Reproduce the auditory effects of various spatial environments and add environmental location information to the sound.

(1) Enhance environmental feelings. Use appropriate reverberation effects to simulate different scenes such as rooms and caves, enhance the audience's immersion in the storyline and environment, and enhance the audience's participation and interest; (2) Improve the sound quality and naturalness of the sound. We use appropriate reverberation processing to add some sense of space to the sound and make the recorded audio more three-dimensional and musical. This can make the human voice or sound effect more full, natural, and appear more real, and reduce the dryness of the sound. Or a flat listening experience; (3) Make up for the environmental problems caused by early recording. Sometimes, the original recording sound field is too small and the sense of space is too poor. Adding appropriate reverberation effects can partially compensate for some recording environment problems, make the audio sound more balanced and coherent, and improve the overall quality.

Reverb: The effect produced by sound reflection in a closed space. Reverb can be used to simulate the listening effects of different environmental spaces.

Note: Your appropriate reverberation will worsen the sense of hearing and should be carefully designed according to the needs of the scene.

(1) Use reverberation to distinguish different vocal forms. Let the audience understand the difference between narrated lines and non-narrated lines, so that the audience can more intuitively distinguish whether this line is spoken by the character or recited silently in the heart, or in a dream;

(2) Use reverberation to distinguish different spatial environments. For example, in a large room, a cave, an empty swimming pool, a large shopping mall, etc., the sound sensation brought by each location is different. We can add different reverberations to the sounds in different spaces and locations. , used to simulate different environments in reality, so that the audience can have a greater sense of immersion and presence. Even in the same space, if we want to make the other party's speech and actions sound far away, we can also add some reverberation to the human voice or sound effects to make the sound sound more distant;

(3) Use reverb to optimize the performance of the material. For example, in some close-ups of transitions, where the protagonist suddenly becomes nervous and his heart beats wildly, we need to use reverb to add a little difference to the sound effects and highlight them.

Example reverb plug-in: Pro-R Manufacturer: FabFilter (also known as FabFilter)

(1) Reasons for choosing the FabFilter Pro-R example. It has a modular and visual operation interface, which is suitable for newcomers to get started quickly. At the same time, there are many reverberation plug-ins on the market. After learning the basic parameters, you can choose them according to your own preferences.

(4) Space knob in the center (Adjust the size of the simulated acoustic space environment to achieve the acoustic listening experience of a bathroom or a church. Turn the knob to the left to make it smaller, and to the right to make it larger.)

(5) The Brightness knob on the far left (mainly simulates space materials, adjusts the high-frequency ratio and attenuation speed of reverberation, that is, controls the brightness of the reverberation sound, and makes the timbre of the reverberation sound more bright and light or soft and mellow. Turn to the right , the simulated material is smoother, and absorbs less high frequencies. The more energy is reflected, the brighter the sound material sounds, such as the bathroom wall effect; turn it to the left, and the simulated surface material becomes rougher. For high frequencies The more absorption, the duller the sound material will be, such as quilts, curtains, etc.)

(6) The second Character knob from the left (affects the purity and turbidity of the reverberation). Turn it to the left, and the reverberation will be cleaner. Turn it to the right, and the reverberation will be muddier. To the middle 50% Sometimes, some modulation functions will be added, and more and more modulation functions will be added to the right. In the end, it will have a harmonic-like effect, so the reverberation will become muddier as it moves to the right. Note: This does not mean that the cleaner the reverb, the better. , the muddier it is, the worse it is. It mainly depends on the sense of hearing.)

(7) The third Distance knob from the left (mainly adjusts the sense of distance and space of the reverb, turn it to the left for closer distance, and turn it to the right for farther distance.)

(8) The third Decay Rate knob from the right (controls the speed at which the reverberation decays from the strongest volume to silence. The decay speed slows down and the reverberation time is lengthened. In terms of hearing, the late reverberation tail is more Strong, the room is larger and more spacious. This parameter is used to fine-tune the space. The adjustment of this knob will directly affect the change of the space size.)

(9) The second Stereo Width (sound field width) knob from the right (1. Increasing the Stereo Width will strengthen the three-dimensional sense of the reverberation, and the difference between the left and right channels will become larger, which can give people a wider and more three-dimensional sound. 2. Reduce Stereo Width to reduce the difference between the left and right channels of reverberation, which will result in a single, narrow reverberation space. Generally, when we do sound post-production, the protagonists are often in different places. At this time, we need to build that sense of presence. Don't let all the lines be said in front of us. If we want an immersive sense of presence, we can achieve it through different sound field widths. When this knob is on the far left, it is. Mono, as you move to the right, the sound field will become wider and wider. However, the wider the sound field, the better, because the wider the sound field, the wider the separation between the left and right channels will be. The two voices are one on the left and one on the right, so the clarity of the lines itself will also decrease, so we need to balance the clarity of the lines and the width of the sound field to find a middle value.)

(10) The first Mix (wet-dry ratio) knob from the right (dry sound is the direct sound that has not been processed, and the sound that has been reverberated is the wet sound. This parameter is to adjust the ratio of the superposition of dry and wet sounds. , so as to achieve the reverberation effect we want. But note: when the proportion of wet sound in the reverberation is too large, our sound will become chaotic and unclear. There is only one major premise for any processing we do, and that is to ensure that. The lines are clear, and the appropriate dry-to-wet ratio is the most important thing for us to adjust the reverberation.)
