I'm noticing interruptions and/or weird audio artifacts on my recordings. Ideas?
To prevent GSM interference as well as interruptions from calls or texts while recording, we recommend using Airplane Mode on the Apple device. The "Do Not Disturb" setting also should prevent interruptions from alerts, calendar reminders, etc.
Checklist (adapted from Apple's Developer site):
Settings App: Airplane Mode, Do Not Disturb
Clock App: no clock alarms are enabled
Calendar App: no event alarms are enabled
Do not move the "Silent" switch while recording
Do not plug / unplug headphones or charging cable; do not dock or undock the device
