In-Depth Information
Experiment with different combinations of sample rate and bit depth to explore
the outcomes. For our portfolio, let's shoot for a small clip with high quality (22/
16). The small size will help performance. We can loop the clip in Flash if
needed.
In the Edit>Convert Sample Type dialog box, choose 22,050 for sample
rate and 16 bit resolution. Set to Mono for voice files and Stereo for music
files.
You may be worried that this may lag when loading Flash objects with the audio
embedded in the file. However, Flash has easy compression options that allow
us to change the sample rate and bit depth as well as the export format of the
audio file before using it in a Flash movie.
Then go to File>Save As and save the file as a WAV or an AIF within your
RAW folder in the root directory. MP3 file format can also be used when
saving audio for Flash. For most Web projects, WAV and AIF work best. You
can optimize the sound file to MP3 after the file is imported into Flash if
additional compression is needed.
Placing Audio in Flash
Audio files are external files. So are bitmaps and vector files. They all come into
Flash the same way, through File>Import. The import menu command has
three different options. First is File>Import>Import to stage. This command
will allow you to import external files directly to the stage. Once imported, the
file is automatically added to the library of the resident Flash file. If the imported
file is deleted from the stage, the file still remains in the library and can be used
repeatedly. The next menu command is File>Import>Import to Library.
This command brings the file directly into the library, bypassing placement on
the stage. This command is effective when you are beginning your Flash movie
and need to gather your assets into Flash. If all the files were imported to the
stage it may get confusing sorting through them all. You would need to delete
most of them from the stage in order to get some structure. The final import
choice is File>Import>Open External Library. When choosing a library file,
simply click on the FLA file and only the file's library will open. This menu
command allows you to use library file of other flash movies current movie. All
symbols and assets in the library can be dragged into your current movie. You
can mix symbols in movies easily. This provides some production shortcuts for
