Learn Audio DSP 2: Basic waveforms and sampling

[@connylandstedt]

wavwrite is obsolete in Octave 5.1.0 and replaced by audiowrite audiowrite('square.wav', tone, fs); Love the tutorial, real easy to follow.

my goodness im slow

[@ankitanand3115]

You guys are the reason for me scrolling through the comment section. Saved a heck lot of time. Thank you

[@themarktron]

why a language have to f*** change commands, they coul preserve it change IT´S NOT STANDARD

[@ankitanand3115]

I feel blessed that I got this video. Only 11,000 views that means I have chosen a path which is not travelled by a lot of people. Thanks for these contents

[@happilyconfuseddog8951]

these are great Dan, please keep this up I'm learning a lot! Really looking forward to the next one Are there any other resources that you would recommend for getting into audio plugin development?

[@DanPrince]

I am glad that you enjoy them so far! I don't get a lot of fans that are dogs. One of my favorite resources is Miller Puckette's Theory And Technique of Electronic Music. There are lots of descriptive examples in Pure Data, and he gives a pretty good theoretical background too. Here's a link to the book in a few different formats: msp.ucsd.edu/techniques.htm Digital Audio Effects by Zolzer is good too. It's a little more theoretical, but it has examples you can run in Octave.

[@DanPrince]

Hey confused dog, just wanted to let you know that I have a new video up! Here's the link: kzbin.info/www/bejne/qou2h56go6-nY6M

[@4FlexxMusic]

You're a fan of Radiohead, Flying Lotus and DSP, let alone also digging that Red Bull documentary...we should be friends. In all seriousness please keep these up - I wasn't expecting this much quality/clarity from a relatively small channel. Love your content and wish you the best with it.

[@DanPrince]

Hey 4Flexx, since you liked my videos before, I just wanted to let you know that I have a new one up! Here's the link: kzbin.info/www/bejne/qou2h56go6-nY6M

[@forresterickson6225]

Very helpful tutorial. Using Octave 6.4 I can not get both the command window and the editor open at the same time like he did. Something must drag I guess that I do not see. Anyone?

[@forhadahmed4643]

such a cool tech dude.....you are..... hope you a great youtube experience....

[@rasmusmerten9840]

My octave is just opening the first of the two plots, but i used the exact code :/

[@dan_dorjay]

Do you have any time to make some more of these videos? Really clear explanation. Thanks for taking the time to do this!

[@DanPrince]

Hi Dan, I'm getting back in the swing of making these videos. Here's my newest one I just uploaded: kzbin.info/www/bejne/qou2h56go6-nY6M

[@dan_dorjay]

Dan Prince great news, thanks very much! :)

[@OttosTheName]

Only been watching for a bit, but love the series already. Also thanks for referencing that digging the carts series, sounds super interesting. (And love the little Amen Break you put in there :P)

[@ani2595]

Hi Dan I am currently working on a project that involves sampling audio files using Octave. I am currently taking a few songs out of my music library and was making a mix out of it. I am currenlty stuck on how to make a fade in and fade out effect between songs. Would you know how to do this to an existing audio file? Thanks

[@bubuDev]

Hello Dan !! Thank you so much for this lectures !! These are really useful !! Would you do a video on how to get a band limited square wave ( 20:56 ) ? Watching your Additive Synthesis lecture I see that the Square wave synthesized there "has ears" , but probably that's not the band limiting solution you talk about here =) thank you =)

[@ngkktht774]

I find it misleading that you say that we have no idea about values between the samples. I get it that you wanted people NOT to imagine that connecting the points with lines is the correct way (even if even that gives you some idea), but it would be worth mentioning, that even if we don't know the values in between, we can compute their exact values if we need to (by multiplying each sample by sinc function and summing all the results).

[@ngkktht774]

You have two samples in row with value one in your triangle signal. Is that correct triangle signal? Shouldn't the triangle wave have just one sample at the tip (and dip)?

[@pipelineaudio]

a*tone doesnt seem to be changing the amplitude when using audiowrite instead of wavwrite, is there a trick for that?

[@amanranjanverma]

your explanations are pretty owesome. But how did you manage to bring command and editor window in a single window. Plz help.

[@Soundwaves4ever]

Why is it when I'm trying to explain audio waves people look at me like a deer in the head lights

[@onpatrolforthejuice]

youre a great teacher

[@ankitanand2448]

At 11.38 when you plotted the values?what was chosen as x axis?

