 App is actually recording in the chip, there are Special Programmers, but do we need it ? a small Speaker from an old TV is quite suitable to program or record sounds pulses or speech into the ISD1820 chip.

 By connecting the speaker Coil to the input via the separating capacitors and closing the First contact of the chip on the power supply, we can record a small fragment of speech, music and code. With a 50-Ohm clock resistor, the fragment length will be approximately 5 seconds.
