No. Decoder != Player. Please read the (very fine!) manual to ambdec. And then use any jack-aware player to play the files. I use mplayer and that works great. > I guess a friend who lives near to my home has at least 8 outputs for an > Envy24 sound card and at least a JBL 5.1 setup, so the 5.1 speakers > could be used for a minimalist ambisonics. Keep in mind that 5.1 systems are only a poor substitute for ambisonics set- ups. Even when using jbl-speakers, the set up is still different resulting from the different use cases. 5.1 is practically stereo. Its one mono for the voices (called center), one stereo for music and ambient (called front) and one stereo for special effects (called rear). [Forget about that extra channel for lfe which tries to be smarter then the user.] Ambisonics is really every channel with the same priority and use-case. It will not matter whether you use the set up with "front" at positiv-x direction or 130° rotated around the z axis and 30° rotated around the x axis (when using a full 3D rig). It will sound all the same. And the speakers in the room have to be set up for this. Also the speakers are all supposed to be equally away from the listener for best performance, with 5.1 the rear is supposed to be much nearer to the listeners than the front and center. You see ambisonics and 5.1 are different things. Because of that your (and my) aversion against 5.1 can not be held against ambisonics. And because of that a 5.1 set-up is only of limited use for ambisonics re-production. Have fun, Arnold
