There is no performance issue when doing power-of-2 changes to sample rate, i.e. from 192kHz to 48kHz (/4) or 96kHz to 48kHz (/2) since there is no need for interpolation. The only time you will have an issue is if you have a program that can handle the full sample rate, e.g. CW Skimmer. Most of the digital mode programs already do internal downsampling to 11,025 Hz or 8,000 Hz so it just doesn't matter. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
