Java Sound Programmer Guide

Introductory Material

Preface For Whom This Guide Is Intended What this Guide Describes For More Information Chapter: 1 Introduction to the Java Sound API Design Goals Who is the Java Sound API For? How Does the Java Sound API Relate to Other Interfaces? Packages Sampled Audio What Is Sampled Audio? Audio Configurations MIDI What Is MIDI? MIDI Configurations Service Provider Interfaces

 

Part I: Sampled Audio

 

Chapter 2: Overview of the Sampled Package Design Goals A Focus on Data Transport Buffered and Unbuffered Handling of Audio The Essentials: Format, Mixer, and Line What Is Formatted Audio Data? What Is a Mixer? What Is a Line? Lines in an Audio-output Configuration Lines in an Audio-input Configuration The Line Interface Hierarchy Chapter 3: Accessing Audio System Resources The AudioSystem Class Information Objects Getting a Mixer Getting a Line of a Desired Type Getting a Line Directly from the AudioSystem Getting a Line from a Mixer Selecting Input and Output Ports Permission to Use Audio Resources Chapter 4: Playing Back Audio Using a Clip Setting Up the Clip for Playback Starting and Stopping Playback Using a SourceDataLine Setting Up the SourceDataLine for Playback Starting and Stopping Playback Monitoring a Line's Status Synchronizing Playback on Multiple Lines Processing the Outgoing Audio Chapter 5: Capturing Audio Setting Up a TargetDataLine Reading the Data from the TargetDataLine Monitoring the Line's Status Processing the Incoming Audio Chapter 6: Processing Audio with Controls Introduction to Controls Getting a Line that Has the Desired Controls Getting the Controls from the Line Using a Control to Change the Audio Signal Controlling a Line's Mute State Changing a Line's Volume Selecting among Various Reverberation Presets Manipulating the Audio Data Directly Chapter 7: Using Files and Format Converters Reading Sound Files Writing Sound Files Converting File and Data Formats Converting from One File Format to Another Converting Audio between Different Data Formats Learning What Conversions Are Available

 

Part II: MIDI

 

Chapter 8: Overview of the MIDI Package A MIDI Refresher: Wires and Files Streaming Data in the MIDI Wire Protocol Sequenced Data in Standard MIDI Files The Java Sound API's Representation of MIDI Data MIDI Messages MIDI Events Sequences and Tracks The Java Sound API's Representation of MIDI Devices The MidiDevice Interface Transmitters and Receivers Sequencers Synthesizers Chapter 9: Accessing MIDI System Resources The MidiSystem Class Obtaining Default Devices Learning What Devices Are Installed Obtaining a Desired Device Opening Devices Chapter 10: Transmitting and Receiving MIDI Messages Understanding Devices, Transmitters, and Receivers Sending a Message to a Receiver without Using a Transmitter Understanding Time Stamps Time Stamps on Messages Sent to Devices Connecting Transmitters to Receivers Connecting to a Single Device Connecting to More than One Device Closing Connections Chapter 11: Playing, Recording, and Editing MIDI Sequences Introduction to Sequencers When to Use a Sequencer Understanding Sequence Data Sequences and Tracks MidiEvents and Ticks Overview of Sequencer Methods Obtaining a Sequencer Loading a Sequence Playing a Sequence Recording and Saving Sequences Editing a Sequence Using Advanced Sequencer Features Moving to an Arbitrary Position in the Sequence Changing the Playback Speed Muting or Soloing Individual Tracks in the Sequence Synchronizing with Other MIDI Devices Specifying Special Event Listeners Chapter 12: Synthesizing Sound Understanding MIDI Synthesis Instruments Channels Soundbanks and Patches Voices Managing Instruments and Soundbanks Learning What Instruments Are Loaded Loading Different Instruments Unloading Instruments Accessing Soundbank Resources Querying the Synthesizer's Capabilities and Current State Using Channels Controlling the Synthesizer without Using a Sequencer Getting a Channel's Current State Muting and Soloing a Channel Permission to Play Synthesized Sound

 

Part III: Service Provider Interfaces

 

Chapter 13: Introduction to the Service Provider Interfaces What Are Services? How Services Work How Providers Prepare New Services How Users Install New Services Chapter 14: Providing Sampled-Audio Services Introduction Providing Audio File-Writing Services Providing Audio File-Reading Services Providing Format-Conversion Services Providing New Types of Mixers Chapter 15: Providing MIDI Services Introduction Providing MIDI File-Writing Services Providing MIDI File-Reading Services Providing Particular MIDI Devices Providing Soundbank File-Reading Services
