Description of the Invention: [Technical Field] The present invention is an embedded high-speed audio conversion device, which is a device capable of extracting digital music from a music optical disc at high speed and directly converting it into various digital encoding formats. .曰[Prior technology] In recent years, the digital code technology has flourished, and the sound quality of digital coded music has gradually caught up with the traditional sound and sound. The technical breakthrough of the game has made the music player of the Wei digital code format gradually become The domain model on the market; although the thief digital coded phonograph has become quite popular', but the source of digital coded music is still nothing more than downloaded by the Internet or converted by music CD; fine, by the township_Minlin The silk (10) code music will be taken off, so the green that is touched by the music handle and converted into digital coded music is still the bulk of today's digital coded music sources. *The voice conversion method of the 'skills' is implemented by a computer through a software for voice conversion, and also by a voice conversion device; since the former is a voice conversion on a computer through a software, the user is interested in the operation. To the people « «财, money slave voice transfer body, began to perform voice conversion to obtain digital coded music, but because of the software set hand ^ complex 'often brought to the cap often frenzied and inconvenient, causing the editor to deter And by using the light side to pick up the sound, just remove the sound 帛, Saki through a (two) = early reading music conversion button encoding format: although the process of voice conversion - for the sake of the world to wear chest (10) The domain of the towel from the township from the micro-control shore ontrol Unit' MCU), X86 microprocessor and dirty (five) jobs (four) listening to the architecture processor, plus, the mining (four) coding _ also miscellaneous execution - double speed 200826060 code conversion 'It is also impossible for users to update the secret of faster encoding speed, so the speed of voice conversion is not a good one. If the music is not digitally encoded by A-Ming County, it takes a lot of time, so it takes a lot of time. Xu Inconvenience. In order to solve the shortcomings of the slow conversion speed of the conventional audio conversion, the US Patent Publication No. 2006/Cai Zem specializes in the development of a neo-audio conversion device with a commissioning material, which first reads the digital music of the music CD. Then the digital music machine is digitally encoded music in wav format, and then converted into various digital encoding formats according to the use of face selection, such as _ format, wma format or AAC format; however, since the invention firstly music on the music CD Converting to Rich format and then converting to other formats will still waste time in the voice conversion process. Therefore, in order to solve the above problems, the present invention provides an embedded high-speed audio conversion device with a digital signal processor (called Signal Processing, DSP) as a central processing unit and a high-speed coding firmware, and uses the digital music scarf to digitize The music is directly converted into digitally encoded music 'to reduce the complicated process of sound conversion and improve the efficiency of voice conversion to reduce the time of voice conversion' and at the same time solve the problem that the conventional voice conversion device cannot update the moving body, and improve the convenience of the body update. SUMMARY OF THE INVENTION The main object of the present invention is to provide a high-speed sound conversion device for viewing people, which improves the efficiency of voice conversion by a digital signal processor and a high-speed coded firmware in the voice conversion device, thereby saving the time of voice conversion. . Another object of the present invention is to provide an in-vehicle high-speed audio conversion device, which is capable of simplifying firmware update by reading a device with a _update program age or a memory card (10) by digit processing 6 200826060 signal processing n The program. Still another object of the present invention is to enable a user to input a sound through a microphone through an analog digital converter and convert it into digitally encoded music via a digital signal processor to improve the convenience of digital recording. In order to achieve the above object, the present invention provides an in-vehicle type high-speed audio conversion device, which comprises an optical disc system (10) for reading a music disc at a double speed and taking out digital music, and the digital music is edited by a central processing single reading. To encode the music, and to access the interface, live on the f-ship, and the towel processing unit is connected to at least the (four) module to store the bedding, the user-operated user interface - use the continuation or output audio signal «; conversion device' respectively connected to the central processing unit; allowing users to easily and efficiently perform voice conversion and digital recording, and self-promotion of the new embedded high-speed voice transfer Blade body. The purpose, technical content, features and effects achieved by the present invention will be more readily understood by the detailed description of the specific embodiments. [Embodiment] The present invention is to solve the problem that the operation of the voice conversion process is complicated by the software, resulting in inconvenience in operation, and the low conversion efficiency of the sound transfer and the inability to be new.
