Embodiment Construction
[0011] 3D phantom sound is the surround sound field of the multi-channel logical positioning system realized by 2.0 two-channel stereo. That is to say, after analyzing the 2.0 two-channel stereo audio file, the technology splits it into multi-channel logical surround sound positioning audio. Then the multi-channel logic surround sound audio files are technically analyzed and merged into 2.0 two-channel stereo audio files, so that people can enjoy the multi-channel logic through ordinary two-channel stereo headphones or 3D phantom audio files played by stereos Position the surround sound field effect.

The invention discloses a three-dimensional (3D) airy sound, and belongs to the technical field of computer music manufacturing. A 2.0 double-sound-track stereo can be changed into a surround field of a dolby logic positioning system, and a 2.0 double-sound-track stereo audio file is analyzed and technically split into multi-sound-track logic surround positioning audios; a multi-sound-track logic surround audio file is technically analyzed and combined to form the 2.0 double-sound-track stereo audio file; and therefore, people can play an audio file through a common double-sound-track stereo headset or a loudspeaker to obtain a multi-sound-track (such as 5.1, 6.1 and 7.1) logic positioning surround field. The 3D airy sound is particularly suitable to be played by a multimedia computer, an automobile loudspeaker, a personal stereo, a family cinema and a cinema and can be applied to a video tape recorder, a laser diode (LD) and video compact disc (VCD) player, a compact disc (CD) player, a limited partnership (LP) juke box, the multimedia computer, a television, a power amplifier and a radio tuner. Interactive and mobile 3D airy sounds can be matched with various playing carriers such as the multimedia computer and an electronic game machine, and interaction surround can be conveniently implemented.
Description
technical field [0001] 3D phantom sound is involved in the field of computer music production technology. Background technique [0002] After entering the era of digital sound, we have experienced several stages of change in audio experience. Audio technology is actually a process of sound restoration. The sound samples collected through recording technology are restored through audio equipment, and the following emerges: Way: [0003] 1. Mono is a relatively original form of sound reproduction. It is to mix audio signals from different directions and record them uniformly with recording equipment, and then replay them by a speaker. The sound field position of this playback method is only in the middle. [0004] 2. Dual-channel is composed of two sound channels. The electrical signals transmitted by them on the circuit are the same, so the sound from the two channels is also the same. The sound field position of this playback mode is only in the middle . [0005] 3. Ste...
