Unable to resolve the name 'dsp.priva​te.designW​indow'.

I have received the following error when I try to run the auditorySpectrogram function.

Can you please help?

Unable to resolve the name 'dsp.private.designWindow'.

"win = dsp.private.designWindow(params.WindowType,params.WindowLength,params.Datatype);

There does not appear to be any auditorySpectrogram function in MATLAB itself. There is an auditory spectrogram Simulink block, https://www.mathworks.com/help/audio/ref/auditoryspectrogramblock.html

MATLAB offers designAuditoryFilterBank and there is the example function extractAuditorySpectrogram https://www.mathworks.com/help/audio/ug/ai-for-speech-command-recognition.html#mw_28339f65-aca9-4bc8-bfa3-8c27f666fe69_sep_mw_rtc_SpeechCommandRecognitionUsingDeepLearningExample_M_20BDA5AD

There appears to be a function dsp.internal.designWindow

That is correct, the auditorySpectrogram function was created by a user.

My main question is why am I receving "Unable to resolve the name 'dsp.private.designWindow'" when I have the DSP System Toolbox installed on my latop? Also, when I apply "which dsp" command at the command line, i get " 'dsp' not found" error.

We have no information about what auditorySpectrogram is doing. It might be calling dsp.private.designWindow directly. Perhaps it was written for an older version of MATLAB in which (hypothetically) dsp.internal.designWindow as formerly known as dsp.private.designWindow .

[Theodros]

Thank you! The auditorySpectrogram function uses "dsp.private.designWindow" function.

Replacing that with "dsp.internal.designWindow" has fixed the problem. With this, i'd like to close this request as complete.

Thanks a lot for your help!
