Hello! all the matlab families
I fail to do my project on real time sound signal captured through microphone
data length 131072, sampling frequency 44100Hz, mono and double data type
I need to plot the data in time and frequency domain respectively and I should write a code
that displays amplitude(max) and frequency(dominant)
