Pushed v1.58 code (mega-commit again, sorry) - Added support for loading FLAC samples - The IFF sample saver was writing somewhat broken files for non-looped samples - The "UPSAMP" button in Edit Op. was showing the wrong status text - Small code refactor for how the song is timed/ticked. Longer song-to-WAV renders may have a filesize change of a few bytes, but this is actually more correct. - Increased number of precision bits for song BPM, playback time counter and audio->video syncing. This is a minor change and does very little in practice as the previous precision was already quite good. - Audio/video sync timestamps are reset every half an hour to prevent possible sync drifting after several hours of playing a song without a single song stop (resets timestamp) in-between - The HPC timers are reset every half an hour instead of every hour. The video (if no vsync) and the scopes use these timers. This hopefully fixes potential timing drifting issues that were still lingering. - Code refactoring for module/sample loaders - Windows/macOS: Updated SDL to v2.26.5

+ * \brief
+ * This module defines the structures for describing I/O callbacks
+ * to the other FLAC interfaces.
+ *
+ * The purpose of the I/O callback functions is to create a common way
+ * for the metadata interfaces to handle I/O.
+ *
+ * Originally the metadata interfaces required filenames as the way of
+ * specifying FLAC files to operate on. This is problematic in some
+ * environments so there is an additional option to specify a set of
+ * callbacks for doing I/O on the FLAC file, instead of the filename.
+ *
+ * In addition to the callbacks, a FLAC__IOHandle type is defined as an
+ * opaque structure for a data source.
+ *
+ * The callback function prototypes are similar (but not identical) to the
+ * stdio functions fread, fwrite, fseek, ftell, feof, and fclose. If you use
+ * stdio streams to implement the callbacks, you can pass fread, fwrite, and
+ * fclose anywhere a FLAC__IOCallback_Read, FLAC__IOCallback_Write, or
+ * FLAC__IOCallback_Close is required, and a FILE* anywhere a FLAC__IOHandle
+ * is required. \warning You generally CANNOT directly use fseek or ftell
+ * for FLAC__IOCallback_Seek or FLAC__IOCallback_Tell since on most systems
+ * these use 32-bit offsets and FLAC requires 64-bit offsets to deal with
+ * large files. You will have to find an equivalent function (e.g. ftello),
+ * or write a wrapper. The same is true for feof() since this is usually
+ * implemented as a macro, not as a function whose address can be taken.

+ *
+ * \brief
+ * This module contains structure definitions for the representation
+ * of FLAC format components in memory. These are the basic
+ * structures used by the rest of the interfaces.
+ *
+ * First, you should be familiar with the
+ * <A HREF="../format.html">FLAC format</A>. Many of the values here
+ * follow directly from the specification. As a user of libFLAC, the
+ * interesting parts really are the structures that describe the frame
+ * header and metadata blocks.
+ *
+ * The format structures here are very primitive, designed to store
+ * information in an efficient way. Reading information from the
+ * structures is easy but creating or modifying them directly is
+ * more complex. For the most part, as a user of a library, editing
+ * is not necessary; however, for metadata blocks it is, so there are
+ * convenience functions provided in the \link flac_metadata metadata
+ * module \endlink to simplify the manipulation of metadata blocks.
+ *
+ * \note
+ * It's not the best convention, but symbols ending in _LEN are in bits
+ * and _LENGTH are in bytes. _LENGTH symbols are \#defines instead of
+ * global variables because they are usually used when declaring byte
+ * arrays and some compilers require compile-time knowledge of array
+ * sizes when declared on the stack.
+ *
+ * \{+ */

