Subaudio recorder design anyone?

Thanks to everyone who responded to my question about using MP3
recorders for subaudio.

I tried this with a borrowed unit and it gets seriously degraded by
the filtering. These recorders are also too small to modify
internally.

To take another approach, is there a relatively simple on-board design
that would allow me to record and playback 5 minutes of 1-25 Hz
arbitrary waveforms (not pulses)?

A sampling rate of 2056 Hz would suffice. Circuit should be
self-retriggering to play indefinitely.

Unfortunately, I am not a proficient programmer. Is the above, with
software, available anywhere as a kit, project, PCB, schematic, etc.,
in ready-made form.

Or, maybe an existing PIC or Atmel project that is close enough to
modify.

I have the feeling some here could whip this up in a few evenings. If
so, is anyone interested in doing a prototype at reasonable cost?

Please contact me on list (not by reply) and I will return by email.
