I got this off the knowledge base at Creative for Audigy 4 Pro:
Playback of 64 audio channels, each at an arbitrary sample rate
24-bit Analog-to-Digital conversion of analog inputs at 96 kHz sample rate
24-bit Digital-to-Analog conversion of digital sources at 96 kHz to analog 7.1 speaker output
24-bit Digital-to-Analog conversion of stereo digital sources at 192 kHz to stereo output
16-bit to 24-bit recording sampling rates: 8, 11.025, 16, 22.05, 24, 32, 44.1, 48 and 96 kHz.
Supports Sony/Philips Digital Interface (SPDIF) format of up to 24-bit/96 kHz quality. Selectable sampling rate of 44.1, 48 or 96 kHz
Low latency multitrack recording with ASIO 2.0 support at 16-bit, 48 kHz and 24-bit, 96 kHz resolution.
It looks like they're saying that you can record in 24 bit but you are limited to 96 kHz. They have a history of deception so it's hard to interpret. What does this mean to you all? Can you record 24bit / 44.1?
