Understanding Sound
Learn the science and physics behind sound
Physics of sound, audio recording considerations
This page is about "understanding sound." Some sections are on a fairly theoretical and abstract level (such as Nyquist), although I've tried to make them very easy to understand. Other sections are about the practical application of audio considerations in the real-world studio recording space (such as dealing with Plosives and Sibilance). Either way, I hope some of these subjects will be of interest!
I have video links here for each subject, but there's a lot of additional contextual knowledge in the accompanying blog posts too. I don't know if I'd recommend watching the video before looking at the blog post, or vice versa. All of the blog write-ups are my own, but unfortunately I haven't had time to create my own videos for you for some of these subjects (yet). In those cases, I've picked a recommended video from another good channel.
Some of the videos in this series overlap with the larger Audio Recording series that I've shared. Let me know if there are any other subjects that you'd like to see added here.
