Yes, sample_pf_pc in this case is 2048, and the decoder output is 4096
No, this is not that.
In my example, samples per channel actually is the same as samples_pf_pc,
this is just the second value in cook's extradata.
so samples_pf_pc = 1024.
output size in bytes from the decoder (datasize) for one frame then should
be 8K (assuming 4 bytes/sample), which is your equation :
