/** 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.
