Hi,
I am thinking on working on a project where I would make use of a speaker and sound decoder chip , to transmit digital signal into audio.
I am at a problem at part selection. I can't seem to find the right part for the job. I just need the part to be cheap, less than $5 and work on human voice only, no music. I have been searching on mouser and digikey but no luck. The data sheets say the parts are used as multiplexer and/or amplifier.
I don't have much knowledge at this subject, voice thingy and I don't think I have enough time to study graduate level books all by myself. Any crash course or VERY useful introduction book from the experts in the field?
I have had some people buy some boards and a sound chip and they could listen to their speech, but it was only for 30 sec recording, and the quality was horrible. I don't have any limited memory. The design would be an embedded system.
Thank you.
