Having Audacity helps with Audio podcasts

I recently came across two cool features on Audacity which helped me improve my podcast episodes.


One is to amplify or normalize loudness of the recorded audio. If I have to reduce or increase my audio setting in my phone while listening to audio for songs or podcasts it irritates me. I wanted to not put my podcasts listeners through the same trouble and I came across LUFS.

LUFS!?! What?

Loudness, K-weighted, relative to full scale (LKFS) is a standard loudness measurement unit used for audio normalization in broadcast television systems and other video and music streaming services

I use Spotify for Podcasters to upload and put together audio episodes and they recommend a target LUFS of -14.

The nice thing is that Audacity supports Loudness Normalization as a standard feature. Just read the article on LUFS on the Audacity website and you have an audio normalized just right for Spotify (Loudness Normalization – Audacity Manual (


Second feature is to truncate silence when it is too long. I sometimes have a video episode that I convert to audio. A long pause in video works with visual input but does not in audio when the user is only listening and has no visual input.

The Audacity feature to truncate silence (Truncate Silence – Audacity Manual ( when it is too long really helps. I identified silent blocks longer that 1.5 seconds and reduced them to 1 second and you notice that it flows better for audio.

Industrial Metaverse, AR Engineering and VR Future

I bought my Meta Quest 2 VR glasses in 2022.

I was interested in trying it out.

I played Beat Saber and really loved it. Moving to songs with two sabers and beating imaginary blocks is fun and different from Microsoft XBox Kinect playing experience (Yes, I skipped the gaming consoles inbetween).

I explored places I have never been to with National Geographic. I grew up reading National Geographic magazines and wanted to be National Geographic photographer when I was bigger. Exploring Antarctica and Machu Pichu was fun.

The IHK München organised an XR conference where they brought it players from VR, AR, MR and the Metaverse.

Here are some of the sessions and stalls I liked:

Industrial metaverse – hype or hope

Dr. Andreas Hutter explained the different between the Social, Enterprise and Industrial Metaverse and the different investments that Siemens has already made with Digital Twins and the Industrial Metaverse. I am convinced that the Industrial metaverse is a hope.

Praxisbezogene Einblicke ins Forschungsprojekt und in die „PlanAR“ Plattform – Mehrwerte durch 3D/AR gestützte Planungsprozesse

Prof. Dr.-Ing. Volker Bräutigam explanation of the AR Engineering project where a colleague goes to a factory and then using AR glasses sets up a board and plans out the wiring was amazing.

Hochschule München University of Applied Sciences

The students of the HM showed a VR project that they had developed using Unreal and Blender. They had imagined how the world will be in the future and you could wish away things that you did not like. It was great to see them hosting them project onsite using a desktop and explaining it with a spark in their eyes. They made VR real!
