Hi all Because of those battery concerns, we are installing our setups with a small audio mixer and linking the lapel mic to the right audio channel and the ambient mic to the left audio channel.
Then we have made a new operation in Matterhorn to extract the audio from the right channel before processing. So we have a "backup audio" that would be not as good, but still usable. Of course the extract audio operation could be smarter, and select automatically the left channel if there is only noise in the right channel, but we aren't there yet Regards Carlos Turro Head of Network & Media Services Universidad Politécnica de Valencia De: [email protected] [mailto:[email protected]] En nombre de Rubén Pérez Enviado el: miércoles, 09 de febrero de 2011 17:05 Para: Opencast Community Asunto: Re: [Opencast] Microphone recommendations Hi all: We are not still considering this issue, but I have one concern: what if those mics run out of batteries? How do you deal with that problem? Thanks and best regards 2011/2/9 Carlos R.

Some early experiments I have been doing with CMU Sphinx show that the speech recognition engine is very sensitive to echo and reverberation (as well as background noise), so we are looking at lapel mics and head-mounted mics. For venues where amplification isn't necessary for the audience, I was also wondering whether bluetooth headsets would be an option?
