5. Spare Packets

Enable this feature to boost the tolerance to packet loss. You can either enable spare packets (the default state) or disable them using VCT_EnableSparePacket.

Spare packets are appended to the end of the normally used audio packets (called the main packets). Spare packets contain a compressed copy of the audio from the preceding main packet. Any packets lost on the receiver side can be filled in using the audio data in the spare packets included in the next packet, restoring otherwise lost audio frames. This helps maintain audio quality in the wireless environment and other environments prone to packet loss.

To minimize the increase in bandwidth usage, 2bit ADPCM is the only codec supported for spare packets.
