I have the format of start time for ex: (format minutes, seconds, milliseconds) start time = '9,36.486' end time = '12,02.749' how can I extract the sound part exactly between those times from a wav file ? should I convert start and end time using datevec ? and how to extract those from the wav file (ex. audioread ) thanks a lot !!

iTimeS = '9,36.486';
fTimeS = '12,02.749';
iTime = sscanf(strrep(strrep(iTimeS, '.', ''), ',', '.'), '%g');
fTime = sscanf(strrep(strrep(fTimeS, '.', ''), ',', '.'), '%g');
info = audioinfo(File);
sample = round([iTime, fTime] * info.SampleRate);
signal = audioread(File, sample);
