Embodiment Construction

[0012] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the examples, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below.

[0013] In some situations in daily life, such as the audio of movies or games, it is often necessary to play some sounds so that people feel that they are coming from a certain direction. For example: in a certain movie, it is necessary to make a dog bark from a 45-degree right front and a distance of 3 meters, then we can add the collected dog barking sound to this location information (45 degrees right front, 3 meters away) for Unicode. A kind of speech coding method that carries location information provided by the present invention, specifically comprises the following steps:

[0014] (1), signal acquisition step: collect voice signal through the receiver, and fo...

Abstract

The invention relates to the language coding technology, especially a voice coding method carrying position information. The method comprises: a signal obtaining step of collecting voice signals through a receiver, and forming position information through a sensor or manual input mode; a transcoding step of transforming the voice signals into voice digit signals from voice analog signals through an A/D converter, and converting the position information into binary position information of fixed lengths through a position encoder; and a recoding step of regenerating the binary position information and the voice digit signals into new voice data through a voice synthesizer. The method performs uniformed coding on position information and voice through the steps of signal obtaining, transcoding and recoding, realizes carrying position information in voice information, and can recover surround sound voice frequency according to sound card features, and obtain corresponding voice frequency data carrying position information whether it is a stereo sound card, a 5.1 sound card or a 7.1 sound card.

Description

technical field [0001] The invention relates to language coding technology, in particular to a voice coding method carrying location information. Background technique [0002] At present, the audio data format generally only contains audio information, and does not separately encode the location information of the sound source. An audio file with a 5.1 or 7.1 audio track format that can give people a sense of orientation. However, 5.1 or 7.1 audio files require a multi-channel sound card and multiple speakers to allow people to feel the direction of the sound. At present, virtual 5.1 and virtual 7.1 processing require the original sound to contain 5.1 or 7.1 sound sources, otherwise the surround effect of the sound cannot be reproduced. Contents of the invention [0003] The present invention provides a speech encoding method carrying position information in view of the problems in the prior art, and the sound source orientation information is carried in the audio format...
