[Feature Request] voice-changing-during-standby

[L483]

Problem/Motivation

The voice changing is not active while the smartphone is in standby. Keeping the smartphone active all the time unnecessarily drains a lot of battery. Probably, it is also expected from users that the app's main functionality also works while the smartphone is in standby.

Solution Proposal

The voice changing is also active while the smartphone is in standby.

Impact

May result in merge conflicts with #16, so this feature should be branched of the branch associated with #16.

Acceptance Criteria

• voice changing is applied even during standby
• documented the functionality

Further Information

Flutter Foreground Tasks seem like the correct approach. While different examples, even with audio streams, where working, it did not function in our project yet. We integrated [Flutter Sound] as a proof of concept at the beginning of the project. Flutter Foreground Tasks seem not to work with Flutter Sound, after much experimentation, the root cause of this issue likely lies within Flutter Sound.

This issue is paused, until the audio processing backend gets successfully connected to the app frontend (see #24 ). Then, Flutter Foreground Task should be tried again as a solution.
