void	receive_udp (AsyncUDPPacket &packet)
	VBAN adjusts the number of samples per packet according to sample rate. Assuming 16-bit PCM mono, sample rates 11025, 22050, 44100, and 88200 yield packets containing 64, 128, 256, and 256 samples per packet, respectively. The even-thousands sample rates below 48000 yield non-power-of-2 lengths. For example, sample rate 24000 yields 139 samples per packet. This VBAN->DMA->DAC method seems to require the dma buffer length be set equal to the number of samples in each VBAN packet. ESP32 I2S/DMA does not seem to handle non-power-of-2 buffer lengths well. Sample rate 24000 doesn't work reliably at all. Sample rate 32000 is stable but stutters. Recommend selecting from sample rates 11025, 22050, 44100, and above And set samplesPerPacket to 64 for 11025, 128 for 22050, or 256 for all else.
