Re: Cached data

Yes,

the maximum cache size is 480MB, I'll increase this to the greater of 480MB and 1/8 installed RAM, so if you have 8GB it'll be 1GB, if you have 16GB it'll be 2GB etc.

Depends on the same rate / bandwidth. There may be a maximum cache size which I can increase.

I'm not getting the result with the data cache that I expected...

If I set the cache to 30s...and record for 30 seconds I should get a file with 60 seconds of data, correct? What I see is only 42 seconds. When I look at the logfile I see: Cached data...12 seconds. Should that not be 30 seconds?

Could someone play with this and report back...

Hi Simon, Larry.

I can confirm that when I attempt to set a recording cache when setting up a recording preset under the data recording options and tick the box for the "cache" drop down, whatever value I select, no data is cached. When I replay the IQ file, the start time remains the same as when I hit the preset record button and I've checked the audio on the recordings, and it has not pre-fetched audio from before I hit record (in case it had cached data but not updated the time readout to allow for any cached data).

This is for data, not audio recordings. I'll check it's still working...

Is there something else that needs to be turned on? I'm not seeing any cached data in my recordings.
