Choosing the best audio quality for the sound and music in your flash movie is a compromise. Large file sizes give great audio quality with slow loading times, but compressing a file too much to get it smaller and load quickly, and the audio quality can easily get worse.
It’s good to start with the best audio quality you can, which is why all the royalty free flash music loops we supply at www.royalty-free.tv are in WAV format, the same high quality as audio CDs. Once you import the WAV loop into your movie, you’ll need to compress the file to make it a smaller file size, so that it loads faster. Using Flash, click the Sound icon in the library, then on the pop-up menu that appears select Properties to open the Sound Properties dialogue box. Here you can experiment with different audio settings, generally MP3 is a good format to choose, and the lower the number you choose for the bit rate the smaller the file size will be – but the audio quality will also be lower. A good compromise is generally 128 bit, which gives audio quality not too far from CD quality, but with a file size of almost 90% smaller than a WAV, which means the loading speed shouldn’t be a problem.
