Module 4- Build a Game I Can’t Hear You! Sound
Sound formats in Scratch Scratch can read MP3 files and uncompressed WAV, AIF, and AU files. Just like images, sounds can also be compressed to make them smaller in size. MP3 files are an example of this.
So what’s it all about?... Uncompressed sound files: AIF files Gold standard of audio files, Highest-of-high-quality uncompressed audio that you can save on a disc. AIF files sound great, but files are huge. WAV file, or waveform audio file Known as simply.wav after its extension. A common type of sound file. Can also be quite large. AU file An audio file typically created on a Sun Microsystems or Unix-based machine. Not that common and quite large.
Compressed sounds - MP3… MP3 files contain music and other audio. They are popular because they compress music down to a very small size while maintaining quality. Files are small, making MP3s ideal for iPods and for the internet.
And now over to you… Go to the website http://www.pacdv.com/soundshttp://www.pacdv.com/sounds. All sounds are in mp3 or wav formats suitable for use in Scratch. Choose a sound effect you would like to add to your project in Scratch.
