Appendix D: TroubleshootingNote: The Dither Spectrogram option in the Display Options dialog box pertains only toCanary’s onscreen graphics and has no bearing on printing.• Gray areas on printed spectrograms seem grainy.In general, Canary has no control of the final appearance of the printed output. Canarysimply sends the image of the signal window contents directly to the printer and theMacintosh operating system and the printer software and hardware handle the actualprinting. The main determinant of printed output quality (especially grayscaleresolution) is the make and model of your printer; there is considerable variation amongprinters. If the spectrograms that your printer is producing seem grainy and inadequate,the most likely reason is that your printer is lacking. Try a different printer, you may besurprised.Opening files• Canary asks for parameters every time I open a particular sound, even though thissound has been opened in Canary before.Canary needs to save this sound in order to attach parameters to it. Be certain to savethis sound in Canary even if it has not been modified.• The file I want to open does not appear in the Open File dialog box.Canary does not recognize the file type of this file. The file type is a four-character stringthat is attached to each and every item in the Macintosh file system when the file issaved. Canary recognizes the following file types, each corresponding to a file formatthat Canary understands.FormatSoundEditMATLABTextAIFFBinaryCanaryType'FSSD''MATW''TEXT''AIFF''Bin ''CNRY'Confusion about a file’s type may arise because of the “Kind” designation displayed bythe Finder for each file. The Kind displayed for a file is based on what program createdthe file, not on the file’s format or type. (Since many programs can save files in multipleformats or types, the Kind does not necessarily tell you the file’s type. For example,SoundEdit can save files in a format called Instrument, which has a type of 'DEWF'.'DEWF' files are not readable by Canary. However, the Kind that the Finder shows forboth 'DEWF' and 'FSSD' files created by SoundEdit is “SoundEdit document”. Thus,the Finder’s Kind designation does not necessarily tell you whether or not Canary canread the file.) Although the Macintosh operating system does not provide any way foryou to determine the file type of a file directly, some third-party utility programs (e.g.,DiskTop) allow you to do so. Also, most application programs use different Finder icons224 Canary 1.2 User’s Manual
