Sound in Flash

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)

Before to start this tutorial you need a sound file, I found a website with free beats ( here you can download the beat from my example) and a icon to create a button.

1. Open Flash CS3 and create a new Flash File (ActionScript 3.0)

2. Import to Library your sound file and your icon ( File -> Import -> Import to Library )

2. Put the icon on the stage nad convert it into a Button

3. Double click on the button to enter inside of it

4. Now create a new layer for the sound file

5. Select Layer 1 and on Down layer insert a frame and a keyframe for the Hit Layer

6. It's time to put the sound file on the stage. Select the Sound layer and on Down
layer insert a keyframe and a frame for the Hit Layer

Click on the Down layer, go to Library and put the sound in the stage

7. Test your Movie (Go to Control and select Test Movie)

8. Now Save your result ( Go to File and select Publish ) and that's it!

Thank you and you can see the final result here!
