Six Techniques for Creating A Three-dimensional Sound

- Sep 05, 2018-

1. Use compression to highlight a certain track

When some very important sounds, especially vocals, become very confusing, you should add some compression. Adding a compressed track will sound more pronounced than if it weren't added, because quieter notes or syllables are raised near the peak, so these details are not obscured in a louder sound background. And the volume of the track to which the compression effect is added does not increase too much.

But note: when using compression, very little compression is sufficient. Too much compression will make the sound plastic and awkward. Be sure to listen to this track on a different speaker (monitor) system after using compression, so you can know if the compression is too much or not enough.

2. Increase the distance of the microphone to bring depth to the sound

Of course, you can put the microphone in the same position forever when recording, but this will cause all the sounds to sound from the same distance. Try moving the microphone backwards to add depth to the sound. In the mix, the sound recorded by placing the microphone in a farther position sounds farther, as if the background sound was emitted behind the human voice. This is a trick to create a play band in the room.

Note: Recording the microphone backwards at a certain distance does increase the sense of space in the recording, but it is necessary to record in an acoustically sound room and ensure that other sources are isolated. It should also be prepared for some of the remaining high frequency details. This technique is usually used on the drum and percussion tracks, but if the microphone leaves a certain distance to pick up the drum or percussion, the room must be sound-absorbing, there must not be too many hard surfaces, and otherwise it will produce a knock. The echo and harsh bands are prominent.

3. Adjust the balance to make the sound more dynamic

Mixing can make the track layered, creating a feeling that the instrument or singer moves in the virtual space. Most people do this by using stereo phase adjustment, but by adjusting both low and high frequency equalization, you can also create a feeling of sound movement. After all, in the real world, if the sources are moved, their frequencies will change.

4. Use a retro microphone to bring artistic effects to the sound

Using an excellent microphone, or an old classic microphone for recording, the effect is hard to imitate even with more digital devices. Using a retro microphone will make your recorded sound sound like a tube passing from another area. This will make the recorded sound more interesting and build a general aesthetic.

5. Adjust the energy of the sound through the "dry and wet" adjustment

In the process of mixing, the effects affect each other: compression, noise reduction, reverberation, and equalization produce overlays in the mix. These steps are part of a professional recording, and each step is done according to its own rules. But there is a universal rule. When a song sounds problematic, turn off all the effects and return the track to the "dry" state. This action changes the energy and intensity of the sound, and this may be exactly what you want.

Mixing in the DAW (digital audio workstation), we have a lot of initiative in editing and changing the effect. But to use it properly, don't make major changes and adjustments.

6. Adjusting speed and pitch produces psychedelic effects

The characters in science fiction can shuttle through the space of different speeds. In the mix, this technique can also be achieved by adjusting the speed and pitch. This is a technique used in the period of using a four-track cassette recording device. Most four-track recording devices have a speed-adjustable turntable. When recording a large drum track, you need to turn the speed up a bit (and play faster) and then reverse it at normal speed. Nowadays, on digital recording platforms, you can also use these techniques in terms of speed and pitch. For example, you can lower the speed of a track without lowering its pitch, and vice versa.

These techniques can produce psychedelic sound effects, especially when recording on drums and guitar tracks. But be careful not to increase the speed of the vocals. In the process of adjustment, step by step to get the perfect effect. Sometimes it's good to "drag" when mixing, as long as you can call out the voices that the listeners enjoy.
