The Anatomy of an Audacity Waveform

Waveforms are where we spend our time as podcast editors and it’s important to know enough about a waveform to be comfortable editing it. Audacity waveforms are digital representations of the audio that’s been recorded or imported into Audacity. Analog audio recorded through a microphone has to be converted to digital audio before Audacity can do anything with it. USB mics, mixers, and portable recorders like the Zoom H6 do this analog to digital conversion prior to giving it to Audacity to be edited. Let’s take a closer look…

The Audacity Play-at-Speed Toolbar

The Play-at-Speed tool in Audacity can save you time in your podcast editing. It’s versatile in that it gives you a way to speed up the tracks you’re editing so you don’t have to go through them in real time. It also gives you the ability to slow down a track if you need to isolate a section of audio that needs special attention.

The Anatomy of a Track in Audacity

Let’s talk about the anatomy of a track in Audacity. What’s all the stuff in the track header and what do we need to know about it? How do I change the scale and what do the sliders in the track header do? How do the settings in the track header affect my exported audio?

Product Review: Neewer ZC-10S Lighting Kit

When I started doing video lectures last February, one of the immediate challenges I faced (in addition to learning how to make videos in the first place and feeling comfortable in my own skin) was how to do lighting. I’m not the sharpest knife in the drawer but I’ve figured out two important things when making a video: good audio and good lighting are essential. If I have good audio and decent lighting, people are more prone to watch even if the video I’ve created isn’t the best.

This video is about my lighting solution. I’ve been using the Andoer Softbox Lighting Kit from the beginning but though it’s a great product (the link is below) it was too big for my small room. So I started doing some research and came across the Neewer ZC-10S Lighting Kit. This small, dimmable LED kit is perfect for my recording environment and it didn’t break my budget.

If you’re doing videos from a small room and you’re on a budget, these Neewer LED lights might be for you. Here’s the links to what I talk about in this video:

Thanks for watching!

High-Pass and Low-Pass Filters Explained

Let’s take a few minutes to talk about the high-pass and low-pass filters in Audacity. High-pass and low-pass filters are an effective way to attenuate unwanted frequencies above or below a set point that you determine. It can be another way of eliminating or reducing unwanted noise in your podcast.

How to Use The Zero Crossing Tool in Audacity

Do you have questions about how to use the Zero Crossing Tool in Audacity? The Zero Crossing Tool ensures that the end points of the audio waveform you’ve selected are at the zero, or silent crossing point prior to editing the selection. This helps eliminate the possibility of popping sounds which can result from not using the Zero Crossing tool.
