Sample Rates and Performance

Input sample rate always shows the detected sample rate coming in from your

optical cable. If this value varies continuously, please check if you configured the

input correctly (Did you choose ADAT as input and falsely connect it to an S/PDIF

device or vice versa?).

What will be displayed as

Output sample rate depends on the settings in the General

page. If you chose LAGOON as clock source, Output sample rate should always

match the frequency you set in the LAGOON Tools General page. If you chose

Optical In, Output sample rate should be the same as the one you are feeding in into

the optical input of your LAGOON card. If you chose

ADAT Sync In, the sample rate

at the output will match the word clock frequency from the ADAT Sync In interface.

DSP load shows the percentage of the DSP power which is currently required by the

system. This depends on which format (ADAT or S/PDIF) you are using and if many

repeated PCI transfers have to be carried out.

The percentage of

PCI-repeated transfers indicates if the PCI bus is behaving as it

should. In most systems it should only display a few percent. If you see a large

number of PCI-repeated transfers (up to 10 percent and above), then perhaps you

have an older mainboard in your PC that is not suitable for multimedia demands.
