Hi Steve I find when I send awful noisy fluttery audio through it, the 3200 is better....
Certainly doesn't need to be barrow band for this application (well, for my application anyway) - I am thinking of increasing the bit rate even more by upping the LPC update rate to 10mS from 20mS... But there could always be variations.... g On 13/03/2016 9:46 PM, Steve wrote: > It's been awhile since I listened to 3200, so I listened to the > samples at that and 2400, and didn't really hear much difference. > Given that, I wonder if saving 900 bps (46 bits instead of 64). 2400 > is actually 2300 if you drop the two spare bits. > > Then too, I've always liked the 1200 bps sound (1175 if you drop the spare > bit). > > Just thinking of ways to make the data link more compatible with > narrow(er) band. > > > > On Sat, Mar 12, 2016 at 10:11 PM, glen english <g...@cortexrf.com.au> wrote: >> cheers David >> >> I just put a GPS receiver in one corner...$15 chip (optional) . >> >> OK that is done, I will leave it for a day to see if anyone wants >> anything else.,, >> >> >> >> On 13/03/2016 2:22 PM, David Rowe wrote: >>> Nice work Glen - good to see some more Codec 2 harwdare. >>> >>> Cheers, >>> >>> David >>> >>> On 13/03/16 10:35, glen english wrote: >>>> OK here it is, schematics, a writeup etc..... >>>> >>>> <http://glenenglish.com/2016/03/13/rpt-linking-using-codec2/>http://glenenglish.com/2016/03/13/rpt-linking-using-codec2/ >>>> >>>> >>>> >>>> >>>> ------------------------------------------------------------------------------ >>>> Transform Data into Opportunity. >>>> Accelerate data analysis in your applications with >>>> Intel Data Analytics Acceleration Library. >>>> Click to learn more. >>>> http://pubads.g.doubleclick.net/gampad/clk?id=278785111&iu=/4140 >>>> >>>> >>>> >>>> _______________________________________________ >>>> Freetel-codec2 mailing list >>>> Freetel-codec2@lists.sourceforge.net >>>> https://lists.sourceforge.net/lists/listinfo/freetel-codec2 >>>> >>> ------------------------------------------------------------------------------ >>> Transform Data into Opportunity. >>> Accelerate data analysis in your applications with >>> Intel Data Analytics Acceleration Library. >>> Click to learn more. >>> http://pubads.g.doubleclick.net/gampad/clk?id=278785111&iu=/4140 >>> _______________________________________________ >>> Freetel-codec2 mailing list >>> Freetel-codec2@lists.sourceforge.net >>> https://lists.sourceforge.net/lists/listinfo/freetel-codec2 >>> >> -- >> - >> Glen English >> RF Communications and Electronics Engineer >> >> CORTEX RF >> & >> Pacific Media Technologies Pty Ltd >> >> ABN 40 075 532 008 >> >> PO Box 5231 Lyneham ACT 2602, Australia. >> au mobile : +61 (0)418 975077 >> >> >> >> ------------------------------------------------------------------------------ >> Transform Data into Opportunity. >> Accelerate data analysis in your applications with >> Intel Data Analytics Acceleration Library. >> Click to learn more. >> http://pubads.g.doubleclick.net/gampad/clk?id=278785111&iu=/4140 >> _______________________________________________ >> Freetel-codec2 mailing list >> Freetel-codec2@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/freetel-codec2 > ------------------------------------------------------------------------------ > Transform Data into Opportunity. > Accelerate data analysis in your applications with > Intel Data Analytics Acceleration Library. > Click to learn more. > http://pubads.g.doubleclick.net/gampad/clk?id=278785111&iu=/4140 > _______________________________________________ > Freetel-codec2 mailing list > Freetel-codec2@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/freetel-codec2 > -- - Glen English RF Communications and Electronics Engineer CORTEX RF & Pacific Media Technologies Pty Ltd ABN 40 075 532 008 PO Box 5231 Lyneham ACT 2602, Australia. au mobile : +61 (0)418 975077 ------------------------------------------------------------------------------ Transform Data into Opportunity.
