Audio Record/Playback Circuit

For what it is worth, most of these chips are solid state alternatives for the tape in telephone answering machines. So, the quality you should expect is on par with phone quality. There may be a few variants which allow you to choose your sample rate. The APR series from Aplus Taiwan is one of such chips. Using segmentation and playing fill-ins, you can build really long messages. Some examples would be the announcement systems on the train / bus.

Hmm, that doesnt sound too bad then. I guess the only way i will find out for sure is to actually order some and see how they sound. If it turns out that they arent suitable then i have another idea. I seem to remember FTDI making an mp3 player chip or circuit. I know thats probably overkill for a short sample but if i used that i could use it for the longer files aswell.

I will order some of the ISD chips first though and see how they turn out. Thanks.
