![]() ![]() In my phone called "Audio System Test." Those are the first 21 songs I enjoy whenever I'm evaluating a new car. Harman International How I test audio systems ![]() When listening to your premium audio system, the left, center and right channels should not sound like they're emanating from speakers, but from these virtual orbs instead. A great audio system projects the illusion that you're at a live performance. The bottom line is that it should never seem as though you're listening to sound coming from speakers. Either way, you should be able to "see" where specific sounds are emanating. Sometimes you're given the option to be immersed on stage or be in the virtual audience, all without having to adjust the fader setting. Other suppliers may leave the sound imaging strictly in front of you. Sometimes an audio supplier will tune its virtual sound stage to envelop you as though you're on stage with the band. In addition to all the items mentioned previously, if you can quickly pinpoint specific instruments' locations across an imaginary soundstage that seems wider than the car's interior, that's a well setup system. If you close your eyes, you should be able to "see" where the vocals are coming from. When spectrally analyzed, a good audio system should return consistent-looking lines at various volumes. Again, leave those sliders alone in their default middle settings, and you'll hear music reproduced in a way that the artist, producer and your premium audio system engineer intended. Sometimes an automaker will get a little fancier and offer you anywhere from a handful to about a dozen control sliders that individually manage the volume of segments within the audible spectrum. Keep those knobs centered at their most neutral (or "zero") setting, and you'll have flat equalization. Occasionally, midrange is adjustable, too. The most common way is via the bass and treble adjustments. You'd be able to hear the instruments mixed in a way in which every musician complements their fellow performers.įlat equalization places all of a song's instruments on a level playing field, that way the vocals, bass guitar or crashing cymbals don't overpower the rest of the instruments into the background of their own on-stage or in-studio performance.Ĭar audio systems offer a couple of different avenues toward adjusting equalization. But that's not how you would enjoy the music if you were at a live performance or in the recording studio. If an engineer were to tune a sound system for treble-heavy equalization, then you, the consumer, would be forced to focus on the music's high-frequency elements like the cymbals. ![]()
