          throws IOException

Loads a Speex File from the given packet reader.

Throws:

IOException

SpeexFile

public SpeexFile(OutputStream out)

Opens for writing.

SpeexFile

public SpeexFile(OutputStream out,
                 SpeexInfo info,
                 SpeexTags tags)

Opens for writing, based on the settings from a pre-read file. The Steam ID (SID) is automatically allocated for you.

SpeexFile

public SpeexFile(OutputStream out,
                 int sid,
                 SpeexInfo info,
                 SpeexTags tags)

Opens for writing, based on the settings from a pre-read file, with a specific Steam ID (SID). You should only set the SID when copying one file to another!

Method Detail

getNextAudioPacket

public SpeexAudioData getNextAudioPacket()
                                  throws IOException

Description copied from interface: OggAudioStream

Returns the next OggStreamAudioData packet in the stream, or null if no more remain

Specified by:

getNextAudioPacket in interface OggAudioStream

Throws:

IOException

skipToGranule

public void skipToGranule(long granulePosition)
                   throws IOException

Skips the audio data to the next packet with a granule of at least the given granule position. Note that skipping backwards is not currently supported!

Specified by:

skipToGranule in interface OggAudioStream

Throws:

IOException

getSid

public int getSid()

Returns the Ogg Stream ID

Specified by:

getSid in interface OggAudioHeaders

Returns:

The stream id of the overall audio stream

getType

public OggStreamIdentifier.OggStreamType getType()

This is a Speex file

Specified by:

getType in interface OggAudioHeaders

Returns:

The type of the audio stream

getInfo

public SpeexInfo getInfo()

Specified by:

getInfo in interface OggAudioHeaders

Returns:

The information / identification of the stream and audio encoding

getTags

public SpeexTags getTags()

Specified by:

getTags in interface OggAudioHeaders

Returns:

The Tags / Comments describing the stream

getSetup

public OggAudioSetupHeader getSetup()

Speex doesn't have setup headers, so this is always null

Specified by:

getSetup in interface OggAudioHeaders

Returns:

The Setup information for the audio encoding, if used in the format

writeAudioData

public void writeAudioData(SpeexAudioData data)

Buffers the given audio ready for writing out. Data won't be written out yet, you need to call close() to do that, because we assume you'll still be populating the Info/Comment/Setup objects

close

public void close()
           throws IOException

In Reading mode, will close the underlying ogg file and free its resources. In Writing mode, will write out the Info and Tags objects, and then the audio data.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

IOException

getOggFile

public OggFile getOggFile()

Returns the underlying Ogg File instance

Returns:
