How can you separate all input jacks as independent input devices on a phone?

To separate all input jacks as independent input devices on a phone, you can use a specialized audio interface or a USB sound card that supports multiple inputs. This device connects to the phone and allows each jack to be recognized as a distinct input channel by the operating system. Additionally, using software that supports multi-channel audio input can help manage and route signals from each jack independently. Ensure that the phone’s operating system and applications are compatible with this setup for optimal functionality.
