随着音响设备的不断更新,系统的不断完善,现在几乎每一套音响系统都缺少不了混响器这一周边设备。济南音响的混响效果可以使声音变的更真实、饱满而不干涩,尤其在人声的处理时,几乎不可缺少。但是混响等音频效果的添加与处理,一定要适可而止、宁缺勿滥,加的不到位,还可以继续添加或通过其他处理来弥补,一旦加的过多,你的音乐将变的一团浑沌严重影响声音的清晰度和理解度,因此如何能充分的利用,更好的利用就是我们要探讨的问题。以卜是我们常用的几个混响调试参数。
With the continuous improvement of the audio equipment, the system is constantly improved, and now almost every sound system is lack of the peripheral equipment. Jinan sound reverberation effects can make the sound more true and full and not dry, especially in the processing of the vocal, almost indispensable. But add reverberation audio effects and handling, be sure to moderation, Ningquewulan and does not reach the designated position, you can also continue to add or by other treatment to make up for, once add too much, your music will become a chaos serious influence on sound clarity and understanding. Therefore, how to fully use and make better use of is what we are going to discuss the problem. In order not to be used in some of the parameters of the reverberation test.
混响的定义:室内声源停止发声后,由于房间边界面或其中障碍物使声波多次反射或散射而产生声音延续的现象。声波在室内传播时,要被墙蹄、天花板、地板等障碍物反射,每反射一次都要被障碍物吸收一些。这样,当声源停停止发声后,声波在室内要经过多次反射和吸收,最后才消失,我们就感觉到声源停止发声后声音还继续一段时间.这种现象叫做混响,这段时间叫做混响时间.
The definition of reverberation: the phenomenon that the sound source of the room is stopped, because of the sound of the room or in which the obstacle is made to generate a sound, a sound that is reflected or scattered. When the sound waves in the interior, to be wall, ceiling, floor, and other obstacles to reflection, each reflection is to be an obstacle to absorb some of the. In this way, when the sound source to stop the sound, the sound in the room to go through several times of reflection and absorption, and finally disappeared, we feel that the sound source to stop the sound after a period of time.
混响时间(reverbdme):表示声音混响程度的参数量,当室内声场达到稳态,声源停止发声后,声压级降低60dB所需要的时间称为混响时间,记作T60或RT,单位是秒(s)。混响时间是目前音质设计中能定量估算的重要评价指标。,占直接影响厅堂音质的效果。
Reverberation time (reverbdme): the amount of parameters of sound reverberation level, when the indoor sound field reaches the steady state, the sound source stops the sound, and the sound pressure level of the sound pressure level is called the reverberation time, T60 or RT, the unit is 60dB (s). Reverberation time is an important evaluation index for quantitative evaluation of the quality of the sound. For, directly affect the sound quality.
预延时(predelay);房间中产生的第?组反射声或混响声开始之前的时间。一个较长的预延时时间将给你一种非常巨大的声学空间的感觉。
Pre delay (predelay); the time of the formation of a third set of reflections or reverberation in the room. A long delay time will give you a feeling of a very large acoustic space.
衰减时间(decaytime):调整混响声的尾部衰减到听不到时所经过的时间。
Time (decaytime): adjust the tail of the mixed noise to hear the time passed by.
早反射的散射度(Earlyreflectionsdiffusion):影响混响部分反射声密度的一个参数值。指反射声的无规律程度,空间的形状越不规则,声音的散射度就越大,反射声越多,相耳之间越接近,混响是连声一片的,声音很温和:反之空间的形状越规则,反射声的出现越有规律,声音的散射度就越小,反射声越少,相互之间隔得越开,混响声听起来就比较接近回声了,声音很清晰。
The scattering degree (Earlyreflectionsdiffusion) of the early reflection (): a parameter that affects the acoustic density of a reverberation part. Refers to the reflection of sound. No regularity, spatial shape is irregular, the scattering of sound more, reflected sound more, between the lugs closer, reverberation is the repeatedly a piece, the sound is very mild: instead of space shape, the more rules and reflected sound more regularly, the scattering of sound more small, less acoustic reflex, between each other, the more open, the reverberation sound is close to echo the, the sound is very clear.
济南音响 http://www.jnzqyx.com/ 以上几个参数的调整,我们就基本上可以模拟出任何环境的任何混响效果。 在使用中,大体可以把混响效果分为修饰用混响、模拟环境用混响和渲染气氛用混响。
Ji'nan sound more than a few parameters of the adjustment, we basically can simulate any of the environment any reverberation effect. In the use, the reverberation effect can be divided into the reverberation, the simulated environment and the atmosphere of the rendering.
