Sound Effects

Sound is refers to the sounds made by effect, it is to point to to enhance realism, the atmosphere of a scene or drama messages and add to the murmur of the vocal cords or voice. The voice of the so-called included the music and sound. Include the digital sound, environmental sound, MP3 audio (common sound, professional sound).

Digital sound

Digital sound "EQ mode, namely the MP3 playback, the voice of the different different EQ mode to listen to the voice of the different users play effect, and EQ mode is also the most outstanding individual character of place, to the user to bring more music enjoyment.

The current MP3 digital sound models often for six, and points and is CLASSIC music (classical mode), POP, POP music mode), (JAZZ (JAZZ mode), (ROCK music mode),'m NOMAL (normal mode) and AUTO (automatically change the mode). Of course in the choose and buy is not a digital generation MP3 audio mode the more the better, do it for the best practical.

Environment sound

The main means to pass the digital sound processor to voice processing, make the voice sounds with different space characteristics, such as the hall, opera, theater, cave, stadium, etc. Environmental sound mainly through the sound to the environment of filter, environment, the environment, the environment reflected displacement of the transition, processing, make the listening who feel as if place oneself in different environment. This sound processing in computer application is very common, sound card now in the application of the combined sound also gradually rise more. Environmental sound also have its drawback, because of sound processing inevitably lose some sound information, and now can simulate the effect and the real environment still lag behind, so someone will feel sound "false".

MP3 audio: ordinary sound

How to use the equalizer to get better sound performance, is every MP3 required for all the lovers.

Different MP3 players set equalizer is endless also and same, such as IRIVER IAUDIO and the equalizer though are divided into levels, but the frequency division and adjust the level also each are not identical, IRIVER XtremeEQ divided into five sections: 50 Hz ac 200 Hz ac shift, and shift, and 1 KHz files, 3 KHz files, 14 KHz file, each section has 10 levels adjustment:-15 dB,-12 dB,-9 dB, 6 dB-and 3 dB, 0 dB, + 3 dB, + 6 dB, + 9 dB, + 12 dB + 15 dB,. And the IAUDIO is divided into 60 Hz ac 250 Hz ac shift, and shift, and 1 KHz files, 4 KHz files, 12 KHz file, each section has + 0 db ~ + 12 db12 level can be adjusted. Contrast visible, although frequency division is not the same, but also very much the same, adjust to sound plays a similar role. Here's a look at after block equalizer every part of the role:

1. 20 Hz ac-60 Hz ac parts

This period of ascension can give music strong feeling, give a person very loud feeling, such as the thunder. Music is strong in feeling, if the frequency band of feeling too little, it must not feel smooth; And will cause a high frequency and high frequency of the outstanding, makes voice lost balance, not durable listen. If ascension is too high, and will be cloudy, poor definition clear cause, especially low frequency response sent and low frequency overweight stereo equipment.

2. 60 Hz ac-250 Hz ac parts

This paragraph is music low frequency structure, they contain the rhythm section, including the basis of pitch and rhythm sound sound of the tonic. It and the proportion of high school sound constitutes the structure tone of balance characteristics. Ascension this a can make the voice plump, excessive ascension will have a rumbling sound. These two paragraphs will make attenuation thin voice.

3. 250 Hz ac-2 KHz parts

This section contains the most Musical Instruments of low frequency harmonics, if ascension will make sound like too much the voice on the phone. Such as the 600 Hz ac and 1 kHz excessive ascension can make sound like a trumpet sound. Such as the 3 kHz ascending too much can speak the identification of the sound, masking is slurred, and make lip phone "MBV" is difficult to recognize. Such as 1 kHz and 3 kHz too ascension can make sound with metal feeling. Due to the human ear a frequency band is more sensitive, usually don't adjust this a, too much will make this a improve listening fatigue.

4. 2 KHz-4 KHz parts

This period of frequency of intermediate frequency, too high if ascension will hide talk of the recognition, especially 3 kHz sound too high, it will cause improve listening fatigue.

5. 4 kHz-5 kHz parts

This is a telepresence band, it influences the language and the clarity of the voice of the instruments. Improve the frequency band, make the person feels sound sources and the listener's distance is a bit close some; Attenuation 5 kHz, can make the distance change far; the voice If in five kHz put forward 6 dB/around, it will make the whole mix of voice sound power ascension 3 dB.

6. 6 kHz-16 kHz parts

The frequency control the brightness of tone, a degree and clarity. Generally improve the segments that has a loud voice, but not clear, not may cause ChiYin sound when overweight, attenuation becomes clear, but has a loud voice.

The equalizer can also accordance with listening to the limits of door to set the graph, let the ear can the most easy to feel the most natural voice, so the best!!!!!

So let the low and high frequency can naturally be ears feel, that is the best EQ Settings and the graph should coincide.

In the adjustment of equalizer is best can on the ring curve and the frequency response curve. For example, if the frequency response curve is the ideal, also is a straight line, can be so will adjust the equalizer for and corresponding level of similar under such as curve graphics, so the sound of each frequency band level is basically is in balance; And the fact that no headphones/earplugs frequency response curve is ideal straight, and still be everyone's ears wearing different impact, so to adjust good equalizer is over a period of time to figure out master player and headphone in your ears to hear the voice of their respective up properties.

Finally still need explanation: each person feeling of the voice of different frequency is not the same, audio playback equipment frequency response is different also, people listen to the door of the curve also is according to statistics draw others sounds very natural voice you may feel uncomfortable, so the adjustment of the equalizer according to their own needs to sense the use of characteristics and play equipment of personalized adjustment.
