Tips Assessing the Quality of Audio Systems. Well in this article. I'll try to explain "how-to" her. Hopefully pretty easy to follow and can be done in a relatively short time - 15-30 minutes is enough.
Tonal Accuracy and Spectral Balance
To assess these two characters, you have two choices. The first is if you have been accustomed to listening to the sound of musical instruments directly, the second is if you rarely listen to the sound of the instrument directly.
If you frequently listen to the sound of live instruments, then you can use the songs are available on CD IASCA. CD has been designed in such a way that the songs are songs recorded in it is very natural (of course with a low royalty fee as well). Just follow the instructions in the CD booklet - and you are ready to go.
But if you rarely listen to the live sound, then you can use the CD Focal JMLab, Demo CD 2, or often called Focal / JMLab Tools CD. In the CD, but there are songs of choice, there are also voices that often we encounter daily, such as engine noise, the sound of a pencil, the sound of glass breaking and so on.
If you do not have the second CD, then you can also use the CD that has audiophile quality. Just because the CD-CD is a lot that has no guarantees natural sound, then you are the man of his vocal sound.
Choose a song sung by a female high voice, low voice of women, men of high and low voice.
Notice how the human voice it? Does it sound natural (you would often hear someone you talk anyway?), Or does it sound like a robot voice, the voice of the cans, the sound of a closed mouth tissue? A good audio system will play a human vocal sounds such as if the vocalist is in the same room with us.
Do not forget, when listened to the song, you are strongly encouraged to sit in proper position. If you're assessing the home audio system, then you have to sit right down left and right speakers. If you judge a car audio system, then you have to sit in the driver's seat.
