Default Re: So, latency on HD Native vs HDX?

To set the record straight, no, it's definitely not.

96kHz with HDN at 64 buffer is slightly lower than 44.1kHz on a TDM system, but it's over three times the latency of 96kHz (0.48ms) with a TDM system (if you're using HD I/O with both systems for a fair comparison). HDX at 96kHz is 0.50ms. TDM and HDX are that low REGARDLESS OF BUFFER.

HDN is 1.67ms, but only at 96kHz and with a buffer of 64. At a buffer of 128 it's unusable for tracking for most artists trying to record vocals, saxophone, etc..

There are several in-depth studies that prove this, including:
