RE: FLASH: Audio compression

[Dave Hollinden]

In Flash 3, select the sound file from the Library, set the sampling rate to

22kHz and the ADPCM compression to 4 bits, then hit Test to hear the sound

quality and see the size of the exported sound file.  If it sounds OK and is

small enough, you're set.  If it's too big, drop it to 3 bits and Test it

again.  If still too big, drop the sampling frequency to 11kHz and Test it

again.  Keep playing with smaller values of sampling frequency and number of

bits to get an acceptable sound and size.


These values, since they are set for the individual file, will override the

default settings for the rest of your sound files in the main export dialog

box unless you click the Override Settings checkbox.  This is great because

you can individually set the export parameters for each  sound file much the

same way that you can set the export quality of bitmaps.

Subject: FLASH: Audio compression



Audio question: What is the best way to compress audio in flash 3 for a

small background loop. I would like to use a detection script to send users

to a Flash 3 version of a movie rather than force them to upgrade to Flash

4. The Flash 3 version will be much lighter on the audio, but I would like

to have a small loop. Any thoughts? TIA
