在 MATLAB Online 中打开

Express the desired length in thems of samples (here ‘Fs’ is the smapling frequency in Hz) —

desiredLength = 17.5500;                        % Seconds
L = Fs * desiredLength;                         % Samples/sec * sec = Samples
trimmedAudioMatrix = OriginalAutoioMatrix(1:L,:)

.
