Audio Signal Processing for Music Applications

[Siekmanski]

There is a free online DSP course at Coursera (Stanford University).
The title is Audio Signal Processing for Music Applications.

Here you can sign in for free: http://coursera.org/course/audio

And not to forget, Marinus:

Yes you will earn an Statement of Accomplishment if you do well in the course.

Hi Gunther,

They are using the Python programming language for the assignments, not my cup of tea.
I'll just follow the course without doing the programming assignments, so no Statement or Certificate for me.
But, hope to learn a lot for my own use.

At this moment i'm rewriting my old Fast Fourier Transform routines, so this course might be handy.

Marinus,
You made me curious, so I found this page comparing Python to Basic. I guess one could get used to it, but it's not my cup of tea, either (hey, aren't you coffee drinkers in NL??).

[Siekmanski]

Yes, we are "koffie drinkers" in the Netherlands.  :lol:

i'm going to be away for a few weeks, but let's see if i can keep up - lol
python - probably not, but i may give it a whirl
i wonder what they'd think if i turned in ASM code   :P

[Siekmanski]

i wonder what they'd think if i turned in ASM code   :P

Let's do that.  8)

Okay, go forward fellows.  :icon_cool:

Hi,...Siekmanski (Marinus),
This is a fascinating topic (I'm not being a wiseass for once).
Years ago, while I was playing around with some song writing software that I had (Cakewalk Sonar),...I had the brilliant idea of writing a music file format analyzer based on DSP concepts.
I somehow acquired a book about Digital Signal Processing from a used bookstore, and, began my quest. The mathematics is mind-boggling. I almost made it through Chapter One (Introduction), and, couldn't understand it at all (and, it was written for C programmers).

At this moment i'm rewriting my old Fast Fourier Transform routines,...

Do you REALLY understand the: Fourier Transform ???

...I'll bet GUNTHER has a clear grasp of the subject,...

[dedndave]

i guess he does - see reply #2   ;)

which is easier to implement in hardware or software than it is to understand the math - lol

[Zen]

How does a person express an irrational number in assembly language ???
Let me make a guess: by pretending it doesn't exist,...

[dedndave]

perhaps as a complex number
but - you factor out the "i" part - same way they manage them in algebraic equations



i = -1^1/2

usually, the lower-case Greek letter Iota is used
oddly enough, i don't find a good picture of how you see it in math books   :redface:

[Zen]

In all honesty,...I think that (Marinus) Siekmanski should get some kind of MASM Forum award for posting the source code to his programs.
This really is a uniquely valuable contribution. I have to admire his intelligence.

...But, maybe,...it's just that I'm an intellectual reprobate,...

[dedndave]

you saw all the math on the wiki page, right   :shock:

here's a simplifed block diagram that might be used for hardware or software
so - it's not nearly as bad as you might think   

[Zen]

DAVE !!!
I have an excellent sense of humor,...but,...
