Hi, can you describe it more precisely?
from cwsl.
Now, I'm using this way to decode 8 bands FT8 signal :
redpitaya => cw skimmer server + CWSL_Tee => 8 processes CWSL_USBWave => Vitual Audio Cable (8 chanels) => 8 processes WSJT-X
Also my machine has Intel I7 CPU , but I found 8 processes WSJT-X started decoder at the same time, the CPU will holded 100% for about 4~6 seconds. And I compare the results of 8bands decode and single band decode, I found 8bands result often less than single band result on the same band.
So, I think to trying this way : CWSL_FILE can loop write down the wave file for each band and each 15s(wspr mode will be 112s) , I can make another script to rotated start WSTJ-X decode every wave file, I hope let the CPU don't be 100% for a long time .

Hi,
If you are using CWSL_USBWave, that is old. There is now a CWSL_SSBWave that supports both USB and LSB, and has a number of bug fixes and performance enhancements. I have done a poor job of keeping the source code updated, I apologize. You might want to try the executable here:
https://github.com/alexranaldi/CWSL/tree/master/bin
Note that CWSL_SSBWave should use maybe 1-2% CPU, not 100% !!

Hi, Alex:
Yes, I also have tried your CWSL_SSBWave,the result has a little better than CWSL_USBWave, and the main problem is not CWSL_SSBWave(CWSL_USBWave), it use rarely low CPU, but the JDTX(WSJT-X) use more CPU when decoding, specifically when 8 bands decoder working at the same time. So , my idea is use CWSL_File to record 8bands signal at the same time , and then use only one JDTX(WSJT-X) to deocode the queues of wave file.

Maybe some of you may be interested in something I've been working on that I posted recently here:

Hi andyz,
Thans for your reply and after reading your post, I'm very interested on your modify CWSL_SSBFile, but I can't find where to download
