Can you recommend any software (preferably free / open source) that will help me: 1. Record interviews using a camera or a computer 2. Convert the MP3 files into text 3. Extract sound files from Video and convert the same into text? Thanks! margie Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
