Progress Report on this dead thread:
I got some free time to experiment. I was able to make a attempt
using a ATtiny26. I used the atmel's internal ADC biased to 2.5V with
100K resistors to +5 and GND and audio coupled in with a 0.22uF
capacitor. For the DAC I used a resistor ladder built

Here is a clip of what the circuit sounds like, but the high frequecny
distortion wasn't so faithfully reproduced as my laptop sucks.
BTW: This used to be Don Henley - Sunset Grill which the MP3 I had
which is a 128Kbps Stereo was upconverted to a Audio CD and played
into the DDL

In the future I will use a dual op-amp for the audio in and out as it
will do a better job of biasing to 2.5V than the 2 resistors.
Stay away from the LM324, nasty crossover distortion.
My recommendation: TLV2372 (dual)
This would work, to solve the aproximation scheme to make the samples
fixed at approx 2.5K but the ADC is still not fast enough for complex
audio. I am thinking of a 8bit 44Khz ADC for cost reasons. I don't
know if I want to use a Serial DAC or a resistor DAC. I just got some
Tiny45s to play
heh-doesn't sound any worse then a Real Audio stream ;C}
Indeed, not bad for a one-chip winder. :)

Ted,
I'd almost beg to buy some of your chips if you can
find them. Please email me direct if you or anyone
else has any of the 4096 delay lines, which you would
sell.
thanks

I know I have a box of 24 of those 4096's, but haven't
seen them since I moved. I'll dig into the boxes later
What is the exact part number ??? I bought some bucket brigade chips many
years ago from digikey, and can check what I have left, which was most of
an IC tube as I recall..

This is the first time in 20 years... I won't be doing this
again any time soon :)

I would prefer to do the project with ATMEGA-8 as well. I currently
use Bascom-AVR to program with, but I am more of a hardware designer
and not a software programmer. But space wise for a 2 chip solution I
would go with serial ram and a Tiny13.
Projects I have done with the Atmels:
