Fundamentals
Waves, frequency, amplitude, phase, decibels and digital audio: the essential language of sound.
WB STUDIO PRESENTS · OPEN AUDIO EDUCATION
The knowledge behind sound.
Learn to listen critically, understand what your meters tell you and explore audio technology. A free academy for curious minds, students and professionals.
No registration. No barriers. Technically grounded.

OUR IDEA
Listening is the beginning. Understanding takes us further.
A waveform, a LUFS reading and a spectrum curve each tell a different story about the same signal. Learning audio means understanding what each instrument measures, what it cannot tell us and how that relates to what we hear.
WB Audio Academy is an open learning library: from simple questions to loudness measurement, production and analysis. The knowledge does not depend on using any particular tool or software.
EXPLORE THE KNOWLEDGE
Six ways to discover audio.
Learning resources will be organized by topic. Category pages will be enabled as complete lessons become available.
02
Measurement & analysis
VU, RMS, dBFS, LUFS, true peak and LRA: what each meter measures, how to read it and its limitations.
03
Audio processing
Equalizers, filters, compressors and limiters. What they change in a signal and when they are useful.
04
Production & mastering
Recording, mixing, monitoring and preparing audio using both technical and listening criteria.
05
Radio & streaming
Transmission, codecs, quality, loudness and continuity. One application of audio knowledge, not its only destination.
06
Standards & guidance
References such as ITU-R BS.1770 and EBU R128, from core concepts to real-world practice.
START WITH THE BASICS
Your first learning path
A sequence designed to make the concepts clear before opening a meter. Individual lessons are in preparation.
Learning path in preparation- 01
What is sound?
From vibration to perception.
- 02
Decibels made understandable
What they express and why scales are logarithmic.
- 03
How digital audio works
Sampling, quantization and signal levels.
- 04
From VU meters to LUFS
Why audio needs different kinds of measurement.
- 05
Your first measurement
Read a meter with context and critical judgment.
ONE IDEA TO TAKE AWAY TODAY
A peak does not tell the whole story.
Two recordings can reach similar peak levels yet feel very different in loudness. Good measurement starts with knowing which quantity is being measured.
Peak
Describes a maximum signal amplitude. It does not, by itself, describe perceived loudness.
Loudness
LUFS measurements estimate loudness using standardized algorithms and defined time windows.
Variation
What happens over time matters too: a single number may hide the changes throughout a recording.
LEARNING BY DOING
WB Audio Lab
Our future lab will bring together reproducible experiments, test signals, screenshots and comparisons. We will explain the principles first, then show how to verify them with available tools and, once validated, WB Studio modules.
Lab in preparationExperiments with context, not unexplained numbers.
Each exercise will document its input signal, method, tool, limitations and conclusions. Visual simulations will never be presented as real measurements.
WB / EXPERIMENTS / 001OUR COMMITMENT
Open, independent, careful.
Open
Core educational content will be freely available, without mandatory registration.
Independent
We teach concepts that transfer across different applications, equipment and platforms.
Verifiable
Technical sources and clearly labeled experiments, with no unsupported claims of certification.
SOURCES FOR FURTHER LEARNING
Knowledge backed by references.
These technical publications are starting points for understanding loudness measurement, not endorsements of WB Studio.
FREQUENTLY ASKED QUESTIONS
Before you begin
Do I need prior experience?
No. The first learning path will start with foundational concepts and require no technical background.
Is the academy only for radio?
No. Radio and streaming are included alongside fundamentals, recording, production, analysis and standards.
Must I install WB Studio?
No. Articles stand on their own. When a lesson uses software, we will explain the options and clearly state each tool’s development status.
WB STUDIO · AUDIO ACADEMY
What we learn can live on.
This academy is part of a lasting body of shared knowledge dedicated to Walter, The Magician. We aim to honor that legacy with useful work and careful documentation.
