NAME
sndfile-palette File: sndfile-palette.lsp Class Hierarchy: named-object -> linked-named-object -> sclist -> circular-sclist -> assoc-list -> recursive-assoc-list -> palette -> sndfile-palette Version: 1.0.0-beta1 Project: slippery chicken (algorithmic composition) Purpose: Implementation of the sndfile-palette class, which is a simple palette that checks that all the sound files given in a list for each id exist. See comments in methods for limitations and special features of this class.

sndfile-palette/find-sndfile [ Methods ]
[ Top ] [ sndfile-palette ] [ Methods ]
FUNCTION
Return the full directory path and file name of a specified sound file, from within the directories given in the PATHS slot.
ARGUMENTS
- A sndfile-palette object. - The name of a sound file from within that object. This can be a string or a symbol. Unless it is given as a string, it will be handled as a symbol and will be converted to lowercase. Inclusion of the file extension is optional.
RETURN VALUE
Returns the full directory path and file name of the specified sound file as a string.
EXAMPLE
(let ((msfp (make-sfp 'sfp-test '((sndfile-group-1 (test-sndfile-1)) (sndfile-group-2 (test-sndfile-2 test-sndfile-3 (test-sndfile-4 :frequency 261.61))) (sndfile-group-3 ((test-sndfile-5 :start 0.006 :end 0.182) test-sndfile-6))) :paths '("/path/to/sndfiles-dir-1" "/path/to/sndfiles-dir-2")))) (find-sndfile msfp 'test-sndfile-4)) => "/path/to/sndfiles-dir-2/test-sndfile-4.aiff"
SYNOPSIS
(defmethod find-sndfile ((sfp sndfile-palette) sndfile)
sndfile-palette/make-sfp [ Functions ]
[ Top ] [ sndfile-palette ] [ Functions ]
FUNCTION
Make a sndfile-palette object. This object is a simple palette which checks to make sure that all of the sound files in a given list exist for each given ID. Sound files are given as as single names, without the path and without the extension. These can be given using the optional keyword arguments <paths> and <extensions>.
ARGUMENTS
- An ID for the palette. - A list of lists that contains IDs for the names of one or more groups of sound files, each paired with a list of one or more names of existing sound files. The sound file names themselves can be paired with keywords from the sndfile class, such as :start, :end, and :frequency, to define and describe segments of a given sound file.
OPTIONAL ARGUMENTS
keyword arguments: - :paths. A list of one or more paths to where the sound files are located. - :extensions. A list of one or more sound file extensions for the specified sound files. The default initialization for this slot of the sndfile-palette already contains ("wav" "aiff" "aif" "snd"), so this argument can often be left unspecified. - :warn-not-found. T or NIL to indicate whether a warning should be printed to the Lisp listener if the specified sound file cannot be found. T = print warning. Default = T.
RETURN VALUE
Returns NIL.
EXAMPLE
(let ((msfp (make-sfp 'sfp-test '((sndfile-group-1 (test-sndfile-1)) (sndfile-group-2 (test-sndfile-2 test-sndfile-3 (test-sndfile-4 :frequency 261.61))) (sndfile-group-3 ((test-sndfile-5 :start 0.006 :end 0.182) test-sndfile-6))) :paths '("/path/to/sound-files-dir-1/" "/path/to/sound-files-dir-2/")))))

(defun make-sfp (id sfp &key paths extensions (warn-not-found t))

[ Top ] [ sndfile-palette ] [ Functions ]
FUNCTION
This creates a sndfile-palette with automatic groups with <snds-per-group> snds in each auto group and random groups every <random-every>. marker-file could be a list of marker files; they would be concatenated. NB Beware that marker files created on different operating systems from the one one which this function is called might trigger errors due to newline character mismatches.
