Quality Audio Matters
High quality audio is mandatory in Pro AV. Anything less, and your audience will notice, regardless of how great you video is.
Unfortunately, if you’re not an expert on audio terminology and practices it can be hard to determine the cause when something goes wrong with the sound in your video. You want to make sure your audio is:
- at the right volume
You can easily notice when these go wrong – you can obviously tell when the volume is too low, for instance – but the tricky bit is identifying the cause and fixing it.
As an example of distortion, let’s look at clipping. Clipping often happens when your equipment isn’t able to capture the peaks of your audio, and sound waves get chopped off at the top:
Many view analog clipping as “less harsh” than digital clipping, but in both cases the clipping is audible and annoying. If you need a clearer idea of what it sounds like, take a listen to this video.
There are many different things that could be causing clipping, and many different ways you could approach repairing it. Software limiters, compressors and equalizers might help, or it might be that all you need to do is change a few settings on your mixer. It takes lots of background knowledge to know the right way to deal with clipping and all the other audio problems that can plague your live stream or recording.
There’s much, much, more!
Being able to identify and fix audio distortions (or know enough to talk productively about the problems with your audio expert) is critical to your ability to produce high-quality videos and streams.
That’s why I’ve taken my presentation from Streaming Media East, a conference dedicated to the technology of online video streaming, and turned it into a whitepaper. It gives a detailed introduction to detecting and repairing audio defects, granting you the terminology and the tools you need in order to make sure you keep distortion out of your videos.
