-/** An enum over all sample types possibly known to mpg123.
- *  The values are designed as bit flags to allow bitmasking for encoding
- *  families.
- *  This is also why the enum is not used as type for actual encoding variables,
- *  plain integers (at least 16 bit, 15 bit being used) cover the possible
- *  combinations of these flags.
- *
- *  Note that (your build of) libmpg123 does not necessarily support all these.
- *  Usually, you can expect the 8bit encodings and signed 16 bit.
- *  Also 32bit float will be usual beginning with mpg123-1.7.0 .
- *  What you should bear in mind is that (SSE, etc) optimized routines may be
- *  absent for some formats. We do have SSE for 16, 32 bit and float, though.
- *  24 bit integer is done via postprocessing of 32 bit output -- just cutting
- *  the last byte, no rounding, even. If you want better, do it yourself.
- *
- *  All formats are in native byte order. If you need different endinaness, you
- *  can simply postprocess the output buffers (libmpg123 wouldn't do anything
- * else). The macro MPG123_SAMPLESIZE() can be helpful there.
