Hi,
I am uploading an audio signal of 3 seconds in matlab, but after uploading it is showing 0.5 seconds audio and the signal is totally change. How can I change the time, so that I can listen full audio of 3 seconds and implement other operation on my 3 seconds audio. Please guide me.
Thanks in advance.

Please attach norway.wav
You might need to zip it and attach the .zip

Hi Wave file is not uploading here.
Can you please tell me which one is the correct command for taking sum of 10 imfs and residual? I am comfused in this.
s= plus(sum(imf(5:10)),residual);
or
s= plus(sum(imf(5,10)),residual);
or
s= plus(sum(imf(5,10,:)),residual);

Zip the audio file. Upload the zip file.
I do not know what an imfs is in this context?
Some of what you wrote suggests that you might have 6 elements, not 10. Elements 5, 6, 7, 8, 9, 10 is a total of 6 elements.

You need to tell audiowriter that the sample rate, FS, is 8000.
