Abstract: Methods, devices, non-transitory computer-readable medium, and systems are described for compressing audio data. The techniques involve obtaining a sequence of digitized samples of an audio signal, performing a transform using the sequence of digitized samples, to generate a plurality of spectral lines, obtaining a group of spectral lines from the plurality of spectral lines, and quantizing the group of spectral lines to generate a group of quantized values. Quantizing the group of spectral lines to generate the group of quantized values may comprise performing a specialized rounding operation on a spectral line selected from the group of spectral lines and using the specialized rounding operation to force a group parity value, computed for the group of quantized values, to a predetermined parity value. One or more data frames based on the group of quantized values may be outputted.

Abstract: A first device may establish, with a second device, a short-range wireless communications link. The first device may determine a time interval between each of a set of packets to be transmitted over a short-range wireless communications link with a second device. The first device may encode data with a bitrate that is based on the time interval. The first device may packetize the encoded data in the set of packets. The first device may transmit the set of packets to the second device or the short-range wireless communications link, and each of the set of packets may be separated by the time interval when transmitted.
