Understanding Optical Compression | How to Use LA-2A w/ Fab Dupont

TL;DR

This video explains the concept of compression and how excessive compression can result in loss of dynamics and the inability to hear the desired effects.

Transcript

let me show you something that i see that confuses people here's the bass track it could use some compression i'm going to use a gray now this is what i see a lot and i see like a phenomenal amount of compression and a little bit of makeup it sounds like this and then people say oh it doesn't do much well the needle says it does quite a bit what's ...

Key Insights

• 🎧 Compression is often used excessively, resulting in a lack of dynamics and the "opto cell" being constantly in compression mode. This can lead to a loss of the desired effects and make the compressor function more like a volume knob.
• 🎛️ If you prefer the saturation and transformer sound, it's better to use a slightly distorted A2D converter with hardware equipment rather than pushing the LA2A plugin to its limits.
• 👂 When hardware is pushed, it adds a distinct heft and slower attack, which can be desired for certain effects. However, software plugins lack this initial clip and may not deliver the same characteristics.
• 🔊 Slamming the LA2A plugin or hardware excessively prevents you from experiencing the full capabilities of the equipment and results in a constant, unchanging sound, unless you specifically desire the transformer and tube characteristics.
• 🎚️ Using excessive compression can result in the loss of fluctuations and dynamics in the audio, leading to a compressed sound that lacks impact and natural variation.
• 🔌 Opto cells in compressors need fluctuations in the audio signal to properly work and deliver the desired compression effects. Flooding them with light through excessive compression prevents this and results in ineffective compression.
• 🎚️ Utilizing compression should be a thoughtful process, considering the desired effects, sound characteristics, and the equipment being used, to avoid compromising the dynamics and quality of the audio.
• 🎛️ Balancing the input gain and compression settings is crucial to achieving desired compression effects without overpowering the sound, allowing for a more controlled and dynamic audio output.

Questions & Answers

Q: How does excessive compression affect the effectiveness of a compressor?

Excessive compression floods the optic cell, leading to constant compression and a loss of dynamic changes, making it difficult to hear the desired effects.

Q: What happens when the hardware and plugin compressors are pushed to their limits?

When pushed to their limits, the hardware compressor adds a specific transformer sound and has a slower attack, while a plugin compressor lacks the initial clip.

Q: Why does excessive compression result in a lack of fluctuations and a constant compression sound?

Excessive compression floods the optic cell, making it blind to fluctuations, resulting in constant compression without dynamic changes.

Q: Does excessive compression have any benefits or desired effects?

Excessive compression may be useful if you desire the sound of transformers and tubes, but it often leads to a constant compression sound without dynamic changes.

Summary & Key Takeaways

• Excessive compression can flood the optic cell, causing it to be in constant compression and resulting in a lack of dynamic changes.

• Compression is meant to be a gain control, but excessive compression turns it into a volume knob without the desired effects.

• Hardware and plugin compressors behave differently, with hardware adding a unique transformer sound and slower attack, while plugins lack the initial clip.
