In the Bluetooth communication, when voice data is uplink, an uplink task source ULTaskSource is responsible for reading data from an MIC end of electronic equipment in a recording mode, and an audio interface is directly adopted to drive an audio driver to read the data of the Bluetooth equipment. ULTasksink transmits Bluetooth device data to the smart phone through the Bluetooth drive. When voice data is downlink, a downlink task source DLTaskSource acquires data from the smart phone through Bluetooth driving, and DLTasksink realizes that mobile phone end data is played through Bluetooth equipment.
Referring to fig. 2, fig. 2 is a schematic flowchart of a recording method provided in an embodiment of the present application, and the recording method is applied to an electronic device, where the electronic device includes a bluetooth telephone recording module and a system recording module, and as shown in the figure, the recording method includes:
s201, the electronic equipment creates a first sound recording thread, a first shared memory and a second shared memory;
the first recording thread is independent of the Bluetooth telephone recording thread and other recording threads except the other recording threads comprising the system recording thread, and is responsible for reading audio data, and simultaneously the Bluetooth telephone recording thread and the other recording threads are modified and do not read the audio data any more; after the audio data is stored in the first shared memory, the audio record is used for accessing the audio data, namely the audio record and the first recording thread record thread transmit data and use the first shared memory, or after the audio data is stored in the second shared memory, the audio data is used for the HfpUlTaskSource to access the audio data, namely the Bluetooth telephone uses and the first recording thread record thread transmit data and use the second shared memory.
In a specific implementation, the Audio service calls the adev _ open to obtain an Audio device processing function, and common modification of the first recording thread, the first shared memory and the second shared memory is added on the basis of a native code, which is an operation performed when the Audio service is initialized after the system is started.
S202, when the electronic equipment detects that the Bluetooth telephone recording module and the system recording module are both started, a first synchronization mechanism is adopted to start the first recording thread and collect first audio data;
the first synchronization mechanism may use a semaphore mechanism to set a flag, such as RecordNum, for the first recording thread, indicating the number of modules currently requiring to record audio data.
In a specific implementation, the first synchronization mechanism prepares to start the first recording thread RecordThread, and if the current RecordNum is equal to 0, the start is successful, and recording is started. For example, in the bluetooth call process, when other APPs reuse the system for recording, the electronic device adopts a first synchronization mechanism to start a first recording thread to acquire first audio data.
S203, the electronic equipment performs preset processing on the first audio data to obtain second audio data in a preset format;
in a specific implementation, the first audio data is pcm audio with a sampling rate of 16k and a sampling bit number of 16bit, which is acquired by the RecordThread through the tinyalsa interface, and the first audio data is subjected to preset processing to obtain second audio data.
S204, the electronic equipment sends the second audio data to the system recording module through the first shared memory, and sends the first audio data to the Bluetooth telephone recording module through the second shared memory by adopting a second synchronization mechanism;
the second audio data are stored in the first shared memory, then the audio data are read from the first shared memory, and the second audio data are processed by using a noise reduction algorithm and then sent to the system recording module; and storing the first audio data in the second shared memory, optimizing the first audio data and sending the optimized first audio data to a Bluetooth telephone recording module.
S205, the electronic device saves the second audio data as a first audio file through the system recording module, and saves the second audio data as a second audio file through the Bluetooth telephone recording module.
It can be seen that, in the embodiment of the present application, the electronic device first creates a first recording thread, a first shared memory, and a second shared memory; then when detecting that the Bluetooth telephone recording module and the system recording module are both started, starting the first recording thread by adopting a first synchronization mechanism, and acquiring first audio data; secondly, performing preset processing on the first audio data to obtain second audio data in a preset format; sending the second audio data to the system recording module through the first shared memory again, and sending the first audio data to the Bluetooth telephone recording module through the second shared memory by adopting a second synchronization mechanism; and finally, the second audio data is saved as a first audio file through the system recording module, and the first audio data is saved as a second audio file through the Bluetooth telephone recording module. Therefore, the electronic equipment creates the first recording thread, the first shared memory and the second shared memory, then adopts the first synchronization mechanism to send the processed second audio data to the system recording module, and samples the second synchronization mechanism to send the collected first audio data to the Bluetooth telephone recording module, so that the Bluetooth telephone and the system recording are parallel, and the user experience is improved.
