I'm not sure if a generic phone's DA converter can match the signal quality of a specialized circuit.

- jack12 7y agoThe Pocket Operators are just a generic DAC+amp chip, the Cirrus CS42L52. The DAC is driven by a 48MHz MCU with just 32K of RAM. If it were purely a question of technical / hardware capabilities it would all fit into an app ten times over. http://hackingthepo.weebly.com/ http://hackingthepo.weebly.com/ has a terrifically detailed teardown of a PO-16. Or SiLabs (the MCU's manufacturer) did a marketing video / interview with one of the Pocket Operator's designers about the hardware design: https://www.youtube.com/watch?v=ZjrOnlMkJHU https://www.youtube.com/watch?v=ZjrOnlMkJHU
