If you are using interview, probably you are going to transcribe them. Since there is no software to do the actual transcription, it is important to find a good tool to help in the process. My suggestion is the web app oTranscribe.
It is open, free and offers the basic commands to help a regular person to transcribe audio: shortcuts for the basic commands, such as pause, rewind a few seconds and add timestamp. The software exports the transcription to friendly formats and access your audio file locally (avoiding ethical issues).
It is quite simple and quite effective!
PS: If you use and like, check if it is available on your native language. If not, contact the author (just look for his email in the first page) and help to project by translating it. It is just a few short sentences.
