Course Overview

In this introductory course, students learn about the physics of sound and the history of recording technologies. They learn about the four stages of professional music recording projects: recording, editing, mixing, and mastering. Using Audacity, an open-source recording and mixing program, they practice the techniques used by sound engineers to produce multitrack recordings. Through a series of engaging hands-on projects, they learn the fundamental concepts of audio engineering.

Section 1: Understanding Sound

Students learn about sound sources; the parts of a speaker; the parts of an audio waveform; and the difference between volume and loudness. They learn to measure amplitude; generate sine, square, and sawtooth wave tone waveforms; duplicate audio tracks; identify different phase angles; and use the Time Shift Tool. They learn about frequency, pitch, and octaves; how to generate tones at specific frequencies and octaves; and how to loop, mute, and solo audio. They learn simple and complex waveforms; harmonics, fundamental tones, and partials; and how to remove noise from an audio file. They learn about health and safety for audio engineers; sound thresholds; hearing protective gear; ergonomics; and repetitive strain injury.

  • Make Waveforms
  • Manipulate Waves
  • Frequency
  • Clean Up Audio
  • Health and Safety

Section 2: Recording Audio

Students learn about analog recording technology; mechanical audio devices; overdubbing and multitrack recording; and the disadvantages of analog audio recording. They learn about digital recording technology; digital audio hardware; acoustics; and recording studio equipment. They learn how to address echoes, reverb, leakage, standing waves, noise floor, and frequency balance.

  • Echoes
  • Reverb
  • More Acoustical Problems

Section 3: Audio Software Tools

Students learn about the features of DAW software and DAW-specific hardware; the features and advantages of Audacity; MIDI and its history; MIDI cables and jacks; and the use of MIDI controllers. They learn about looping software and when to use it; syncing; and how to change the tempo, pitch, and speed of an audio file. They learn about audio file formats; file compression and audio data loss; constant and variable bit rates; and metadata.

  • DAW Software
  • Other Audio Tools
  • Multitrack Music Project
  • Audio File Formats
  • Encode Audio

Section 4: Mics and Mixing

Students learn about microphones, transducers, connectors, active and passive mics, and phantom power. They learn about frequency and transient response, the proximity effect, output characteristics, mono and stereo sound, and techniques for placing mics for instruments. They learn about intellectual property, copyright, digital rights management, fair use, public domain, and Creative Commons licenses. They learn to mix samples, remove unwanted audio tracks, repeat samples, change the gain, and pan an audio track. They learn to split a stereo track into two mono tracks, combine two mono tracks into a stereo track, and use the Envelope Tool to modify an audio track's envelope.

  • Microphone Hardware
  • Microphone Specifications
  • Microphone Placement
  • Using Other People's Music
  • Mix Samples
  • Finish Mixing Samples

Section 5: Mastering Sound

Students learn about mastering; audio signal processing; equalization; and positive and negative decibels. They learn to equalize audio with the Equalize Tool; draw curves; make and save a curve preset; read the level meter; and find the peaks in an audio track. They learn to compress and normalize audio; fade and crossfade sound; add a Phaser Effect; and add wahwah to audio.

  • Mastering and EQ
  • Continue Using EQ
  • Compress Audio
  • Normalize and Fade
  • Phaser and Wahwah Effects
