Re: [softrock40] Re: USB Audio device
- Given a good 192KHz vs 48KHz there is an advantage to 192KHz, when you decimate the signal down to narrow the bandwidth in the software if the proper algorithms are used you gain increased dynamic range and S/N ratios the more you decimate. But of course the benefits must be compared to the increased cost not just in dollars but also in term of CPU time required.That is why a Mercury card while it only has a 16 bit A/D with 14 bit accuracy because it samples at 60MHz or more that with the decimation required it ends up having better quality than a really good 24 bit card.On Tue, 31 Aug 2010 21:33:34 -0500, Tom Hoflich <km5h@...> wrote:Dan, I think you are exactly right. I think the 96 and 192Khz thinking goes back to when we did not havethe frequency agility of the Si570. If you are crystal bound, the wider sampling does make sense.73, Tom
