An interesting technique to give your vocals more depth and modulation, is to apply the reverse reverb effect and layer it with your main vocal line. This effect is used to create an impact on a particular phrase or word, giving more emphasis to the emotions attached.
Reverb is one of the most essential elements in your toolkit because it can add depth to a track, while making space for instruments. Reverberation or reverb effect is created when a sound is reflected back to the listener’s ears from surrounding objects. These could include furniture, people and air. The reflected signal causes a large number of reflections to build up and subsequently decay, as the sound gets absorbed by the objects/surfaces in the space.
Fx or effects help to create the essential movements in your track. They can include any recorded or synthesized sounds used as supportive elements to make smoother transitions from one part to another. The effect shown in the video is that of a Reversed Reverb Fx that can increase the spatial feel within your tracks.
