Here is another interesting eLearning for DIY audio enthusiasts. Digital signal processing from the École Polytechnique Fédérale de Lausanne. With this course you will understand the basics of digital signal processing. The course does not focus explicitly on audio applications. But it might still help you to understand, what’s going on in an audio DSP and also what their restrictions are.
There is another goodie: the textbook for this course is available online for free. You can buy a printed version or the iBook version, but if you’re ok with a PDF file, you don’t have to pay for it. I just had a look at the textbook and it seems to be well-written.
However there is one thing, that some people may not like: There is a lot of complex algebra in digital signal processing. You will not just learn ready-to-use algorithms, but you have to do some algebra by yourself. If you hate math, you will not like this course.

While still many audio enthusiasts favor linear power supplies for their circuit, switching mode power supplies (SMPS) are used more and more. They have several advantages to linear power supplies. Not only are they usually more efficient, but also the switching frequency can be far outside of the audible frequency range. Even though you can use the circuit diagrams in the data sheets of available ICs, you might want to learn a bit more about this kind of circuits. In this case, the Coursera course “Introduction to Power electronics” is the right course for you. The course started today and you can attend for free.
Do you want to get a better understanding about audio circuits and loudspeaker designs? Then check out the free online course “Fundamentals of Audio and Music Engineering” on Coursera.
During this 6 week course you will learn the basic concepts of acoustics and electronics and how they can applied to understand musical sound and make music with electronic instruments. And you can even earn a certificate.
You don’t care about the technology and the technology, but love music? Then you might be interested in History of Rock – also brought to Coursera by the University of Rochester.
