DTS hard decoding is to decode audio files through the dedicated audio processing chip on the sound card, which does not occupy system CPU resources.
DTS soft decoding is to output audio information by CODEC chip after decoding by CPU.
Hard decoding is faster than soft decoding, high quality, does not occupy system resources and other advantages, but requires another decoding chip, the cost is higher than soft decoding
