hardware - Low-cost sound chip - Stack Exchange
https://retrocomputing.stackexchange.com/questions/11866/low-cost-sound-chip
In electronics, there's often no lower limit on the price, a chip of similar functionality can cost either 0.2 USD or 20 USD, depends on the supply/demand, how many specialized features you need, and how good/bad you want it to be. For personal projects, 2 USD is low-cost but for mass production, low-cost means 0.2 USD.

https://electronics.stackexchange.com/questions/26632/what-are-some-typical-low-cost-microcontrollers-and-chips-that-are-used-in-elect
Any 8-bit low cost, low power microcontroller can be suitable for this purpose. About cost effectiveness, a very important factor is the number of chips that you buy in batch; for a hobbyst, that buys 1-10 devices every time, the unit price will be much higher (more than double, shipping excluded) compared to what a manufacturer pays for 10'000 ...

In regard to the tech behind the chips, the TDA1387 takes some beating as it continuously recalibrates itself on the fly so doesn't require the usual extreme resistor matching achieved in other manufacturer's offerings by laser trimming. Its also absurdly cheap as the chips are recycled from old 'Soundblaster' PC cards.
