Re: Delta 1010, drivers, and GSIF2: The Pulse-Pounding Question
GSIF-2 has three parts:
1) MIDI input - this is faster than in GSIF-1
2) Audio input - this is new for GSIF-2. Now we can take in external audio and run NFX effect of it - including GigaPulse
3) Audio output - unchanged from GSIF-1
It's strage that the new driver has added the 24-bit requirement on capture. It should not add any latency, since Giga works with 32-bits internally regardless of the setting. Also, PCs are 32-bits these days, so each data access can handle 24-bits with no extra load.
Yes, one can pack two 16-bit words into a single 32-bit data register, but that's often slower, since the CPU has to shift and mask the words to combine and separate them.
BTW, I'm running an Audiophile 192 with GSIF-2 drivers and the latency is excellent.
