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  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.
