Method Detail

readInByteArray

default int readInByteArray(byte[] audioData,
                            int offsetInBytes,
                            int sizeInBytes,
                            boolean isBlocking)

Provides backing data for AudioRecord.read(byte[], int, int) and AudioRecord.read(byte[], int, int, int).

Returns:

Either a non-negative value representing number of bytes that have been written from the offset or a negative error code.

readInShortArray

default int readInShortArray(short[] audioData,
                             int offsetInShorts,
                             int sizeInShorts,
                             boolean isBlocking)

Provides backing data for AudioRecord.read(short[], int, int) and AudioRecord.read(short[], int, int, int).

Returns:

Either a non-negative value representing number of bytes that have been written from the offset or a negative error code.

readInFloatArray

default int readInFloatArray(float[] audioData,
                             int offsetInFloats,
                             int sizeInFloats,
                             boolean isBlocking)

Provides backing data for AudioRecord.read(float[], int, int, int).

Returns:

Either a non-negative value representing number of bytes that have been written from the offset or a negative error code.

readInDirectBuffer

default int readInDirectBuffer(ByteBuffer buffer,
                               int sizeInBytes,
                               boolean isBlocking)

Provides backing data for AudioRecord.read(byte[], int, int) and AudioRecord.read(byte[], int, int, int).

Returns:

Either a non-negative value representing number of bytes that have been written from the offset or a negative error code. Note any position/limit changes to the buffer will not be visible to the caller of the AudioRecord methods.