In one possible example, the starting the first recording thread using a first synchronization mechanism to collect first audio data includes: starting the first recording thread by calling a first preset function and adopting the first synchronization mechanism; and reading first audio data by the first recording thread by using an audio interface.
The first preset function is a start _ input _ stream function, the start _ input _ stream function uses a first synchronization mechanism to prepare to start the first recording thread, and the first recording thread drives an Audio Driver to read first Audio data with a sampling rate of 16k and a sampling bit number of 16 bits through an Audio interface tinyalsa interface.
As can be seen, in this example, the electronic device can start the first recording thread through the first synchronization mechanism, and then acquire the first audio data through the first recording thread, thereby ensuring the execution order of the processes.
In one possible example, the performing the preset processing on the first audio data to obtain the second audio data in the preset format includes: and resampling the first audio data to obtain second audio data in a preset format, wherein the preset format comprises a sampling rate as a preset value and a sampling digit as a preset sampling digit.
The preset format includes, but is not limited to, a preset sampling rate and a preset number of sampling bits, and the preset processing includes, but is not limited to, audio optimization processing of resampling.
In a specific implementation, while the first recording thread acquires first audio data, the first audio data may be subjected to SRC resampling, and the first audio data may be subjected to down-sampling or up-sampling, so as to acquire pcm audio data with a sampling rate of a and a sampling bit number of a.
Therefore, in this example, the electronic device can resample based on the first audio data to obtain the second audio data suitable for the system recording module, so that the requirement of the system recording module on the audio data can be met, and the stability of system recording is facilitated.
In one possible example, the sending the first audio data to the bluetooth voice recording module through the second shared memory using a second synchronization mechanism includes: storing the first audio data to the second shared memory; reading the first audio data from the second shared memory, and performing echo cancellation processing on the first audio data; and sending the processed first audio data to the Bluetooth telephone recording module.
And the Bluetooth telephone task source calls a Read function to Read the first audio data from the second shared memory, and the first audio data is subjected to echo cancellation and then sent to the Bluetooth telephone recording module.
In the concrete implementation, the first recording thread mark RecordNum is 1, the first recording thread mark RecordNum is added with 1, the first recording thread mark RecordNum is 2, and first audio data obtained by recording through the first recording thread is sent to the Bluetooth telephone recording module through the second shared memory.
In the specific implementation, the bluetooth telephone system recording module may further use an inter-process communication mechanism to acquire the first audio data, that is, the first recording thread RecordThread serves as a server for inter-process communication, when the first recording thread RecordThread reads a part of data, the part of data is sent to the client-side bluetooth telephone recording module hfputtasksource for inter-process communication through a send function, and the bluetooth telephone recording module receives the audio data through a recv function and performs necessary processing on the data.
As can be seen, in this example, since the electronic device can store the first audio data in the second shared memory through the second synchronization mechanism, and then read the first audio data and perform echo cancellation processing on the first audio data, it is ensured that only one thread of the concurrent threads can access the shared data at the same market price, and the audio is directionally enhanced and echo cancelled, thereby improving the user call effect.
In one possible example, before the first audio data is transmitted to the bluetooth voice recording module through the second shared memory using a second synchronization mechanism, the method further comprises: detecting whether the first recording thread is started or not; and if the first recording thread is not started, starting the first recording thread by calling a second preset function and adopting a second synchronization mechanism, wherein the first recording thread is used for reading first audio data.
The second synchronization mechanism may be the same mechanism as the first synchronization mechanism, or may be a different mechanism. The second preset function is a Start function.
In a specific implementation, before sending the first audio data, it is detected whether a first recording thread flag RecordNum is equal to 0, if the first recording thread flag RecordNum is not equal to 0, it is indicated that the first recording thread recordnthread is already started, the first recording thread does not need to be started again, the first recording thread recordnthread is started only once, and after the first recording thread is started, the first recording thread is not started again under the condition of no pause. If the first recording thread mark RecordNum is equal to 0 and the first recording thread RecordThread is not started, controlling the Bluetooth telephone HfpUlTaskSource to call the Start function and starting the first recording thread by adopting a second synchronization mechanism, and driving the Audio Driver to read the first Audio data through the first recording thread.
