You are so good.
I want to tell you that in the multimedia world, computer technology has been able to simulate the sound of the real world, the image and the dynamic effect of many real world.
Using VRML virtual reality technology, combined with sound stereochemical, computer interaction, and 3D modeling, C Builder programming is made. A virtual audio-visual chamber can be established, and users can experience almost real live music in various playback patterns in the works to achieve the interaction of players and music worlds.
How do you achieve three-dimensional sound effects in a virtual scene?
The sound in the virtual world, wants to give real feelings, this is to require sound stereo, generate 3D sound effects. In other words, when he heard a voice in the virtual world, it is possible to clearly determine what direction spread from, and can feel the distance from the sound source of the sound according to the sound intensity. And the probably position of the sound source, etc.
In reality, the sound heard by the two ears of people is subtle according to the position of the sound source, because the time and frequency of the acoustic wave spread in the medium, the human brain is subjected to this subtle Differences are determined, the sound in the real world. However, for high frequency sounds, it is difficult to determine the difference in time, so this must be judged by the frequency difference between the two ears. When the sound wave reaches the left ear from the right ear, the head is slightly reduced, so that the sound frequency of the left ear is changed, according to this difference, we can determine the position of the sound source.
The sound stereo is based on the scene, regenerating the differences in the time and frequency of these arrivals, so that we can hear the true three-dimensional sound effect. Sound stereo is a digital signal processing process, after processing, so that the sound seems to be issued from a specific point of the three-dimensional space, there is a specific sound source. However, this sound is not fixed in the three-dimensional space, as in the real world, can also be changed according to the needs of the scene, or the sound can be surrounded by side.
So as long as we change the position of the sound source point, change the sound of the sound source point, even let the sound source point move, then you can simulate the various listening environments in reality, create a variety of different music atmosphere, let The audience integrates into our virtual sound world, truly realizes the interaction of music appreciation, which is the purpose we have to achieve.
Establish a variety of virtual listening modes based on the needs of the music. You can let players appreciate the home theater, the flashing stage, and return to natural and colorful listening fun.
So what is the characteristic of virtual listening mode?
First, music is not just the world of sound, it needs to move, the environment is interpreted. People always like to concert listening to live music, because many ways, multi-angle appreciate music, is really enjoying music. Our work is to simulate this sound effect, which makes people feel the virtual reality. Second, in each listening mode, players can achieve various actions such as running, walking, and turning around the mouse. In the virtual world, the player has changed in the direction of the audio source point, so there is a change in the auditory effect. Third, in order to meet the requirements of picky users, in the advanced settings, we can make the player to set the location of the sound source, the number of sound sources, the direction of communication, and the various properties such as the number of players, adapt to different players, achieve different listening Tone effect.
Finally, I want to emphasize the function of the general music player, such as: display playback time, play the next song, save the playlist, and so on. But my purpose is not a general music player. We are already young people in the new century. The general passive music player can no longer meet our requirements, we need to innovate, I believe that my player itself is an innovation, it can make music enthusiasts It is a non-average music journey to experience a non-average music journey, which is personally involved in the music, and no longer passively accepted. Also, our work has a powerful vitality, the virtual reality itself is an important research direction in the world, and our research is to lead the multimedia to the virtual world and go to three-dimensional space. If we combine our design with Java technology, our work can be on the Internet, use it on the Internet; if we have a certain assist, we can even make a virtual cinema.
