Skill Profile
Signal Processing
"The observable action of manipulating audio signals — adjusting frequency, dynamics, time, and space — to achieve a desired output."
YOUR SKILLS
Problems This Skill Solves
- Muddy mixes where instruments clash in the same frequency range
- Harsh frequencies causing listener fatigue
- Dynamic inconsistency making dialogue hard to follow
- Noise interference from electrical or environmental sources

"You need to understand the maths to do this"
You can apply signal processing effectively by ear long before understanding the underlying mathematics
"AI is going to replace this skill"
AI automates routine tasks (noise removal, level normalisation) but creative and contextual signal decisions remain human
Research & Outlook
AI tools are automating basic signal processing (e.g. iZotope RX for noise removal), but creative and contextual decisions remain human. This skill is evolving, not disappearing — professionals who understand both AI tools and manual technique will be most valuable.

Growth Path
Understands what EQ and compression do and can apply presets effectively
Can diagnose a problem in audio and select the right tool and settings to fix it
Can process audio in complex, multi-layered environments in real time with minimal error
How to Practise
- 1.Take a raw, imperfect recording and practise fixing one problem at a time
- 2.Learn to remove a 50Hz hum using a notch EQ
- 3.Control vocal dynamics using a compressor
- 4.Compare the same piece of audio processed ten different ways — train your ears
How to Prove
- ·Produce a before/after audio comparison that demonstrates a specific problem solved
- ·Complete a recognised mixing course (e.g. Berklee Online, Coursera)
- ·Build a portfolio of processed audio files showing different problems solved
