- Just updated man page of gigdump.

1 .TH "gigdump" "1" "21 Sep 2016" "libgig @VERSION@" "libgig tools"
3 gigdump \- List informations about a Gigasampler (.gig) file.
5 .B gigdump
8 By default it prints out a list of all available samples, real-time instrument
9 scripts and instruments within a Gigasampler (.gig) file, along with detailed
10 informations about their properties and settings.
12 .TP
14 filename of the Gigasampler file
15 .TP
16 .B \ --rebuild-checksums
17 Rebuild checksum table for all samples. Read description of
18 .B --verify
19 option for more details about sample checksums in general. Usually you only
20 need to use
21 .B --rebuild-checksums
22 in case the samples' CRC checksum table itself was damaged. The
23 .B --verify
24 option will tell you if that is really the case and will suggest to you to use
25 .B --rebuild-checksums
26 to repair the table in such cases. If only individual samples were damaged, you
27 rather might want to replace only those damaged samples with
28 .BR gigedit (1)
29 for example. Read description of
30 .B --verify
31 for reasons to do so. When using
32 .B --rebuild-checksums
33 all checksums of all samples will be regenerated. Hence you should manually
34 check all samples once after using this option. That is by using your ears,
35 or by exporting the samples, but not by using the
36 .B --verify
37 option. Because the latter cannot identifiy damaged samples that have been
38 damaged before the entire checksum table had been regenerated.
39 .TP
40 .B \ -v
41 Print version and exit.
42 .TP
43 .B \ --verify
44 Check raw wave data integrity of all samples and print result of this check.
45 For all samples of a gig file a correspondig CRC32 checksum is stored along
46 to its raw wave form data whenever a conscious change to the wave form data
47 was performed. By calling gigdump with this option all samples are scanned
48 and compared with their existing checksums to detect any damage to
49 individual samples. The individual damaged samples are listed by gigdump
50 in this case. Since essentially the entire file has to be read, this can
51 take a long time and hence this check is not by default performed i.e.
52 each time a gig file is loaded for regular use for example. Accordingly you
53 may use
54 .B --verify
55 from time to time to check explicitly whether your gig files have been
56 damaged for some reason, i.e. after modifying them with an instrument editor
57 like
58 .BR gigedit (1).
59 In case damaged samples were found, you may replace those damaged samples with
60 .BR gigedit (1).
61 By doing this, only the replaced samples' checksums will be
62 updated. All other checksums remain untouched. That's why this approach is
63 recommended over using
64 .B --rebuild-checksums
65 in such cases.
