Abstract
Methods and systems for correcting distortions of audio transmissions are provided. In one embodiment, a method is provided that includes receiving an audio transmission that includes symbols. A first portion of the audio transmission including a first subset of the symbols may be identified and compared to an expected sequence having expected symbols. One or more differences may be determined between the first subset of the symbols and the expected symbols and a movement speed between a transmitter and a receiver of the audio transmission may be determined based on the differences. A second portion of the audio transmission may be identified including a second subset of the symbols in the second subset of the symbols may be corrected based on the movement speed between the transmitter and the receiver.
