Ya, That is why I haven't used them. 🙁
Some company's require you to have your own domain name for a business email address.
I just haven't got that far yet, TI, AD and LT has been good to me so far.
ST and Intersil cut me off for some reason and they don't have a whole lot to offer anyhow. 😉

Perhaps i should have used my student mail. Oh well silly me, now i tried to make another request, next time i will use the other mail. Pretty damn annoying 😉
What about using the pt2314. 4 channel, treble, bass, balance in one chip on the i2c interface.

Would the PT2314 allow stereo volume control and the two other channels to be used as a form of "automatic" loudness control, that is as volume rises, the amount of treble and bass bass would decease?

I've done this, it works really well. Details here:

It is also used by a number of high end manufacturers. I'm now working on a new attenuator module based this method and a 16bit TI DAC.
Ahhhh,ha,ha,ha,ha....Either way they get ya!!
I have sent two emails to ST this year and I get a response back saying that it was directed to the proper department but I have yet to hear anything back!!!
I just saw a post from Toms hardware about getting a free domain name but I am not sure if it is legit or not.
I don't want to use the business name I have used for the last 20 years just for them to pull it out from under me and sell it !!

Thanks for the reminder Maxw, I do remember that thread.
I did just find some newer 8bit multiplying Dac's at TI
The have one that is a dual but I haven't checked out the data sheet yet.
jer 🙂
P.S. It looks pretty cool....No SPI....Parallel input dual 8bit Mply Dac TLC7628,
http://www.ti.com/product/tlc7628
Ad has one too!!! 🙂

just came across this while doing my morning net.reading:
PiTFT Mini Kit - 320x240 2.8 TFT+Touchscreen for Raspberry Pi ID: 1601 - $34.95 : Adafruit Industries, Unique & fun DIY electronics and kits
it might be worth considering, using the beaglebone black or rasp-pi as the controller instead of using classic controllers like pic or arduino.
then you can do so much more and also have a proper ip-stack (ie, webserver) there for really serious remote control 😉
just a thought. as the tiny linux boards become cheaper and more common, they are eating into the controller hobby market.

I have considered RPi, Beaglebone or even Cubieboard. The only problem in my opinion is the power consumption. But its worth reconsidering, i think my last measurement showed that the RP draws somewhere near ~2W in idle mode.
But if we can find a excuse (which we most likely already have) and great energy friendly way of implementing the ARM-beast while maintaning the remote control capability im pretty open.
the BBB is the better board (in many ways), but both have a LOT of community support. and of course, it is very easy to do software devel on those systems. controllers are harder, but 'everyone' knows linux these days.
what I wonder is: how well can those systems keep up with realtime things like scanning rotary encoders and not missing events if the user turns it too fast. there might be a need, still, for controllers for some things; while the main processing can do the UI, ip-stack and even direct music playback (mpd).
the small board controllers change a lot over time, and so I would not design -for- a specific linux board, but rather have a serial port or something on the back of the preamp chassis that talks to the 'linux board of the day', whatever that is at the time of the build. in 6mos it could change, and so I would not embed a linux board -into- the project but design for a generic host controller over serial or i2c.

I dont think realtime will be a problem in such a small application, but really it depends on how much you squeeze the ARM processor and for which purposes. Running eg. a AirPlay station and a very lightweight webserver wont make a RPi kneel, but any time of the day i would go for a Cubieboard2 if i wanted to run crazy apps.
Its also quite limited how violently you turn the knob on the amp, people usually do it rather slowly and i did not plan to use a very high resolution encoder for the purpose.
I definetly agree with you that it would be smarter to move it to a serial device instead, define a API and let people choose whatever they wont in the other end. It would be sad if RPi suddenly died and our project went along in the hole.
+1 to that!
Yes, I have been giving this a lot of thought as well.
The ST board is great for what it is worth and will serve as a stepping stone for me.
But, I think my ultimate goal will require something with a bit more power even as simple the task may be as recorder, and, my childhood dream of a massive super stereo unit with a touch front panel that has lots of audio power.
This was not exactly possible when I dreamed this up at age 15, now such devices are everywhere.
Depending on the complexity even just a decent 18F PIC my suit the purpose or even something in the 24E,24H and 30Dspic series.
As these will be around for for quite sometime and have lots of support.
Now that we have gotten over the Who Ha of the desktop running in the blistering 4-5Ghz range, the latest of these little boards really intrigue me.
Much like when I used to hook stuff up to my Vic 20's and hard drives up to my Color computers that actually worked.
Being able to support a file system is almost a must considering it is basically necessary when using Flash storage and such.
Lately, I have been trying to figure out what to do about having a massive amount of working memory and then be able to store it to flash or something for safe keeping until the next session.
Flash is typically only rated for 100,000 writes, This amount of cycles add's up fast in the audio world and would be shortly doomed for failure.
It takes approximately 2GB of raw data to do 24bit 192Khz for 1 hour.
Transferring that takes some time as well, especially to flash!!
Sure the serial interfaces save board space, but it just seems more of PIA sometimes, I guess that is just me, Because I am not yet accustomed to today's way of programming yet.
What I want to do, can be done so much easier using parallel methods, But yet I have seen what I want to do be done with just 3 or 4 chips as well!!!
That Cubieboard2 looks pretty cool and has much more power than the ST board I have.
But the display you guys mention already comes on the ST board for the cost of an add on, this is hard to beat but doesn't make it the best. 😉
I have been watching these new little boards very closely lately as they are quite impressive.
But, On the same note the more powerful these things get and the more complicated the software gets, and this slows down the processor to the point that a simple little microcontroller can do with such simple tasks much faster.
If you were to market this thing the complexity adds to cost and should any one of those chips go bad, Then what!!!
Who is going to take the time to repair IT?!!!
I have had my share old equipment failure on some very fine products that I have had for the last 20 years and now I can't get any support for them.
For me I have about another 20 or 30 or so years to go and then I will be done with this world my self !! He,he,he
But it has been a Grand Ride !! 🙂
It all depends on your goals though.
Cheers !!!

I would ask for a tl;dr of that, but even that, I would probably not get all the way thru.
