Soneam is a review, approval and delivery platform for people who send finished audio to clients: mixing and mastering engineers, plus freelance producers. Clients listen, comment on the waveform, approve, and download the master without creating an account.
The difference is mastering-grade rigor. Playback is lossless FLAC generated from your original file, and delivery is checksum-verified with SHA-256, so the master a client downloads is provably identical to the one you uploaded. Integrated LUFS and true peak are measured and shown right in the approval flow, alongside a per-platform preview of how the track will sound after Spotify, Apple Music, YouTube, TIDAL and others normalize it. Fair Loudness lets you and your client A/B two versions at matched loudness, so the louder one does not win by accident.
Comments are pinned to a point or a region on the waveform and carry forward across versions, so a note left on version 1 follows the fix into version 2. Approvals are recorded (who approved, when, and which version), giving you a sign-off you can point back to later. Delivery pages are password protected, and you can require payment before download.
Reviewers never log in. Everything a client touches, including review, upload requests, and delivery, works from a link.
Pricing runs from a free tier through paid plans that differ only by storage, not by features.
