Description copied from class: TAudioFileReader

Get an AudioFileFormat (internal implementation). Subclasses must implement this method in a way specific to the file format they handle. Note that depending on the implementation of this method, you should or should not override getAudioInputStream(InputStream, long), too (see comment there).

Specified by:

getAudioFileFormat in class TAudioFileReader

Parameters:

inputStream - The InputStream to read from.

lFileLengthInBytes - The size of the originating file, if known. If it isn't known, AudioSystem.NOT_SPECIFIED should be passed. This value may be used for byteLength in AudioFileFormat, if this value can't be derived from the informmation in the file header.

Returns:

an AudioFileFormat instance containing information from the header of the stream passed in as inputStream.

Throws:

UnsupportedAudioFileException

IOException
