I'm trying to work with my overseas vendor and they are not really providing a lot of information.
We are working on an educational toy that will give you facts and then asks questions.
We will have A LOT OF human speech and a handful of sound effects.
I'm trying to fit as much audio on the chip as possible.
What sampling rate should I use for voice? 11.025 KHz? 22.5 KHz? What sampling rate should I use for the sound effects? 22.5KHz?
The speaker is a 'cheap' toy speaker...not high fidelity.
