Trying to capture the audio feed from an Asterisk meetme conference room. The VOIP interface encodes G.711 a-law audio at 8khz. Need to bring the audio into a digital broadcast environment. Using a MADI audio interface looks like a good means to output the audio from the server, but the broadcast cards (MADI / AES) only accept PCM audio 32khz.
Anyone familiar with any way to real-time decode the asterisk meetme G.711 8khz audio to PCM audio?
