Audio Design

Good, yo ualready know everything. An audio amplifier is simply an amplifier with very limited bandwidth ;-) (hidden grin).

Audio amplifier is a very cheap amplifier.

Man, what lame replies.

If you are referring to a power audio amplifier, try Randy Sloan's book:

Nelson Pass has a few papers: Also Marshall Leach:

As an undergraduate, amplifier design is probably interesting, but probably won't lead to a job in the field unless you start the company yourself. But knowing analog is a valuable skill. Not everyone can do analog. It's a black art. Doing it in integrated circuits is even more of a specialty. Making reliable analog integrated circuit, i.e. stuff that actually works and can be manufactured in volume is even harder. Though I've done analog integrated circuit design as both consultant and employee, the consultant does the design but doesn't get the follow up problems. Making good analog products takes a combination of intelligence and being an anal retentive mono-maniac.

You might try one of Douglas Self's books:

Self is not part of the HiEnd voodoo subculture, more into mixing consoles and amplifiers that simply must work.

There's some fun on his website, too.

Ditto on Doug Self.

If our budding engineer is thinking of a senior project topic, I think yet another investigation into clock jitter and data conversion error would be worthy. It is probably still true that you can't make a 16 bit ADC, hell, a S/H, based purely on the slew rate of a 20KHz signal and the jitter of the clock. There are some areas of engineering like spectral analysis and clock jitter that seem like an endless source of paper topics.

** There is no such book. ** Not even faintly relevant to real world audio design. ** There is no such book. ** You have no real experience in ANY kind of design.

** Explains a lot.

When you learn a whole lot more about the outside world - you just might just begin to see why your post is totally absurd.

Leo, Phil is our problem child. Just ignore him.

I'm sure he will reply to his post with a lot of hate speech and such.

What apsect(s) of audio design?, there are many...

As others have said, Doug Self's book is the usual suspect. There is also John Linsley Hood's Audio Electronics:

And of course you can do worse than troll through the articles on Rod Elliott's web site:

Read your textbook, do the exercises, listen in class and do your homework diligently, and all will be revealed to you.

If your local library is on the Dewey decimal system, look in section 621.

Have Fun! Rich

Thanks for the links guys, I am able to get Audio Power Amplifier Design Handbook so that should get me started. Also I see some interesting papers in the links. I do not expect to read them just now, but I=B4m sure I=B4ll get to read them sometime. I=B4m not in a hurry anyway just looking to be pointed in the right direction!!

Cheers!

Back in the day, I used to read RCA Solid State Power Circuits. I'm not sure if it did any good !

Speaking of the right direction... Audio is very good area for hobbyists =

but not so good for the professionals. The HiFi and pro audio niche is=20 very small, the consumer audio is extremely cost sensitive. So the=20 engineering challenge is usually *not* about achieving the ultimate=20 parameters but about squeezing every penny while keeping the reasonable=20 performance and good reliability. As consultant, I design the audio=20 amplifiers; and in our days it is mainly Class D. With all due respect,=20 the Doug Self and Co is mainly of the theoretical and the historical=20 interest, rather then of the practical usefulness.

** No it will not !!!

Doug Self's book is falsely named -

it is certainly NOT any kind of design instruction book.

Also I see some interesting papers in the links. I do not expect to read them just now, but I´m sure I´ll get to read them sometime. I´m not in a hurry anyway just looking to be pointed in the right direction!!

** The only pointed thing is your head - pal.

I spent most of my youth in that section - these days the system seems to have gone by the board and I have to ask the librarian where e.g. car maintenance books are rather than just following the number sequence round the shelves.

Ok. My interest as an undergraduate is to take interest in different areas of electronics. As of now i'm interested in audio, I will try to read as much as possible and see whether I like it or not to pursue audio design oriented carrer. What I'm trying to say is that historical and theoretical interest is enough for me right now, as I don't know nothing about it. I appreaciate the advice though, I will take it into account in the future.

Seconded; For good plain down-to-earth quality audio engineering and hitting the nail squarely on the head, you will not find any author better than Doug Self.

Understood a word of it ?

Spotted all the opinionated bullshit ?

The history of sound reproduction is pretty interesting. There was a push for 3 channel sound, since the hole in the middle was discovered pretty early. The problem was it was easier to do two channel sound on a phonograph.

Alan Blumlein was a great contributor.
