  Audio packet loss concealment is the hiding of gaps in VoIP audio streams
caused by network packet loss. With the ICASSP 2024 Audio Deep Packet Loss
Concealment Grand Challenge, we build on the success of the previous Audio PLC
Challenge held at INTERSPEECH 2022. We evaluate models on an overall harder
dataset, and use the new ITU-T P.804 evaluation procedure to more closely
evaluate the performance of systems specifically on the PLC task. We evaluate a
total of 9 systems, 8 of which satisfy the strict real-time performance
requirements of the challenge, using both P.804 and Word Accuracy evaluations.
