L
are:
inear Linearly encoded data with a fixed number of bits per sample. This is the default
I
encoding. The number of bits per sample can be set using the -p option.
EEE IEEE floating-point encoding with 4 bytes/sample.
–f format
help List available encodings.
Specify format of digital audio data in file. If this option is not given, then naplay will use
r
heuristics to guess the type of each file to played back. The following formats are currently
ecognized:
raw In this format, sampled data is stored as consecutive 16 bit words with most
a
significant byte first. If stereo output is requested, the left and right channel data
re interleaved on a word-by-word basis, with the left channel occurring first. This
n
is the default format for files which do not have a header.
ative This format is similar to raw except that the byte-ordering is the standard byte-
-
a
order used on the machine. Files created using the native format will not be port
ble to machines with different byte-order.
.
A
swap The byte-ordering in this format is the reverse of the raw format
IFF Audio interchange file format. Both AIFF and AIFF-C files can be read using this
s
format.
ppack This format uses AT&T Bell Laboratories SPPACK format.
dSPW3 This format allows files created with Comdisco’s SPW system revisions 3.0 an
later to be played.
SPW2 This format allows files created with Comdisco’s SPW system revisions 2.8 and
E
earlier to be played.
SPS This format allows Entropic ESPS/waves+ to be read. Files with NIST SPHERE
a
headers can also be read using this option. ESPS must be installed on the system
nd the DAT-Link software installed with the Entropic option to enable this for-
h
mat.
elp Lists available formats.
–o channels
Channels can be one of left, right, mono or stereo. For the first three the data file is inter-
-
n
preted as single channel data and is played back to either the left, right, or both output chan
els. If stereo is given, then the data file is assume to contain interleaved data for two chan-
c
nels with the left channel first. The default is stereo unless the first file on the command line
ontains a header which identifies the data as mono.
–p precision
Specify the number of bits/sample to be transferred to the DAT-Link. This option can only be
–r range
used if the encoding is linear (See the -e option). The default precision is 16 bits/sample.
Select a subrange of points to be played from each file, using the format start–end , start:end
e
fi
or start:+count. Either the start or the end may be omitted; the beginning or the end of th
le are used if no alternative is specified.
–R repeats
Repeat the passage repeats times with no intervening silence. If multiple files are specified on
e
e
the command line, then all the files will be played consecutively followed by repetitions of th
ntire set.
