StereoPi records only mono audio?

[StereoPipi]

While experimenting with my setup, I noticed, that the enabling of audio only records mono sound. I attached a Tascam stereo recorder, which is used as a USB interface. I want my StereoPi to be stereo, in picture and sound... What do I have to do to achieve this?

Hi StereoPipi,
Well, your question is really unexpected for us! We used mono mic only.

But I can suggest a solution for you.
This script is responsible for video record:

Code: Select all

opt/StereoPi/scripts/loop-record.sh

If you open it, you can find recording row:

Code: Select all

./bin/recorder -e udpsrc port=3003 buffer-size=200000 ! h264parse ! queue ! mux.video_0 alsasrc device=plughw:1,0 ! "audio/x-raw,channels=1,depth=16,width=16,rate=44100" ! voaacenc bitrate=128000 ! aacparse ! queue ! mux.audio_0 qtmux name=mux ! filesink location="$RECPATH/record-`date +%Y%m%d%-H%M%S`.mp4" sync=true

Here you can find audio options, in our case "audio/x-raw,channels=1,depth=16,width=16,rate=44100"

So you can set 2 channels for your setup, and this should work.
I have no stereo microphone to check this out, and I will be pleased if you can test this stereo sound mode.

Realizator thank you for you answer. I tried it, but with a funny success I get recordings, but most of them I can not view (viewer does not even start).
Those who can be watched, have mono audio.
...still searching for clues...

StereoPipi, as I mentioned we have no such experience with stereoscopic sound. But if I will face such a problem, at first I try to look at input devices names recognized by the system. May be installed drivers does not support stereoscopic sound or other issues.

As we used pulseadio, you may look at the devices list like this:

Code: Select all
