Split input/output

[tmoo...@aol.com]

Question.

Is there any way to separate output and input?

Generator output to Bluetooth, Analyzer input from calibrated microphone.

Thanks.

I don't see why not, but I have no idea how to set that up on the phone. Maybe someone else does?

I believe I have found away around my problem. Downloaded the Lesser Sudioswitch App (I'm using Android 10) This app allows you to separately direct audio input and output. I'm not sure if the pro version is needed or not. The app is a bit confusing to use, not much documentation available, no support group, but I got it to work.

The easy way is a splitter cable (I've made several from dead headset leads), though if you have a Dayton mic it already comes with a headphone socket. It's a simple way to check the phone's mic input frequency-response (the AudioTool generator response is pretty flat).

Let's see if I understand you. I think we are talking different uses here. I need "Generator output to Bluetooth, analyzer input from calibrated microphone."

I could plug in Dayton mic. That gives me mic input.

Make cable. (no need make, I already have a commercially made cable that will work). Connect cable to an external Bluetooth transmitter. (and supply power to external Bluetooth device)

Is that what you are saying? Sound workable, but a physical kluge.

I'll stick with my method. 100% in my cellphone. All software and builtin hardware . Yes, Lesser Sudioswitch App adds software configuring complexity. Configure Lesser, run audio test, reset Lesser back to normal use. But, as my need for split input output setup is rare, I go the software only route.

Thanks for your input! Can you get back to me with more detail on your setup?

(I'm assuming your phone has a 4-pole 3.5mm socket) My cable - 4-pole connector (from a dead headset) to a 3-pole socket (audio out) & a 2-pole socket (mic in). This allows me to send the generator to the sound desk via a standard cable, or via a belt-pack radiomic (in your case a Bluetooth setup, but a radiomic allows you to walk any size room). I could just use the Dayton, but the cable allows me to use any electret mic with a 3.5mm plug (I often use an MKE-2 on a short lead, to save damaging the phone's connector if it gets dropped). To check the response of the phone's mic circuitry I can join the 2 sockets with a short stereo to mono cable, with an inline resistor (value not critical - I use 2k) to save overloading the mic input.

I'm old-fashioned, so for anything critical I much prefer a piece of wire to another piece of software, but if you are happy with the Lesser then stick with it.