Therefore, in this example, the electronic device can determine whether to start the first recording thread through the second synchronization mechanism by detecting whether to start the first recording thread, so as to ensure that the first recording thread is started only once, thereby ensuring the accuracy and the uniformity of the recording data.
In one possible example, after the sending the second audio data to the system recording module through the first shared memory, the method further includes: when detecting that the system recording module does not have a recording requirement, stopping sending the second audio data to the system recording module by adopting the first synchronization mechanism; detecting whether the Bluetooth telephone recording module has a recording requirement; when the Bluetooth telephone recording module has a recording requirement, the first audio data is sent to the Bluetooth telephone recording module through the first recording thread; and when the Bluetooth telephone recording module does not have the recording requirement, the Bluetooth telephone recording module exits from the first recording thread.
When detecting that the system recording module does not need to record data, calling a stop _ input _ stream function to start the first synchronization mechanism to stop recording, namely stopping sending second audio data to the system recording module through the first shared memory. And detecting whether the Bluetooth telephone recording module needs to record data or not, if so, requiring the first recording thread to operate to provide first recording data, and if not, stopping the first recording thread.
In specific implementation, when the system recording module does not need to record data any more, a stop _ input _ stream function is called, first, the RecordNum is subtracted by 1, and then the RecordNum is equal to 1, which indicates that other modules (bluetooth phones) need to record data. Then, the first recording thread RecordThread is ready to be stopped, because the current RecordNum is equal to 1, which indicates that other modules still need the first recording thread RecordThread to operate to provide the recording data. There is no need to stop the first record thread RecordThread. If the Bluetooth telephone does not need the recording data any more, a stop function is called, the RecordNum is firstly reduced by 1, and the RecordNum is 0, which means that no module needs the recording data. Then the first recording thread RecordThread is ready to be stopped, since the current RecordNum is 0, the first recording thread RecordThread is stopped.
It is thus clear that in this example, electronic equipment can detect whether bluetooth telephone recording has the recording demand to decide when system's recording does not have the recording demand the continuation of first recording thread is started or is withdrawed from, has guaranteed to make full use of first recording thread and the stability of bluetooth telephone recording after system's recording stops.
In one possible example, after the transmitting the first audio data to the bluetooth voice recording module through the second shared memory using the second synchronization mechanism, the method further includes: when detecting that the Bluetooth telephone recording module does not have a recording requirement, stopping sending the first audio data to the Bluetooth telephone recording module by adopting the second synchronization mechanism; detecting whether the recording module of the system has a recording requirement; when the system recording module has a recording requirement, the second audio data is sent to the system recording module through the first recording thread; and when the system recording module does not have a recording requirement, the first recording thread is quitted.
When the Bluetooth telephone recording module is detected not to need recording data, a Stop function is called to start the second synchronization mechanism to Stop recording, namely, the first audio data is stopped from being sent to the Bluetooth telephone recording module through the second shared data. And detecting whether the system recording module needs to record data or not, if so, continuing to operate the first recording thread to acquire first audio data and provide the first audio data for the system recording module, and if not, stopping the first recording thread.
In the concrete implementation, when the bluetooth telephone recording module no longer needs recording data, call stop function start the second synchronization mechanism stops recording, and current RecordNum is 2, represents bluetooth telephone recording module with system recording module all needs recording data, subtracts 1 from RecordNum earlier, and then RecordNum is 1, represents that other modules (system recording) need recording data still. Then, the first recording thread RecordThread is ready to be stopped, because the current RecordNum is equal to 1, which indicates that other modules still need the first recording thread RecordThread to operate to provide the recording data. There is no need to stop the first record thread RecordThread. If the system recording does not need to record data any more, the stop _ input _ stream function is called to stop recording, and the RecordNum is firstly reduced by 1, then the RecordNum is 0, which means that no module needs to record data. Then the first recording thread RecordThread is ready to be stopped, since the current RecordNum is 0, the first recording thread RecordThread is stopped.
It is thus clear that in this example, electronic equipment when the bluetooth phone recording does not have the recording demand, whether detection system recording has the recording demand to decide continuation start-up or withdraw from of first recording thread has guaranteed to be to make full use of first recording thread and the stability of bluetooth phone recording system's recording after stopping.
