What stays on your device
Microphone audio, the Perch model, and every identification run locally. Imported files,
batch folders, spectrograms, and exports are processed on the device too. On the Mac,
recordings are only kept if you turn Keep recordings on.
The one exception is optional: if you leave photos and song examples enabled, Wild Noise
asks Wikipedia and Wikimedia Commons for a species by its scientific name. That sends the
name, never your audio. You can turn it off in Settings.
Requirements
- macOS 13.4 or later, on Apple silicon or Intel
- iOS or iPadOS 16 or later, on iPhone and iPad
- The model is bundled, so there is no first-launch download and it works offline immediately
- A microphone, ideally not the one next to your Mac's fan
A word on accuracy
The score compares the candidates it is showing you; it is not proof of an identification.
Wild Noise filters rumble and steady fan-like noise before it listens, but a laptop fan can
still read as wildlife to a sensitive model. Treat a match as a good lead, not a record.
Identification uses Google's Perch 2.0 bioacoustic model. Full policy:
