Sonix transcribes your MPA file and exports it as SRT subtitles that you can use with any video platform or editor.
MPEG-2 audio stream for digital media
MPA files are audio files compressed using the MPEG Layer II compression codec to reduce the file size while only slightly impacting the overall sound quality. Digital music and high quality audio programming such as podcasts are usually compressed for web users with this format. The MPA file format uses the MPEG-2 specification for compression to reduce file size for better transmission across the internet.
