Frequency Domain and EQ Basics

You see frequency domain all the time when you use audio equalizers, but how clear are you on what that is, exactly? Learn how to master any EQ/spectral analysis tool by watching this video on exactly what the frequency is, why it’s important in the music/audio field, and how—if you do any mixing whatsoever—you come across it all the time.

Once you’ve got this part down, you may be interested in learning about the actual method used to get a sound representation from the time domain to the frequency domain. If so, check out this link for more: http://zone.ni.com/devzone/cda/ph/p/i….

Audio Interconnections: XLR, TRS and More

*Singing* The quarter inch tip is connected to the…positive! The sleeve is connected to the…ground wire!

Okay, we at the Science of Music are nerdy but we’re not quite that nerdy, we swear. But understanding cables and interconnections will help every musician who has to deal with gear. From XLR to RCA to the immortal midi cable (which has two unused pins…seriously, check it out), having an understanding of gear, mic, line, and insert cables will make your life infinitely easier.

Introduction to Transduction

Simply put, transduction is the process of converting one type of energy to another. For audio-specific purposes, if you’ve ever used a microphone or a speaker to record or amplify a sound, you’ve seen transduction in action.

A microphone works as a transducer by changing acoustic waves to electrical waves.  And a loudspeaker is also a transducer, even though it does the opposite: by changing electrical waves to acoustic waves.
