Description

1231913 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a recording technique, and particularly to a method for recording continuous sound data. [Prior art] The conventional recording technology uses a computer system to record continuous sound data (such as analog audio signals). The computer system needs to allocate some memory as a buffer recording area 10 (as shown in Figure 1). (Shown), the buffer recording area 10 has at least one data field 100 and a status field 102, wherein the data field 100 is used to store the data after the computer system samples the continuous sound data. The status field 10 2 is used to store the current usage status of the buffered recording area 10. If the usage status is a processing status, it means that the sampling data in the buffered recording area 10 is being processed by the computer system. It is a standby state, which means that the buffered recording area 10 is storing the sampled data. The size of the buffer recording area 10 will directly affect the continuity and time delay of the recorded sound. If the buffer recording area 10 is larger, the more and more complete sampling data can be recorded, resulting in better continuity of the recorded sound, but because the computer system must process more sampling data, it will cause the recorded data to be recorded. The time delay of the sound is worse; on the contrary, if the buffer recording area 10 is smaller, the time delay of the recorded sound can be improved, but the continuity of the sound will be worse. Therefore, the sounds recorded by Xizhi Technology cannot take into account both continuity and time delay. In addition, the practice of know-how is to cause the computer system to start fetching data in the buffered recording area 10 when there is insufficient space in the buffered recording area 10.

Description of the invention Sampling data into the recording area after sampling a buffer line until the work is equivalent and the main reason is [invention of this recording method, problems, and delay. In order to achieve this, the multi-line line is appropriate, and the data is recorded in the area. The brain system is used for processing. (2) The pre-processing data of line 10 is collected in the recorded area. Content] The master of the solution solves the above-mentioned problem in a micro-processing method, including: providing one (including: compression, storage, etc.), and then release the buffer state, and change to a processing state, so that Put it in another buffered recording area 10, and then set the state of the other domain to a standby state, so continuous recording is completed. It can be seen from the above that the computer system needs to be implemented in a trivial manner, which makes it impossible to continuously record sound data. The sound recorded by the know-how generally has poor continuity. The main purpose is to provide a record of continuous sound data. The sound has poor continuity. The recorded sound can take into account both continuity and time. This buffer thread is supplemented by another buffer record. In order to make you familiar with the purpose, a multi-processor: read the sample buffer above the record help. For the line area technology, the thread is used to take this: the recorded area is micro-processed by the present invention to supplement the data in one of the continuous sound sampling areas with the aid of audio data. Use the thread material; then continue the line material on the sound computer system. The material is not sequentially spaced. The continuous sound is recorded in the recording side during the process of the first and the sampling data mentioned above. At that time, the electric auxiliary thread is for a second auxiliary data to sequentially record the artisan to understand the purpose, characteristics and functions of the present invention.

Description of the invention (3) The following specific examples and the accompanying drawings are used to explain the present invention in detail as follows: [Embodiment] The present invention The spirit lies in the use of multi-thread (thread) technology for continuous sound data recording, that is, by creating multiple auxiliary threads to process the data in the buffer recording area 10 separately, and respond to the processing of the buffer recording area 1 An event with an insufficient space of 0. Therefore, the present invention is suitable to be implemented in a computer system having a multi-threaded microprocessor. As shown in FIG. 2, it is a structural diagram of a computer system that can be used by the present invention. In the second figure, the computer system includes at least an input / output device 20, a memory 2 2, a multi-threaded microprocessor 24, and a storage device 26. The computer system refers to an electronic device (not shown) such as a personal desktop computer, a notebook personal computer, a digital voice recorder, a digital personal assistant, or a mobile phone for users to perform recording processing. A method for recording continuous audio data according to the present invention will be described using a notebook personal computer. To simplify the drawings and description, the system architecture here only shows the system components related to the present invention, and other unrelated system components are not shown in the drawings. The input / output device 20 is mainly used to receive continuous sound data from the outside, such as a sound collector (microphone), and to play the sound data recorded by the computer system, such as a speaker (speaker): and memory The body 22 can be dynamically allocated with at least one buffered recording area 2 2 0. The logical structure of the buffered recording area 2 2 0 can be referred to as shown in FIG. 1, which is mainly used to store a computer system for continuous sound data. Sampled data; multi-threaded microprocessor 2 4 is used to detect the buffered record of the memory 2 2

Description of the invention (5) state, for the computer system to sequentially record the sampled data processed in the buffer recording area (2 2 2 or 2 2 4) which has been set to the standby state, and then Then return to step 300, so that the computer system repeatedly stores the processed sampling data until the continuous sound data is recorded. Among them, steps 304 to 305 shown in FIG. 3 can be processed in parallel with step 306, that is, the computer system processes the buffered recording area 2 2 0 filled with the sampled data on the one hand. On the other hand, another buffered recording area (2 2 2 or 2 2 4) is processed from the memory 22, so that the sampling data processed by the computer device is continuously stored, and among them, the storage The device 26 assists the processing of the computer system on data storage to solve the problem of discontinuous data storage, and provides a multi-threaded sound data storage technology. Therefore, the present invention can greatly shorten the processing time of the sampling data in the buffered recording area to improve the execution efficiency of the recording program; further, the buffered recording area in the processing state can be retracted in time, so that continuous sampling can be performed smoothly It is carried out, and indirectly, the memory space of the allocated buffered recording area can be reduced, thereby saving system resources. Since the present invention uses multi-threading technology, and the buffered recording area can be set to have a small memory space, the present invention has better time delay, and this advantage is especially applicable to the occasion of real-time transmission of voice data, such as videoconferencing Conferences, etc., and can simultaneously have the characteristics of continuity.