[@DanPrince]

The x axis there is just the index into the array. The first value gets plotted at 1, the second value at 2, and so forth. Nothing fancy!

[@ankitanand2448]

Thankq

[@yoanmolia8652]

Incroyable, vraiment un grand merci from Paris

[@lxuaes6915]

What are your thoughts on pure data?

[@DanPrince]

I've tried it a few different times. I think the fact that it runs in real time by default with little effort is a huge advantage. In general though I have a hard time thinking the way PD wants you to, and I often wished I could write a for loop or something that's easy in traditional programming. I also thought it was hard to stay organized with bigger projects, the visual organization seems to make more sense with smaller projects.

[@Oversat_]

I hope you will continue this series!

[@DanPrince]

Medvi, glad you liked this one! I just wanted to let you know that I uploaded a new video! Check it out: kzbin.info/www/bejne/qou2h56go6-nY6M

[@fano72]

Gnu octave?! fascinating!

[@AndrewMooreVideos]

Awesome stuff. Thanks so much. As a musician learning DSP, it's so helpful to have things practically explained and demonstrated like this. Looking forward to seeing the next ones!

[@DanPrince]

Hey Andrew, I finally made another video! Here's the next one in the series: kzbin.info/www/bejne/qou2h56go6-nY6M

[@DalasYoo]

such a good tutorial to begin the interest on audio processing. Thanks for your good work!

[@cyanozoid2706]

Great video, sir! Really appreciate the work that went into this.

[@hyuuj]

Both of these videos were great, and I'd love to see more! They're now my go to when colleagues ask about getting into DSP. Awesome work! Thanks!

[@DanPrince]

Sup Charlie, I finally got around to making another! Here's the link to part 3, and expect to see a new one within a month or so! kzbin.info/www/bejne/qou2h56go6-nY6M

[@beachforestmountain4269]

Thanks - that was easy to understand.

[@popedoge7656]

these videos are great why didnt you make more

[@DanPrince]

I’ve got another in the works right now actually! Subscribe and check back in a week or so! 😁

[@DanPrince]

Hi Pop, just uploaded my next video! Check it out: kzbin.info/www/bejne/qou2h56go6-nY6M

[@flecksrandomstuff4593]

Next video? :)

[@katanaswordfish]

Great videos Dan!

[@mikael5743]

Awesome, when will the next video be released? Keep up that good work, cheers

[@DanPrince]

The next video will be released yesterday! Here's the link: kzbin.info/www/bejne/qou2h56go6-nY6M

[@fre3azy397]

definitely one of the clearer tutors around really hope you get round to more videos sometime

[@DanPrince]

Hey Fre3azy, I found some more time! Here's my newest video: kzbin.info/www/bejne/qou2h56go6-nY6M

[@maxthurn3879]

Dan youre the man! Thanks for these great videos :)

[@DanPrince]

Thanks for watching Max!

[@alfonsosantimone]

great stuff! any part 3 coming soon? thanks!

[@DanPrince]

Part 3 coming yesterday! Here's the link: kzbin.info/www/bejne/qou2h56go6-nY6M

[@floggerN]

T is a little bit confusing as a variable :) Thank you for your video.

[@DanPrince]

Nicola Pianta thanks for the feedback. Capital T is used pretty commonly in dsp literature to indicate period, but of course these videos are meant for people who don’t already know that stuff! I’ll be careful to use more descriptive variables in the future. Was everything else pretty clear?

[@floggerN]

Yes, your video is very intuitive and funny at the same time. I really hope to watch many others! It's been a long time away from DSP. Thank you!

[@frechjo]

Naw, man. Don't trash the formulas with long names, the comment should be enough. What do you prefer? This: A = πr² or this: area-of-circle = ratio-of-circumference-to-diameter * radio * radio

[@DanPrince]

If I don't have the context of already knowing about geometry and the understanding of what A, π, and r stand for, I would actually prefer the later! I'm trying to make content for people who don't have a background in signal processing, so I would prefer to use more verbose descriptions.

[@tdzproducoes4276]

very much appreciated. thx man

[@tdzproducoes4276]

eagerly waiting for part 3 !

[@DanPrince]

Hey TDZ, here's part 3! kzbin.info/www/bejne/qou2h56go6-nY6M
