具体实施方式
应当理解,此处所描述的具体实施例仅仅用以解释本发明,并不用于限定本发明。
本发明提供一种音频数据输出方法,在本发明音频数据输出方法的第一实施例中,参照图1,该音频数据输出方法包括:
步骤S10,当检测到终端播放待播放音频数据时,获取与终端连接的音频播放设备的工作频段;
当检测到终端(例如智能电视)播放待播放音频数据时,获取与该终端连接的各个音频播放设备(例如,音频播放设备为音响)的工作频段,一个或多个音频播放设备通过路由器与终端连接,该路由器中存有各个音频播放设备的名称和地址;此外,音频播放设备的工作频段为其硬件参数,例如音频播放设备的工作频段的分布如下:
工作频段A(超低音):20-40Hz; 工作频段B(低音):40-150Hz;工作频段C(中低音):150-500Hz;工作频段D(中音):500Hz-2KHz;工作频段E(中高音)2KHz-5KHz;工作频段F(高音)7KHz-8KHz。
步骤S20,基于各个音频播放设备的工作频段从待播放音频数据中分解出与各个音频播放设备对应的子音频数据;
根据各个音频播放设备的工作频段,将待播放音频数据分解出处于各个音频播放设备的子音频数据,例如音频播放设备的工作频段包括高、中、低三个频段,则将待播放音频数据分解出处于高、中、低三个频段的子音频数据,具体过程如下:先根据待播放音频数据的时间轴对该待播放音频数据进行一次谐振,去掉载频;然后根据高、中、低三个工作频段对一次谐振后的待播放音频数据进行二次谐振,以将待播放音频数据分解出处于高工作频段、中工作频段和低工作频段的三个子音频数据。
步骤S30,将各个子音频数据发送至该子音频数据对应的音频播放设备,以供各个音频播放设备同步播放子音频数据。
将各个子音频数据发送至该子音频数据对应的音频播放设备,以供各个音频播放设备同步播放子音频数据,如上述例子,待播放音频数据被分解为处于低工作频段、中工作频段和高工作频段的子音频数据,然后将处于低工作频段的子音频数据发送至低工作频段对应的音频播放设备,将处于中工作频段的子音频数据发送至中工作频段对应的音频播放设备,将处于高工作频段的子音频数据发送至高工作频段对应的音频播放设备。
在本实施例中,通过在检测到终端播放待播放音频数据时,获取与终端连接的音频播放设备的工作频段;然后基于各个音频播放设备的工作频段在待播放音频数据分解出与各个音频播放设备对应的子音频数据;最后将各个子音频数据发送至该子音频数据对应的音频播放设备,以供各个音频播放设备同步播放子音频数据,从而使音频播放设备根据自身的工作频段输出与该工作频段等级匹配的子音频数据,使音频播放设备输出均衡声效的音频数据,改善了外接音频播放设备输出音频数据的声音效果。
优选地,在本发明音频数据输出方法第一实施例的基础上,提出音频数据输出方法第二实施例,在第二实施例中,参照图2,步骤S20之后还包括:
步骤S40,根据待播放音频数据的时间轴信息,为各个子音频数据添加播放时间点;
待播放音频数据中包含时间轴信息,该时间轴信息标记了该待播放音频数据的播放时间点,当待播放音频数据被分解为多个子音频数据后,为各个子音频数据添加播放时间点,该播放时间点用于提示接收子音频数据的音频播放设备在播放时间点播放对应的子音频数据。
步骤S30包括:
步骤S31,将各个子音频数据和对应的播放时间点发送至该子音频数据对应的音频播放设备,以供各个音频播放设备在对应的播放时间点到达时,播放对应的子音频数据。
在本优选实施例中,通过为各个子音频数据添加播放时间点,当各个音频播放设备接收到包含播放时间点的子音频数据时,在播放时间点达到时播放接收的子音频数据,统一了子音频数据的输出时刻,提升了多音频播放设备同步输出待播放音频数据的同步声效效果,使音频播放设备输出的音频数据均衡声效效果更佳。
进一步地,在本发明音频数据输出方法第一实施例的基础上,提出音频数据输出方法的第三实施例,在第三实施例中,参照图3,步骤S20包括:
步骤S21,将待播放音频数据分解为与各个音频播放设备的工作频段对应子音频数据;
步骤S22,将各个工作频段对应的子音频数据与工作频段对应的音频播放设备关联;
为了更好理解方案,现举例说明本实施例,例如工作频段分为高工作频段、中工作频段和低工作频段,与终端连接的音频播放设备包括处于高工作频段的设备A和B、处于中工作频段的设备C以及处于低工作频段的设备D和E,将待播放音频数据分解为与高工作频段对应(即处于高工作频段内)的子音频数据1、与中工作频段对应的子音频数据2、与低工作频段对应的子音频数据3;然后将子音频数据1与设备A和B关联、将子音频数据2与设备C关联、将子音频数据3与设备D和E关联。