修饰用混响顾名思义就是修饰声音的一种混响,每一种表演形式都需要不同的混响效果,但对于任何唱腔,预延时(predelay)的调整我只遵循?个原则,就是每一段曲子,数四个八拍,算出每个拍子的时间,预延时的时间就是这一个拍子的四分之一时间,这样做的好处就是可以更好的修饰歌者的声音,而不会影响到声音的清晰度以及使前一个音的混响影响到后一个音。
Modified by the reverberation is a name for a modified sound a reverberation, each a form of performing need different reverberation effect, but for any singing, pre delay (predelay) to adjust I follow? Principle is every song, four eight shot, calculated for each beat time, quarter of the time of pre delay time is this a beat, the benefits of doing so is better modification of the singer's voice, and will not affect the sound clarity and before a sound reverberation effects to a sound.
 乐器在预延时和混响时间的调节上都可以效仿以上办法,不过预延时时间应该是?个拍子的八分之一,散射度的调节上也有所区别,例如,低密度的散射值对于打击乐的声音就会出现问题,这是由于第一声反射声更象离散的回声,而不是混响声。提高散射值可以解决这一问题。然而,低密度的散射值可以与人声很好地进行配合,使得声音更加丰满,圆润。
Instruments on the regulation of pre delay and reverberation time can follow the above approach, but pre delay time should be one eighth of a beat, scattering of regulation also has the difference, for example, the scattering of low density value for the sound of percussion will be problems, this is due to the first sound reflection sound more like discrete echo, rather than the reverberation sound. Increase the scatter values can solve this problem. However, the low density of the scattered values can be well matched with the human voice, making the sound more plump, mellow.
模拟环境用混响一般使用在剧目演出的某一个特定的场景。在预延时的调节上就需要计算现实中此环境里的一个点声源发出的一个脉冲声波,从最近的一个大的反射面反射回来所需要的时间。譬如此声源处于一个教堂的中间,离最近的大的反射面是墙壁,中间距离是10米,以声波速度340mis计,那么第一次反射声的时间就是在58ms,这也就是预延时的时间,一般教堂的混响时间都比较长,在2s~8s之间,混响时间根据实际情况而定。散射度值设胃得越低,还原出来的空间感也会越大。
A specific scenario for the use of a reverberation in a play. In the regulation of the pre - delay, a sound source is needed to calculate the sound source of a point in the environment, and the time required for the most recent reflection of a large reflective surface. Such as sound source in a church in the middle, from the recent large reflector is walls, middle distance is 10 meters, in terms of acoustic velocity 340mis, so at the time of the first acoustic reflex is in 58ms. This is also the time of pre delay, the reverberation time of the church in general are relatively long, between the 2s~8s, reverberation time according to the actual situation and fixed. The lower the degree of scatter, the lower the value of the stomach, and the more space it is restored.
渲染气氛用混响在演出中不属于常用混响效果。是为了让演员在特定情节表达的情绪能感染观众,是比较抽象的。在使用上分两种情况。
The rendering atmosphere is not commonly used in the performance of the reverberation. Is to let the actors in the specific circumstances of the emotional expression of the audience, is more abstract. In two cases.
一:表达一种歇斯底里的呐喊,宣泄一种凄惨的情绪。这一类混响一般预延时和混响时间都比较长,散射度也比较低,使反射声更像是离散的回声,预延时一般设置在300ms以上,混响时间设置在5s以上,散射度设置以山川的感觉为主,尽量模拟出一个非常空旷的空间,让声音能不停地回荡。
A: expression of a hysterical cry, vent a melancholy mood. This kind of reverberation generally pre delay and reverberation time are relatively long, the scatter is relatively low, so that the reflection sound more like a discrete echo, the pre delay generally set at 300ms above, the reverberation time is set at 5S above, the scattering degree is set to the feeling of mountains and rivers, try to simulate a very open space, so that the sound can not stop.
二:表达一种感叹或者说是豪迈的情绪,使用在朗诵等表演形式中。这?类混响预延时正常语速字间隔时间的四分之一,混响时间以教堂为例,一般设胃在4~6s,散射度不宜过低,需要声音丰满,而且不能影响其清晰度。
Two: expression of a sigh or a heroic mood, used in recitation performances. This normal speed of word class reverberation pre delay interval quarter, reverberation time in church, for example, generally located in the stomach 4~6s, scattering intensity should not be too low, need full sound, but does not affect its clarity.
混响调节需要了解的是设备上各个旋钮和按键的作用是什么,然后再根据实际需要才能调节出让自己和观众都能满意的效果。以上为个人在演出中总结的一点对于混响设置的一点经验,在此与大家共同探讨,不足之处敬请谅解。
Reverberation adjustment need to understand the role of the various buttons and buttons on the device, and then according to the actual need to adjust the transfer of their own and the audience can be satisfied with the effect. The above for the individual in the performance of the summary of the experience of a bit of a set of reverberation, in this with you to explore, the lack of understanding.
