    I went to school for audio engineering. This 12 minute video discussed phase and Time aligning more than any of my classes in college.
  • @suitandtieguy
    the casual mention of "I had this dual delay adjustable in microseconds made for me by Eventide" is the most massive flex i've ever seen in a recording techniques video.
  • @ivan_emege
    Rest in Peace, Steve Albini, excellent producer and engineer. I’ve enjoyed your informative tech videos so much.
  • @jiro7997
    The second part of the video where Steve was adjusting the distance between the two mics should have gone on for like an hour longer with incrementally worse and worse results until he finally went completely insane because that's what happens when I try to do it.
  • @chanc3hurley
    Steve is one of the few people that I can absorb information from instantly. Like i`m actually being taught from an actual professor instead of some armchair expert with an obvious lack of experience. I could never afford an audio engineering education, so these videos are worth their weight in gold to some of us. Even the basics such as this. You`re doing the lords work.

    Is it just me or is Steve Albini truly one of the most fascinating and down-to-earth nerds ever?!?

    I met Steve in Manchester at a Big Black/Head Of David gig at the Archway Club (right across from the Hacienda, kids!) in '86. He was standing in the crowd waiting for Head Of David to come on, so I told him we'd travelled down from Glasgow just for this gig, and would it be okay if I recorded his group on the Sony Professional Walkman I just happened to have with me. Not only did he say it was fine with him, he introduced Head Of David on my little microphone, just as they were coming on stage! Then during Big Black's set he told the crowd about us hitchhiking from Scotland just for them!! How cool is that!

    I fuckin died at "It's a wonder it works at all!" This was great

    "He has a fucked-up knee, so he can't leave." I'm dying of laughter right now! That was hilarious and the delivery was amazing!!

    5/10/24: Goodbye Sir. I have watched and learned so very much from you and your team! Condolences to everyone who is feeling your loss today and going forward. Namaste

    This is why the internet isn’t all bad.
  • @HiFi-Yeah
    Steve really knew what he was doing, and with such massive attention to detail in getting the fundamentals right (instrument, room, mics, phase).
  • 02:25 For anyone interested in his explanation. Great, genius man! "It has to make its way through a pretty elaborate system before it finally gets to this microphone. It has to go through the input circuitry of this amplifier, which has time constant, and the preamplifier has to get the signal to the power amplifier section, which it then has to modulate the power supply through the out port, output transformer, which then needs to couple the primary and secondary windings to the output cable, which goes to the loudspeaker, which then gets it voice coil energized, then the voice coil drives the speaker cone inside its magnetic gap and the compliance of the cone needs to move the air that's in front of it, that air pressurizes and the pressure wave travels through the physical distance between the loudspeaker and the microphone, than the microphone diaphragm needs to move and make its way through another transformer and down the cable, that it has some capacitance, then into the microphone preamplifier...It's a wonder it works at all" ps: i managed to slow it down using reaper, so its pretty accurate.
  • @veerchasm1
    This guy is a legend and his ability to breakdown sound physics is unmatched
  • @johnpeters9777
    Finally, a true Engineer demonstrates on an oscilloscope reality. Everyone else is just guessing ultimately saying "my ears are as sensitive as an oscilloscope". No wonder there's so many bad mixes.
  • @SupaFUZZZZZZ
    I never knew if Steve studied engineering or if this was all self taught. Believe he studied Journalism at Northwestern University. He's obviously a genius. Can anyone let me know if he had formal education on engineering? RIP Brother. You are a legend and will never be forgotten.
  • You may not take these YT vids that seriously, but you offer proper audio engineering tips, insight and information, and that's such a breath of fresh air, compared to all those clickbait, subs-gathering channels that just push audio gear and rehash audio tricks. Brilliant - thanks
  • "America's most top liked guy, He's got a FUCKED UP KNEE so he can't leave...." Aside from being an extremely educational video...it made me fall off my chair and laugh my ass off. BRAVO!!!!

    What a lot of folks don't get is this is very important stuff for free.Respect.
