Why Spectral Frequency Analysis Is Important In Testing Audio Chains

Kind of randomly got here, but this was interesting.

Good one Jesse! This is a use-case for spectral analysis that can benefit anyone building or upgrading their system. Now I want to do some testing on mine!
A small correction in terminology, what was referred to as echos on the sine waves are actually overtones and undertones or harmonic ghosts appearing at exact upper and lower multiples of the root frequency. These are attributable to system and headphone amplifier nonlinearities, and the quality of the A>D & D>A converters.

thanks for the lesson, will be looking for this feature in other apps/daws. also, I respect wearing a (bow)tie for recording

That's what I miss the most in Adobe Audition; the spectral frequency display. I used it once to erase a phone ring tone during an important dialog scene. Audition lets you see the tone and then erase them with simple tools. Those tones were out of the speaker's voice range so noting was lost. I hope Black Magic Design can put that feature into Fairlight some day.
