download set is the same as a normal master (WAV, lossless FLAC, MP3 320)
  • Charged when the render starts, and refunded in full if it fails or you cancel — you're never charged for something you didn't receive
  • Included in every subscription: Light gets 2 on signup, Standard 2 per cycle, Pro unlimited
  • Honest trade-off: the top end opens up and the stereo image widens, but the low-mids sit back a little — on sparse, already balanced songs the normal master is still cleaner. Run both and keep the one you like
  • New three-tier pricing in Korea — a ₩5,900 Light plan below the existing ₩12,900 tier, plus the ability to move down a tier instead of cancelling
★ Major update · ENGINE V5.5
2026-08-09

Engine v5.5 — reverse-engineered from professional masters

  • The mastering engine was rebuilt by reverse-engineering professional masters — we measured commercial releases against the mixes they came from, and matched the engine to what human engineers actually do: press the moment-to-moment dynamics hard, but leave the song's arc alone
  • Every track is treated on its own terms now — a song with heavy low end gets it cleaned up, and a song with a wide dynamic arc is pushed less so its chorus doesn't flatten out
  • The live preview finally sounds like the download — presence, air and level all line up, so the tone and width you set by ear come out the way you heard them
  • Anti-AI sounds like the rest of the presets — it used to arrive darker and quieter than the others; it now carries the same tone and the same level
  • Detection scores are higher than they used to be, though — the AI detectors themselves have gotten stronger recently, and codec-based evasion no longer moves them the way it did. We chose sound quality for this release, and we're researching a different approach to protection separately. Treat Anti-AI as "lowers the odds", not as a guarantee
  • Premium comes out at the standard level — it used to land about 3 dB quieter than a Fast Commit of the same song
  • One sound, whichever way your file is processed — the in-browser render, the server fallback and the API now produce the same master

Anti-AI preset: highs restored

  • Anti-AI masters keep their top end — the airy 16 kHz-and-up range that used to get thrown away now survives, so cymbals, air and reverb tails stay open
  • More dynamics kept — the same loudness, but about 1 dB more crest, so transients breathe instead of flattening
  • Protection held up or improved — on our test set the detection score came out the same or lower than before (it varies by track and by detector, as always)
  • Nothing changes on older browsers — if your browser can't do the new processing, you get exactly the previous Anti-AI result, not a worse one
  • AI detector is more accurate — it now listens to a longer stretch of the track and is no longer fooled by tiny speed/pitch changes, so AI tracks that used to slip through are caught (12/12 on our test set, with no false alarms on human-made music)
  • AI tracks are recognised even when the file has no AI tag — re-encoded or re-exported AI songs get the AI-tuned processing instead of the general one
2026-07-11

Cleaner, more open Anti-AI masters

  • Clearer Anti-AI sound — the Anti-AI preset now opens up more, with a cleaner low end instead of the previous boxy feel
  • Per-song tonal cleanup — each track gets a gentle tonal-balance pass that tames muddy or boomy areas while keeping its character
  • Same protection — the detection-score reduction is still a side effect of the mastering (varies by track & detector); that part is unchanged
2026-06-21

Smarter genre recommendation

  • Smarter "Better sound" — the easy wizard now listens to your track and recommends the preset that best matches its genre, far more accurately than before
  • Handles in-between tracks — melodic dance, K-pop and other hard-to-place styles now get the right vibe instead of a mismatched preset
  • Still your call — the suggestion is just a starting point; switch to any other style in one tap
2026-06-17

Consistent loudness · clearer Premium files

  • Consistent loudness — every preset now lands at the same level, so switching presets no longer surprises you with a louder or quieter master
  • Preview matches the download — the level you hear in the live preview now lines up with the file you get
  • Cleaner on loud inputs — hot or squashed tracks no longer pump or get over-squeezed
  • Clearer Premium downloads — Premium files now carry "Premium" in the filename, with the 96 kHz master included
2026-06-13

Smoother finish · more guides

  • Even smoother finish — we tightened the final result step so your master comes through cleanly on a wider range of setups
  • More mastering guides — fresh how-tos for AI music creators are now live on the blog
2026-06-13

Smooth on more machines

  • Finishes every time — if mastering used to stall at the final step on some computer setups, our server now takes over automatically and completes it reliably
  • Clear status — when stable mode kicks in, you always see what's happening
2026-06-10

Steadier sessions · stronger Match-EQ consistency

  • Rock-steady back-to-back mastering — fixed the cases where the page could jump back or drop out while processing many tracks in a row
  • Stronger Match-EQ consistency — the same track with the same settings always delivers the same master, every time
  • Instant commit — switch presets and master right away, with no waiting
2026-06-04

See it in action — demo videos on the home page

  • New demo section on the home page — watch a full AI track go from raw to mastered, plus the one-click Wizard, before/after A/B, AI-detection score drop, and automatic genre matching
  • Tap any clip (or its speaker icon) to hear the sound — only one plays at a time, so nothing overlaps
  • Clips follow your language — Korean or English narration switches with the site toggle
  • Lightweight by design — videos only play while on screen, so they don't drain mobile data or battery
2026-06-03

Sample try-out, clearer results & refund terms

  • Try before you commit — master a bundled sample track for free, hear before/after, and see the AI-detection score (no charge, no download needed)
  • After the sample, one tap takes you straight to mastering your own track
  • Anti-AI goal now leads with the score change (before → after, e.g. 99% → 45%) right at the top of your result
  • Clearer refund terms across the site — full refund within 7 days as long as you haven't downloaded a master yet (downloading uses the credit)
2026-06-01

Easy Wizard mode — guided one-click mastering

  • New Wizard mode (now the default) — master in four simple steps: upload → pick a goal → master → see your result
  • Pick your goal in plain language: 'Better sound' or 'Lower AI-detection score' — we set everything up for you, no knobs to learn
  • The result shows the AI-detection score before and after, side by side, so you can see the change at a glance
  • Full Pro mode (all knobs + presets) is always one tap away via the top-right toggle — and your choice is remembered
  • Cleaner downloads — files from Wizard mode are named simply, without internal preset codes

  • Free re-mastering — the same file with the same preset never charges twice (privacy-safe; we don't store your audio on the server)

  • Smarter checkout — sign in mid-flow and you're sent right back to the payment page (no plan re-selection)
