Wow.. I would never have thought of this technique! Great work Dr. Mix!

[richdiggens]

Really liked this kind of video, it’s probably a little advanced for me at this stage as I’m still writing music on acoustic instruments but when I’m soon ready to start recording myself it will be good to have this video for reference. Thanks so much x

Awesome work dr MIX....love from INDIA

[ronnyb]

thanx for showing me other usages of noise canceling techniques, didnt knew that

[StefanChamberland]

You just blew my mind Doctor Mix, thank you for taking the time to make this video. I will be using the null test from here on out.

Using Null testing for the purpose of equalizing? WHAT 🤯
I never thought of doing this. That's a life changer! D:

Thanks for sharing the technique of null testing.

I alsie use it to check if different masterings are used for WAVs of the same song on different CDs. If I hear nothing, then it's the same exact mastering/file on different discs.

Dude this is gonna save me so much time checking all of my old tracks thanks a lot

[NielsHeusinkveld]

Perhaps this was already commented.. If not, MP3 files seem to not start at exactly the same time as the original WAV files, so the difference is greater when you overlay them as I believe there is a tiny bit of delay before the MP3 actually starts..

Hey Doc, thanks for all the great videos -- it has been inspiring to watch your channel!

[RogerioValgode]

Great tip! Love the way you make it simple 👍

[unstopology]

My mind is still blown. I'm going to need a while to process the last part. Great info, though!

[FrequencyModulator]

Amazing video! Very useful! Gonna be playing with the null test for a while :)

[eucabusas]

Tnx Doctor Mix! This'll help me save time as what I usually do is playback the tracks one by one and check for dropouts.

[garyspianocovers]

Your channel is simply awesome, well presented, keep it up.

[francescogoldoni]

Very cool and totally useful video. Hope more of these are coming up! Good job

[Lol_Pig]

You just solved some issues I've been having. Thanks!

Great technique. I saw it used in a demonstration about loudness and compression. And I learned something else. That song "the Groove" sounded to me as being from Shakatak, a band I always liked. So searching for it I didn't find it, but instead found the original from 1980 from Rodney Franklin. I found that Shakatak`s first album "driving hard" was released one year later, in 1981. I felt kinda dumb. But I also found the great version by Sunlightsquare. Did I understand correctly that you had a part in that? Cheers from the Netherlands!

This is a great channel. Have used Sonar Home Studio with a m-audio fasttrack ultra, no latency. I find all DAWS to be complicated, so I downloaded Bandlab (essentially its supposed to be the Platinum version of Sonar for free). Terrible latency. I can't find the driver settings that I used on Sonar. Bandlab has latency test (hold a mic to the speaker & the software determines & supposedly corrects the latency next time you record) but I'm playing a guitar & getting latency! Its a pain,
