You would have to stream to mplayer from the url in order to do this with netflix, I think. Here's the blurb from the mplayer docs. 3.9.6. Surround emulation in headphones MPlayer includes an HRTF (Head Related Transfer Function) filter based on an MIT project wherein measurements were taken from microphones mounted on a dummy human head. Although it is not possible to exactly imitate a surround system, MPlayer's HRTF filter does provide more spatially immersive audio in 2-channel headphones. Regular downmixing simply combines all the channels into two; besides combining the channels, hrtf generates subtle echoes, increases the stereo separation slightly, and alters the volume of some frequencies. Whether HRTF sounds better may be dependent on the source audio and a matter of personal taste, but it is definitely worth trying out. To play a DVD with HRTF: mplayer dvd://1 -channels 6 -af hrtf hrtf only works well with 5 or 6 channels. Also, hrtf requires 48 kHz audio. DVD audio is already 48 kHz, but if you have a file with a different sampling rate that you want to play using hrtf you must resample it: mplayer filename -channels 6 -af resample=48000,hrtf _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
