The .mpg3 file extension identifies an mp3 audio file used with Sound Studio, a Mac audio editor from Felt Tip. The file contains compressed audio encoded in the MP3 format.
Sound Studio can use the file as audio for playback and editing. The extension is uncommon today because most MP3 audio files use the standard .mp3 extension.
Open the file with Sound Studio or another MP3-capable audio program on macOS or Mac OS X. An MP3-capable audio player may also open it after the filename extension is changed from .mpg3 to .mp3; this changes the name, not the audio data.
The file already contains MP3 audio, so conversion is not normally necessary. Open it in Sound Studio and export it to another audio format if a different format is required. Renaming the file to .mp3 only makes it easier for standard MP3 software to recognize; it does not convert the file.
