SBC: Intuition of audio impact of subbands? 2019-12-28 17:46:42 It has been some 25 years since I worked with digital filters, transforms and the such, but still have some basic intuition of how they work.SBC has many parameters that impact its audio performance, but the parameter that I most lack intuition for the subband number. It is clear from equations describing SBC that the bitrate of SBC doubles if you reduce the number of subbands by half. It seems that halving the subbands means that each subband doubles its frequency range, and if you were somehow able to keep the same final bitrate, you would have 2x the bits to characterize the signal in that 2x larger frequency band. Given that SBC can move bits between the subbands, such a scheme would not intuitively significantly change audio performance. But like I said before, halving the subbands in SBC doubles the bitrate, which in my intuition should have a positive impact on audio performance.It feels like I missing something trivially simple. Can anyone point me in a useful direction?
