Codec for low dynamic range, noisy (rf crackle) speech? 2018-10-18 21:02:31 I'm helping a bunch who have a couple of Ye Olde Analogue radio repeaters scattered about the mountains to help hikers and hunters and search and rescue.They have a "keep an archive and listen either live or to archived recordings via the web" service. Very useful if a hiker in distress said something nearly inaudible and you want to go back and confirm you heard the right thing.I think they are using the wrong audio codec for this and I'm looking around for something better....* The audio quality is Bad Bad Bad by modern standards, mostly due to range, low power hand held transmitters, intervening dirty great mountains, weather, and RF interferers (eg. some farmers rusty electric motor).* The dynamic range is low.* There is substantial "crackle" interferers.* There is substantial "white noise" from RF and various components.They have broadband connections from the repeater stations to the cloud servers. So bandwidth isn't the limiting issue, audio quality is, and latency is. (Ever tried to have a conversation where the audio lags terribly?)Part of me says "Go lossless", but the utility might be increased by a codec that is good at emphasizing speech and losing crackle and white noise.Which open source / patent unencumbered codec would you recommend?
