What it does
> Most AI mastering tools take one mixed file and apply a one-size-fits-all chain — they can't tell vocals from drums, so they over-compress the vocal trying to control the kick. OneMaster is stem-aware: upload beat and vocal as separate channels, and the AI enhances each independently (de-essing vocals, prepping beats), then sums and runs a 3-pass loudness chain calibrated to Spotify/Apple delivery specs (-9 LUFS, -1 dBTP, 24-bit). 10s delivery, 5 free previews, $15/song.
Commercial-grade mastering via a 3-stage AI pipeline. Vocal + beat are enhanced separately, then mastered together. A modern AI mastering studio in your browser.
It improves each channel on its own, then combines them into a single commercial-grade master. 🎧 Hear the whole result free, download it if you like it · ✨ every master comes with 3 free revisions on the same files. Real tracks, mastered in one click. Toggle before/after while it plays — headphones recommended. How loudness, stems and AI mastering actually work — including honest comparisons with the other tools, and where they beat us. LUFS, true peak, headroom, crest factor, dither, codec — the mastering words you keep meeting, each in plain language with what it changes in your work. Your master is done. Here is what to check before it goes to a distributor: true peak, file format,…from onemaster.ai

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
