Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides an audio playing method applied to a mobile terminal, including:
Specifically, in the step of acquiring the recording data acquired by the microphone cached in the recording thread, the recording data acquired by the microphone is sequentially subjected to signal conversion and encoding processing in the recording thread.
The recording data collected by the microphone is an analog signal. After the microphone collects the analog signal, the microphone transmits the analog signal to a codec (coder/decoder) for signal conversion and encoding, and after the codec converts the analog signal into a digital signal, the codec encodes the digital recording data according to a specific audio file format.
The digital audio data after being encoded by codec is transmitted to the audio mixer of the mobile terminal sequentially through the alsa driver (Advanced Linux Sound Architecture direct, Sound card driver) and the adaptation layer tinyalsa of the Sound card driver.
After receiving the digital audio data, the audio mixer of the mobile terminal encapsulates the digital audio data into a recording audio encapsulation packet, and specifically, the recording audio encapsulation packet is a unified encapsulation packet audio replay of audio data played by a native layer android system.
In the embodiment of the invention, the target application program divides the accompaniment sound of a song into three parts, namely, a prelude accompanying sound, a positive song accompanying sound and a tail accompanying sound in sequence. For positive song accompaniment, the target application program sends the accompaniment data corresponding to each sentence of lyrics.
And 102, mixing the sound of the recording data and the sound data.
Specifically, the step of mixing the sound recording data and the sound data includes:
specifically, the mixer acquires time stamps corresponding to audio frames of the recording data and audio frames and time stamps corresponding to audio frames of the accompanying data and audio frames of the accompanying data, superimposes the audio frames with the same time stamps in the recording data and the accompanying data to obtain a synthesized audio frame, the synthesized audio frame has an original time stamp, and generates the playing data according to the sequence of the time stamps from front to back, wherein the synthesized audio frame has the original time stamp, the synthesized audio frame has the audio frame which does not have the recording data and the recording data has the audio frame which does not have the accompanying data.
Fig. 2 is a schematic diagram of sound recording data and audio data mixed to obtain playback data according to an embodiment of the present invention, where, as shown in fig. 2, the sound recording data 20 and the audio data 30 each include a plurality of audio frames, and each audio frame has a respective time stamp. If audio frames with the same time stamp exist in the recorded sound data 20 and the audio data 30, the intelligent terminal superimposes the audio frames with the same time stamp in the recorded sound data 20 and the audio data 30, for example, superimposes the audio frame a1 and the audio frame b1 with the same time stamp to obtain a synthesized audio frame c1, superimposes the audio frame a3 and the audio frame b3 with the same time stamp to obtain a synthesized audio frame c2, and superimposes the audio frame a4 and the audio frame b6 with the same time stamp to obtain a synthesized audio frame c 3. Finally, the other audio frames of the audio record data 20 and the audio data 30 that are not superimposed and the resulting synthesized audio frames are sequentially generated into the play data 40 from front to back according to the time stamps.
And 103, sending the play data after the sound mixing processing to a play thread.
Specifically, in the step of sending the play data after the audio mixing process to the play thread, the play data is subjected to decoding process and signal conversion in the play thread.
And after receiving the playing data, the playing thread decodes the playing data according to a decoding mode corresponding to the coding mode adopted by the recording thread. For example, when the audio data is encoded by the recording thread using the encoding method corresponding to the PCM, the playback thread encodes the playback data using the decoding method corresponding to the PCM.
According to the audio playing method provided by the embodiment of the invention, the recording data acquired by the microphone is directly transmitted to the audio mixer through the recording thread, so that the transmission time of the recording data acquired by the microphone is reduced, the delay time of audio data playing is shortened, and the user experience is improved.
Further, in an embodiment of the present invention, referring to fig. 3, before the step of obtaining the audio data sent by the target application to the playback thread, the method further includes:
and 104, receiving an accompanying sound playing request sent by the target application program.
The audio playing request is a request of a target application program to a packaging space used by the mixer for storing audio data.
Since the target application divides the accompaniment data of the song into three parts (prelude, positive song and ending), the accompanying sound playing requests corresponding to the three parts of accompanying sound data are different. The target application program firstly divides the song accompanying sound data into three major parts, and divides the accompanying sound of the song part according to the accompanying sound data corresponding to each sentence of lyrics. The target application program packages each part of the audio data into an IAVA audio data package packet respectively. Before sending the audio data to the audio mixer, the IAVA audio data encapsulation packet needs to be converted into a c/c + + audio data encapsulation packet.
And 105, judging whether the accompanying sound playing request carries identification information for indicating that the accompanying sound data is lyric accompanying sound data or not.
Before sending the accompanying sound playing request, the target application program needs to add identification information in the accompanying sound playing request according to whether the accompanying sound data to be sent is the lyric accompanying sound data, if so, the audio mixer needs to determine that the accompanying sound data to be sent is the lyric accompanying sound data.
And step 106, if the identification information for indicating that the accompanying sound data is the lyric accompanying sound data is carried, sending first indication information of sending the accompanying sound data after delaying for a preset time to the target application program.
Specifically, the predetermined time is a predetermined time input by the user.
And after receiving the first indication information, the target application program sends the audio data to the mixer after the preset time.
In this process, since the target application delays sending the audio data, the audio data is not output at the playback thread for the predetermined time. The user can compare a sentence of lyrics which are just recorded in the preset time to determine whether the pronunciation of the lyrics and the tune are correct. Meanwhile, a user does not need to manually input a pause instruction, and the user experience is improved.
Further, in an embodiment of the present invention, the method further includes:
and step 107, if the accompanying sound playing request does not carry the identification information for indicating that the accompanying sound data is the lyric accompanying sound data, sending second indication information for immediately sending the accompanying sound data to the target application program.
If the accompanying sound playing request does not carry the identification information, the accompanying sound data to be sent to the sound mixer by the target application program is indicated to be prelude data or ending data. Therefore, the song accompaniment does not need to be paused, and the playing time of the accompaniment is shortened.
In the embodiment of the invention, the method for delaying the karaoke accompaniment to be played can be set as a special playing mode, namely, if the user does not start the playing mode, the target application program outputs the accompanying sound data according to the method for continuously outputting the accompanying sound data in the existing method; only when the user starts the play mode, the target application outputs the audio data in the manner of steps 104 to 107.
By the audio playing method provided by the embodiment of the invention, the audio playing delay time in the process of singing k is shortened, and meanwhile, the audio data of the part of the singing can be automatically delayed and played according to the time set by the user, so that the user can carefully check the singing song in time, the user does not need to manually input a pause instruction, and the user experience is improved.
