This channel is a goldmine. I come at this from the perspective of someone interested in the science of audio reproduction rather than creation but everything either directly applies or is useful to know. There are few other resources that have compiled so much factual information covering such a wide range of topics. Invaluable for anyone interested in any area to do with record(ed/ing) audio, apart from just listening.

[@AudioUniversity]

Thanks for your comment, GrB! I'm glad you're enjoying the channel!

[@isaacjohnklein]

This channel and Dan Worrall's channel are hands down the most educational channels on KZbin for audio engineering and it isn't even remotely close.

[@bealotcoolerifyoudid7217]

Man I cant stress enough how helpful you channel is. Thank you for doing this.

[@AudioUniversity]

Happy to help! Thanks!

[@marceloarenas5486]

Thanks again!!! Excellent explanation videos!!

[@catoleg]

Short, clear and straight to the point. Thank you so much sir

[@dafo115]

Nice video. One thing to add is that with headphones, the ideal response isn’t typically “flat” in the same way that speakers or microphones are. Since the headphones are projecting sound directly into your ears, to sound more natural they will be tuned to emulate a HRTF, e.g. using the Harman curve. But yes, taking this into account, some headphones are more “flat” than others by minimising any additional coloration of the sound.

Thanks, Thomas! Glad you enjoyed this one.

[@RMVibes]

always bringing awesome content 👏👏👏 i am looking for some way to change the EQ from my cheap microphone to use it as a Measurement Microphone to EQ my Room.

Thank you

Gear video once again boss

[@bayridge99]

Excellent video thanks, but I wish the mic was not so prominent! Some KZbinrs get so close they are continually ‘ popping’ the plosives!

[@AudioUniversity]

Thanks, Bay Ridge!

[@Rene_Christensen]

The frequency response is the combination of magnitude response, which you show here, and phase response.

[@zimouspero]

This going to help me , when i decide to by a Speakers and mics

[@AudioUniversity]

Glad to help!

I have been working with Q-SYS by QSC for the last 4 1/2 years and now work for Q-SYS as of this year. It is not only a vary powerful DSP and Control platform but a wonderful tool tool learn about many audio principals as your imagination is the limit to what you can do with it. I'd be interested in what you use it for in your setting.

[@AudioUniversity]

I have a Core 110f from an AV installation I worked on. I agree though - you’re only limited by your imagination!

[@kennylux]

2:35 I still don't quite understand, what's the point of having boosts/cuts in the frequency response? That's basically EQ, and you can revert/change EQ settings, but the frequency response is permanent. My point is, flatter still seems better in any scenario I also have another question. You said everything has a frequency response, so does my PC or my audio interface (say focusrite 2i2) have one as well?

[@MrMuppetbaby]

Love the channel. I have a lot to learn. Question for you: Can you recommend a room correction solution for a budget home studio owner with analog outputs that is better than the MiniDSP-HD? I hear that it is not great at full range and is more suited to bass crossover and sub correction. Companion question: The Adam Audio A7V speaker has built in DSP for room correction in conjunction with Sonarworks. What do you think? Thanks! Tod in Las Vegas :)

Another excellent video. With respect to this subject, I presume cables have a role as well. There are myriad advertisements about one cable being superior to others. What is your scientific take on cables?

[@AudioUniversity]

While cables may have a subtle effect on sound, the effect on frequency response is infinitesimally small. I'd focus on acoustic treatment, source quality, amplifier, and speaker before even thinking about upgrading cables. In my opinion, the main benefits of good cabling are longevity, reliability, and noise isolation. You can almost always get a more significant SOUND QUALITY improvement with acoustic treatment rather than premium cables.

[@seattlevegas66]

@@AudioUniversity Thanks! My cables are probably fine. They are old, but in good shape. Since I rarely run longer than 20 feet or so, noise isolation does not seem to be of concern. I do need to deal with the studio acoustics though. Appreciate the education!

[@OnyinyechukwuBoma]

Hello, I am planning to do a frequency response test for a room I plan to setup a studio in to see the EQ curve of the speakers in the room. What do I take note of and what steps do I take to ensure the best possible result.

[@AudioUniversity]

Check out this video: kzbin.info/www/bejne/qpWahphua7ihnMU

[@santiago3641]

Great video, but still I'm confused on using plugins that do this. If I'm using a plugin that modifies the curve for you (Sonarworks ID Reference) and at the same time an ambience plugin for room perception while mixing on headphones (Realphones), should I turn off the "EQ" curve on Realphones? I love both plugins but highly confused when more than one is on the master channel

[@AudioUniversity]

That's an interesting question! I guess they could coexist with a positive result, in theory. They would just need to be configured together. I'm not sure if it's possible, but you could theoretically configure one, then leave that tool engaged while configuring the next tool. If they are both attempting to make the dry signal sound a certain way, they won't have that same effect when used in series with one another. Hope that helps. Thanks for watching!

[@santiago3641]

@@AudioUniversity It does. Thanks for the reply

[@kanotki]

I have a question what do you call a person that studies audio Is it an audio engineer or something else I need it for college Sorry for bad English

[@sankarn.s5645]

Why some mic frequency response is 20 to 20khz....and others 80 to 15 khz??

[@AudioUniversity]

Some microphones are designed to capture a specific source. Some sources don't produce frequencies across the spectrum.

[@sankarn.s5645]

Is mic with frequency response 80 to 15 khz sufficient for conferencing

[@AudioUniversity]

Yes. The human voice typically only goes down to about 80 Hz anyway.

[@i-m-alien]

high---mid----low-----so how a single eq knows that the 3 frequencies are passing through it........means a road never knows how large or small vehical is passing through it

Yes you are! Thanks for watching!

[@JeremiahHartmanPhotography]

Wait..we have to worry about frequency response when doing tracking, mixing and mastering??? But I thought If i just wear Beats headphones like all the famous producers my mixes will win grammy's too?? LMAO!!!
