Part of the series: general.

Here's a view of my voice. The bright spots at the bottom of the image are my voice, and the bright burst at the top is a click caused by saliva.

Here's me inhaling. Notice how sparse this is compared to my voice.

One thing I fail to mention in the episode is that there are network monitors that render network activity as a spectrogram, too. If you don't have a Wi-Spy, it's worth looking at.

I gave it a go.

I had no idea this was in audacity. I was very excited to know there maybe a way to remove the hum of my HVAC but this still isn’t possible. This was a nice short rabbit hole to wonder around in for a day or two. I learned more about audio frequencies and how to interact with them in audacity. Great show.

What a great tip

Hi Klaatu just wanted to say I was intrigued by this podcast and took a note to try this out when I get a spare 5 minutes. I just opened my most recent show into Audacity and selected Spectrogram view. The results are amazing. Any involuntary noises become so much more visible making them very easy to pick out and remove. I will be sure to use this in future shows. Thanks again for another brilliant show. Cheers MrX
