Why can I not use findpeaks with this audio signal?
Honestly not used the software much at all I understand this may be a very simple problem. My aim is to spectrally analyse an audio signal and extract its modes (frequency peaks) to spectrally model in max msp. Also if anyone knows a better way to find out the frequencies and amplitudes of peaks of an audio signal please let me know. Below is the code that will not work, I have also attached the audio sample I would like to analyze: clear; clc; close all; [audio_file, Fs] = audioread("honours_gun.wav"); findpeaks(audio_file); Below is the error it returns: Error using findpeaks Expected Y to be a vector. Error in findpeaks>parse_inputs (line 199) validateattributes(Yin,{'double','single'},{'nonempty','real','vector'},... Error in findpeaks (line 136) = parse_inputs(isInMATLAB,Yin,varargin{:}); Error in Test (line 5) findpeaks(audio_file);

findpeaks(audio_file(:,1));
or
findpeaks(audio_file(:,2));
