+# OpenSL ES Audio Recording Development
+
+## When to Use
+
+You can use OpenSL ES to develop the audio recording function in OpenHarmony. Currently, only some
+[OpenSL ES APIs](https://gitee.com/openharmony/third_party_opensles/blob/master/api/1.0.1/OpenSLES.h) are implemented. If an API that has not been implemented yet is called, **SL_RESULT_FEATURE_UNSUPPORTED** will be returned.
+
+ 
+
+## How to Develop
+
+To use OpenSL ES to develop the audio recording function in OpenHarmony, perform the following steps:
+
+1. Add the header files.
+
+    ```c++
+    #include <OpenSLES.h>
+    #include <OpenSLES_OpenHarmony.h>
+    #include <OpenSLES_Platform.h>
+    ```
+
+2. Use the **slCreateEngine** API to create and instantiate the **engine** instance.
+
+    ```c++
+    SLObjectItf engineObject = nullptr;
+    slCreateEngine(&engineObject, 0, nullptr, 0, nullptr, nullptr);
+    (*engineObject)->Realize(engineObject, SL_BOOLEAN_FALSE);
+    ```
+
+    
+
+3. Obtain the **engineEngine** instance of the **SL_IID_ENGINE** interface.
+
+    ```c++
+    SLEngineItf engineItf = nullptr;
+    result = (*engineObject)->GetInterface(engineObject, SL_IID_ENGINE, &engineItf);
+    ```
+
+    
+
+4. Configure the recorder information (including the input source **audiosource** and output source **audiosink**), and create a **pcmCapturerObject** instance.
+
+    ```c++
+    SLDataLocator_IODevice io_device = {
+        SL_DATALOCATOR_IODEVICE,
+        SL_IODEVICE_AUDIOINPUT,
+        SL_DEFAULTDEVICEID_AUDIOINPUT,
+        NULL
+    };
+
+    SLDataSource audioSource = {
+        &io_device,
+        NULL
+    };
+
+    SLDataLocator_BufferQueue buffer_queue = {
+        SL_DATALOCATOR_BUFFERQUEUE,
+        3
+    };
+
+    // Configure the parameters based on the audio file format.
+    SLDataFormat_PCM format_pcm = {
+        SL_DATAFORMAT_PCM,
+        OHOS::AudioStandard::AudioChannel::MONO,
+        OHOS::AudioStandard::AudioSamplingRate::SAMPLE_RATE_44100,
+        OHOS::AudioStandard::AudioSampleFormat::SAMPLE_S16LE,
+        0,
+        0,
+        0
+    };
+
+    SLDataSink audioSink = {
+        &buffer_queue,
+        &format_pcm
+    };
+    
+    SLObjectItf pcmCapturerObject = nullptr;
+    result = (*engineItf)->CreateAudioRecorder(engineItf, &pcmCapturerObject,
+        &audioSource, &audioSink, 0, nullptr, nullptr);
+    (*pcmCapturerObject)->Realize(pcmCapturerObject, SL_BOOLEAN_FALSE);
+    ```
+
+5. Obtain the **recordItf** instance of the **SL_IID_RECORD** interface.
+
+    ```
+    SLRecordItf  recordItf;
+    (*pcmCapturerObject)->GetInterface(pcmCapturerObject, SL_IID_RECORD, &recordItf);
+    ```
+
+6. Obtain the **bufferQueueItf** instance of the **SL_IID_OH_BUFFERQUEUE** interface.
+
+    ```
+    SLOHBufferQueueItf bufferQueueItf;
+    (*pcmCapturerObject)->GetInterface(pcmCapturerObject, SL_IID_OH_BUFFERQUEUE, &bufferQueueItf);
+    ```
+
+    
+
+7. Register the **BufferQueueCallback** function.
+
+    ```c++
+    static void BufferQueueCallback(SLOHBufferQueueItf bufferQueueItf, void *pContext, SLuint32 size)
+    {
+        AUDIO_INFO_LOG("BufferQueueCallback");
+        FILE *wavFile = (FILE *)pContext;
+        if (wavFile != nullptr) {
+            SLuint8 *buffer = nullptr;
+            SLuint32 pSize = 0;
+            (*bufferQueueItf)->GetBuffer(bufferQueueItf, &buffer, pSize);
+            if (buffer != nullptr) {
+                fwrite(buffer, 1, pSize, wavFile);
+                (*bufferQueueItf)->Enqueue(bufferQueueItf, buffer, size);
+            } 
+        }
+
+        return;
+    }
+    
+    // Set wavFile_ to the descriptor of the file to be recorded.
+    (*bufferQueueItf)->RegisterCallback(bufferQueueItf, BufferQueueCallback, wavFile_);
+    ```
+
+
+8. Start audio recording.
+
+    ```c++
+    static void CaptureStart(SLRecordItf recordItf, SLOHBufferQueueItf bufferQueueItf, FILE *wavFile)
+    {
+        AUDIO_INFO_LOG("CaptureStart");
+        (*recordItf)->SetRecordState(recordItf, SL_RECORDSTATE_RECORDING);
+        if (wavFile != nullptr) {
+            SLuint8* buffer = nullptr;
+            SLuint32 pSize = 0;
+            (*bufferQueueItf)->GetBuffer(bufferQueueItf, &buffer, pSize);
+            if (buffer != nullptr) {
+                AUDIO_INFO_LOG("CaptureStart, enqueue buffer length: %{public}lu.", pSize);
+                fwrite(buffer, 1, pSize, wavFile);
+                (*bufferQueueItf)->Enqueue(bufferQueueItf, buffer, pSize);
+            } else {
+                AUDIO_INFO_LOG("CaptureStart, buffer is null or pSize: %{public}lu.", pSize);
+            }
+        }
+
+        return;
+    }
+    ```
+
+
+9. Stop audio recording.
+
+    ```c++
+    static void CaptureStop(SLRecordItf recordItf)
+    {
+        AUDIO_INFO_LOG("Enter CaptureStop");
+        fflush(wavFile_);
+        (*recordItf)->SetRecordState(recordItf, SL_RECORDSTATE_STOPPED);
+        (*pcmCapturerObject)->Destroy(pcmCapturerObject);
+        fclose(wavFile_);
+        wavFile_ = nullptr;
+        return;
+    }  
+    ```
