Sampling Rates
When selecting linear (PCM) uncompressed audio or AAC, MPEG and aptX® Enhanced algorithms,
it is possible to select different either 32kHz, 44.1kHz and 48kHz sample rates as required. Tieline
Music runs at 32kHz sampling and MusicPLUS runs at 48kHz sampling. G.711 and G.722 will
always run at a 32kHz sampling rate (downsampled to 8kHz and 16kHz respectively).
