Subject: | [Linphone-developers] disable all voice comfort functions |
Date: | Wed, 9 Jan 2019 19:13:14 +0100 |
I am a scientist at the Fraunhofer Heinrich Hertz Institute in Berlin. We use Linphone to control drones via the voice channel of mobile network. This has the advantage that voice data is prioritized in the mobile network and thus a short latency is guaranteed.
To communicate with the drones, we use Linphone on the ground station side. But now we have the problem that not all voice comfort functions can be switched off. We already have some settings in the Linphonerc file:
[sound]
ec_filter=MSWebRTCAEC
playback_dev_id=WASAPI: Lautsprecher (VB-Audio Virtual Cable)
capture_dev_id=WASAPI: CABLE-A Output (VB-Audio Cable A)
ringer_dev_id=WASAPI: VoiceMeeter Input (VB-Audio VoiceMeeter VAIO)
echocancellation=0
echolimiter=0
agc=0
remote_ring=C:\Program Files (x86)\Linphone\share/sounds/linphone/ringback.wav
playback_gain_db=0.000000
mic_gain_db=0.000000
Using only this Codec:
[audio_codec_4]
mime=PCMA
rate=8000
channels=1
enabled=1
We really only want to send and receive the data 1:1 as we generate it on the PC. However, it seems that the reception and the transmission signal influence each other in some way at the moment.
Can you tell me how to disable the corresponding functions
in Linphone?
Kind regards
