Tips to achieve optimal lecture and speech recording quality
A few helpful tips to achieve the best possible recording of a lecture or speech where professional sound equipment and sound engineers are not available to assist.
- In noisy environments set the recording device or equipment 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.
- Position the microphone at the recommended distance from the speaker but some distance from any potential source of interference.
- Environmental noise – such as that of air-conditioners, fans, passing vehicle and people traffic – can impact on how well voice input is heard and transcribed. Where possible, position the podium away from open windows and doors and a distance from the audience.
- Place mobile phones as far as possible from the recording device to exclude or minimise interference. If appropriate, request audience members to switch off their cellphones or set their phones to silent mode.
