Frequently asked
How do credits work?
One credit = one Enhanced or Restoration refinement. Flow Matching costs 3 credits per run on Normal quality or 4 on High — Normal runs ~40% faster and is the default. AI Artifacts (cleaner-only) costs 2. Finalize (mastering) is a free add-on to any full-track refinement, or 1 credit standalone — Pro and Studio only. There are no per-preset caps — if you have credits, you can spend them on any preset. Credits come from your subscription (resets monthly) or from purchased Credit Packs (never expire).
Can anyone run Flow Matching?
Yes. Flow Matching is available to every tier as long as you have enough credits (3 on Normal, 4 on High). On Free you get 2 monthly credits, so you'd need to buy a Credit Pack first; on Hobby ($9/mo) up to 5 Normal runs from your monthly allotment; on Pro ($29/mo) up to 10; on Studio ($49/mo) up to 20. Pick Normal for the cheaper, faster option — High does more passes through the model for finer detail.
Can I cancel any time?
Yes. Cancellation takes effect at the end of your billing period — you keep your tier and any remaining subscription credits until then. Pack credits are yours forever.
Do unused subscription credits roll over?
No. Subscription credits reset on renewal (use it or lose it). Pack credits never expire — they're a separate bucket that drains last.
What happens to my files?
Uploaded and refined files are deleted 7 days after refinement completes. We don't train on user audio. We don't share files with third parties. Your tracks are yours.
Do you support 48 kHz output?
Yes — on Pro and Studio. Free and Hobby export at 44.1 kHz. Pro and Studio pick 44.1 or 48 kHz per refinement.
Can I export 32-bit float WAV?
Yes — on Pro and Studio, when you pick the Flow Matching preset. 32-bit float keeps full headroom for further mixing in a DAW with no clipping risk. The toggle only appears next to Flow Matching because the Enhanced preset emits at its model's native bit depth and doesn't accept the override.
What is the AI Artifacts preset?
It's our AI-artifact cleaner running on its own — no model after. The cleaner uses source separation plus per-stem DSP to strip residue specific to AI-generated audio (subtle haze, unnatural peaks, generation noise) so you get a noticeably cleaner version of the same track. Available on Pro and Studio, 2 credits per run, ~2–6 minutes depending on track length. Important: this is for cleaning audio quality, NOT for evading AI detectors. We don't try to defeat C2PA, watermarking, or detection systems — the goal is to give you a better-sounding file, not to disguise its origin.
What is Finalize (mastering)?
Finalize is our automated mastering stage — the last step of the chain. As a toggle on any full-track refinement (Pro and Studio, no extra credits) it masters the refined file: corrective EQ, glue compression, valve-triode and transformer harmonic saturation, stereo polish with a mono-safe low end, and a true-peak limiter, at a −9 LUFS release target with a −1 dBTP ceiling. As a standalone preset (1 credit) it does the same to a track that's already mixed. On refinement jobs — Enhanced, Restoration, Flow Matching, or AI Artifacts — the mastered version is the default download and the pre-master stays available as a second file; standalone delivers the mastered file, and your upload is the pre-master. It won't replace a mastering engineer on a commercial release, but it closes most of the gap between an AI export and a released track.
Is stem separation included?
Stem separation is a Pro feature (Pro and Studio). 3 credits per split, regardless of which engine you pick (Demucs, Melband, or Voice Cleanup). Free users get one lifetime trial split so you can try it before deciding to upgrade — Hobby is refinement-only.
What if a refinement fails?
Credits are automatically refunded to the bucket they came from. If the failure was on our side, you'll see "credit refunded" in your activity log within seconds.
Can I upload music I didn't make?
No. By uploading, you confirm you have the rights to the audio. We don't enable processing of copyrighted material you don't own.
Is there a refund policy?
Subscription cancellation stops future charges. We don't proactively refund partial billing periods, but reach out at support@therefiner.app if something went wrong and we'll make it right.
Do you offer team plans?
Not yet — Studio ($49/mo, 60 credits) is our heavy-individual-user plan, not a multi-user team plan. Email us if you're a label or studio with multiple users sharing one account — we want to understand your workflow before designing for it.
