Audition says that my file is mono channel, but it's not.

Notice that i know nothing about Adobe Audition (only that it's an audio editor).

 

So, my problem is that when i import an audio file (M4A format), Audition says it's an mono channel file (which it's not).

 

I also noticed that the razor tool and other tools are greyed and i can't use them.

 

Does it have something to do with the audio format?

 

If no, then what?

    Are you importing it into the Waveform edit view or into Multitrack? Some tools will be greyed out depending on which view you are using. For instance the Razor tool is only available in the Multirack view.

    We would need to see the file itself, or a screenshot of the waveform and files panel to be able to tell you for certain.  Where did this file come from?

    Audition says it's mono because the file--at least the version you uploaded--IS mono.

     

    As Durin asks, what's the source of the file and why are you sure it's stereo?

    Perhaps you could start by telling us the source of the file and exactly how you imported it into Audition?  I've never in 40 years of audio work (and 17 years with Cool Edit/Audition) needed an info programme to tell me if something is one or two channels.

     

    Also, where are you applying your info programme?  Even with a mono signal, unless it's panned, Audition will output to two channels...but that's not stereo.

    If I'm reading that print out properly, it says the original channel count was 1, i.e. mono, but that it's playing back in 2 channels now.  This makes sense because, as I said, Audition (and most DAWs I know) play a mono file panned centrally so you get sound from both speakers/headphones/whatever.
