Problems solved by technology

The above method mainly has the following defects: some sound cards do not provide internal recording function, and cannot perform internal recording; even if the sound card provides internal recording function, but its implementation method is fixed, and the output audio data accuracy and format cannot be flexibly customized
However, the above solution cannot record the individual audio channels in the system
For example, if music A and music B are played in the system at the same time, only the sound of music A and music B can be recorded when recording, but music A or music B cannot be recorded separately

Embodiment Construction

[0015] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0016] figure 1 Shown is a flowchart of the audio recording method provided according to the first preferred embodiment of the present invention. like figure 1 As shown, the audio recording method provided by the first preferred embodiment of the present invention includes steps 101-105.

[0017] In step 101, the audio playback device calls a custom audio processing interface (API) to copy and store the audio data to be played into the data buffer, and calls the system audio processing interface through the custom audio processing interface to transmit the audio data to the audio device to play. Wherein, the audio playback device can directly call the custom audio processing interface, or replace...

Abstract

The invention provides an audio recording method and a system thereof. The method comprises the following steps: 1, an audio player calls a self-defined audio processing interface to copy audio data to be played to a datum buffer zone, and the self-defined audio processing interface calls a system audio processing interface to transmit the audio data to an audio device to play; and 2, after the audio data are played by the audio device, an audio recorder determines whether the recording of the audio data is needed, and the audio data stored in the datum buffer zone are recorded if the recording is needed.

Description

technical field [0001] The invention belongs to audio processing technology, in particular to an audio recording method and system. Background technique [0002] In the prior art, the problem of audio recording is usually solved by internal recording of the sound card. The internal recording method mainly realizes the acquisition of various audio sources (such as system sound, software sound, network music, etc.) through the recording port provided by the sound card driver. The above-mentioned method mainly has the following defects: some sound cards do not provide internal recording function and cannot perform internal recording; even if the sound card provides internal recording function, its implementation method is fixed, and the output audio data accuracy and format cannot be flexibly customized. [0003] In addition, the patent application for invention with application number 200910108442.7 (named "A Method and System for Audio Recording") provides a technical soluti...
