Q: How do I get my recordings out of the app?
Open a session and tap EXPORT. Pick WAV 24/48 or AAC 256, choose whether to apply the master chain, and optionally export one stem per channel. Files land in the iOS share sheet.
Q: The app closed mid-take. Is my recording gone?
No — sessions auto-save as you work. Look for a project named “Recovered” in the Library tab; your takes are in there.
Q: What sample rate does it record at?
48 kHz at 24-bit, always. No hidden downsampling — what you export is what the mic captured.
Q: Does mastering change my original takes?
Never. Instant Master sits on the master bus and processes playback and export only. Your raw takes stay untouched, and you can A/B or remove the chain any time.
