|
|
.It Fl endian Ns = Ns Cm cpu
|
|

|
|
.El
|
|
.Ss Encodings
|
|

|
|
parameter allows setting of the data encoding for the output file.
|
|
The following encodings are currently supported:
|
|
.Pp

.El
|
|
.Pp
|
|
If no encoding is specified for the output file,
|
|
.Nm
|
|
will try to use the encoding of the input file.
|
|
This will not always work as most container formats
|
|
(e.g. WAV, AIFF etc) only support a small subset of encodings
|
|
(e.g. 16 bit PCM, a-law, Vorbis etc).
