Switching Inputs

[Kavya]

Hello,

I want to switch inputs to teensy audio board between mic in and line in using slide switch.
What are the libraries that I need to add to do so?

Thank you

Hi,

If you want to plug in an audio source instead of using the built-in microphones, you can use the information on this post:

Changing to External Microphones

I’ve received questions about how to switch the Tympan from using its built-in microphones to using external microphones via the red microphone jack. The simplest answer is to look for a line that says “inputSelect”. By default, the example programs probably look like: audioHardware.inputSelect(TYMPAN_INPUT_ON_BOARD_MIC); If you want to use an external microphone via the microphone jack (and if you want the Tympan to supply a voltage bias to power the mic), you’ll want to change this line of…

Since you said that you want to use it as a line-in, you’ll want the option that says: TYMPAN_INPUT_JACK_AS_LINEIN

As for the other part of your question – using the slide switch – the only slide switch on the Tympan is the power switch. That is not a programmable switch. It’s hard-wired as a power switch. Sorry.
