Analyzing and synthesizing spring reverb
I've been interested in spring reverb lately and it's unique "drippy" sound. In this video I reverse engineer a spring reverb impulse response and take a stab at synthesizing one like it from scratch.

Programming basic FIR delay effects and convolution
Просмотров 6 тыс.5 лет назад
In my first Python DSP video (!!!), I make a basic Finite Impulse Response (FIR) audio delay effect and use it to introduce convolution. We can use this to create echoey effects, and practice these concepts since they are core to a lot of more complex DSP ideas.

Learn Audio DSP 5: Fourier series and additive synthesis
Просмотров 7 тыс.6 лет назад
The Fourier Series is a fundamental concept in DSP and has close ties to additive synthesis techniques. By generating a lookup table oscillator using the Fourier Series coefficients for a saw or square wave, we can finally control the amount of aliasing in our oscillators, but only by reducing their high frequency content.

Learn Audio DSP 4: Lookup table oscillators
Просмотров 8 тыс.7 лет назад
Wavetable oscillators are dope because you can use any arbitrary waveform. I play some bass lines and melodies using a quirky rectified sine wave and a regular ol' saw wave. We'll hear some aliasing, but that's ok.

Learn Audio DSP 2: Basic waveforms and sampling
Просмотров 18 тыс.8 лет назад
In this episode of my audio DSP series, we tackle basic waveform generation and the concept of sampling. These ideas are fundamental to many parts of audio generation and will come up again and again. We cheat a little bit and create waveforms that alias when played back, but you know, it still mostly sounds like the thing. Links to things I talked about in this video: Learn Audio DSP Part 1: G...
Learn Audio DSP 1: Getting started with Octave and making a sine oscillator
Просмотров 52 тыс.8 лет назад
Do you want to learn how computers make and manipulate sounds? C'mere and watch this video and I'll show you. This is the first video in a series of tutorials on audio DSP using Octave. In this video, you'll learn how to make a simple sine wave oscillator. We'll make some audio effects and synthesizers and stuff in a future video.

It seems the download link is no longer working. Could someone kindly share the files? Thanks!
If you're watching in 2024 the last line of code is deprecated so use audiowrite. something like this audiowrite('test.wav', tone, fs);
Очень интересная тема, здорово изложена. Спасибо Вам за это видео!
Best audio dsp tutorial I’ve ever seen. My hero ❤ my question now is how does the interpolation from but to bit work??? Thanks so much 🎉
Very nice and clearly explained
Ok i think i finally enjoy math now.
such a cool tech dude.....you are..... hope you a great youtube experience....

