andyr Posted October 8, 2019 Posted October 8, 2019 I'm curious to know what the O/P sample rate of a DAB+ tuner is - anyone know. The reason I ask is that I know when I feed a CDP into the digital input of my miniDSP 10x10HD unit ... the input stream is 44kHz - and the miniDSP upsamples this to 96kHz. But what's the input stream when the input to my miniDSP is the DAB+ tuner? Anybody know? Andy
Ittaku Posted October 8, 2019 Posted October 8, 2019 (edited) Did some googling for you. Looks like 48kHz (or lower multiples of 8 ) so you're in luck if upsampling to 96. Of course the broadcaster has already resampled to 48 themselves but you're avoiding yet another non-integer resample. Edited October 8, 2019 by Ittaku

aussievintage Posted October 8, 2019 Posted October 8, 2019 I followed this question because it was of interest. May I ask though, that table appears to be the sample rates used by the radio transmission, and received by the DAB+ radio, but the DAB+ chip could conceivably upsample all them before transmitting it out of a digital interface on the radio couldn't it?

Good question, av! Can the Xsperts respond? Andy
