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.

I LOVE Sonix.
EASY AND QUICK, VERY VERY ACCURATE!!
I'm very happy with the experience. The Spanish translations are superb. I'm in awe!
It really accelerated my work and I was amazed by the accuracy, especially given that the video featured only non-native speakers.
It was excellent and almost entirely spot on with transcription.
It's simply an amazing resource for anyone working with the spoken or written word.
Impressed at how seamless Sonix makes editing transcripts. This is so much easier and more enjoyable than manually writing an entire transcript myself.
I loved that Sonix supports so many languages. I've been working on a project that involves speakers of 6 different languages and it allows me to translate everything into English ...
