Constructor Detail

Lame

public Lame(AudioFormat sourceFormat)

Initializes the decoder with DEFAULT_BITRATE, DEFAULT_CHANNEL_MODE, DEFAULT_QUALITY, and DEFAULT_VBR Throws IllegalArgumentException when parameters are not supported by LAME.

Lame

public Lame(AudioFormat sourceFormat,
            int bitRate,
            int channelMode,
            int quality,
            boolean VBR)

Initializes the decoder. Throws IllegalArgumentException when parameters are not supported by LAME.

Method Detail

getEncoderVersion

public String getEncoderVersion()

getPCMBufferSize

public int getPCMBufferSize()

Returns the buffer needed pcm buffer size. The passed parameter is a wished buffer size. The implementation of the encoder may return a lower or higher buffer size. The encoder must be initalized (i.e. not closed) at this point. A return value of <0 denotes an error.

getMP3BufferSize

public int getMP3BufferSize()

encodeBuffer

public int encodeBuffer(byte[] pcm,
                        int offset,
                        int length,
                        byte[] encoded)
                 throws ArrayIndexOutOfBoundsException

Encode a block of data. Throws IllegalArgumentException when parameters are wrong. When the encoded array is too small, an ArrayIndexOutOfBoundsException is thrown. length should be the value returned by getPCMBufferSize.

Returns:

the number of bytes written to encoded. May be 0.

Throws:

ArrayIndexOutOfBoundsException

encodeFinish

public int encodeFinish(byte[] encoded)

close

public void close()

isLibAvailable

public static boolean isLibAvailable()

getLinkError

public static String getLinkError()

getEffectiveQuality

public int getEffectiveQuality()

getEffectiveBitRate

public int getEffectiveBitRate()

getEffectiveChannelMode

public int getEffectiveChannelMode()

getEffectiveVBR

public boolean getEffectiveVBR()

getEffectiveSampleRate

public int getEffectiveSampleRate()

getEffectiveEncoding

public AudioFormat.Encoding getEffectiveEncoding()