+ * \ingroup flac
+ *
+ * \brief
+ * This module provides functions for creating and manipulating FLAC
+ * metadata blocks in memory, and three progressively more powerful
+ * interfaces for traversing and editing metadata in native FLAC files.
+ * Note that currently only the Chain interface (level 2) supports Ogg
+ * FLAC files, and it is read-only i.e. no writing back changed
+ * metadata to file.
+ *
+ * There are three metadata interfaces of increasing complexity:
+ *
+ * Level 0:
+ * Read-only access to the STREAMINFO, VORBIS_COMMENT, CUESHEET, and
+ * PICTURE blocks.
+ *
+ * Level 1:
+ * Read-write access to all metadata blocks. This level is write-
+ * efficient in most cases (more on this below), and uses less memory
+ * than level 2.
+ *
+ * Level 2:
+ * Read-write access to all metadata blocks. This level is write-
+ * efficient in all cases, but uses more memory since all metadata for
+ * the whole file is read into memory and manipulated before writing
+ * out again.
+ *
+ * What do we mean by efficient? Since FLAC metadata appears at the
+ * beginning of the file, when writing metadata back to a FLAC file
+ * it is possible to grow or shrink the metadata such that the entire
+ * file must be rewritten. However, if the size remains the same during
+ * changes or PADDING blocks are utilized, only the metadata needs to be
+ * overwritten, which is much faster.
+ *
+ * Efficient means the whole file is rewritten at most one time, and only
+ * when necessary. Level 1 is not efficient only in the case that you
+ * cause more than one metadata block to grow or shrink beyond what can
+ * be accommodated by padding. In this case you should probably use level
+ * 2, which allows you to edit all the metadata for a file in memory and
+ * write it out all at once.
+ *
+ * All levels know how to skip over and not disturb an ID3v2 tag at the
+ * front of the file.
+ *
+ * All levels access files via their filenames. In addition, level 2
+ * has additional alternative read and write functions that take an I/O
+ * handle and callbacks, for situations where access by filename is not
+ * possible.
+ *
+ * In addition to the three interfaces, this module defines functions for
+ * creating and manipulating various metadata objects in memory. As we see
+ * from the Format module, FLAC metadata blocks in memory are very primitive
+ * structures for storing information in an efficient way. Reading
+ * information from the structures is easy but creating or modifying them
+ * directly is more complex. The metadata object routines here facilitate
+ * this by taking care of the consistency and memory management drudgery.
+ *
+ * Unless you will be using the level 1 or 2 interfaces to modify existing
+ * metadata however, you will not probably not need these.
+ *
+ * From a dependency standpoint, none of the encoders or decoders require
+ * the metadata module. This is so that embedded users can strip out the
+ * metadata module from libFLAC to reduce the size and complexity.

+ *
+ * \brief
+ * The level 1 interface provides read-write access to FLAC file metadata and
+ * operates directly on the FLAC file.
+ *
+ * The general usage of this interface is:
+ *
+ * - Create an iterator using FLAC__metadata_simple_iterator_new()
+ * - Attach it to a file using FLAC__metadata_simple_iterator_init() and check
+ * the exit code. Call FLAC__metadata_simple_iterator_is_writable() to
+ * see if the file is writable, or only read access is allowed.
+ * - Use FLAC__metadata_simple_iterator_next() and
+ * FLAC__metadata_simple_iterator_prev() to traverse the blocks.
+ * This is does not read the actual blocks themselves.
+ * FLAC__metadata_simple_iterator_next() is relatively fast.
+ * FLAC__metadata_simple_iterator_prev() is slower since it needs to search
+ * forward from the front of the file.
+ * - Use FLAC__metadata_simple_iterator_get_block_type() or
+ * FLAC__metadata_simple_iterator_get_block() to access the actual data at
+ * the current iterator position. The returned object is yours to modify
+ * and free.
+ * - Use FLAC__metadata_simple_iterator_set_block() to write a modified block
+ * back. You must have write permission to the original file. Make sure to
+ * read the whole comment to FLAC__metadata_simple_iterator_set_block()
+ * below.
+ * - Use FLAC__metadata_simple_iterator_insert_block_after() to add new blocks.
+ * Use the object creation functions from
+ * \link flac_metadata_object here \endlink to generate new objects.
+ * - Use FLAC__metadata_simple_iterator_delete_block() to remove the block
+ * currently referred to by the iterator, or replace it with padding.
+ * - Destroy the iterator with FLAC__metadata_simple_iterator_delete() when
+ * finished.
+ *
+ * \note
+ * The FLAC file remains open the whole time between
+ * FLAC__metadata_simple_iterator_init() and
+ * FLAC__metadata_simple_iterator_delete(), so make sure you are not altering
+ * the file during this time.
+ *
+ * \note
+ * Do not modify the \a is_last, \a length, or \a type fields of returned
+ * FLAC__StreamMetadata objects. These are managed automatically.
+ *

+ * - Create a new chain using FLAC__metadata_chain_new(). A chain is a
+ * linked list of FLAC metadata blocks.
+ * - Read all metadata into the chain from a FLAC file using

+ * - Create a new iterator using FLAC__metadata_iterator_new()
+ * - Initialize the iterator to point to the first element in the chain

+ * - Traverse the chain using FLAC__metadata_iterator_next and
+ * FLAC__metadata_iterator_prev().
+ * - Get a block for reading or modification using

+ * Make sure to read the whole comment to the function below.
+ * - Delete the chain using FLAC__metadata_chain_delete().

