PES 022: Georg Holzmann

My guest is Georg Holzmann, founder of Auphonic. He lives in Austria.

We went deeper than usual into audio processing including:

• Machine learning
• Compression
• Noise reduction
• Loudness levels
• Handling multiple voices
• Crossgating

We spent time going line by line through the fascinating Audio Processing Statistics that Auphonic provides after you process a piece of audio. During the show we discussed the screenshot shown here, which contains these data:

• Programme Loudness
• Max Peak Level
• Loudness Range (LRA)
• Max Momentary Loudness
• Max Shortterm Loudness
• Leveler Gain mean
• Leveler Gain min
• Leveler Gain max
• SNR mean
• Background Level mean
• Signal Level mean

I also asked him about how voices with different EQ appear different in loudness, as well as if there are cases for which I should process the audio a bit first before using Auphonic.

We appreciate you hanging with us, Georg!
