Dear all,
I am a complete beginner at Mathematica in general, and at using it to try to investigate sounds in particular. I have done the following thing: Imported a short sample of spoken text using Import. I then looked at the plot of this imported object, using AudioPlot. The signal looks to be the same as how it was when I had the file open in another program (audacity).
Then I used AudioData to extract a sample from the imported file. At this point I am confused as to what AudioData is actually doing, because when I then use ListPlot to visualize the extracted data, it had quite clearly been clipped. Then when I tried playing back the data using ListPlay, it has transformed a sample that is 9 seconds long into a load of unintelligible nonsense that lasts for nearly a minute.
Can anyone give me a clue as to what is going on? Do I need to upload the sample file and notebook?
Thanks very much!
