Detailed Description

File copying with conversion.

spr_copy [-A](flag: ASCII) [-H](flag: HEADER) [-HL](flag: HEADER_LEN) [-i ifname](stdin)
    [-o ofname](stdout) [-t type] [-f firstframe:lastframe] [-c firstchannel:lastchannel]
    [-p firstparam:lastparam] [-l length](-1) (-Fd==-t)

Parameters

-Aflag	ASCII Produce an output file in ASCII format.
-Hflag	HEADER Dump the header; do not copy data.
-HLflag	HEADER_LEN Add the key HEADER_LEN to the header; useful for programs that just want to skip the header.
-i<em>ifname</em><a	name="spr_copy.i" class="el"> Input file name.
-o<em>ofname</em><a	name="spr_copy.o" class="el"> Output file name.
-t<em>type</em><a	name="spr_copy.t" class="el"> Data type to use for the output. Possibilities are: [UI](8\|16\|32\|64) for unsigned/signed 8/16/32/64 bits integers, F(32\|64) for single/double precision floats, or ULAW/ALAW for u-law/a-law encoding.
-f<em>firstframe:lastframe</em><a	name="spr_copy.f" class="el"> Select these specific frames (normally all frames are used).
-c<em>firstchannel:lastchannel</em><a	name="spr_copy.c" class="el"> This option only applies to SAMPLE files. Select channels in a multichannel data file, default is all channels.
-p<em>firstparam:lastparam</em><a	name="spr_copy.p" class="el"> This option only applies to TRACK or PARAM files. Select parameters in a track data file, default is all parameters.
-l<em>length</em><a	name="spr_copy.l" class="el"> Frame length for sampled data; by default the value of FSHIFT or if not available FLENGTH, or if not available the default value (0.01) is used.

File copying with conversion. This program performs general purpose copy and conversion actions.

Depending on the content of the file, spr_copy can

convert the header to the SPRAAK format and simply copy the remainder of the data; supported for all files
copy only a certain fields and entries; supported on files containing lists of strings such as corpus files and dictionaries
copy a selection of frames (rows) and parameters (columns) only; supported on all files which store their data in a simple MATRIX layout, e.g. track and some parameter files
copy a selection of frames and audio channels only; supported on sample files only

Note: files such as .hmm and .sel which store variable length and/or sparse data superimpose is simple matrix (single column vector) layout on top of the real data layout. This assures that basic operations like "spr_copy -A" for viewing the raw content still work. However, selecting data from such a file will break the real data layout and will result in a corrupted file.

Revision History:

8 Sep 1991 - Dirk Van Compernolle: implementation of original version
3 Mar 1994 - Frank Schoeters: added test on requested number of data to copy to prevent array access to reach out of bounds.
8 Dec 1994 - Frank Schoeters: added the options `S' and `nchan' to allow specifying the sample frequency and the number of channels.
1 Jun 2008 - KD: reimplementation for SPRAAK
