I'm using Speex to bridge calls between an out-of-state Asterisk box and a local FreeSWITCH IVR. This works great, but I'm having to do needless transcoding on the FS system to play the IVR .wav files. I tried using speexenc to generate speex versions of the files but the audio is garbled (sounds like a screech). No errors or warnings are generated on the console when playing the file. I'm only using 8000Hz, mono files and generate the speex file with -n (narrowband) argument. I believe speexenc generates the files in an ogg container, so perhaps this is the problem, but I'm not sure how to get around it if it is. In any case, if anyone knows of a recipe for creating speex files that mod_native_file can use, I'd appreciate a pointer. Regards, Cliff
