formats · workflow · privacyOhms Restore reads and writes WAV, AIFF and FLAC. Choose one or more source files with the macOS file picker, then choose a folder for the restored copies. Metadata chunks the app does not understand are reported as not copied.
Yes. With an empty queue, choose Load demo recording. A short recording that ships inside the app is added to the queue, so you can analyze, repair and compare it before touching your own transfers.
No. Sources are opened read-only. Each restored copy is written as a new file in the folder you choose, then reopened and checked against the source's format, sample rate, channel count, length and bit depth before the job is marked verified.
After a file is analyzed, Review Suggestions proposes which stages to switch on, a confidence for each, and the measurements behind it. Nothing runs until you choose Apply suggested recipe and start the batch, and every stage stays editable. When the analysis is not conclusive, it says so instead of guessing.
The six-stage chain handles short clipped peaks, clicks and crackle, 50 or 60 Hz mains hum and its harmonics, steady broadband hiss, unwanted low or high bandwidth, and overall level. Each stage can be bypassed. Restoration cannot recreate information that was never captured; long clipped passages may be detected but left unrepaired.
Add files, analyze the queue, set one chain and start. You can pause after the current file, cancel a running job, remove queued items, and read a plain reason when a file fails, without losing exports that already finished. Ohms Restore adds the files you pick; it does not scan a whole folder on its own.
Once the restored copy has been exported and verified. Play it and press B to flip between original and restored without stopping. Both are matched to the same loudness on a BS.1770 meter, with a shared safety ceiling, so louder is not mistaken for better.
A versioned project package. Open one from Finder or with File > Open Ohms Project. Ohms Restore checks every declared audio file against its recorded checksum and size before anything is queued, refuses malformed or tampered packages, keeps a copy of the validated package in its own container, and adds the rendered audio to the repair queue.
No. Ohms Restore uses native local signal processing and contains no networking code. There is no cloud service, account, analytics, telemetry, model download or helper server. Its bundled interface is served from a private app origin with network connections blocked by policy. From version 1.4.2 the sandbox includes the outgoing network client entitlement only because macOS WebKit's helper processes need it to show that interface.
An optional, human-readable JSON record of a finished batch: the recipe, the measured analysis, detected defects, warnings and verified output details for each file. It is saved only when you choose Export ledger, to a location you pick.
Ohms Restore is a $17.99 one-time Mac App Store purchase. There is no subscription, in-app purchase, usage credit, account or online activation beyond the App Store receipt.
