YouTube is all about the video so perhaps it's understandable that most people forget about something equally important, the audio. Most viewers will put up with choppy and poor quality video as long as the audio track is good or at least not horrible.
Awkward silence, pops, loud noise and so on will make people close your video a lot faster than poor video quality.
This is hardly a secret and YouTube has been offering a way of improving the audio part of a video, that goes well with its video editor, and now it's updating the tools as well as offering more music to add to your video.
"We introduced AudioSwap to let you replace a video’s soundtrack for free with a song from our library of thousands of tracks. With more of you using AudioSwap and giving us lots of feedback, we have some cool improvements to share today in YouTube Audio Editing," YouTube announced
One immediately noticeable improvement is the amount of music available, YouTube boasts that there are 150,000 tracks now and more are being added. With so many of them, finding the right one can be tricky, but the categories should help and YouTube's featured tracks for each category are a good place to start.
There are also more options when adding the music to your videos, you can have it played in the background, barely audible, or have it completely replace the original audio track.
The Audio Editing section has been revamped as well to make it easier to understand and use.
Along with the video editor, this feature is a great tool for improving the quality of the vast majority of videos on YouTube, which are shot with phones or cheap cameras by regular people with no experience with either video editing or filmmaking.
