◆ sfSoundBufferRecorder_create()
Create a new sound buffer recorder.
- Returns
- A new sfSoundBufferRecorder object (NULL if failed)
◆ sfSoundBufferRecorder_destroy()
Destroy a sound buffer recorder.
- Parameters
-
soundBufferRecorder | Sound buffer recorder to destroy |
◆ sfSoundBufferRecorder_getBuffer()
Get the sound buffer containing the captured audio data.
The sound buffer is valid only after the capture has ended. This function provides a read-only access to the internal sound buffer, but it can be copied if you need to make any modification to it.
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
- Returns
- Read-only access to the sound buffer
◆ sfSoundBufferRecorder_getDevice()
Get the name of the current audio capture device.
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
- Returns
- The name of the current audio capture device
◆ sfSoundBufferRecorder_getSampleRate()
Get the sample rate of a sound buffer recorder.
The sample rate defines the number of audio samples captured per second. The higher, the better the quality (for example, 44100 samples/sec is CD quality).
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
- Returns
- Sample rate, in samples per second
◆ sfSoundBufferRecorder_setDevice()
Set the audio capture device.
This function sets the audio capture device to the device with the given name. It can be called on the fly (i.e: while recording). If you do so while recording and opening the device fails, it stops the recording.
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
name | The name of the audio capture device |
- Returns
- sfTrue, if it was able to set the requested device
◆ sfSoundBufferRecorder_start()
Start the capture of a sound recorder recorder.
The sampleRate parameter defines the number of audio samples captured per second. The higher, the better the quality (for example, 44100 samples/sec is CD quality). This function uses its own thread so that it doesn't block the rest of the program while the capture runs. Please note that only one capture can happen at the same time.
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
sampleRate | Desired capture rate, in number of samples per second |
- Returns
- sfTrue, if it was able to start recording
◆ sfSoundBufferRecorder_stop()
Stop the capture of a sound recorder.
- Parameters
-
soundBufferRecorder | Sound buffer recorder object |
