Design by early scattering theory of control room

For how to design the control room, recording of demand is not high, so long as to be able to hear the voice, the so-called "right" to it to complete its work on the line, this is a question of accuracy. This is the most important, of course, you may request it's comfortable, able to work eight hours, and the fresh air, sufficient for the whole band member Ambassador can sit in a room in shrink and concrete, of arbitrary corner listening to sound like the noise better, in the control room in shrink out things, get another Studio, home, car audio to hear all the same, and so on.


Over the years, a variety of efforts to control room is a real voice, but in fact not true, because you listen to anything or depend on the listening environment. To this end, room designer for this invention many tips, eventually became early acoustic scattering solution.

Concentration of history--control room design

1960s, dry sound room (DeadRoom)

At that time, most music is rock music, producer requires direct sound heard that other not very bad, the finished product, the recording time can only work for 20 minutes, the whole room no short reverb, the human ear can not afford. May not be so bad that an overall impression.

The 70 's

Then have a stereo, people began to pay attention to the design of the control room, the best control room-step full wall with rough stone, speakers embedded in the wall, wall and ceiling made of bevel prevent echo. Hard wall provides sound reflection, produces acoustic perspective, it sounds no longer like put your head into the hair to do box, the General decay time, 100 m to 200 m to 380mg, 430mg, but no two rooms sounds like, a room and two local also sounds different.

Experienced sound recording engineer on the amplifier before, so that both Heng sound spectrum analyzer that look the same, but still does not resolve the problem.

The 80 's:

LEDE and lighting control

Mr. LEDE (LiveEndDeadEnd) first off the popularity in the 1980s, the United States were in the control room DonDavis step surface area of almost no reaction. His design enables direct access to sound and reflections of the time difference is long enough for the first time, the human brain can feel the room acoustic reflection, and can be ignored, this can be restored in the control room listening environments, and in the same LEDE control room to hear things are the same, in order to make the recording more comfortable to work, back wall or hard materials, but not cause slap. The theory that scattering MwfredSchroeder no Echo (ECHO), but there are some short reflex Decay.


Using short delay produced by the environmental effects before

The 60 's, 70 's wet reverb effect today is not too much. 1980s to low chorus, the 1990s were very clear sound localization. Recording with less reverb, listen to point the red pepper.

Only with a dry sound without reverb can have that kind of effect, but our musical instruments in an environmental performance, musical instrument itself. If you do, the lack of natural and suction line. Old like a drum machine, clean but no vitality, synthesizer and sampler instrument is the same, but if you joined the reverberation, makes sound distance to farther, do to make the recording sounds very real, and winds coming?

Some recording with speakers play the sound, electronic musical instruments and microphones to pick up, not as a method, but the better approach, with a short delay to create this kind of "room microphone".

Sound models, an electronic reverb for RI is a variety of room sound reflection of felt-, first in small, hard, sound-absorbing dry room recorded the sound of the "face" of the early people use digital delay, the delay time is set to 1, mixing these-10mg delayed sound to create a "comb wave" effect. With today's effects, reverb with reflection instead of long decay. Instead of a short delay.

Many effects provides a short Delay skills, multitone heavy chorus algorithm. Many cheap multiple effects to a stereo input signal into Mono, long delayed by lntialDelayFeedbacklevelpan to control, multi-tone modulation of Chorus can also Delay the total human time or each delay code.

Note:

This created a small, flat room effect

Very full modulation (Modulaton) join the dynamic of angry

If you want more static sound, the depth in ooo,

To change the properties of a room. Adjusting the predelay time (005, 007, 010). The next preset operation with the Tapped Midiverb4, although it only three Tap, as four tone chorus, each more flexible.

A short delay in sound and image in the middle of the long sides. If you adjust to obtain additional processing signals, be careful with phase offset, listen to Mono determine sound and correct.

This method may cause the stereo field gets smaller, but I think this is worth it for the drum's overall sound field of the environment.
