Padding 16 to 32 bits, if the source is 16 bits does not change dynamic. Now, there is a real benefit to use 32 bits integers as the internal representation when you chain calculations as you need a precision that using 16 bits interim results loses. If you take flac as an example, it always returns 32 bits samples. If youre want to store decoded flac in 16 bits arrays, you need a truncation loop. In addition, using 24 bits is a real problem for cpu. Integers are 8, 16, 32 or 64 bits but there is no such a thing as 24 bits representation and trying to fake one can complicate implementation a real lot. Hence we use 32 bits and truncate them to 24 bits at the very last stage. LMS 8.2 on Odroid-C4 - *SqueezeAMP!*, 5xRadio, 5xBoom, 2xDuet, 1xTouch, 1xSB3.
