Hi, sreeraj, I figured out what you meant by the math manipulations. Thanks
I based on the example of the uhd energy detector.py for modifying the output of the power squelch to use it as a trigger on burst tagger. I see that if I put on audacity 32bit float it's going to interpret the file created by the tagged file sink right. Thanks all of you :) 2015-01-04 16:03 GMT-07:00 Luis Colunga <[email protected]>: > Hello sreeraj, > > I am checking those examples, thanks.
