- * A standard registry of file type names will - * be maintained by the Tritonus team. - *

- * In a specification request to JavaSoft, these static methods - * could be integrated intoAudioFileFormat.Type. The static - * instances of AIFF, AIFC, AU, SND, and WAVE types in class - * AudioFileFormat.Type should be retrieved - * using this method, too (internally).
- * At best, the protected constructor of that class - * should also be replaced to be a private constructor. - * Like this it will be prevented that developers create - * instances of Type, which causes problems with the - * equals method. In fact, the equals method should be redefined anyway - * so that it compares the names and not the objects. - *

- * Also, the file name extension should be deprecated and moved - * to AudioFileFormat. There are some file formats - * which have varying extensions depending, e.g. on the encoding. - * An example for this is MPEG: the special encoding Mpeg 1, layer 3 - * has the extension mp3, whereas other Mpeg files use mpeg or mpg.
- * This could be implemented with 2 methods in AudioFileFormat: - *

  1. String[] getFileExtensions(): returns all usable extensions - * for this file. - *

- * It is supposed to be a replacement of the byte[] stream - * architecture of JavaSound, especially for chains of - * AudioInputStreams. Ideally, all involved AudioInputStreams - * handle reading into a FloatSampleBuffer. - *

- * Specifications: - *

    - *
  1. Channels are separated, i.e. for stereo there are 2 float arrays - * with the samples for the left and right channel - *
  2. All data is handled in samples, where one sample means - * one float value in each channel - *
  3. All samples are normalized to the interval [-1.0...1.0] - *
- *

- * When a cascade of AudioInputStreams use FloatSampleBuffer for - * processing, they may implement the interface FloatSampleInput. - * This signals that this stream may provide float buffers - * for reading. The data is not converted back to bytes, - * but stays in a single buffer that is passed from stream to stream. - * For that serves the read(FloatSampleBuffer) method, which is - * then used as replacement for the byte-based read functions of - * AudioInputStream.
- * However, backwards compatibility must always be retained, so - * even when an AudioInputStream implements FloatSampleInput, - * it must work the same way when any of the byte-based read methods - * is called.
- * As an example, consider the following set-up:
- *

    - *
  • auAIS is an AudioInputStream (AIS) that reads from an AU file - * in 8bit pcm at 8000Hz. It does not implement FloatSampleInput. - *
  • pcmAIS1 is an AIS that reads from auAIS and converts the data - * to PCM 16bit. This stream implements FloatSampleInput, i.e. it - * can generate float audio data from the ulaw samples. - *
  • pcmAIS2 reads from pcmAIS1 and adds a reverb. - * It operates entirely on floating point samples. - *
  • The method that reads from pcmAIS2 (i.e. AudioSystem.write) does - * not handle floating point samples. - *
- * So, what happens when a block of samples is read from pcmAIS2 ? - *
    - *
  1. the read(byte[]) method of pcmAIS2 is called - *
  2. pcmAIS2 always operates on floating point samples, so - * it uses an own instance of FloatSampleBuffer and initializes - * it with the number of samples requested in the read(byte[]) - * method. - *
  3. It queries pcmAIS1 for the FloatSampleInput interface. As it - * implements it, pcmAIS2 calls the read(FloatSampleBuffer) method - * of pcmAIS1. - *
  4. pcmAIS1 notes that its underlying stream does not support floats, - * so it instantiates a byte buffer which can hold the number of - * samples of the FloatSampleBuffer passed to it. It calls the - * read(byte[]) method of auAIS. - *
  5. auAIS fills the buffer with the bytes. - *
  6. pcmAIS1 calls the initFromByteArray method of - * the float buffer to initialize it with the 8 bit data. - *
  7. Then pcmAIS1 processes the data: as the float buffer is - * normalized, it does nothing with the buffer - and returns - * control to pcmAIS2. The SampleSizeInBits field of the - * AudioFormat of pcmAIS1 defines that it should be 16 bits. - *
  8. pcmAIS2 receives the filled buffer from pcmAIS1 and does - * its processing on the buffer - it adds the reverb. - *
  9. As pcmAIS2's read(byte[]) method had been called, pcmAIS2 - * calls the convertToByteArray method of - * the float buffer to fill the byte buffer with the - * resulting samples. - *
- *

- * To summarize, here are some advantages when using a FloatSampleBuffer - * for streaming: - *

    - *
  • no conversions from/to bytes need to be done during processing - *
  • the sample size in bits is irrelevant - normalized range - *
  • higher quality for processing - *
  • separated channels (easy process/remove/add channels) - *
  • potentially less copying of audio data, as processing - * the float samples is generally done in-place. The same - * instance of a FloatSampleBuffer may be used from the original data source - * to the final data sink. - *
- *

