;
; This file lists defined NIST header objects, their type, and a comment 
; consisting of a brief description of the object.  Header object names
; consist of alpha-numeric characters and underscores.  Type fields consist 
; of the following:
;     -i  (integer)
;     -r  (real)
;     -s  (string)
;
; The following objects are currently implemented in the NIST_1A header
; structure:
;
database_id -s          ; database identifier
database_version -s     ; database version
utterance_id -s         ; unique utterance identifier
channel_count -i        ; number of (interleaved) channels
sample_count -i         ; number of samples (per channel)
sample_rate -i          ; sampling rate (in Hz)
sample_min -i           ; minimum sample value
sample_max -i           ; maximum sample value
sample_n_bytes -i       ; number of (8-bit) bytes per sample
sample_byte_format -s   ; sample byte order
sample_sig_bits -i      ; number of significant bits per sample
end_head                ; end of header terminator (no type or value)
