enum mpg123_enc_enum An enum over all sample types possibly known to mpg123. The values are designed as bit flags to allow bitmasking for encoding families. 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 are just for signed 16bit (and 8bit derived from that). Other formats use plain C code. All formats are in native byte order. On a little endian machine this should mean that you can just feed the MPG123_ENC_SIGNED_32 data to common 24bit hardware that ignores the lowest byte (or you could choose to do rounding with these lower bits).