- * Simple benchmarks showed that the processing requirements - * for the conversion to and from float is about the same as - * when converting it to shorts or ints without dithering, - * and significantly higher with dithering. An own implementation - * of a random number generator may improve this. - *

- * "Lazy" deletion of samples and channels:
- *

    - *
  • When the sample count is reduced, the arrays are not resized, but - * only the member variable sampleCount is reduced. A subsequent - * increase of the sample count (which will occur frequently), will check - * that and eventually reuse the existing array. - *
  • When a channel is deleted, it is not removed from memory but only - * hidden. Subsequent insertions of a channel will check whether a hidden channel - * can be reused. - *
- * The lazy mechanism can save many array instantiation (and copy-) operations - * for the sake of performance. All relevant methods exist in a second - * version which allows explicitely to disable lazy deletion. - *

- * Use the reset functions to clear the memory and remove - * hidden samples and channels. - *

- * Note that the lazy mechanism implies that the arrays returned - * from getChannel(int) may have a greater size - * than getSampleCount(). Consequently, be sure to never rely on the - * length field of the sample arrays. - *

- * As an example, consider a chain of converters that all act - * on the same instance of FloatSampleBuffer. Some converters - * may decrease the sample count (e.g. sample rate converter) and - * delete channels (e.g. PCM2PCM converter). So, processing of one - * block will decrease both. For the next block, all starts - * from the beginning. With the lazy mechanism, all float arrays - * are only created once for processing all blocks.
- * Having lazy disabled would require for each chunk that is processed - *

    - *
  1. new instantiation of all channel arrays - * at the converter chain beginning as they have been - * either deleted or decreased in size during processing of the - * previous chunk, and - *
  2. re-instantiation of all channel arrays for - * the reduction of the sample count. - *
- *

- * Dithering:
- * By default, this class uses dithering for reduction - * of sample width (e.g. original data was 16bit, target - * data is 8bit). As dithering may be needed in other cases - * (especially when the float samples are processed using DSP - * algorithms), or it is preferred to switch it off, - * dithering can be explicitely switched on or off with - * the method setDitherMode(int).
- * For a discussion about dithering, see - * - * here and - * - * here. - * - * @author Florian Bomers - */ - -public class FloatSampleBuffer { - - /** Whether the functions without lazy parameter are lazy or not. */ - private static final boolean LAZY_DEFAULT=true; - - private ArrayList channels = new ArrayList(); // contains for each channel a float array - private int sampleCount=0; - private int channelCount=0; - private float sampleRate=0; - private int originalFormatType=0; - - /** Constant for setDitherMode: dithering will be enabled if sample size is decreased */ - public static final int DITHER_MODE_AUTOMATIC=0; - /** Constant for setDitherMode: dithering will be done */ - public static final int DITHER_MODE_ON=1; - /** Constant for setDitherMode: dithering will not be done */ - public static final int DITHER_MODE_OFF=2; - - private float ditherBits = FloatSampleTools.DEFAULT_DITHER_BITS; - - // e.g. the sample rate converter may want to force dithering - private int ditherMode = DITHER_MODE_AUTOMATIC; - - //////////////////////////////// initialization ///////////////////////////////// - - /** - * Create an instance with initially no channels. - */ - public FloatSampleBuffer() { - this(0,0,1); - } - - /** - * Create an empty FloatSampleBuffer with the specified number of channels, - * samples, and the specified sample rate. - */ - public FloatSampleBuffer(int channelCount, int sampleCount, float sampleRate) { - init(channelCount, sampleCount, sampleRate, LAZY_DEFAULT); - } - - /** - * Creates a new instance of FloatSampleBuffer and initializes - * it with audio data given in the interleaved byte array buffer. - */ - public FloatSampleBuffer(byte[] buffer, int offset, int byteCount, - AudioFormat format) { - this(format.getChannels(), - byteCount/(format.getSampleSizeInBits()/8*format.getChannels()), - format.getSampleRate()); - initFromByteArray(buffer, offset, byteCount, format); - } - - protected void init(int channelCount, int sampleCount, float sampleRate) { - init(channelCount, sampleCount, sampleRate, LAZY_DEFAULT); - } - - protected void init(int channelCount, int sampleCount, float sampleRate, boolean lazy) { - if (channelCount<0 || sampleCount<0) { - throw new IllegalArgumentException( - "invalid parameters in initialization of FloatSampleBuffer."); - } - setSampleRate(sampleRate); - if (getSampleCount()!=sampleCount || getChannelCount()!=channelCount) { - createChannels(channelCount, sampleCount, lazy); - } - } - - private void createChannels(int channelCount, int sampleCount, boolean lazy) { - this.sampleCount=sampleCount; - // lazy delete of all channels.
