Error meassge while using wavread and audioread

Question

0 个投票

This is a code for computing mfcc.I'm getting error as

'Undefined function 'wavread' for input arguments of type 'char'.'

When audioread is used instead of wavread it is shown that 'Too many output arguments.'

Could anybody help me resolving the issue?

 % Define variables

    Ts = 10;                % analysis frame shift (ms)
    alpha = 0.97;           % preemphasis coefficient

    LF = 300;               % lower frequency limit (Hz)
    HF = 3700;              % upper frequency limit (Hz)
