## About ARP (present ship state — 2026-08-14)

ARP (Audio Revival Processor) restores local audio on-device using RNNoise (a recurrent neural network) and DSP — no Core ML. Audio files are not uploaded to ARP servers.

**Shipping (App Store app id 6758187060):**
- iPhone, iPad, and Apple Watch (Watch is a playback remote; it does not process audio)
- Premium product ID: `ARP.ARP.premium` — one-time purchase (~$6.99 USD list), not a subscription
- 10 free enhancement credits; M4A export free; 24-bit WAV/AIFF export with Premium
- Store: https://apps.apple.com/app/arp-voice-denoise-player/id6758187060

**Not shipping yet:**
- Mac App Store listing / Universal Purchase — a native Mac app exists; buying Premium on iOS does not unlock Mac

### Core value propositions (as built)
- On-device AI noise reduction (RNNoise) + DSP enhancement pipeline
- One track at a time (batch queue is roadmap — not shipped)
- Music: classifier skips RNNoise on clean music; playback EQ + loudness match still run (does not "restore" low-bitrate rips)
- Voice/speech material: RNNoise + expander + limiter + loudness match
- 10-band parametric EQ (playback) + optional playback bass shelves (Settings)
- Widgets; Live Activity during **enhancement** (not a duplicate Now Playing during normal playback)
- Apple Watch companion as remote
- No cloud, no account, no telemetry — nothing leaves the device (no iCloud library sync)

### Do NOT claim as shipped
- Mac App Store / Universal Purchase / one purchase unlocking Mac
- Batch processing
- CarPlay
- Live Metal spectrogram / multi-theme visualiser
- 96 kHz export (exports use the source file's native sample rate)
- Crossfeed / DSD / hi-res marketing claims

### FAQ
- Does audio leave my device? No.
- Batch processing? Not today.
- Subscription? No — one-time Premium.
- Voice Memos? Share into Files first; not a direct import source.
- Mac? Native Mac app is coming; not on the Mac App Store yet. iOS Premium does not unlock Mac today.
