Class constructor.
[Android.Runtime.Register(".ctor", "(IIIII)V", "")]
[Android.Runtime.RequiresPermission("android.permission.RECORD_AUDIO")]
public AudioRecord (Android.Media.AudioSource audioSource, int sampleRateInHz, Android.Media.ChannelIn channelConfig, Android.Media.Encoding audioFormat, int bufferSizeInBytes);[<Android.Runtime.Register(".ctor", "(IIIII)V", "")>]
[<Android.Runtime.RequiresPermission("android.permission.RECORD_AUDIO")>]
new Android.Media.AudioRecord : Android.Media.AudioSource * int * Android.Media.ChannelIn * Android.Media.Encoding * int -> Android.Media.AudioRecordParameters
- audioSource
- AudioSource
the recording source.
See MediaRecorder.AudioSource for the recording source definitions.
- sampleRateInHz
- Int32
the sample rate expressed in Hertz. 44100Hz is currently the only
rate that is guaranteed to work on all devices, but other rates such as 22050,
16000, and 11025 may work on some devices.
AudioFormat#SAMPLE_RATE_UNSPECIFIED means to use a route-dependent value
which is usually the sample rate of the source.
#getSampleRate() can be used to retrieve the actual sample rate chosen.
- channelConfig
- ChannelIn
describes the configuration of the audio channels.
See AudioFormat#CHANNEL_IN_MONO and
AudioFormat#CHANNEL_IN_STEREO. AudioFormat#CHANNEL_IN_MONO is guaranteed
to work on all devices.
- audioFormat
- Encoding
the format in which the audio data is to be returned.
See AudioFormat#ENCODING_PCM_8BIT, AudioFormat#ENCODING_PCM_16BIT,
and AudioFormat#ENCODING_PCM_FLOAT.
- bufferSizeInBytes
- Int32
the total size (in bytes) of the buffer where audio data is written
to during the recording. New audio data can be read from this buffer in smaller chunks
than this size. See #getMinBufferSize(int, int, int) to determine the minimum
required buffer size for the successful creation of an AudioRecord instance. Using values
smaller than getMinBufferSize() will result in an initialization failure.
- Attributes
Exceptions
Remarks
Class constructor. Though some invalid parameters will result in an IllegalArgumentException exception, other errors do not. Thus you should call #getState() immediately after construction to confirm that the object is usable.
