(E.g., for all I know at this point, the source file may contain DTS surround sound for TV playback which would be "natively" incompatible with most QT-based media apps.) While QTX/QT7 based media players expect MPEG-4 audio, such file containers can be created by third-party encoders using other audio compression formats.

I assume that your use of "MP4" here refers to the download of an "MP4" file container but does not confirm that the file does, in fact, contain some form of MPEG-4 (AAC) audio. I generally recommend posting either images containing a breakdown of data compression information detailing how the file was created or the uploading of a sample file for examination. Unfortunately, the information given is incomplete and/or ambiguous at this point.

So, until next time, this is Gary with MacMost Now.I downloaded a video in MP4 format, but when I tried to open it in quicktime player, it has no audio. For anything else then you're going to want to go into a more advanced audio editor, like for instance garage band is perfect for that kind of thing. Now thats going to come very useful if you have some audio that you want to bring into other some project, like,using iMovie or Keynote or even Pages. You just have the basics of being able to trim things. So you don't have all the fancy options like being able to export as other file types or being able to adjust the audio, things like that. I can do, for export, Shift Command S and then Command Z for Undo, Command T for trim again, and I'm back to selecting the third portion there and Return, Shift Command S, export it etc. I'm just going to hit Return and thats the same thing as accepting the trim. So, you see here I can actually even use keyboard shortcuts for everything.

It's a manual process but it's pretty quick. Then I can go trim again and grab the next portion. I can do Command+Z or Edit Undo Trim and get the original back. Well I just trimmed down and exported the one part.
Now, say I want to split an audio file into several parts. Now I can go to file and export, and export out just that one portion as a new audio file.
Once I get exactly what I want I click the trim button and now I just have that one portion of the audio. To trim I basically grab the left side there, go to where I want start, grab the right side right there. Its pretty compressed so now I want to grab the right side and drag it over here to the right so now I can see it a little bit better and its easier for me to select. Now to trim this audio what I would need to do is go to edit and then trim. I'm going to just drag and drop that onto Quicktime player and it will open up in a very simple player interface and I can play it. So here I've got an audio file right here.

And I get a lot of questions from people that want to know how to trim a little bit of sound from the beginning or end of some audio or to break up an audio file into several parts. Well you can also do the same in audio, you can trim audio. So on Episode 647 I showed you how you can use the Quicktime player in Lion to edit video. On todays episode let me show you how you can trim audio using Quicktime player. Video Transcript: Hi this is Gary with MacMost Now.
