- change sample to sampleRaw - add volumeSmth, volumeRaw, my_magnitude and calculate in agcAvg - remove sampleAvg, soundAgc, sampleAgc, sampleRaw, rawSampleAgc, FFT_Magnitude, multAgc, sampleReal, sampleGain, (myVals), soundSquelch from um_data interface - refactor all effects using above variables
