TheAncientOne Posted January 22, 2008 Report Posted January 22, 2008 Got a message today about this. Price seems to be about $150 for the board.http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=SYMP_SOUNDBITEI think there may be Blackfin boards in the same price bracket now, but I think affordable DSP seems to be coming.

dj3nk Posted January 23, 2008 Report Posted January 23, 2008 What about the AL3101 ? It costs under 10 $. Quote
TheAncientOne Posted January 23, 2008 Author Report Posted January 23, 2008 What about the AL3101 ? It costs under 10 $.That's for a chip. The AL3101 evaluation board from the maker costs $225. http://www.wavefrontsemi.com/products/AL3101pop.html#productevalIt's also peaked at 50 MIPS, the Freescale quotes 180 MIPS. The AN3101 is aimed more at certain types of FX. It's done very good work in 'Miss Parker'. The 1000 off price for the AN3101 is around $4. The 1000 off price for the DSP56371 is around $9.Basically different league devices. What I really want is a next generation version of the Chameleon, not a stompbox. Quote
Doug Wellington Posted January 25, 2008 Report Posted January 25, 2008 I ordered the uclinux blackfin stamp board once I saw that it was used in the original Looperlative. Since I work with linux during the day, it was/is a relatively easy learning curve... There's also a bare pcb available for $70 - check out http://www.blackstamp.netI'm also interested in a next-generation chameleon type of device...Doug Quote
gpmacklin Posted January 25, 2008 Report Posted January 25, 2008 What I really want is a next generation version of the Chameleon, not a stompbox.I'm with you on that one. I remember back before the old Chameleon forum went defunct there was talk of creating an open source variant of the Chameleon. I was happy to see an email floating around in my inbox from Mr. Maddox bringing light back to that topic. Quote

smashtv Posted January 25, 2008 Report Posted January 25, 2008 http://rubidium.dyndns.org/pipermail/fpga-synth/Trying to understand what is missing here, how does this FPGA synth list archive link relate to a discussion on DSP eval boards?Trying to follow along, keep on same page etc. Help me out with a little more than a one liner please.BestSmashTV Quote
Ashiman Posted January 25, 2008 Report Posted January 25, 2008 well, an fpga can be even better than a dsp, cause xilinx dev tool is absolutely free, and its easier to migrate from one platform to another , that motorola sohuld be considered obscure imho.here is a good link for starters with integer arithmetic http://www.diyaudio.com/forums/showthread.php?s=&threadid=113341fpga can even synthetise floating point units tho.

At the same time, an FPGA is worse than a DSP because it is an empty container! You have to do a lot of work to get an FPGA to do anything, whereas with a DSP, it already does what it does, you just write code for it...Doug Quote

stryd_one Posted January 26, 2008 Report Posted January 26, 2008 Mmmm, super chameleon. I think you just have to set off a nuke near it's island and then it grows or something ;) Quote
audioworld Posted March 11, 2008 Report Posted March 11, 2008 I just checked the schematics of this Freescale SOUNDBITE DSP board,and in addition to USB it does have I2C and SDI/SPI interfaces.with the free development kit, one can program in Assembler or C.do you think: would there be ANY chance that one could connect this directly to the MB core IIC Interface (J4)?sounds like an incredibly useful combination to me without a PC/MAC:3 stereo in3 stereo outmicrophone input+ a couple of buttons and rotaries via MB...-))) Quote
stryd_one Posted March 12, 2008 Report Posted March 12, 2008 would there be ANY chance that one could connect this directly to the MB core IIC Interface (J4)?Yes. A good chance, I'd say. Quote
audioworld Posted March 12, 2008 Report Posted March 12, 2008 thanks, stryd,I'll dive into that one (...mhh...thinking about my very basic I2C programming skills from 15 years ago...) Quote
Echopraxia Posted March 13, 2008 Report Posted March 13, 2008 Sounds like a great idea! Now I need to find out how to get a UAD card running in a midibox. Quote
Doug Wellington Posted March 13, 2008 Report Posted March 13, 2008 The UAD-1 is quite interesting - it's actually a chip from a video card. There seem to be quite a few projects using graphics hardware for general purpose computation... Quote
Ashiman Posted March 13, 2008 Report Posted March 13, 2008 excuse me , uad stuff is no ordinary video card, just like this isnt the yesterdays vaporware thread. http://en.wikipedia.org/wiki/Chromatic_Research Quote
Doug Wellington Posted March 13, 2008 Report Posted March 13, 2008 excuse meOK, you're excused, you can leave now... ;)uad stuff is no ordinary video cardI didn't say it was a video card...I said it uses a chip from a video card... Quote
Ashiman Posted March 13, 2008 Report Posted March 13, 2008 I'd look into ps3linux if I'd want to learn parallel audio processing -.- Quote
Doug Wellington Posted March 13, 2008 Report Posted March 13, 2008 I'd look into ps3linux if I'd want to learn parallel audio processing -.- Hmmm, wouldn't I have to buy a PS3 for that? For that kind of money, I could buy the Blackfin board AND the SoundBite or Spartan board...And what if I wanted to learn serial audio processing...? ;D Quote
Ashiman Posted March 13, 2008 Report Posted March 13, 2008 actually, the good serial connection looks to be: 1. get the freescale (many ppl over synth-diy list bought it ) 2. detach the low quality codec 3. insert TAS3103a or TAS3108 in its place you can do the memory based FX on soundbite and filtering on the TAS and lot else.

gpmacklin Posted March 14, 2008 Report Posted March 14, 2008 The Soundbite has forum in case anyone is interested:http://www.qix.synth.net/Forum/ Quote
Ashiman Posted March 15, 2008 Report Posted March 15, 2008 http://www.prodigy-pro.com/forum/viewtopic.php?p=317541#317541Dale116.7 tells you what is the problem with soundbite ~ why he rolls his own Quote
DrBunsen Posted April 11, 2008 Report Posted April 11, 2008 Hmm, Freescale/QiX board looks nice ... 8 channels of audio IO... can't figure out what the CPU on it is though. Being Freescale I assume it's a 68k or PPC derivative, but can anyone give a definitive answer? Quote
Doug Wellington Posted April 11, 2008 Report Posted April 11, 2008 There is no CPU... The guys on the Qix list are using the ColdFire M5251C3 evaluation board for control via SPI... (Of course, the only price I've seen on the ColdFire eval board is over $900, so there goes your cheap development platform...) :o ::)DougAll the more reason to stick with the Blackfin! ;D Quote
