How can you get the best quality sound for your videos? There are a lot of factors, and using an external microphone is one of the big factors. But another question that comes up quite often is, will a dedicated audio recorder improve my sound quality? I think it will in 95% of cases. Here’s a sample comparing the quality you get with a professional level lavalier microphone, the Countryman B6, recorded into a simple Zoom H1 audio recorder and recorded into a typical DSLR camera, the Nikon D750.
Now there are still cases where recording sound with your camera may be good enough. But if you want the best audio quality you can get, even a little $99 USD audio recorder is better than a $2000 DSLR camera.
