Abstract

The surround-type live stereo method of the present invention is used to realize the multi-sound source positioning effect through the software algorithm of the Java plug-in, comprising: step 1: the live broadcast server receives the source sound signal through the audio input device; step 2: the live broadcast server calls the Java plug-in, to convert the source sound signal into a stereo signal; step 3: the Java plug-in extracts the azimuth, height and frequency of the source sound signal; step 4: the Java plug-in calculates the user's left ear and right ear respectively according to the azimuth, height and frequency of the source sound signal The orientation, height and frequency of the perceived audio signal, and the left and right audio signals are synthesized according to the orientation, height and frequency of the audio signal perceived by the left ear and the right ear; Step 5: the audio output device of the live server outputs the left audio respectively signal and right audio signal. The present invention collects and calculates the sound only by calling the Java plug-in through the live broadcast server, and can output the surround sound only through the software algorithm, and the sound collection is simple.

Description

technical field [0001] The invention relates to stereophonic technology, in particular to a surround-type stereophonic technology. Background technique [0002] Monophonic sound lacks localization of sound, while stereophonic technology has completely changed this situation. The sound was split into two separate channels during the recording, resulting in great sound localization. This technology is widely used in music appreciation, through the sound card that supports the Sound Blaster Pro audio standard to play stereo, so that listeners can clearly distinguish the orientation of each instrument, so that the music is more imaginative and can make the listeners feel The feeling of being there. [0003] At present, for stereo equipment on the market, sound collection requires multiple devices to sequentially transmit sound signals. The sound collection steps are cumbersome and the sound storage cost is high. Moreover, all rely on hardware and placement to achieve surround...
