Power efficiency is a good reason to use class-D amps instead of class A-B amps. Class-D amps dissipates much less heat than class A-B amps, and are returning power to the supply; this power can be stored temporarely in big filtering capacitors (in parallel with the supply output); if big enough,

Re: [Sursound] Flac for FOA or amb files?

To assemble FOA files in amb files, I use channelx and interlx from the CDP suite: http://www.unstablesound.net/cdp.html channelx is to extract channels to mono files, while interlx is to interleave mono files in a proper amb file (with the appropriate WAVE_EX Ambisonic header) that can be correc

Re: [Sursound] Ambisonics in Ogg Opus

Thanks Martin! I tried Opus a while ago for ambisonics, and it works well. But I had to hack the encoder so it would not combine channels together, because the default behavior is to consider multichannel streams as quadraphonic, 5.1 or 7.1 streams, with optimization for those formats, that could

Re: [Sursound] Ambisonics and IMAX 12.0

Hi Tim. I'm not an expert, and others on the list could much better answer your question. But as far as I know, irregular arrays like the new IMAX 12.0 are not well suited for ambisonics reproduction. There's at least one tool to create decoders for irregular arrays, depending on the exact positi

Re: [Sursound] Muti-channel ambisonic audio in sync with video

It's already possible to play a multichannel audio/video file using VLC (or other players) while decoding to ambisonic; it's a matter of configuring the system to redirect the multichannel audio of the video player to an ambisonic decoder, using a sound server like Jack. -- Marc On Fri, 9 Sep 2016
