What is MP3?

MP3 is the most widely used lossy audio format in the world. It discards sound information the human ear is least likely to notice to shrink the file, which is why a typical MP3 is roughly a tenth the size of the uncompressed original. Almost every player, phone, and recorder reads MP3, which is why podcasts, downloaded interviews, and shared voice notes so often arrive as .mp3 files.

File size: A one-hour MP3 at a common 128 kbps is around 55 MB, so it uploads quickly even on a modest connection.

Transcription tip for MP3

Very low-bitrate MP3 (64 kbps or below) compresses away high frequencies, which can blur consonants like s and f. For interviews and meetings, 128 kbps or higher gives the transcription engine cleaner speech to work with.

Why convert MP3 audio with LiteScribe
