wav2gig - Create GigaStudio (.gig) file from a set of WAV files.

wav2gig [ OPTIONS ] GIG_FILE WAV_FILE_OR_DIR_1 [ WAV_FILE_OR_DIR_2 ... ]

Takes a list of wave (.wav) files and / or directories containing wave files as argument(s) and creates one new GigaStudio / GigaSampler (.gig) file for those samples.

The created GigaStudio (.gig) file will contain the given input samples. The samples' meta information (as far as available) like root note (a.k.a 'unity note'), fine tune, loop points, loop type and loop play count are automatically extracted from the input wave (.wav) files and applied accordingly.

Additionally this tool creates exactly one instrument inside the newly created GigaStudio (.gig) file and tries to automatically map the samples in a meaningful way to that instrument. As the wave (.wav) format currently does not support many of the meta information required for this particular task, this tool tries to extract the required (missing) information from the individual sample's file name for being able to map the samples accordingly. See SAMPLE NAMES below for details on the assumed naming scheme for input sample files and how to override that default naming scheme by providing custom regular expression patterns.

 GIG_FILE
GigaStudio / GigaSampler (.gig) filename to be created
 WAV_FILE_OR_DIR_1
Filename or directory containing wave (.wav) file(s)
 WAV_FILE_OR_DIR_2
Filename or directory containing wave (.wav) file(s)
 -r
Recurse through all subdirectories of provided input WAV directories.
 -f
Overwrite output GigaStudio (.gig) file in case it already exists.
 -v
Print version and exit.
 --dry-run
Scan input sample (.wav) files, but exit before creating any .gig file.
 --verbose
Increase amount of info being shown.
 --regex-name1 PATTERN
Regular expression for overriding the NAME1 part of the input sample file name scheme.

Defaults to '([^-\]+) - [^-]+ - [^-]+ - [^-]+ - [^.]+'.

 --regex-name2 PATTERN
Regular expression for overriding the NAME2 part of the input sample file name scheme.

Defaults to '[^-\]+ - ([^-]+) - [^-]+ - [^-]+ - [^.]+'.

 --regex-velocity-nr PATTERN
Regular expression for overriding the VELOCITY_NR part of the input sample file name scheme.

Defaults to '[^-\]+ - [^-]+ - ([^-]+) - [^-]+ - [^.]+'.

 --regex-note-nr PATTERN
Regular expression for overriding the NOTE_NR part of the input sample file name scheme.

Defaults to '[^-\]+ - [^-]+ - [^-]+ - ([^-]+) - [^.]+'.

 --regex-note-name PATTERN
Regular expression for overriding the NOTE_NAME part of the input sample file name scheme.

Defaults to '[^-\]+ - [^-]+ - [^-]+ - [^-]+ - ([^.]+)'.

By default this tool assumes the following input sample file naming scheme for automatically mapping samples to regions on the keyboard, as well as mapping them to velocity splits adequately:

'NAME1 - NAME2 - VELOCITY_NR - NOTE_NR - NOTE_NAME.wav'

Which are interpreted in the following way:

 NAME1
Primary name of the sample (e.g. "Violin").

This is not interpreted for sample mapping, but it will be used to assemble the final sample name inside the GigaStudio (.gig) file.

You may use --regex-name1 to override this part of the naming scheme.

 NAME2
Secondary name of the sample (e.g. "Cresc").

This is currently ignored, but might be used in future.

You may use --regex-name2 to override this part of the naming scheme.

 VELOCITY_NR
MIDI Velocity number of the sample (e.g. "18").

This informtion will be used to automatically create velocity splits.

You may use --regex-velocity-nr to override this part of the naming scheme.

 NOTE_NR
MIDI Note number of the sample (e.g. "021" for note a-1).

This informtion will be used to automatically map the sample to a region on the keyboard. The sample's root note (a.k.a. "unity note") is taken directly from the .wav file content, however if the .wav file content does not contain a root note information then  NOTE_NR is used as root note as well.

You may use --regex-note-nr to override this part of the naming scheme.

 NOTE_NAME
Note name of the sample (e.g. "a-1").

This is not interpreted for sample mapping, but it will be used to assemble the final sample name inside the GigaStudio (.gig) file.

You may use --regex-note-name to override this part of the naming scheme.

This tool utilizes the regular expressions library provided by C++ (introduced with the C++11 standard revision). Each custom regular expression (abbreviated as 'RegEx' from now on below) passed to one of the --regex-* options must contain exactly one active RegEx 'capture group' which is denoted in regular expressions by a pair of round brackets like:

(PATTERN)

So the 'capture group' marks the portion in the overall filename string that is going to be exctracted for the respective component of the filename schema. If additional RegEx group(s) are needed to build the overall RegEx pattern, then those other group(s) must be defined as 'passive groups' denoted in RegEx patterns by an additional question mark and colon like this:

(?:PATTERN)

Keep in mind that RegEx scanners behave 'greedy' by default, which means by default they try to match the longest string possible according to your defined RegEx pattern. If that's not desired then you may either override the required parts of your RegEx pattern to behave 'non-greedy' such that those parts would match for the shortest string possible instead, or alternatively consider using the RegEx 'alternation' operator, which is denoted in regular expressions by a vertical bar character like:

PATTERN1|PATTERN2|PATTERN3

The RegEx 'alternation' operator is sometimes more intuitive, because it tries to match the provided patterns strictly in order from left to right. So it would first try to match the first pattern, and only if no match with the first pattern was possible (independent of string length) it would then try to match the second pattern, and so on.
