NAME
====
-fdkaac - command line frontend for libfdk-aac encoder
+fdkaac - command line frontend for libfdk-aac encoder
SYNOPSIS
========
If the input file is "-", data is read from stdin. Likewise, if the
output file is "-", data is written to stdout if one of streamable AAC
-transport formats is selected by **-f**.
+transport formats are selected by **-f**.
When CAF input and M4A output is used, tags in CAF file are copied into
-the resulting M4A.
+the resulting M4A.

EXAMPLES
========
Upto 32bit integer or 64bit floating point format is supported as input.
However, FDK library is implemented based on fixed point math and only
-supports 16bit integer PCM. Therefore, be careful of clipping. You might
+supports 16bit integer PCM. Therefore, be wary of clipping. You might
want to dither/noise shape beforehand when your input has higher
resolution.
