I would buy a coffee for someone who does not use white text on a white background, with only a thin outline of the letters for contrast.. No coffee for you. Garbage sound quality too.
I’d recommend some sound treatment panels for your walls. It’ll improve your audio quality immensely. Good content, just hard to understand with the audio recording issue.
I'm sorry, but I have a hard time not focusing on the sheer amount of real cool and heavy titles in your bookshelf. Oh and forgot this: Thanks for the time and effort!!
Thanks for the detailed explanation. The only thing that I'd love to be added is some sound examples of comparing unfiltered and filtered sine sweeps. Suppose that the left channel of your recording would contain an exponential sine sweep of 10 seconds in length while the right channel would contain the same sine sweep filtered with the allpass filter that you're talking about (assuming both sine sweeps would be aligned in time with single-sample accuracy). Or, let's say that when you talk about the allpass filter being actually a convolution of some two other filters (I think you said something like this there), again, I'd love to hear a sine sweep being run through each of them (on one channel, while the other channel would contain the unprocessed sweep). This would help people like me who are used to mentally converting (sometimes pretty quickly) sound to maths or maths to sound. I do these conversions almost on a daily basis as I'm interested in things like tunings and microtonality and non-standard scales and new harmonic systems and all that stuff, so I switch from ratios to cents or from cents to ratios pretty often.
Thank you man, I'm learning Waves Inphase plugin and i was not understanding the All pass filters. Through this video i did not understand completely, but now i have some kind of little idea of that. It's not your fault. I would like to give suggestion too, consider using some more easy graphics please, the equation part was complicating for me. By the way you know what is right for the video. Thank one more time.
Thanks for such a comprehensive explanation and directions for further study! I am learning Bitwig's Grid, and allpasses are a big part of making reverbs, apparently, so I wanted to make sure I understand what they do!
Good tutorial! I came across a different formula for the first order allpass: w = abs(fb)*2Pi/fs ; a1 = (sin(w)-1) / cos(w) ; ... that only seems for first order though, but maybe it’s just a different way to the same place
your video is amazing. absolutely essential to learn for DSP, . could you reproduce this video with a lavalier or directional mic. you are giving out such good info that it would be bad that people would not listen or stay on the video because of bad audio. anyway. thank you so much for this.
Haha, I have read some of them but not all :) These books are the property of the Aalto Acoustics Lab and I happen to record the videos in their mini-library. There's a funny story behind these books though; while I was studying, I was puttig together a list of books in audio and programming I would like to own or read. When I arrived at the Acoustics Lab, I saw that all those books were already there in that one room... It was like visiting Honeydukes from Harry Potter :)
If all this math is too much for me, where do you suggest I go? I know basic decreete math for computer science, but this seems just a step more advanced.
holy shit. I used to be exceptionally good at math & physics 20 years ago in high school, but this just makes me feel DUMB now. 😹 off to look for the "for dummies" version to figure out exactly what the all-pass filter in Volcano 3 does...
@@WolfSoundAudio lol. No worries. I’m sure this is is fantastic for a mathematical/physics approach to it, though was just looking for something basic and kinda dumbed down more pertaining to the practical application of how it sounds. Mighta found something else though sorta forgot already, just resorting to playing/experimenting and learning that way - which is often the best route anyways 🙂🥂
