Abstract
Audio communication methods, devices, and systems, are provided with error correction overwrite for audio artifact reduction. One illustrative low-latency audio streaming method includes: receiving packets of digital audio data; applying an error correction code decoder to obtain a data stream that includes error-corrected data samples; providing a correction-limited data stream by replacing any of the error-corrected data samples that are outliers; and converting the correction-limited data stream into an audio signal.
Claims20
A low-latency audio streaming method that comprises:
- receiving packets of digital audio data;
- applying an error correction code decoder to obtain a data stream that includes error-corrected data samples and error-free data samples;
- providing a correction-limited data stream by replacing any of the error-corrected data samples that are outliers while forwarding the error-free data samples and any of the error-corrected data samples that are not outliers;
- and
- converting the correction-limited data stream into an audio signal.
A low-latency audio streaming device that comprises:
- an error correction code decoder that produces a data stream having error-corrected data samples and error-free data samples;
- a correction limiter that provides a correction-limited data stream by replacing any of the error-corrected data samples that are outliers and by forwarding the error-free data samples and any of the error-corrected data samples that are not outliers;
- and
- a decompressor that converts the correction-limited data stream into an audio signal.
A wireless system that comprises:
- a first hearing aid for a first ear, the first hearing aid including:
- a microphone to capture and digitize an input audio signal;
- a transmit chain that compresses the digitized audio signal into packets of digital audio data with error correction code protection;
- and
- a first wireless transceiver that operates to transmit the packets of digital audio data;
- and
- a second hearing aid for a second ear, the second hearing aid including:
- a second wireless transceiver that operates to receive said packets of digital audio data;
- an error correction code decoder that produces a data stream having error-corrected data samples and error-free data samples;
- a correction limiter that provides a correction-limited data stream by replacing any of the error-corrected data samples that are outliers and by forwarding the error-free data samples and any of the error-corrected data samples that are not outliers;
- and
- a decompressor that converts the correction-limited data stream into an audio signal.
