Audio player

[peterdeco1]

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.

You mean ESP with in Arduino IDE, which needs good grasp of C, right?

i do , never tried it but it looks straight forward

cannot see how you can get in between df player and sd card to decrypt a file, you need to drive your own dac or pay for a proprietary
system that secures your audio data

I just remembered. There are these series of chips from Aplus that do exactly what you want. They are available in various capacities and can be segmented. So, you could record a few segments and then play them in any order you want perhaps even chain them together. This one I have used APR48000 in the past.

The APR and ISD chips are basically meant for human voice and not high fidelity. They're inteded for TAM (answering machines) use.

Hi Jerson.

Thanks for the info. The Aplus and especially the aPR33A3 might be exactly what I need.

Do they have distributer? Mouser or Arrow do not carry them.

Also the idea of ESP32 that Richard posted is a good alternative. Thanks for that too.

Hi Ioannis

Not sure how you can order Aplus where you are. Perhaps you may need to buy direct from the manufacturer in Taiwan. I used to source mine locally from a distributor in tiny quantities.

Best wishes
