Yes, it will only show a picture of ST But if interested i have Pentium I 100 Mhz  and a Cyrix at 66Mhz

I don't know yet. There are 192 kHz cards available (at a very low price even) but I have no idea yet if they are any good.Which sound card will work with the raspberry version ? A good sound card USB ? 192 khz for MPX signal Thanks This might work (NOT TESTED!!!): http://tweakers.net/nieuws/94783/wolfso ... ry-pi.html

FX-4300 vs. a fast i3:So i3 (2 CORES) to be better than 6 core CPU is the most stupid thuing i`ve ever heard ! http://cpubenchmark.net/compare.php?cmp ... cmp[]=2351 Most important part: Single Thread Rating: FX-4300: 1411 i3: 2228 - so i3 single thread is 58% faster! CPU Mark FX-4300: 4639 i3: 5576 - so i3 in TOTAL is still 20% faster! The AMD also uses a lot more power. It is also older and cheaper, so maybe not a very honest comparison. But a dual-core i3 can definitely be faster than a quad core AMD. |

Ah. That's going to be a problem for that card as well I suppose

But a dual-core i3 can definitely be faster than a quad core AMD. I was comparing to i3-3220T, which is downclocked (and only 35W!). Additionally, as I said - FX4300 is NOT a true 4 core chip. It has 2 modules (2 integer and 1 floating point units per module). So in total it actually has 4 integer units and only 2 floating-point capable units. Hence, FPU-wise it's a dual core!

it`s 4 cores, but two by two are sharing same recources . It`s NOT like 2 "virtual" cores. They are phisically there , but share the L3 and L2 cache. But it`s different from what Intel "do" with these virtual threads . note i said threads , not cores ! Here is the explanation http://wccftech.com/review/amd-fx-8350- ... or-review/ |

They share not only CACHE (shared CACHE is a common thing in CPUs). They have 2 modules 2 cores each (In 4 unit CPU's, which are marketed as cores). But in total only 2 FPU units. Instead of 4 as in regular CPU's. So are they 4 core CPU's? Yes integer-wise and no floating point-wise. Of course Windows and any other system will show you 4 threads. As in i3 for example, which is hyperthreaded dual core. A real problem with those CPUs is that the OS doesn't recognize its modular structure. So the OS thinks it has regular 4 cores. Which is not true (in normal scenario 1 core = 1 FPU and 1 integer, in FX 1 module = 2 cores for which there's 2 integer and only 1 FPU). This is why some power is being wasted on CACHE storing the data for floating point operation (system thinks there are 4 FPUs). It's actually some kind of multithreading that the OS is not aware of. Also it tends to perform slower in Windows than in Linux (according to benchmarks, however I didn't test the last one myself). Vishera uses exactly the same module structure as Bulldozer, and looks like this:  See: 1 module = 2 integer units, 1 floating point (FPU) - and those share 2048 kb CACHE. |

This explains a lot of complaints that I have seen from AMD users who mentioned getting very different multithreading behavior when they restart Stereo Tool. |

Ah. That's going to be a problem for that card as well I suppose " And some important notes: I haven't included the mmap patch, this is already supported in the upstream kernels but currently disabled by default. To enable mmap support add the following line to config.txt: dtoverlay=i2s-mmap " And now stereotool is starting up, but the cpu usage is 50% constant. I only want to use the FM part of the software. I want to generate ST+RDS signal. |
