Upload your track. AI masters it for Spotify, Apple Music, and more — then explains every decision in plain English. No credit card. No watermarks. No catches.
3 free masters/month · credits renew automatically · no subscription required
Free credits include the full AI mastering pipeline — no stripped-down version.
Your free credits renew automatically every month. Unused free credits reset; purchased credits carry over.
11 genre profiles — house, hip-hop, lo-fi, pop, rock, R&B, trap, dnb, ambient, jazz, deep house. Each with its own LUFS target, compression, and EQ.
After every master you get a coaching report explaining each EQ cut, compression setting, and loudness decision. Something LANDR never provides.
Free and paid masters are identical. Download the full-quality file and release it — no "preview only" restrictions.
Synchronized waveform players let you hear exactly what changed at the same position in both versions.
WAV/FLAC uploads return 24-bit WAV 44.1 kHz. MP3 uploads return MP3 320 kbps. All formats accepted by DistroKid, TuneCore, and CD Baby.
Spend credits on editable, AI-transcribed captions instead of mastering — 0.25 credits per transcript, SRT/TXT export, English vocals only.

Three steps. Under a minute.

Yes. Every account gets 3 free mastering credits every calendar month with no credit card required. There are no watermarks, no download restrictions, and no hidden catches on the free tier.
On the free tier you get 3 masters per month. Purchased credit packs (from $7 for 5 credits) carry over month-to-month and never expire. Every master — free or paid — includes the full AI mastering pipeline, a plain-English feedback report, and the before/after comparison player.
No. Free and paid masters are identical in quality and have no watermarks.
LANDR's free tier produces a watermarked low-quality preview — you must subscribe to download the full master. DJLynux gives you 3 full-quality, watermark-free downloads every month at no cost, plus a plain-English coaching report that LANDR does not provide.
DJLynux accepts MP3, WAV, and FLAC files up to 150 MB. WAV and FLAC sources are returned as 24-bit WAV 44.1 kHz. MP3 sources are returned as MP3 320 kbps. No upsampling of lossy sources.
All 11 genres — house, hip-hop, deep house, lo-fi, pop, rock, R&B, trap, drum & bass, ambient, and jazz — are included on every tier including free. Each genre has its own LUFS loudness target, compression style, and EQ profile.
No. DJLynux is entirely web-based. Upload your track in any modern browser — no plugins, no DAW, no software install needed.
Yes. Captions cost 0.25 credits versus 1 credit for a full master, so your 3 free monthly credits stretch to up to 12 caption generations, or any mix of mastering and captions.
Currently English vocals only. The transcription model is tuned for English; support for additional languages is on the roadmap.
3 free credits every month. No credit card. No watermarks. Just upload your track and get a release-ready master with a plain-English coaching report.
