DMR to ASL audio level
Peter Buckley
Thanks Steve, Please make a suggestion as your schedule allows. Symptom needing help: low volume audio coming back in from DMR side to Allstar side. My current Analog_Bridge.ini is below. Original entries marked with a # (updated entries right below those lines) Steve - I made the adjustments based on an earlier email (to the group) from you. Q.) How best to include the DMR Audio going into the Allstar side. 73s -pete N0ECT [USRP] server = 127.0.0.1 ; IP address of Allstar/Asterisk toASLPort = 32001 ; Analog_Bridge <-- ASL fromASLPort = 34001 ; Analog_Bridge --> ASL # aslAudio = AUDIO_UNITY ; Original Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN) aslAudio = AUDIO_USE_GAIN ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN) # agcGain = -20 ; Original Gain (in db) of the AGC filter agcGain = .5 ; Gain (in db) of the AGC filter dmrAudio = AUDIO_UNITY ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF) dmrGain = 0.65 ; Gain factor of audio from ASL (0.0-1.0) # dmrGain = 0.35 ; Original Gain factor of audio from ASL (0.0-1.0)

We are changing some of the defaults to point to the test reflectors. There are a few minor updates to the programs. Mike and I have been working on the documentation and example configs. I'll be updating the wiki with some of the samples. 73, Steve N4IRS

Peter,

Use: dmrAudio = AUDIO_USE_GAIN ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF) dmrGain = 2 ; Gain factor of audio from ASL (0.0-1.0) This is multiply by 2. If still too low raise by 1 until you get it where you want it. 3.5 is a acceptable number. Mike and I have been talking about tweaking these defaults. Steve

Thanks Steve, That DMR Audio increase tip - worked perfectly. The DMR side came up (what I needed) to get the analog listeners (Allstar) up to a good level. Our assigned BM/TG 31085 is connected to an old Analog Repeater system that covers most of western Colorado - Vail, Aspen, Glenwood Springs and Grand Junction. 73s pete N0ECT

If I make changes to the audio levels, do I need to reboot the system?

No,

Just restart Analog_Bridge systemctl restart analog_bridge

Thank you. One last question.
To adjust the DMR to ASL, can I use AUDIO_USE_GAIN? If so, which number would I adjust? I only see an option for agcGain. I need to increase my audio from DRM to AllStar.

Funny you should ask. While trying to write the documentation for
this we realized that the names and comments need fixing. For now,
here is the info:
toggle quoted messageShow quoted text
aslAudio = AUDIO_UNITY ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN) agcGain = -20 ; Gain (in db) of the AGC filter dmrAudio = AUDIO_UNITY ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF) dmrGain = 0.35 ; Gain factor of audio from ASL (0.0-1.0) aslAudio is the level from DMR to ASL you can use the following: AUDIO_UNITY No change in level from in to out AUDIO_USE_GAIN Allow change in level up or down agcGain is misleading, when used with AUDIO_USE_GAIN it is a number from 0.0 to 10.0 A number less then 1.0 is a reduction in level A number greater then 1 is a multiplier. .75 is 75 percent of AUDIO_UNITY 5.0 is 5 times AUDIO_UNITY.
