Subject: [PATCH] fix(ios): don't mix recording with other apps' audio
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The AVAudioSession options used when configuring a recording session
currently include .mixWithOthers, which keeps other audio apps
(Spotify, Apple Music, Podcasts, …) playing through the speaker
during the recording. The microphone picks that audio up and bleeds
it into the recorded file — turning every voice recording into a
mix of the user's voice and whatever music was playing.

Drop .mixWithOthers from the recorder session so starting a
recording interrupts other audio. Recording should always own the
audio route exclusively.

The player session (AudioPlayer.swift) is unrelated and not touched
here.