Dude you’re awesome for making these vids! I’ve always wanted to learn dsp programming as both a programmer and musician but I don’t have a math background.
Thanks for this effort !!! Looking forward for more videos
Why not Flowstone ? That's a really great program to see and ear instantly what we do in dsp.
Very very good. Thanks for the pointers to the other sources too. I found you after I found Rich Radke and when I got to part 4 of his series I started looking for help on Octave and found this series. NICE.
I had a terrible time because "l" and "1" look the same when typed.
I rewrote to this: %Duration and Tone %sawTone = @(l,t) repmat(linspace(-1, 1, t*FS), 1, round(l/t)); sawTone = @(d,t) repmat(linspace(-1, 1, t*FS), 1, round(d/t));
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?
Just so I'm clear, this code: bass(numel(bass) : numel(melody)) = 0; is extending the length of the bass vector by going from the final index of the existing bass vector (15) to the final index of the melody vector (16) and setting the value to 0 in a single step (in this case it's only missing one beat but if there were more it would just fill them all with 0 values).
It's near end of 2021 ... I just found this gem while looking around for working with octave for I/Q data analysis, I haven't found it yet. Anyone that could help me with any pointers to that is much appreciated.
These videos are so helpful! Thank you!
fantastic video!
Hi, excuse I have a questions. Which high-level programming languages can be used for DSP, spec? Can they be used for digital signal processors? Thanks a lot
Hi Dan, Very nice video. Do you have a video for cab impulse response?
Thanks a lot for sharing your knowledge.
whats the theory behind this
DSP theory says a linear time-invariant system can be perfectly modelled by convolution with its impulse response. An actual spring reverb unit is probably not perfectly LTI, but close enough that convolution gives a reasonably convincing impression of it. Since the spring reverb impulse response is just an audio signal, what I'm doing in this video is to try and reconstruct it from a model of some of its components that I analyze with the plots I show in this video.
Wow, nice video! I’m glad you criticized DSP for all of his ebegging and lies. I mean, to hear someone else use music to talk about the fact that DSP has scammed his fans dozens of times really brought it home. Great analysis, can’t wait for your DSP anthology.
At 11.38 when you plotted the values?what was chosen as x axis?
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!
Thankq
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
I've an issue!! wondering if I could get some help, im getting the error - error: zeros: conversion of 66461.5 to int64_t value failed
It looks like you are asking the zeros function to make an array that has a fractional number of elements. Try using the round, floor, or ceil functions to remove the fractional part of the size of the array and turn it into an integer value instead.
Same issue here using the exact code from the video, maybe it's caused by using a newer version of Octave. As Dan recommended using a round function made it work: instead of bassTone = zeros(1, bassNoteDur * FS); use bassTone = zeros(1, round(bassNoteDur * FS));
My octave is just opening the first of the two plots, but i used the exact code :/
Dsp tries it
Fuck this game. Nothing I could do.
Hi Dan, I recall hearing in one of your videos that you moved to Pittsburgh. Do you still live here? If so, let me buy you a coffee sometime! I'm working on some analog stuff that I'd love to show you. BTW, Loved your video on convolution reverb.
5:19 is that Dead Man's Tetris by Flying Lotus? Very cheeky of you ;)
yes!
Hey can anyone please help? I'm writing a different melody (No Surprises by Radiohead) and I'm getting this error: operator +: nonconformant arguments (op1 is 1x782636, op2 is 1x820030) - Which I think means that the melody and bass aren't synced up, but I'm using the same beat pattern (meaning melodyBeats and bassBeats are the same vector copied and pasted) so I don't really understand what the problem is.
UPDATE: I realized my mistake! For some reason copying and pasting the beats vector from the melody to the base confuses Octave because it thinks you want get different values out of the same vector, so I just had to make a new arrangement for the bass notes :) tl;dr Octave LOVES counterpoint lol
please continue making these videso! I cannot tell you how helpful they are and how good you are at explaining this extremely complicated stuff.
Please continue this series! Thank you
you act a lot with your glasses and eyes ,,, dont fake it just be yourself ... wearing a glasses and talking smart dosent need an effort , it shuld be natural ...
Yeah, you know all about sounding intelligent, completely naturally.
I can't get over how fun this tutorial is! Who would have thougt I'd have fun with a calculating program :D I learned way more than in my matlab class
This video is great! I decided on following the series and it's quite fun also :)
Nice and clear video thanks!! Can you do a video explaining what is convolution and how it works?
0:32 I make an LFO by taking a paper Puncher & Punching a bunch of holes in a plastic sheet then Rip the F...sucker through My S...finger Nails! Thanks for the video Mac!!!

keep making these videos, when ever you can, your good effort on internet will stay for generations
Thank you for sharing your knowledge on youtube
do you think i need to learn c and c++ for recording and dealing with the audio api with a daw ?
Isn't the Hammond Organ an analog additive synth?
Incroyable, vraiment un grand merci from Paris
Great video, sir! Really appreciate the work that went into this.
For anyone having problems saving the file 'test-tone.wav', the function has been changed. audiowrite('test.wav', tone, fs); worked for me. Hope this helps.... Also, great video!
Hey Dan, the second part of the video, when you synthesize your response, is crazy *awesome* !! I still need to understand some stuff in there ( like when moving from frequencies to phase values ), but seeing how to tweak things little by little was really super useful !! thank you for this !!
