Description
Technical Field
The invention belongs to the technical field of echo reverberation, and particularly relates to a visual curve interface system of echo reverberation effect parameters.
Background
Reverberation refers to the reflection of sound waves by obstacles such as walls in a room, so that in the same physical space, sound sources reach human ears, and besides direct sound directly transmitted, reflected waves reaching human ears after passing through a plurality of reflection paths. Echo means that sound waves are reflected at interfaces when they strike large reflecting surfaces (such as walls of buildings, inside mountains, etc.) during propagation, and people distinguish the reflected sound waves from the original sound waves.
Sound waves generated by sound can propagate in every direction and every corner, and among these sound waves, some can reach the microphone directly or be transmitted directly to our ears, and we call such sound as direct sound. Sound waves other than direct sound collide with everywhere we see, such as furniture, floors, ceilings, walls, etc., and when the sound waves collide with the surfaces of the objects, some of the sound waves are reflected by the surfaces of the objects and are re-emitted with some of the sound waves being reflected and re-returned to the room, and some of the sound waves are absorbed. Because the sound wave needs to take a certain time in the propagation process, the direct sound arrives earlier than the reflected sound. It is worth mentioning that if the reflected sound of the sound is recovered again, a very short delay will occur. Reverberation and echo belong to reflected sounds.
The visualized curve interface of the echo reverberation effect parameter is an interface for carrying out real-time visualized display on the echo reverberation parameter and the echo reverberation effect, and can reflect the real-time echo reverberation parameter, the echo reverberation state and the echo reverberation effect.
