  • ResampleInputStream

    public ResampleInputStream(InputStream inputStream,
                       int rateIn,
                       int rateOut)

    Create a new ResampleInputStream, which converts the sample rate

    Parameters:

    inputStream - InputStream containing 16 bit PCM.

    rateIn - the input sample rate.

    rateOut - the output sample rate. This only handles rateIn == rateOut / 2 for the moment.

• Method Detail

  • read

    public int read()
             throws IOException

    Description copied from class: InputStream
    Reads a single byte from this stream and returns it as an integer in the range from 0 to 255. Returns -1 if the end of the stream has been reached. Blocks until one byte has been read, the end of the source stream is detected or an exception is thrown.

    Specified by:

    read in class InputStream

    Returns:

    the byte read or -1 if the end of stream has been reached.

    Throws:

    IOException - if the stream is closed or another IOException occurs.

  • read

    public int read(byte[] b)
             throws IOException

    Description copied from class: InputStream
    Equivalent to read(buffer, 0, buffer.length).

    Overrides:

    read in class InputStream

    Throws:

    IOException

  • read

    public int read(byte[] b,
           int offset,
           int length)
             throws IOException

    Description copied from class: InputStream
    Reads at most length bytes from this stream and stores them in the byte array b starting at offset.

    Overrides:

    read in class InputStream

    Parameters:

    b - the byte array in which to store the bytes read.

    offset - the initial position in buffer to store the bytes read from this stream.

    length - the maximum number of bytes to store in b.

    Returns:

    the number of bytes actually read or -1 if the end of the stream has been reached.

    Throws:

    IOException - if the stream is closed or another IOException occurs.

  • close

    public void close()
               throws IOException

    Description copied from class: InputStream
    Closes this stream. Concrete implementations of this class should free any resources during close. This implementation does nothing.

    Specified by:

    close in interface Closeable

    Specified by:

    close in interface AutoCloseable

    Overrides:

    close in class InputStream

    Throws:

    IOException - if an error occurs while closing this stream.

  • finalize

    protected void finalize()
                     throws Throwable

    Description copied from class: Object
    Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.

    Note that objects that override finalize are significantly more expensive than objects that don't. Finalizers may be run a long time after the object is no longer reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup. Note also that finalizers are run on a single VM-wide finalizer thread, so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary for a class that has a native peer and needs to call a native method to destroy that peer. Even then, it's better to provide an explicit close method (and implement Closeable), and insist that callers manually dispose of instances. This works well for something like files, but less well for something like a BigInteger where typical calling code would have to deal with lots of temporaries. Unfortunately, code that creates lots of temporaries is the worst kind of code from the point of view of the single finalizer thread.

    If you must use finalizers, consider at least providing your own ReferenceQueue and having your own thread process that queue.

    Unlike constructors, finalizers are not automatically chained. You are responsible for calling super.finalize() yourself.

    Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.

    Overrides:

    finalize in class Object

    Throws:

    Throwable