+ * \note
+ * Even though the FLAC file is not open while the chain is being

+ *
+ * \brief
+ * This module contains methods for manipulating FLAC metadata objects.
+ *
+ * Since many are variable length we have to be careful about the memory
+ * management. We decree that all pointers to data in the object are
+ * owned by the object and memory-managed by the object.
+ *
+ * Use the FLAC__metadata_object_new() and FLAC__metadata_object_delete()
+ * functions to create all instances. When using the
+ * FLAC__metadata_object_set_*() functions to set pointers to data, set
+ * \a copy to \c true to have the function make it's own copy of the data, or
+ * to \c false to give the object ownership of your data. In the latter case
+ * your pointer must be freeable by free() and will be free()d when the object
+ * is FLAC__metadata_object_delete()d. It is legal to pass a null pointer as
+ * the data pointer to a FLAC__metadata_object_set_*() function as long as
+ * the length argument is 0 and the \a copy argument is \c false.
+ *
+ * The FLAC__metadata_object_new() and FLAC__metadata_object_clone() function
+ * will return \c NULL in the case of a memory allocation error, otherwise a new
+ * object. The FLAC__metadata_object_set_*() functions return \c false in the
+ * case of a memory allocation error.
+ *
+ * We don't have the convenience of C++ here, so note that the library relies
+ * on you to keep the types straight. In other words, if you pass, for
+ * example, a FLAC__StreamMetadata* that represents a STREAMINFO block to
+ * FLAC__metadata_object_application_set_data(), you will get an assertion
+ * failure.
+ *
+ * For convenience the FLAC__metadata_object_vorbiscomment_*() functions
+ * maintain a trailing NUL on each Vorbis comment entry. This is not counted
+ * toward the length or stored in the stream, but it can make working with plain
+ * comments (those that don't contain embedded-NULs in the value) easier.
+ * Entries passed into these functions have trailing NULs added if missing, and
+ * returned entries are guaranteed to have a trailing NUL.
+ *
+ * The FLAC__metadata_object_vorbiscomment_*() functions that take a Vorbis
+ * comment entry/name/value will first validate that it complies with the Vorbis
+ * comment specification and return false if it does not.
+ *
+ * There is no need to recalculate the length field on metadata blocks you
+ * have modified. They will be calculated automatically before they are
+ * written back to a file.

