When I call designAuditoryFilterBank, I get an error that says "Undefined function or variable". This function should be from the audio tool box which I do have installed, so I don't know why Matlab doesn't recognize the function.
The designAuditoryFilterBank function is available from the MATLAB R2019B release version. If you are using an older version, the function will not be recognized by MATLAB. You can upgrade to the latest version of MATLAB to use the function. If you are using MATLAB R2019B, try reinstalling the Audio Toolbox to solve the issue.
