Sir, i would like to know which textbook you have referred to in learning this topis, because i haven't come across any with such a detailed and intuitive explanation
brother please suggest books to self learn sound engineering and relevant subjects that are necessary to learn first. It can be a highly detailed set of books because I won't have much problem with the mathematics, I have a degree in math. please do brother. thank you!!!!
Hello, I didn't quite understand the part of leaving a buffer between required frequency and nyquist frequency: I understand that when converting digital signal back to analog signal, the low pass filter does not perfectly remove all undesired high frequency component, so we have a small portion of signal goes beyond the desired frequency. Whether setting the a buffer or not, this small portion of high frequency signal will always exist (Like for the buffer case you show at 18:56, there is a chunk in the buffer area). I can see that this region is distanced from the nyquist frequency. I don't understand why is it better, because in both scenario (desired signal frequency near 1/2 of sample rate or much lower than sample rate), we both have an undesired chunk.
This was a great series. Thanks. I’m currently watching every one of your videos. I’m 48 and learning just a bit, but your lesson on PCM finally made me understand.
The visualization of these and the clear explanations and examples, is highest quality. I’m just a mere producer but I could grasp the concepts. Elite content 👌🏾
@@SANJANADHARMENDRATIWARI haha! Thanks for the compliments regarding the voice. There is actually a filter there, an FIR filter to filter out low frequency background noise (of the laptop fan), but that's just how my voice sounds.
I'm begging you. Please do more of this content. It really helps with my understanding to visualize things. If possible I wanted to know more about digital signal processing
@@herevancelightena9770 ahh, thanks, I really want to be faster than the pace at which I'm releasing these videos. But it's difficult with work and my other hobbies. I hope to get back to form with regular cadence of videos, soon.
It's staggering how good these videos are. From presentation, to explanation, these are flawless. I wish I had bumped into them sooner, but I'm going to watch them all now.
This guy needs to find a new career. EE and digital signal processing is not something he understands.. just dumb babble talk. Anyone is better spending their time reading Oppenheimer's book.
Hey these videos are fantastic! I’m a software engineer in a different domain and I’m getting into some audio processing for doing sound reactive lights and such. I had no idea what I was doing but learning the concepts of signals and sound waves and these videos help a ton, thanks dude!
Seriously some BBC level of educational visualization and voiceover. Some minutes later: The level of clarity in these presentations are on such a high level. This requires so much skill AND actually understanding what other people struggle to understand. My biggest frustration as a weaker student was that most of the smarter students were unable to explain what they just did or why they did it during a mathematical solution. Bridging your understanding and communicating with the clarity in this series is some impressive work. Anybody trying to write an ad, web page or any message or presentation restricted in size/time will eventually run into how what to leave out, what to keep and how does that affect the end message? Very few actually master the art of losing seemingly nothing due to the careful buildup and awareness of the listener's level of understanding. I am mightily impressed.
thank you so much, you are trully amazing, you've helped me so much in undrestanding this subject better than any teacher ever. thank you for these amazing videos
Akash! This is amazing! Phenomenal job on simplifying these complex concepts and making them easier to understand. I am an engineer and still find audio engineering quite confusing until I watched your video! Now, I find these terminologies a lot easier to understand. Thanks!
Just brilliant! I will have to dig into the mathatical aspects, but your videos are a great help to relate the more complex concepts to real world audio perception
@akash murthy. can you please kindly explain why the phase response for Nyquist pattern is 90 degree? From my understanding, after going through the filters, everything gets cancelled out ... Thank you
Good question. If you look at 10:30 I talk about how a 1 sample delay causes 90deg phase shift in the 1/2 Nyquist input signal, but the output signal as a result of the combination of original input and 90deg phase shifted input is 45deg phase shifted. It's the same case here. The phase shift represented in the graph is the phase shift of the "output signal" of the filter, not the phase shift introduced just by the delay element.