+/** \defgroup flac_stream_decoder FLAC/stream_decoder.h: stream decoder interface
+ * \ingroup flac_decoder
+ *
+ * \brief
+ * This module contains the functions which implement the stream
+ * decoder.
+ *
+ * The stream decoder can decode native FLAC, and optionally Ogg FLAC
+ * (check FLAC_API_SUPPORTS_OGG_FLAC) streams and files.
+ *
+ * The basic usage of this decoder is as follows:
+ * - The program creates an instance of a decoder using
+ * FLAC__stream_decoder_new().
+ * - The program overrides the default settings using
+ * FLAC__stream_decoder_set_*() functions.
+ * - The program initializes the instance to validate the settings and
+ * prepare for decoding using
+ * - FLAC__stream_decoder_init_stream() or FLAC__stream_decoder_init_FILE()
+ * or FLAC__stream_decoder_init_file() for native FLAC,
+ * - FLAC__stream_decoder_init_ogg_stream() or FLAC__stream_decoder_init_ogg_FILE()
+ * or FLAC__stream_decoder_init_ogg_file() for Ogg FLAC
+ * - The program calls the FLAC__stream_decoder_process_*() functions
+ * to decode data, which subsequently calls the callbacks.
+ * - The program finishes the decoding with FLAC__stream_decoder_finish(),
+ * which flushes the input and output and resets the decoder to the
+ * uninitialized state.
+ * - The instance may be used again or deleted with
+ * FLAC__stream_decoder_delete().
+ *
+ * In more detail, the program will create a new instance by calling
+ * FLAC__stream_decoder_new(), then call FLAC__stream_decoder_set_*()
+ * functions to override the default decoder options, and call
+ * one of the FLAC__stream_decoder_init_*() functions.
+ *
+ * There are three initialization functions for native FLAC, one for
+ * setting up the decoder to decode FLAC data from the client via
+ * callbacks, and two for decoding directly from a FLAC file.
+ *
+ * For decoding via callbacks, use FLAC__stream_decoder_init_stream().
+ * You must also supply several callbacks for handling I/O. Some (like
+ * seeking) are optional, depending on the capabilities of the input.
+ *
+ * For decoding directly from a file, use FLAC__stream_decoder_init_FILE()
+ * or FLAC__stream_decoder_init_file(). Then you must only supply an open
+ * \c FILE* or filename and fewer callbacks; the decoder will handle
+ * the other callbacks internally.
+ *
+ * There are three similarly-named init functions for decoding from Ogg
+ * FLAC streams. Check \c FLAC_API_SUPPORTS_OGG_FLAC to find out if the
+ * library has been built with Ogg support.
+ *
+ * Once the decoder is initialized, your program will call one of several
+ * functions to start the decoding process:
+ *
+ * - FLAC__stream_decoder_process_single() - Tells the decoder to process at
+ * most one metadata block or audio frame and return, calling either the
+ * metadata callback or write callback, respectively, once. If the decoder
+ * loses sync it will return with only the error callback being called.
+ * - FLAC__stream_decoder_process_until_end_of_metadata() - Tells the decoder
+ * to process the stream from the current location and stop upon reaching
+ * the first audio frame. The client will get one metadata, write, or error
+ * callback per metadata block, audio frame, or sync error, respectively.
+ * - FLAC__stream_decoder_process_until_end_of_stream() - Tells the decoder
+ * to process the stream from the current location until the read callback
+ * returns FLAC__STREAM_DECODER_READ_STATUS_END_OF_STREAM or
+ * FLAC__STREAM_DECODER_READ_STATUS_ABORT. The client will get one metadata,
+ * write, or error callback per metadata block, audio frame, or sync error,
+ * respectively.
+ *
+ * When the decoder has finished decoding (normally or through an abort),
+ * the instance is finished by calling FLAC__stream_decoder_finish(), which
+ * ensures the decoder is in the correct state and frees memory. Then the
+ * instance may be deleted with FLAC__stream_decoder_delete() or initialized
+ * again to decode another stream.
+ *
+ * Seeking is exposed through the FLAC__stream_decoder_seek_absolute() method.
+ * At any point after the stream decoder has been initialized, the client can
+ * call this function to seek to an exact sample within the stream.
+ * Subsequently, the first time the write callback is called it will be
+ * passed a (possibly partial) block starting at that sample.
+ *
+ * If the client cannot seek via the callback interface provided, but still
+ * has another way of seeking, it can flush the decoder using
+ * FLAC__stream_decoder_flush() and start feeding data from the new position
+ * through the read callback.
+ *
+ * The stream decoder also provides MD5 signature checking. If this is
+ * turned on before initialization, FLAC__stream_decoder_finish() will
+ * report when the decoded MD5 signature does not match the one stored
+ * in the STREAMINFO block. MD5 checking is automatically turned off
+ * (until the next FLAC__stream_decoder_reset()) if there is no signature
+ * in the STREAMINFO block or when a seek is attempted.
+ *
+ * The FLAC__stream_decoder_set_metadata_*() functions deserve special
+ * attention. By default, the decoder only calls the metadata_callback for
+ * the STREAMINFO block. These functions allow you to tell the decoder
+ * explicitly which blocks to parse and return via the metadata_callback
+ * and/or which to skip. Use a FLAC__stream_decoder_set_metadata_respond_all(),
+ * FLAC__stream_decoder_set_metadata_ignore() ... or FLAC__stream_decoder_set_metadata_ignore_all(),
+ * FLAC__stream_decoder_set_metadata_respond() ... sequence to exactly specify
+ * which blocks to return. Remember that metadata blocks can potentially
+ * be big (for example, cover art) so filtering out the ones you don't
+ * use can reduce the memory requirements of the decoder. Also note the
+ * special forms FLAC__stream_decoder_set_metadata_respond_application(id)
+ * and FLAC__stream_decoder_set_metadata_ignore_application(id) for
+ * filtering APPLICATION blocks based on the application ID.
+ *
+ * STREAMINFO and SEEKTABLE blocks are always parsed and used internally, but
+ * they still can legally be filtered from the metadata_callback.
+ *
+ * \note
+ * The "set" functions may only be called when the decoder is in the
+ * state FLAC__STREAM_DECODER_UNINITIALIZED, i.e. after
+ * FLAC__stream_decoder_new() or FLAC__stream_decoder_finish(), but
+ * before FLAC__stream_decoder_init_*(). If this is the case they will
+ * return \c true, otherwise \c false.
+ *
+ * \note
+ * FLAC__stream_decoder_finish() resets all settings to the constructor
+ * defaults, including the callbacks.
