Direct answer
ToneEQ can use MusicKit to browse and control authorized Apple Music content, but protected Apple Music audio remains inside Apple’s platform playback path. ToneEQ does not receive the decoded stream, so its software EQ cannot be applied to that protected audio.
How it works
MusicKit provides authorized catalog, library and playback capabilities. It does not hand a third-party app an unrestricted decoded copy of protected tracks for custom DSP.
ToneEQ keeps platform playback separate from its local audio engine and shows the active processing path instead of presenting a decorative EQ as if it were audible.
Apple Music browsing and platform playback are not placed behind a ToneEQ Pro paywall.
When to use it
- Use Apple Music inside ToneEQ when you want one library view and clear playback-state information.
- Use compatible local files when you need ToneEQ’s graphic EQ, parametric filters, AutoEQ layers or Listening Match result.
- Check the processing indicator after changing sources.
Limits to know
- Availability and catalog behavior depend on Apple, the user’s subscription, authorization and region.
- ToneEQ never downloads, decrypts or records protected Apple Music streams.
- Apple may offer its own sound settings outside ToneEQ; those remain platform-managed.
Frequently asked questions
Why can I move EQ controls during Apple Music playback?+
ToneEQ can preserve your settings, but it marks software EQ unavailable when the current protected stream is not processed by its engine.
Is Apple Music a Pro feature?+
No. ToneEQ Pro adds profile organization and personalization; Apple Music authorization and platform playback are not the Pro paywall.