步骤S30包括:
步骤S32,将各个子音频数据发送至其关联的音频播放设备,以供各个音频播放设备同步播放子音频数据。
将各个子音频数据发送至其关联的音频播放设备,如上述例子中,将子音频数据1发送至设备A和B、将子音频数据2发送至设备C、将子音频数据3发送至设备D和E,从而各个音频播放设备同步播放接收到的子音频数据。
在本实施例中,将子音频数据准确地定位至对应的音频播放设备,减少了终端发送至音频播放设备所在网络的数据量,降低了终端与音频播放设备所组成网络的网络带宽需求,同时,音频播放设备只需被动接收并播放子音频数据即可,降低了对音频播放设备的硬件要求。
进一步地,在本发明音频数据输出方法第一实施例的基础上,提出该方法的第四实施例,参照图4,在第四实施例中,步骤S30之前还包括:
步骤S51,判断待播放音频数据分解出子音频数据后是否有剩余频段的音频数据;
步骤S52,若所述待播放音频数据分解出所述子音频数据后没有剩余频段的音频数据,则执行所述将各个所述子音频数据发送至该子音频数据对应的所述音频播放设备的步骤;
在待播放音频数据分解出各个音频播放设备对应的子音频数据后,判断该待播放音频数据分解出与各个音频播放设备对应的子音频数据后,是否还有剩余频段的音频数据。例如:当待播放音频数据的频段为1至1000 Hz,低工作频段为1至200 Hz,中工作频段为 201至400 Hz,高工作频段为 401至600 Hz,那么待播放音频数据分解出对应高、中、低工作频段的子音频数据后,还有剩余频段的音频数据(即处于601至1000 Hz 频段的音频数据);当待播放音频数据的频段为1至600 Hz,低工作频段为1至200 Hz,中工作频段为 201至400 Hz,高工作频段为 401至600 Hz,那么待播放音频数据分解出对应高、中、低工作频段的子音频数据后,没有剩余频段的音频数据。
在待播放音频数据分解出子音频数据后没有剩余频段的音频数据,即外接的音频播放设备具备播放所有频段的待播放音频数据的能力时,将各个子音频数据发送至该子音频数据对应的音频播放设备,以供各个音频播放设备同步播放子音频数据。
在步骤S51之后还包括:步骤S53,若所述待播放音频数据分解出所述子音频数据后有剩余频段的音频数据,则控制所述终端播放所述待播放音频数据分解出所述子音频数据后剩余频段的音频数据,并将各个所述子音频数据发送至该子音频数据对应的所述音频播放设备,以供各个所述音频播放设备同步播放所述子音频数据。
在本实施例中,在待播放音频数据分解出各个音频播放设备对应的子音频数据后,判断该待播放音频数据分解出与各个音频播放设备对应的子音频数据后,是否还有剩余频段的音频数据,在有剩余频段的音频数据时,控制工作频段范围较宽的终端播放该剩余频段的音频数据,而不是将剩余频段的音频数据发送至音频播放设备,避免了音频播放设备播放与其工作频段不匹配的音频数据而出现声音效果失真严重、声音效果差的问题,进一步提高了输出音频数据的声音效果。
优选地,步骤S53包括:
步骤S531,若待播放音频数据分解出子音频数据后有剩余频段的音频数据,则判断该剩余频段的音频数据对应的频段是否与终端的工作频段匹配;
步骤S532,若该剩余频段的音频数据对应的频段与终端的工作频段匹配,则控制终端播放待播放音频数据分解出子音频数据后剩余频段的音频数据,并将各个子音频数据发送至该子音频数据对应的音频播放设备,以供各个音频播放设备同步播放子音频数据。
当待播放音频数据分解出子音频数据后有剩余频段的音频数据时,即待播放音频数据中包含音频播放设备的工作频段之外的音频数据时,进一步判断该剩余频段的音频数据对应频段是否与终端的工作频段是否匹配,若终端的工作频段与待播放音频数据的剩余频段匹配,则控制终端播放待播放音频数据中在音频播放设备的工作频段之外的音频数据,并在待播放音频数据中分解出的子音频数据发送至与终端连接的对应音频播放设备,以供各个音频播放设备同步播放接收的子音频数据;若终端的工作频段与待播放音频数据的剩余频段不匹配,则控制终端发出提示信息(声音、图像、文字及其组合等)以告知用户终端和音频播放设备无法完全播出待播放音频数据的全部声音效果。
在本实施例中,避免了终端播放处于其工作频段之外的音频数据,进一步提高终端播放音频数据的声音效果。
