The number of audio channels in the media recorder.

Returns

Self for chaining

bitRate

public MediaRecorderBuilder bitRate(int bitRate)
Sets the bit rate for the recorder. Default 64000.

Parameters

bitRate int
The bit rate for the recorder.

Returns

Self for chaining.

samplingRate

public MediaRecorderBuilder samplingRate(int samplingRate)
Sets the sampling rate for the recorder. Default 44100

Parameters

samplingRate int
The sample rate for the recorder.

Returns

Self for chaining.

public MediaRecorderBuilder path(String path)
Sets the output path where the audio recording should be saved.

Parameters

path String

Returns

Self for chaining.

redirectToAudioBuffer

public MediaRecorderBuilder redirectToAudioBuffer(boolean redirect)
Set this flag to true to redirect the microphone input to an audio buffer. This is handy if you just want to capture the raw PCM data from the microphone.

Parameters

redirect boolean
True to redirect output to an audio buffer. The #path(java.lang.String) parameter would then be used as the path to the audio buffer instead of the output file.

Returns

Self for chaining.

Throws

IOException
IllegalStateException
If #path(java.lang.String) is not set.

getAudioChannels

public int getAudioChannels()
Gets the current audio channels settings.

Returns

the audioChannels

getBitRate

public int getBitRate()
Gets the current bit rate.

Returns

the bitRate

getSamplingRate

public int getSamplingRate()
Gets the current sampling rate.

Returns

the samplingRate

getMimeType

public String getMimeType()
Gets the current mimetype.

Returns

the mimeType

getPath

public String getPath()
Gets the current output path.

Returns

the path

isRedirectToAudioBuffer

public boolean isRedirectToAudioBuffer()
