Audio Quality issues on Echolink
Has anyone had problems with very low outbound audio to echolink connections? The audio reports from the Echolink side are very thin audio, no highs or lows and low level. I have went through my RF link and also through Webtranceiver with the same results. If I do parrot mode on my link, my audio sounds great. The issue seems to be in the interconnect to Echolink. Also I tried adjusting the link TX & RX echolink audio levels but I can't hear any change no matter what amounts of + or - gain I put in the etxgain or erxgain statements in the echolink.conf file. Any ideas??? Bill Hurlock CPCommunications 856-234-1661 Home Office 856-264-1010 Cell 914-345-9292 Ext.429 www.cpcomms.com WA2TQI Providing Solutions for Audio and Video Communications

Crap codecs from when Windows NT 4.51 was current, technology that has not been updated in any meaningful way since it was released, and a big dose of NIH when you try and suggest Jonathan do anything about it (shades of Cameron)? FWIW, mine sounds pretty poor, but, then, considering what others sound like, people are used to crap audio on echolink, so no one really does anything about it. Just my opinion. -- Bryan In this world, you must be oh so smart or oh so pleasant. Well, for years I was smart. I recommend pleasant. You may quote me. Sent from my MacBook Pro.

well as I understand it - the etxgain= statement goes into rpt.conf, not echolink.conf. and you probably need to do an asterisk restart to make it effective. I have been happy enough with the default settings, but I am guessing if you have nothing in your node stanza (in rpt.conf) you will be 3 dB low on transmit audio. Remember that E/L is GSM ... same thing they use on overseas cell phones. So if it like a bad overseas cell phone call, then you have it perfect.

Thanks Ken, That did it. I have it all tweaked in now and the sound is much better. Not getting any complaints from the Echolink crowd any longer. I wasn't sure where the 2 gain statements needed to be. I guessed wrong and had them in echolink.conf. So now I have that Hi Fi audio from GSM land ........
