Real-Time Millisecond Audio Gap Detection in Live Wireless Streams

The patent segments the audio stream into discrete audio frames with associated timestamps, allowing precise measurement of gaps between frames. This segmentation enables detection of millisecond-level gaps that would be imperceptible in continuous audio analysis, directly resolving the contradiction between measurement precision and system complexity.

The system performs preliminary actions by pre-establishing timestamp synchronization and buffer management mechanisms before gap detection is needed. The audio player continuously tracks expected arrival times of audio frames, so when gaps occur, the detection is immediate and precise without requiring complex real-time analysis, thus improving measurement precision while controlling complexity.

The audio player performs self-service by autonomously monitoring its own buffer status and gap conditions without requiring external intervention. The system uses its internal timestamp tracking and buffer management to detect gaps and report quality metrics, achieving reliable real-time detection while minimizing processing overhead since the player is already performing these functions for normal audio playback.

The system implements feedback mechanisms where the audio player continuously monitors gap durations and reports quality metrics to the wireless network controller. This feedback loop enables real-time reliability improvement by allowing dynamic adjustment of transmission parameters based on actual gap detection, while the feedback is efficiently processed through established communication protocols that do not significantly increase processing time.

The patent changes the detection parameter from continuous audio analysis to discrete frame-based timestamp comparison. By using the standardized frame duration and timestamp synchronization parameters, the system achieves high sensitivity for detecting genuine gaps while the discrete nature of the parameter changes provides natural filtering against false detections, as random variations in audio data do not produce consistent timestamp discrepancies.

The system applies local quality analysis by examining the specific characteristics of each audio frame and its timestamp relationships individually. Rather than applying uniform detection thresholds across the entire audio stream, the system analyzes local gap conditions between consecutive frames, allowing precise detection of actual gaps while reducing false positives by considering the contextual quality of each local region in the audio stream.
