Roman,
OK, wasn't sure before. But I am now.
I have an import function that works on ANY PIC. (ASM or PBP)
With a single exported btc file format.
Conversions to 14-bit data or retlw are handled by MPASM (if necessary).
Just need to make the player work with each type, and I'm good to go.
Please HOLD!

IMHO the attached sample works at 22050Hz 1 bit
it uses a 12F675 @20MHz and an external I2C eeprom (24C256)
The i2cread statement needs about 170uS to respond(@ 20MHz); i suppose that 44100Hz sampling rate can be obtained.
Have fun.

Obviously the eeprom must be pre loaded with the binary file (filename.btc)
A simple file transfer through com port could be interesting.

You can go to Romans website for a schematic, and description of how it works.
