Playback Audio Profile Matching for Multi-Room Setting Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio playback systems lack the ability to dynamically adjust audio settings based on the type of music being played, leading to suboptimal listening experiences when transitioning between different genres or tracks, and fail to synchronize settings across multiple playback devices in a network.
Innovation Solution
The system determines an audio profile for a representative set of songs and compares it to the currently playing song, providing warnings or adjusting settings accordingly, while also replicating these settings across similar devices in a playback network to ensure a consistent listening experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio settings are manually adjusted by users, then user preference is maintained, but the system cannot dynamically adapt to different music genres or tracks
Solution Approach 1:
The system performs preliminary actions by determining audio profiles for multiple songs in advance and storing them. When a song is played, the system compares the current song's profile against the stored profiles to automatically adjust settings, eliminating the need for real-time complex analysis during playback.
Solution Approach 2:
The system creates copies of audio profiles from representative sets of songs and stores them for quick comparison. Instead of analyzing each song in real-time, the system uses pre-generated profile copies that can be rapidly matched against playing songs to determine appropriate audio settings.
2Adaptability or versatility
If audio settings are adjusted for one playback device, then that device optimizes playback, but other devices in the network do not benefit from the same optimization
Solution Approach 1:
The system merges the audio settings and profile data across multiple playback devices in a network. When a profile is determined or adjusted on one device, the system combines this information and replicates it to other devices, ensuring consistent optimized playback across the entire network without requiring separate configuration for each device.
3Loss of information
If the system provides warnings before adjusting audio settings, then user awareness is improved, but the adjustment process becomes slower
Solution Approach 1:
The system implements feedback by providing warnings to users before audio settings are automatically adjusted. The warning mechanism informs users of the impending change based on the profile comparison, allowing users to confirm or cancel the adjustment, thus maintaining user awareness while enabling quick automated adjustments when confirmed.

AI summary
Embodiments described herein provide for smart configuration of audio settings for a playback device. According to an embodiment, while a playback device is a part of a first zone group that includes the playback device and at least one first playback device, the playback device applies a first audio setting. The embodiment also includes the playback device joining a second zone group that includes the playback device and at least one second playback device. The embodiment further includes the playback device applying a second audio setting based on an audio content profile corresponding to the second zone group.
