This one is controversial – personally I don’t do it, I always prefer to use Audacity to remove background hiss. See this Audacity screencast tutorial for instructions on de-noising, range compressing and editing your narration using Audacity.Audacity is a great open-source tool to remove ambient noise so you won’t get a background hiss.

Camtasia Studio on Windows is one of the few screencasting programs that can automatically remove ambient noise (BBFlashBack on Windows and Camtasia Studio and ScreenFlow on Mac can’t). Remove ambient background noise and clean the audio If possible buy an expensive low-noise fan for your computer like the Noctua NF-R8. We discuss mics like the CU01, SM58, Plantronics 550, sE2200A and ATM73a in the Handbook. Use USB mics – the motherboard’s electrical noise won’t get into your audio. Avoid cheap 3.5mm jack mics that sit on your head – these tend to be the lowest quality mics and their 3.5mm connectors induce electrical noise into the signal. Keep breaths shallow, quick breaths in or out cause a lot of air to rush over the mic which sounds very noisyĪ better mic will tend to record your narration with greater depth and quality. Don’t run any other programs if possible so the CPU isn’t under load – that way the fan is less likely to run fast which tends to make it louder. For laptops use an external mic so you can get away from the laptop’s fan. Move the mic a long way from the PC’s fan. Wait for quiet times of the day – traffic, aeroplanes and birds can be quite obvious in the recording. Turn off all other equipment including mobile phones, fridges and fans. Isolate your recording environment – be in a room by yourself with the door shut and windows sealed.
Always strive to record clean, clear audio: This topic is discussed in more detail in The Screencasting Handbook.Īny audio engineer will tell you that a poor original recording is the hardest thing to try to improve.

It doesn’t matter how swish your graphics are or how carefully you’ve planned your script – if your audio is hissy, full of pops and breaths and background sounds (like traffic!) then the listener will be disappointed. One of the biggest problems with screencasting is poor audio quality.
