To determine the format of a given source, start a manual recording and note the format shown on the TuneIn screen.
To play a recording, copy the file from the TuneIn folder on the device to a computer, and rename the file to give it an appropriate file extension; e.g., .mp3 for MP3 audio. The file should now be playable with VLC Media Player. (See example in Comments.)
To play with other players less forgiving of file format issues, it will need to be converted with a tool like foobar2000 or Audacity.
- This method does not appear to work with WMA streams. See if MP3 stream is available.
- In same cases TuneIn makes a recording in multiple file segments, with additional segments named -001, -002, etc.
- VLC Media Player on a computer can be used to transcode a network stream on the fly to any desired format.
- As of version 10 (October 2013), recordings appear to have been moved from open storage to protected app storage, which can't be accessed without rooting the phone.
