Dear list!
I just spent a lot of time finding a good setup for telephone
interviews. In case someone else is interested for making podcasts or
live shows of some sorts, I thought I'd share the setup:
# Hardware
Laptop, smartphone, USB interface, iRig 2, microphone, headphones.
XLR cable for the mic, 2 Jack - Jack 1/4" TS cables, USB cable.
I'm switching between an Edirol UA-25ex and a Focusrite Scarlett 2i4.
Proper connection of the phone to the setup was a headache and I spent
quite some time testing a range of adapters. Most of them require an
electret mic to function, which does not go well with my setup. Thanks
to https://m.youtube.com/watch?v=wl6YuVu_v_g for pointing me to the iRig.
# Connections
Mic > USB 1
USB out 1 > iRig instrument input
iRig amp out > USB 2
iRig < > telephone
iRig set to FX
To cancel echo from my own voice the Input / Monitor selector on the USB
needs to be set almost fully counter-clockwise (almost input only).
# Software
Kubuntu Studio 20.04, Ardour 6.6, Studio Controls 2.1.64, Carla 2.3.0,
Ubuntu studio backports PPA.
# Software connections
1. Set Ardour to handle monitoring
2. Set Ardour Master to send L/R to System playback 2
3. Set up a mono foldback bus in Ardour for mix minus (everything except
the caller). Foldback sends to System Playback 1
4. Use Carla > Patchbay to disconnect System playback from pulse_out
Using a cheap Shure PG58 mic this setup is close to noiseless, even in
my bedroom home office :-)
Regards,
Alf
