but the voices sound like they are right there in front of me. and the other speaker is about 7ft away from me. With time-alignment, i have one front speaker that is about 4ft away from me. you might want to try and use it a little bit just to test/experiment.Ĭhances are you will have better results. It will probably get in the way when you are trying to walk.ģD effects are supposed to touch your soul when they happen.Īnd its always a better thing to have, because if you dont think you are gonna use it. if one set of speakers was a little bit late, you would have to move them back away from the listening position - or you would have to move all of the other speakers closer.Īnd this can be annoying if you have to move a speaker 4ft closer to your ears. the speakers are all different and they might project the audio at different speeds. that means no differences of 3-5 inches.īut even then. There really isnt any 'in your face' 3D special effects without calibrating the speakers with time-alignment unless all of the speakers are exactly the same distance away from your ears.Īnd when i say exactly. but the 3D effect is so close and in your face that your brain will think it can grab it. the sound of the car will simply go from the left speaker to the right speaker.Īnd it will make a stop at the center channel along the way.īut if you have time-alignment, the sound goes from the left speaker to the right speaker. There are times when the audio gives you a nice big hug and then throws half of your brain off for a ride.Īn example of this would be a car driving by. The only way to know the difference is to have experienced it yourself.īut if i had to describe it to you, it would be best said as the ability to hear special 3D effects. the sound processor will delay the output of the speaker that is closest to you so that both soundwaves reach your ears at the same exact time. no matter how hard you try to adjust the volume so that the speakers sound equally far apart - the audio from the speaker that is 3ft away will always reach your ears before the speaker that is 10ft away. If you have one speaker that is 3ft away from you, and the other speaker is 10ft away from you. The beautiful thing about time-alignment is pretty clear.
You can get ALMOST the same results by adjusting the volume seperately for each speaker, but there are more important things like actual delay and the ability for the speaker to pass along its audio through the air without creating congestion with the other speakers. having an equalizer is a must if you plan on calibrating the frequency response with a calibration microphone.īut something that might be overlooked is time-alignment.īeing able to calibrate the distance of the speaker from the listening position is always a must have.
However, there are some important features that i am willing to help you decide on.įor example. I would simply tell you to buy one from a store that will allow you to return it for a ful refund if you are not satisfied. anything with a headphone jack will help you make that determination.Īs far as soundcards go.
#Best external sound card for movies portable
You can use an ipod or portable cd player or an old portable cassette player. but maybe one of the sets of speakers has died and caused damage to the soundcard, and now the soundcard is passing along that damage to the remaining speakers. The first thing i would do is connect each set of speakers to something different and make sure they all still work. Knowing that the speakers have a dedicated amplifier helped tremendously.
