Step S101: the audio stream information that reads material file to be edited;
Step S102: judge whether to import editing system by monophonic mode according to the said audio stream information that obtains that reads; If then go to step S103, then the audio stream of independent sound channel is made as a whole importing editing system and done as a whole editor if not; Wherein, the pattern of audio stream importing editing system can select the mixed layer sound channel pattern also can select monophonic mode.
Step S103: with each sound channel of said audio stream information as one independently audio stream import in the editing system;
Step S104: the independent audio stream of importing is arranged according to the mode of " L-R-L-R ... "
Step S105: each audio stream to independently appearing on the editing rail is edited.
Below in conjunction with concrete application scenarios; Above method is done to describe; With avi file with the audio frequency of form of audio frequency and AC-3 be that example is introduced mentality of designing, cited here embodiment has been merely better explanation technical scheme of the present invention, does not regard it as and exceeds; The document handling modus of extended formatting roughly the same all belongs within the scope of the present invention's protection.
We can be combined into an audio material of looking that contains audiovisual information with an avi file and some wav file in embodiments of the invention two; This is looked possibly include a plurality of monophonys or a stereosonic audio stream in the audio material; Adopt the method for monophonic mode import system of the present invention, be specially:
Step S201: read the audio material of looking that contains audio-frequency information, this material is will include the audio stream that includes a plurality of monophonys or a stereo channel that avi file and some wav file make up together through certain rule.
Step S202: judge whether to import editing system by monophonic mode, can select the mixed layer sound channel pattern to import audio material in this step and also can select monophonic mode to import audio material, for the ease of individually-edited, present embodiment is selected monophonic mode.
Step S203: with each sound channel as one independently audio stream import in the editing system.The said audio material of looking includes a plurality of monophonys, therefore said each monophony is imported as each audio stream inequality.
