Hi. This is a transcription job of 3 hours of Mp3 recordings of interviews. The quality is pretty good, but you may need to turn up your volume to full to hear the interviewee well. You would need to transcribe both the interviewer and interviewee, indicating who is speaking at all times and putting a line space between each change of speakers. Keep in mind that although there are three hours of recorded time, it will take you more time than that to transcribe.
