.I input.sd output.fea
.SH "DESCRIPTION"
.PP
This program accepts an ESPS SD(5\-ESPS) file
.I input.sd
and writes an ESPS FEA_SD(5\-ESPS) file
.I output.fea
containing the same sampled data.
If the value of
.I hd.sd\->nchan
in the type-specific part of the input header is 1 or greater,
it gives the number of channels\*-\c
each output record consists of that number of consecutive samples
from the input file.
A value of either 0 or 1 indicates a single-channel file.
The output data type is the same
(DOUBLE, FLOAT, LONG, SHORT, or BYTE)
as the input data type.
.PP
If
.I input.spec
is "\-", standard input is used for the input file.
If
.I output.fea
is "\-", standard output is used for the output file.
.SH "OPTIONS"
.PP
The following option is supported:
.TP 
.BI \-x " debug_level"
Positive values of
.I debug_level
cause debugging information to be printed.
The default value is 0, which suppresses the messages.
.SH "ESPS PARAMETERS"
.PP
No parameter file is read.
.SH "ESPS COMMON"
.PP
The ESPS common file is not accessed.
.SH ESPS HEADERS
The output header is a new FEA_SD file header,
with appropriate items copied from the input header.
The value of the item
.I sf
in the type-specific part of the input header
is recorded in a generic header item
.I record_freq
in the output.
The type-specific input header items
.I equip, max_value, src_sf, synt_method, scale,
.I dcrem, q_method, v_excit_method, uv_excit_method, synt_interp,
.I synt_pwr, synt_rc, synt_order, start,
and
.I nan,
except those with null values,
are saved as like-named generic header items in the output file.
(A ``null'' value is a value, such as zero, NONE, or NULL, that indicates
that an item is inapplicable.)
If
.I preemphasis
in the input header is non-NULL,
it gives rise to 3 generic header items in the output:
.I preemphasis_siz, preemphasis_zeros,
and
.I preemphasis_poles
(see
.IR add_genzfunc (3-ESPSu)).
Similarly
.I de_emp,
if non-NULL, gives rise to
.I de_emp_size, de_emp_zeros,
and
.I de_emp_poles
in the output.
Generic header items in the input file header are copied to the output header
after being renamed, if necessary, to avoid name conflicts.
As usual, the command line is added as a comment, and the header of 
.I input.sd 
is added as a source file to 
.I output.fea.
.SH "FUTURE CHANGES"
.PP

if the command line contains unrecognized options or too many or too
few file names.
