Transient and Frequency Response
By Lorenzo Canadilla and Jackson Beveridge
Frequency Response
• The way a microphone responds to certain frequencies. It is the tendency of all mics to exaggerate certain frequencies and reduce others.

Frequency Response Curve
• This is the measure of the mic’s output over the audible frequency range
• Gives insight into how a mic will react at certain frequencies
Microphone preference
• Condenser mics usually have a flatter frequency response curve for they are more concerned with all the little sounds in a recording.
Types of Microphones
• Certain mics are created to emphasize the high, middle and low range and some respond equally to all.
• Tailored FR mics are those that favor a certain range of frequencies. For example their output in decibels could be higher for a 200 hertz frequency than for a 500 hertz frequency.
• Flat FR mics are those that respond equally to all frequencies.
Transient Response
• The measure of how quickly a microphone’s diaphragm can respond to changes in waveform
• The change in wave form refers to the transient, which you may remember is the high amplitude short duration sound at the beginning of a wave form.
• This can lead to a range of differences in the resulting sound between microphones, specifically when it comes to percussive instruments.
Microphones That Directly Relate to Transient Response
• Dynamic mics have very large diaphrams and heavy cores which make it slow when reacting to waveform. This gives it a rugged, lagging sound.
• Ribbon mics on the other hand have a lighter and smaller diaphragm that allows for faster reaction to waveform. They would be more ideal to record percussion.
Dynamic Vs. Ribbon
Why do we care?
• To know what type of mics to record certain aspects of a musical composition with.
• To increase the control of the waves we have to work with
• Also to have basic understanding of how his equipment works
