Thank you Mike.
I know that Microchip has an encrypted, or so, unique serial number in some PICs but could not find that info in the parametric search. I can't recall how it is called.

esp8266 , audio in littlefs partition in flash would nail it, files can be modified with simple https browser i/f
on the devices own self generated access point
Warning I'm not a teacher
You mean ESP with in Arduino IDE, which needs good grasp of C, right?
I do not feel very confident on that IDE for a client project.
Thanks though,

Depending on the samples and quality, you may find that you need quite a bit of storage (SD card with SDIO interface). The power of the PIC to handle raw samples may be severely short to get a reasonable output. I suggest you look at the VS1003B MP3 chips that you can throw the samples at. This way, you do not need too much processing on the PIC.
another option you can evaluate is available on http://elm-chan.org/works/sd8p/report.html

Jerson: Thanks for the info. The AT tiny is unbelievable!
Mike: thanks for the link.

We were doing this with an ISD5008. When that was discontinued we started moving into an ISD4003-08MPY. That was recently discontinued and are moving into an ISD17240. With a 4KHZ sampling frequency the 17240 will give you 8 minutes of record/playback.
