Tips to achieve optimal interview recording quality
A few tips are listed below to assist when recording interviews for transcription. The recording/audio quality will impact the quality of your transcript.
Set the recording device to record in an uncompressed file format such as “.wav” (Windows) or “.aiff” (Mac). In a quiet environment with acceptable acoustics, file formats such “.mp3” or “.wma” would also be appropriate.
Environmental noise – such as that of air-conditioners, fans, radios, TVs, passing vehicle and people traffic – can impact on how well voice input is heard and transcribed. Where possible, switch off devices and equipment that are a potential source of background noise that could impact on the quality of the recording.
Remind your interviewee to increase voice projection in noisy environments.
Place mobile phones as far as possible from the recording device to exclude or minimise interference.
In an extremely noisy environment such as a restaurant, it would be best to make use of a lapel microphone. Alternatively, place the recording device as close as possible to your interviewee.
