These methods give you an object (an AudioInputStream) that lets you read the file's audio data, using one of the read methods of AudioInputStream. Static AudioInputStream getAudioInputStream (java.io.InputStream stream) Static AudioInputStream getAudioInputStream ( url) Static AudioInputStream getAudioInputStream (java.io.File file) This page, which is divided into three sections, explains these three kinds of activity. The AudioSystem class provides methods for (1) storing a stream of audio data from an AudioInputStream into an audio file of a particular type (in other words, writing a file), (2) extracting a stream of audio bytes (an AudioInputStream) from an audio file (in other words, reading a file), and (3) converting audio data from one data format to another.The AudioFileFormat includes an AudioFormat object to describe the format of the audio data stored in the file, and also includes information about the file type and the length of the data in the file. A sound file format is represented in the Java Sound API by an AudioFileFormat object. The different types of sound file have different structures for storing audio data as well as for storing descriptive information about the audio data. There are several well-known, standard formats for sound files, such as WAV, AIFF, or AU.An AudioFormat includes such information as the encoding, the byte order, the number of channels, the sampling rate, and the number of bits per sample. In other words, an AudioFormat describes "raw" audio data, such as the system might hand your program after capturing it from a microphone input or after parsing it from a sound file. This format specifies how the audio samples themselves are arranged, but not the structure of a file that they might be stored in. The format of this audio data is represented by an AudioFormat object.( AudioInputStream inherits from java.io.InputStream.) A stream of audio data, as might be read from or written to a file, is represented by an AudioInputStream object.Overview of the Sampled Package introduced the main classes related to sound files and audio data formats. Application programs can read, write, and translate between a variety of sound file formats and audio data formats. In some cases, the data that has been read (or that will be written) needs to be converted to a different format.Īccessing Audio System Resources, the Java Sound API provides application developers with various facilities for file input/output and format translations.
Similarly, many programs need to write sound files (or streams).
This is common functionality, regardless of what the program may subsequently do with the data it reads (such as play, mix, or process it). Most application programs that deal with sound need to read sound files or audio streams.
