We need a command line based Linux application working like a dictating machine. We already found the open Source Software 'manauton' which goes in this direction. But it can only be used for recording Sounds. It's working with threads and a ring buffer so it's not too trivial. After starting it you can press a button and it records, another one and it pauses, yet another one to restart recording mode and so on. It's not possible to play or make fast forward or rewind. To implement these functions is your job. Especially the rewind-function should be well done because the guy recording a text want's to be able to navigate back within the sound and overwrite existing parts of his record with new text - as I said - like a dictating machine. This could be realized by playing the sound backwards while holding down a special key and when you stop holding it - it plays in the normal direction again - for example.
