What's the most important part of any video project? The audio. Most audiences will tolerate poor video quality, but poor audio will lose your audience, quick. That's why today's post is about processing your audio recordings to reduce background noise. Recording a certain amount of ambient noise from wind, air conditioning, traffic, the whole world around us is unavoidable even with the most expensive equipment. The key is to make sure it doesn't distract the audience, so a old trick was to add a bit of background music to mask out the noise but not overwhelm any vocals. Computer processing and software have advanced so that now you can apply noise reduction filters to your recordings. Audacity, an open source (free) audio processor available on most desktop computers, is the first program that actually effective at doing this. So we need Audacity on the iPad... or Audacity's noise reduction functions. NCH Software's Pocket WavePad HD is the first iPad app to do this (hopefully, others will too). Read on to see how to remove background noise from your voice recordings on the iPad.
