How come I keep getting this error message?

[Image Analyst]

Does this supercede your earlier, apparently the same question? If so, please delete the earlier one. We need to keep this discussion in only one thread.

No, I haven't posted a similar question nor have I seen a similar question to this.

Edgar - the error is indicating that the variable song does not exist or has not been defined. Perhaps you meant to us the variable fur instead?

[Edgar]

I'm trying to find the 'song' variable that you mentioned I change 'fur' instead. Could you point out which line you saw it please?

The other data-clipped, sound file question was http://www.mathworks.com/matlabcentral/answers/127672-how-come-i-keep-getting-data-clipped-in-my-command-window, but if you say that they're different, that's okay.

[Star Strider]

The ‘song’ variable magically appears as an argument to var in line 35, and again in 39 and 40.

FWIW, we seem to have successfully resolved the clipping problem in How come I keep getting "Data Clipped" in my Command Window?.

The solution there was to scale it by:

s = s/max(abs(x)+1E-4);

Nothing less than 1E-4 works for some reason.

You will get that error if song+noise is less than -1, or is greater than or equal to +1. You need to either clip the data or rescale it.

[Edgar]

Would it be possible for you to show me the code that I would need to add in order to fix this issue? And where would I add it in my code?

[Walter Roberson]

Geoff's comment about using "fur" was a good point; I was looking at the warning message and thinking it corresponded to the wavwrite() that is on the screen. The hidden wavewrite() has the same problem, though: the values in fur(), being constructed from sin(), sometimes assume the value 1.0 which is out of range.

For example code see http://www.mathworks.co.uk/matlabcentral/answers/127670-warning-data-clipped-during-write-to-file-guitar-tuner-code
