Learn Audio Engineering

From microphone to finished file, understand every link in the chain.

Free to start. Built from a single prompt. No credit card.

Audio engineering is the technical side of capturing and shaping sound: choosing and placing microphones, routing signals through preamps, interfaces and consoles, setting healthy levels, and recording clean takes that are easy to mix. It covers concepts like signal flow, polar patterns, phase, sample rate and bit depth, plus how a room's acoustics affect what you hear. Learnr builds a personalized audio engineering course from one prompt, with short interactive lessons that explain the tools and give practical recording exercises.

How to learn Audio Engineering, step by step

Learn signal flow. Draw the path from source to microphone, cable, preamp, interface, DAW and back out to speakers or headphones. Most recording problems are solved by checking each step of that chain in order.
Understand microphones and polar patterns. Dynamic microphones handle loud sources and need no phantom power, while condenser microphones usually need 48 volt phantom power and capture more detail. Learn cardioid, omni and figure-8 patterns.
Set gain and recording format. Set preamp gain so the loudest parts peak well below clipping, record at 24-bit, and choose a sample rate such as 44.1 or 48 kHz and keep it consistent across the project.
Practice mic placement. Move a microphone closer or farther and off-axis on vocals, acoustic guitar and amps, listening for proximity effect and room sound. Use the 3 to 1 rule to reduce phase issues with multiple microphones.
Treat your room and monitor accurately. Reduce reflections with absorption near your recording spot and listening position, and set speakers in an equilateral triangle with your head. Short Learnr lessons with streaks help you build these habits steadily.
Edit and prepare tracks for mixing. Comp takes, trim noise, add short fades to avoid clicks, label tracks clearly and export consistent files for mixing or collaboration.

What you'll learn

Trace signal flow from source to DAW and back to speakers

What's inside your Audio Engineering course

A sample path Learnr builds for Audio Engineering. Your real course adapts to your goal and level.

1. Sound, decibels and signal flow
2. Microphones and polar patterns
3. Interfaces, preamps and gain staging
4. Recording techniques and mic placement
5. Room acoustics and monitoring
6. Editing, mixing basics and file formats

How long does it take to learn Audio Engineering?

With a few hours a week, most beginners understand signal flow, microphones and gain staging and can make clean home recordings within 3 to 6 months. Professional-level recording and mixing skills usually take several years of hands-on work with different sources and rooms.

What you need before you start

Access to a computer with a DAW, headphones, and ideally an audio interface and microphone. Basic music knowledge helps but is not required.

Common mistakes to avoid

Recording too hot and clipping the converter. Leave plenty of headroom, since digital clipping cannot be undone.
Ignoring the room and blaming the microphone. Small changes in placement and treatment often matter more than gear.
Mixing on uncalibrated, loud monitors. Listen at moderate levels and check mixes on several systems.

Audio Engineering questions, answered

What is the difference between dynamic and condenser microphones?

Dynamic microphones are rugged and handle loud sources well. Condenser microphones are more sensitive, capture more detail and usually need phantom power, making them common for vocals and acoustic instruments in studios.

Do I need expensive gear to learn audio engineering?

No. An entry-level interface, one good microphone and headphones are enough to learn signal flow, gain staging and mic placement. Skill and listening matter more than gear at first.
