• BitPerfectMode
Bit-perfect mode allows user to use ASIO or similar function while doing audio
playback, avoiding any sample rate conversion being done by PC’s operating
system. This feature keeps audio contents of all resolutions being played as
its original sample rate without any potential quality loss during sample rate
conversion.
