     * - fixed part (id, type, stream size, extra offset, stream offset)
     * - flags (as bitflags or in separate fields, around ~6 observed flags)
     * - samples+samples (loop+total) + size+size (roughly equal to stream size)
     * - bitrate (total sample rate)
     * - base info (sample rate, pcm bits?, channels, codec)
     * - external filename or internal filename on some platforms (earlier versions)
     * - external filename offset in the extra table (later versions)
     * - end flags?
     *
     * Type 02 (old?/new):
     * Chain, possibly to play with config (ex: type 08 (float 0.3) + 01)
     *
     * Type 03 (new), 09? (old): 
     * Chain, other way to play things? (ex: type 03 + 04)
     *
     * Type 04 (old/new), 0a (old):
     * Chain of N types, possibly to play one as random (usually N voice/sfx like
     * like death screams, but may include sequences).
     *
     * Type 05 (new), 0c (old): sequences
     * N audio segment, normally with lead-in but not lead-outs.  Sequences can reuse
     * segments (internal loops), or can be single entries (full song or leads).
     * Sequences seem to include only music or cutscenes, so even single entries can be
     * useful to parse, since the readable name would make them stand out. Format:
     * - extra offset to chain
     * - intro flag
     * - outro flag
     * - sequence count
     * - ID-like fields in the header and sequence table may point to other chains?
     *
     * Type 06 (new), 0d (old):
     * Layer header, stream divided into N equal parts in a blocked format. Format:
     * - fixed part (id, type)
     * - extra offset to layer info (sample rate, pcm bits?, channels, codec, samples)
     * - layer count
     * - sometimes total channels, bitrate, etc
     * - flags?
     * - stream size + stream offset
     * - external filename, or filename offset in the extra table
     * Layer blocks are handled separatedly as the format doesn't depend on sb's version/platform.
     * Some values may be flags/config as multiple 0x06 can point to the same layer, with different 'flags'?
     *
     * Type 07 (new), 0e (old):
     * - another chain of something (single entry?), rare.
     *
     * Type 08 (new), 0f (old):
     * - audio config? (almost all fields 0 except sometimes 1.0 float in the middle).
     * in older games may also point to the extra table, maybe equivalent to 02.
