I am missing the test signal "WashingMa​chine-16-8​-mono-200s​ecs.mp3" from the denoise example.

From the unzipped archive for "Scripts_DLSignalsAndSound.zip" I am missing the file "WashingMachine-16-8-mono-200secs.mp3".

Where can I download this file?

Thank You

Tom

We've changed this example over the releases, but everything should work as long as the demo you're reading matches with your MATLAB release. If you a) open the example by clicking the open example button on the doc page b) download files from supportfiles if the example mentions it, the file should be available to you.

I had been confused, because the first audio file used in "Scripts_DLSignalAndSound", "WashingMachine-16-8-mono-1000secs.wav", was, of course, a .wav file and I had viewed the online version of the demo, "Denoise Speech Using Deep Learning Networks" where the file "WashingMachine-16-8-mono-1000secs.mp3" was used.

Of course, the code in "Scripts_DLSignalsAndSound" the downloadable version of the DenoiseDemo, used a wav file, as mentioned, for the first sound file but the second file used was ""WashingMachine-16-8-mono-200secs.mp3", not included in the demo but was, in fact, in the Audio toolbox.

Putting the mp3 file in the local directory where I was running the demo solved the problem.

That should be included with the audio toolbox after R2019a.

The files should be in $MLROOT/toolbox/audio/samples/

where $MLROOT is the installation directory

EDIT: I take that back. That's where I'm led to believe they're supposed to be, but in R2019b, they're .wav instead of .mp3. I don't know if .mp3 versions were included in later versions or something. I imagine you could use the .wav file for the same purposes anyway.
