DAWs and other modern music technology offers us a wealth of different ways to do things, but if we are being honest, how many people skip the fundamentals of digital audio and jump straight into making beats or tweaking synths? There's nothing wrong with having fun, but an understanding of how sound actually works can be an invaluable help to you as you progress through your musical career and journey. In this 1-minute video from the course AudioPedia 101: Sound Waves And Hearing, Joe Albano gets to the heart of one of the fundamentals of audio - the waveform graph.
Waveform graphs essentially plot amplitude against time on the X and Y axes. The vertical axis indicates the strength of the vibration the sound is causing to the air, also known as the amplitude. The horizontal axis is time - the speed at which the variations are occurring. The shape of the wave shows the pattern of the vibration. Finally the wave shape corresponds to the timbre of the sound. This is just one of the core fundamentals of audio covered in the full course, so be sure to check it out to make sure your sound skills are up to scratch!
