Overdriven P25 audio

Bill N2WNS
Looking for the best audio settings for a DMR<->P25 implementation. It's being reported on the P25 side the audio sounds overdriven. DMR sounds fine. Settings are all defaulted.

I would try turning down the audio coming out of the DMR
Analog_Bridge in the [USRP] stanza:
toggle quoted messageShow quoted text
usrpGain = 1.10 Change it to 1/2 usrpGain = .60 retest.

Was there a change from the default? Mine from default is .35 on both Analog_Bridge_DME.ini and P25.

No change. Remember there are 2 level settings:
toggle quoted messageShow quoted text
usrpAudio = AUDIO_UNITY ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN) usrpGain = 1.10 ; Gain (in db) of the AGC filter tlvAudio = AUDIO_UNITY ; Audio from ASL (AUDIO_UNITY, AUDIO_USE_GAIN, AUDIO_BPF) tlvGain = 0.35 ; Gain factor of audio from ASL (0.0-1.0)

I'm running "in production" a DMR<>P25 bridge long time. Beware, there are two ways (DMR>P25 and P25>DMR) you need to adjust.:
