<LI><A NAME="def_STREAMINFO"><B>STREAMINFO</B>: This block has information about the whole stream, like sample rate, number of channels, total number of samples, etc. It must be present as the first metadata block in the stream. Other metadata blocks may follow, and ones that the decoder doesn't understand, it will skip.</LI>
<LI><A NAME="def_APPLICATION"><B>APPLICATION</B>: This block is for use by third-party applications. The only mandatory field is a 32-bit identifier. This ID is granted upon request to an application by the FLAC maintainers. The remainder is of the block is defined by the registered application. Visit the <A HREF="id.html">registration page</A> if you would like to register an ID for your application with FLAC.</LI>
<LI><A NAME="def_PADDING"><B>PADDING</B>: This block allows for an arbitrary amount of padding. The contents of a PADDING block have no meaning. This block is useful when it is known that an APPLICATION block will be added after encoding; the user can instruct the encoder to reserve a PADDING block of the proper size so that the application may directly write over it later (which is relatively quick) instead of having to insert the APPLICATION block (which would normally require rewriting the entire file).</LI>
<LI><A NAME="def_PADDING"><B>PADDING</B>: This block allows for an arbitrary amount of padding. The contents of a PADDING block have no meaning. This block is useful when it is known that metadata will be edited after encoding; the user can instruct the encoder to reserve a PADDING block of sufficient size so that when metadata is added, it will simply overwrite the padding (which is relatively quick) instead of having to insert it into the right place in the existing file (which would normally require rewriting the entire file).</LI>
<LI><A NAME="def_SEEKTABLE"><B>SEEKTABLE</B>: This is an optional block for storing seek points. It is possible to seek to any given sample in a FLAC stream without a seek table, but the delay can be unpredictable since the bitrate may vary widely within a stream. By adding seek points to a stream, this delay can be significantly reduced. Each seek point takes 18 bytes, so 1% resolution within a stream adds less than 2k. There can be only one SEEKTABLE in a stream, but the table can have any number of seek points. There is also a special 'placeholder' seekpoint which will be ignored by decoders but which can be used to reserve space for future seek point insertion.</LI>
<LI><A NAME="def_VORBIS_COMMENT"><B>VORBIS_COMMENT</B>: This block is for storing a list of human-readable name/value pairs. Values are encoded using UTF-8. It is an implementation of the <A HREF="http://xiph.org/ogg/vorbis/doc/v-comment.html">Vorbis comment specification</A>. This is the only officially supported tagging mechanism in FLAC. There may be only one VORBIS_COMMENT block in a stream.</LI>
<LI><A NAME="def_CUESHEET"><B>CUESHEET</B>: This block is for storing various information that can be used in a cue sheet. It supports track and index points, compatible with Red Book CD digital audio discs, as well as other CD-DA metadata such as media catalog number and track ISRCs. The CUESHEET block is especially useful for backing up CD-DA discs, but it can be used as a general purpose cueing mechanism for playback.</LI>
