Today we learn how to create play on click button in Flash CS3! Here is the final result!
To add some great sound to your Flash movie, you must first import the sound. You can import AIFF, WAV, and MP3 sounds. Flash places these sounds in your Library.
Sounds vary in sample rate, bit rate, and channels. These statistics are important because they affect the quality and size of the sound file. Of course, the length of the sound also affects its size. Here’s what you need to know:
- Sample rate: The number of times the recorder samples an audio signal when it’s recorded in digital form. Measured in kilohertz (kHz). Try not to use more than 22 kHz unless you want CD-quality music.
- Bit rate: The number of bits used for each audio sample. Sometimes called bit resolution. A 16-bit sound file is clearer with less background noise, but use 8-bit sound if you need to reduce file size.
- Channels: Typically one channel of sound (monophonic) or two channels (stereophonic). In most cases, mono is fine for Flash files and uses half the amount of data that stereo uses.
Often, you need to take a sound as you find it unless you have software that can manipulate sounds. Luckily, you can set the specs of sounds when you publish your movie to an .swf file. You generally get the best results by
starting with high-quality sounds and compressing during publishing ( Information from Flash CS3 for Dummies ebook)
