Call mode and note mode

Use note mode for speakerphone or room audio, and call mode for private phone calls.

Steps

1. Note mode records the surrounding environment and is best for meetings or speakerphone calls.
2. Call mode is designed for phone calls where the iPhone uses the earpiece instead of speakerphone.
3. Choose the mode before recording so the app can label the source correctly.
4. After transfer, both modes appear as Audream device recordings with mode metadata.
