Audio Notification Controller for Collision-Free Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern mobile computing devices face challenges in intelligibly handling simultaneous audio notifications from multiple applications, leading to 'audible stream collisions' that complicate the comprehension of important information, such as navigation instructions during phone conversations.
Innovation Solution
Implementing a sound controller module that prioritizes audio feeds by detecting signal gaps in higher-priority streams and modifying lower-priority notifications through delay or time compression to avoid collisions, ensuring that only one audio stream activates speakers at a time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple applications provide audible notifications simultaneously, then the device can deliver information from all applications, but the intelligibility of the notifications deteriorates due to audible stream collisions
Solution Approach 1:
The system performs preliminary prioritization of audio feeds before output, assigning priority levels to different applications. By pre-establishing the playback order and detecting signal gaps in advance, the system prevents collisions before they occur, ensuring that high-priority notifications are delivered intelligibly without interference from lower-priority streams.
Solution Approach 2:
The system dynamically adjusts the playback timing of audio feeds based on detected signal gaps in higher-priority streams. Lower-priority notifications are delayed or time-compressed in real-time according to the actual audio landscape, allowing the system to adaptively manage multiple notifications while maintaining intelligibility of critical information.
2Loss of information
If the system delays lower-priority audio feeds to avoid collisions, then the intelligibility of high-priority notifications is improved, but the duration of action of lower-priority notifications increases
Solution Approach 1:
The system changes temporal parameters of lower-priority audio feeds by applying time compression algorithms. This reduces the duration of delayed notifications, allowing them to be played back more quickly after the signal gap is detected, thereby minimizing the overall delay while still preventing collisions with high-priority streams.
3Duration of action of moving object
If the system applies time compression to lower-priority audio feeds, then the duration of notification delivery is reduced, but the complexity of the audio processing system increases
Solution Approach 1:
The system introduces a sound controller module as an intermediary between the audio feeds and the output device. This mediator handles the complex tasks of priority assignment, signal gap detection, delay adjustment, and time compression, isolating these complexities from the application layer and providing a unified interface for audio output management.

AI summary
Certain implementations of the disclosed technology may include systems and method for handling application notifications. According to an example implementation, a method is provided. The method can include receiving a plurality of audio feeds from a respective plurality of applications, and determining a priority status for one or more of the respective applications. Based on the determined priority status, the method may further include determining a first prioritized audio feed and a second prioritized audio feed from the plurality of applications. The method includes detecting, in a signal associated with the first prioritized audio feed, a signal gap having a gap start. The method includes modifying, based at least in part on the signal of the first prioritized audio feed, one or more parameters associated with at least the second prioritized audio feed, and outputting, to an output device, at least a portion of the first prioritized audio feed.
