Hi - I was recording an interview with my iPhone 5 when after about 75 minutes into it someone called my phone. Although an m4a audio file was created (it's about 29MB in size) and I am able to copy it to my computer, my usual audio editor (AVS Audio Convertor) is telling me that the file is corrupt and it won't play in Windows Media Player when double clicked (although other m4a files do). Any ideas how I can get at the contents of this file? Cheers Ed
The first application I would normally install to see if it plays the file would be VLC Player. It supports a wide variety of formats natively using its own codecs, and might just play the file. If so, you can then play it and use the streaming option to "record" it out to a new file, or else set the input source of any other audio recording software to your sound card and record the audio as VLC Player plays it back.
Just be careful after installing VLC Player not to associate it with any of your commonly used file types or else some files that formerly opened in eg. Windows Media Player will then open in VLC Player when double-clicked. It normally shows a file association preferences dialog during setup, but if not you can do so post-setup:
Tools > Preferences > Interface > (scroll down) > Click "Set Up Associations" button.
Untick those you don't want associated > Click "Apply" > click "Save" back in main Preferences window.
Even if you have no file associations ticked, you can open the audio file from the Media menu > Open File option.
If you don't intend keeping the application, then you may also wish to de-select the following options in the Preferences:
Interface > Deselect "updates" and set album art to "manual download"
Audio > "submit last played tracks to last.fm
Let us know how you get on.
