According to disclosed embodiments, methods and systems of data transmission are provided. An aspect of the present disclosure is a method comprising receiving an audio stream, parsing the audio stream into packets, encoding each packet using Alphabet Linear Network Coding (ALNC), and transmitting the encoded packets.

Systems and methods for audio transport

Systems and methods of the present disclosure enable heterogenous device interoperability for signaling across a network by configuring each transmitter and receiver to implement an interoperability tranche protocol. According to the interoperability tranche protocol, a transmitter generates multiple audio streams based on an original audio signal and a tranche function, where the tranche function is configured to produce the audio streams from the original audio signal at different quality levels. The transmitter transmits the audio streams across a network to each receiver on the network. According to the interoperability tranche protocol, each receiver receives the audio streams and generates an output audio signal based on an interpolator function and the audio streams. The interpolator function combines the audio streams and interpolates missing data from at least one of the audio streams using data from at least one other of the audio stream.

The present disclosure provides for novel systems and methods of audio transmission that alleviate shortcomings in the art, and provide novel mechanisms for robust and scalable audio transmission. In some embodiments, a method of audio transmission may transmit source audio data through a forward link while receiving microphone audio data from a receiver via a reverse link.

The present disclosure provides for novel systems and methods of audio transmission that alleviate shortcomings in the art and provide novel mechanisms for robust and scalable audio transmission. In some embodiments, a method is provided for receiving an input time datum, determining a time period from the input time datum to a second time, the second time occurring after the input time datum, determining a value for at least one parameter of an adjustable filter based on the time period, configuring the adjustable filter based on the value of the at least one parameter, determining an output time datum by applying the configured adjustable filter to the input time datum, and outputting the output time datum.

Systems and methods for audio timing and synchronization

The present disclosure provides for systems and methods for resolving discontinuities in audio data. The systems and methods include receiving, by a receiving device, a sequence of audio data blocks that has at least one missing. A repeat buffer of the receiving device buffers each audio data block in order according to the sequence. The receiving device resolves the discontinuity by accessing in the repeat buffer a previous audio data block preceding the at least one discontinuity, flipping the time indices of the previous audio data block, determining a slope of the audio data and flipping the slope to generate a vertically and horizontally flipped audio data block. The vertically and horizontally flipped audio data block is filtered using a glitch filter and crossfaded into the previous audio data block to produce output audio data that conceals the at least one missing block.

Systems and methods to conceal un-recoverable audio blocks

The present disclosure provides for novel systems and methods of audio transmission that alleviate shortcomings in the art, and provide novel mechanisms for robust and scalable audio transmission. In some embodiments, a method of audio transmission may transmit auxiliary data via at least one of a forward link and a reverse link.

Systems and methods for transport of auxiliary data

A method of associating audio devices into a network association, including alerting a network of the presence of a first audio device by engaging a first button associated with the first audio device; assigning a first role to the first audio device; alerting the network of the presence of each subsequent audio device by engaging a subsequent button associated with each subsequent audio device; assigning a subsequent role to each subsequent audio device; and alerting the network that all subsequent audio devices have been identified by engaging the first button associated with the first audio device.

A multichannel audio system with a plurality of multichannel speakers having microphones, where the system receives audio signals from multichannel speakers, an adaptive filter enhances the voice signal portion of the audio signal by canceling interference in the audio signals by eliminating the portion of the audio signal matching reference signals, and processing the voice signal into voice commands.

Voice detection with multi-channel interference cancellation

A system and method for adapting an audios stream for reducing latency. The method may include the steps of, and the system may function to, receive an audio stream having a packet buffer and an audio buffer, measure the audio buffer depth of the audio buffer, measure the presentation time margin of at the input to the packet buffer, and determine an adaptation level for latency based on the measured values.
