Applied DSP No. 5: Quantization

Applied Digital Signal Processing at Drexel University: In this video, we examine quantization and how it affects sound quality and signal processing.

This video sat around partially done, leaving a conspicuous gap in the Applied Digital Signal Processing series. Sincere apologies to those who have been waiting and waiting… I'm teaching the course again this Fall (September 2022), so I *really* will be posting more in this series in the coming weeks. Now would be a great time to subscribe to my channel, @youngmoo-kim, for updates. Please leave feedback in the comments and let me know if there are DSP topics you'd like to see in future videos!

The quantization example is from an unreleased recording of the "Gloria" from Bach's Mass in B-minor, BWV 232.

Bloody hell what a brilliant video. Can't wait to watch the others. So clearly explained. Smashed it! Thanks!

This series is gold, I haven't found any other DSP resource that's as comprehensive and practically applicable yet intuitive as these videos. I skimmed through Steven Smith's DSP book and watched this series and I was up and running with audio DSP from scratch in C++ within a week.

Thank you for still creating the missing episode. The DSP videos helped me a lot in my studies at the beginning of the year. I continue to look forward to new and educational videos from you. 🙂

I wish this video would have existed 20 years ago! Would have saved me a lot of time and research. Congrats on such a concise coverage, in such an elegantly simple way plus some interesting history I didn't know about!

[StephanBuchin]

Wow! We have been waiting a long time for this one 😎 Thx.

Thank you for the videos! They are amazing. Extremely underrated channel, but I am sure it will gain more attention soon. :) Thank you!!

keep it up! we need more of this content in EE!

Mr kim. Thank you so much for sharing your knowledge on signal processing! Your videos have been incredibly helpful and insightful, and I've learned a lot from them. Please keep the great content coming; it's really appreciated by everyone looking to deepen their understanding in this field! Greetings from germany! 🙏📚

YOUNGMOO! I just binged all of these. So amazing. I got a little bogged down by some of the Math, but that just gives me something else to learn. Thank you!

[eduardojreis]

Wow, finally a great explanation on the whole dB unit and measure.

[zandijian]

this is amazingly informative, thank you for making these videos!!

Hi Youngmoo. Great video as always. Thanks! Do you have any references for fixed point quantization of IIR filters, particularly dealing with accumulation of errors during recurrence

[taurus_]

Great explanation! what software did you use to edit this video?

[ВладимирКузнецов-рн]

Hi! Great video and visualization! Could you tell me the name of the program that was used to create the animation? I really into use this tool in my education as well)

Youngmoo, for the audience, will you do your Bob and Doug McKenzie "Take off to the Great White North?" You know the "Cooo, loo, coo, coo, coo, coo, coo, coooo! Cooo, loo, coo, coo, coo, coo, coo, coooo!" : )

This channel is massively underrated. Have you thought about participating in SoME2? It would boost your channel.
