DIY sample looper device

[[email protected]]

Hi there, not sure whether this is the right group but I'm just looking
for some information.
Am not a DSP genius or whatever so I'm not quite sure whether this can
be done.
I would like to build (or buy a ready kit if possible) a device that
would play a single digital sample (doesn't have to be MP3) over time.
Tricky and unusual bit is that this device should loop the sample for
let's say 1 second but the starting position of the loop should be
regulated by some kind of a knob or gauge. I want to have a hardware
that will basically emulate the CoolEdit's selection loop function with
predefined sample and loop time. Question is whether someone have ever
seen anything like this as a kit? or how difficult would it be to built
such a device? I did some research but only things I could find that
would be close to this were single chip MP3 players. which I pressume
would do the trick but I don't have a clue how could I loop a sample
with a gauge on such thing?

Thanks in advance for any replies and please forgive me if this is not
the right group.

Relatively easy with say an AVR processor and an Atmel dataflash for
storage. How many do you want, and how much do you want to pay ?

How about an EPROM with resistor-ladder D/A, a few binary counters
and that's about it?
