[0004] However, multiple steps in the above-mentioned whole process will bring loss to the sound signal collected at the beginning, especially in the compression coding process, it is very easy to filter out part of the audio in the sound signal, such as high-frequency information and spatial information
As a result, the user ends up with an audio file with poor sound quality

The invention provides a method and a device for obtaining an internet audio file. The method for obtaining the internet audio file includes steps: using a voice pickup device to pick up a first voice signal; perform voice mixing processing on the first voice signal so as to obtain a second voice signal; compensating an audio signal portion of the second voice signal in advance so as to obtain a third voice signal; performing compressed encoding on the third voice signal so as to obtain the internet audio file, wherein audio portion loss generated by the compressed encoding for the third voice signal includes the audio signal portion of the second voice signal, compensated in advance. According to the method and the device for obtaining the internet audio file, a pre-compensation mode is adopted to compensate the lost audio signal portion for the second voice signal, and therefore original voice of the third voice signal is reserved to the utmost in the internet audio file obtained by performing the compressed encoding on the third voice signal, and then the loss brought by the compressed encoding to the third voice signal is reduced during the obtaining process of the internet audio file, and voice quality of the internet audio file is improved.
Description
technical field [0001] The present application relates to the technical field of sound signal processing, in particular to a method and device for obtaining Internet audio files. Background technique [0002] With the continuous development of Internet technology, more and more people use the method of network download or online listening to obtain audio files, such as music. The main features of Internet music are: compressed and encoded small data audio files and earphone listening methods. It is well known that high-end audio file formats include CD (Compact Disk, Laser Disc), DSD (Direct Stream Digital, Direct Stream Digital Record), etc. These audio file formats have a large amount of data, and the storage cost and transmission cost are not suitable for the Internet field. application. In order to be suitable for the Internet, many compressed and encoded audio file formats have appeared in recent years, such as: MP3 (Moving Picture Experts Group Audio Layer III, movin...
