Yes, your filter shape factor (may) have changed for the worse depending on the DSP buffer size you used for 96K as opposed to 192K. The advantage is that you have reduced the latency by increasing the sampling rate.
See appendix A in the FLEX-5000 Owner's Manual for the technical explanation. http://support.flex-radio.com/Downloads.aspx?id=246 -Tim -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Jim Sent: Wednesday, July 22, 2009 9:05 AM To: [email protected] Subject: [SPAM] [Flexradio] audio sample rate and buffer size This morning I increased the audio sample rate in powersdr for my flex 5000a from the default 96000 to 192000. I noticed that the audio quality seemed to increase a bit and of course the panadapter frequency slice shown was wider. Are there any adverse affects caused by increasing the audio sample rate? Also, in the vein of more is better. What are the tradeoffs of increasing or decreasing the buffer size? I am using a dell inspiron 530 running a quad core processor so I am thinking I should bump up all the settings possible to make use of this fast hardware.
