Here I have a question regarding data type conversion in GRC. Since the
output of audio source is analog signal. So, I am going to encode the
output of audio source(float, -1 to +1 ??) to digital bit streams(byte)
digital signal Processing later on. But I found there’s no ADC or
GRC which could properly convert float: -1~+1 to Byte: 00~FF. Is there
way to achieve that?
