Note:
(1) Please click "get HCA info" button first.
(2) Setting decoding mode to zero means 32-bit float mode, or 8/16/24/32-bit integer mode otherwise.
(3) Loop count is ignored if HCA header doesn't have loop section
(4) Loop count doesn't count the existing part which is originally supposed to be looped.

(5) When decoding the whole file, setting loop count to zero means: disabling loop.
