    • 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​(java.nio.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.
