MP3 files are the most widely-used audio file for consumers. MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. Users can also preview M4A files by highlighting the file and pressing the spacebar.Īdditionally, M4A opens in VLC media player, Adobe Premiere Pro, Elmedia Player, Winamp, and a host of other programs.ĭeveloped by: ISO/ IEC, Moving Pictures Experts Group

For Windows users, the default program is Windows Media Player. For Apple users, iTunes is the default program to open M4A files. M4A files open in most well-known, audio-playback programs, including iTunes, QuickTime, and Windows Media Player. M4A files are smaller in size while simultaneously better in quality than MP3 files, with which it shares the most similarities, in comparison to all other audio file formats. More information about audio handling see this guide: MPEG 4 Audio (M4A) compresses and encodes audio files by using one of two coder-decoder algorithms: Advanced Audio Coding (AAC) or Apple Lossless Audio Codec (ALAC). To transparently listen to this intermediate virtual audio device in your Windows desktop, activate the 'Listen to that device' feature for it, described in this article: Interaction takes place in the actual media player. This is the device you capture with OBS, so you have your own source just for that player, so you can adjust volume and add filters as you like. For better sound control within OBS, I recommend you install a virtual audio device such as VB-Cable and configure your media player to output on that virtual audio device. The only interaction is that you can make them restart at the beginning if they are activated (scene becomes active or you click the eye button of that source).įor better interaction you probably have to use an external media player app.

The media sources within OBS are almost completely noninteractive.
