skirt sharpness is function of BOTH sample rate and buffer size. the "resolution", if you will, of the filter specification is (sample rate)/(buffer size).. so 48000 samples/second/2048 samples/buffer gives you a resolution of about 24 Hz. 8000 samples/second at the same 2048 samples/buffer gives you a resolution of 4 Hz. (at the expense of 250 millisecond or maybe 500 millisecond latency through the system) >-------------- next part -------------- >An HTML attachment was scrubbed... >URL: >http://mail.flex-radio.biz/pipermail/flexradio_flex-radio.biz/attachments/20070215/e4dc0a92/attachment.html > > >_______________________________________________ >FlexRadio mailing list >[email protected] >http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz >Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ >FlexRadio Homepage: http://www.flex-radio.com/ > >FlexRadio Knowledge Base: http://kb.flex-radio.com/ James Lux, P.E.
