Abstract
A system configured to reconstruct audio signals. The system may identify missing audio samples due to packet loss or detect distortion caused by audio clipping and may reconstruct the audio data. The system may employ a forward-looking neural network that recursively predicts audio samples based on previous audio samples and/or a backward-looking neural network that recursively predicts audio samples based on subsequent audio samples. The system may generate audio data using only the forward-looking neural network for low latency applications or may generate audio data using both neural networks for mid to high latency applications. To reduce distortion in output audio data, the system may generate the audio data by cross-fading between outputs of the neural networks and/or may cross-fade between the generated audio data and the input audio data.
