Info

• Zoomer – Allows you to zoom in or out on the source video stream, with the additional capability of dimming the image as it passes through the filter. This can be especially useful with the Luminance Keyer (more on that actor later) to create beautiful feedback effects. The most important thing that you can do is to experiment wildly. Our experience with any software is that the most interesting things occur when you attempt to misuse it. We encourage you to do the same with Isadora. Tutorial 6: Sound Isadora allows you to play and manipulate digital audio files, though in a somewhat more limited fashion than video. Currently there are two ways to play sound: from a QuickTime movie or from a digital audio file (AIFF, WAVE, or Sound Designer II formats.) Let’s start by importing some media • Create a new Isadora document. Choose File > Import Media. From the “Isadora Tutorials” folder import the files called “voice1.aif”, “chords.aif” and “thunder.mov”. Note that the first two are digital audio files in the AIFF format, while the second is a QuickTime movie that has audio only– no video. (You can identify a “sound-only” QuickTime movie in the Media Window because a speaker icon will replace what would normally be a thumbnail image.) First we’ll work with the QuickTime movie audio. • Click “Video Sources” in the Toolbox Filter. Drag the Movie Player actor into the Scene Editor. • Set the movie input property to 1 so that the Movie Player will play the “thunder.mov” you imported above. You should immediately hear the sound begin to play. Note that you don’t have to connect the Video Player to any other modules to hear the sound play. Unlike video, sound within a movie is sent directly to your computer’s sound output and doesn’t need a Projector actor for you to hear it. • Click “Mouse & Keyboard” in the Toolbox Filter and drag the Mouse Watcher actor from the Toolbox into the Scene Editor. Connect the horz pos. and vert pos. to the pan and volume inputs of the Movie Player actor. After doing so, move the mouse around on the screen. When the mouse is towards the top, the sound is soft, towards the bottom it is louder. Moving the mouse left and right will pan the sound to the left and right audio outputs on your computer. (You will only be able to hear the sound panning left and right if you have stereo speakers built-in or otherwise attached to your computer’s audio output. Try some headphones if you’d really like to hear the effect.) • You can also change the play start and play length parameters to play a portion of the sound. Set the play start to 10 and the play length to 5. You will Isadora Manual 42
hear a short loop of the sound. In fact, all of the movie player properties will work in the same way as when playing a video QuickTime movie. • Turn off the Movie Player for now by setting is visible property to off. Now, let’s try the playing the AIFF file. • Click “Audio” in the Toolbox Filter to display the actors in the Audio Group. Drag the Sound Player actor into the Scene Editor and set its sound input property to play the “voice1.aif” file – the number will be 1 or 2, depending on which number was given to the file when you imported it. Take a look in the Media Window to be sure. • The sound does not immediately start playing like the Movie Player. That’s because you need to trigger its restart input for it to begin playing. Do that now by clicking in the restart input’s value box with the mouse. (Note that this is a trigger input, indicated by the dash. You can’t edit the value, but you can send a trigger when you click in the value edit box.) You should hear the sound of a solo voice singing a short phrase. Like the Movie Player actor, the Sound Player has a progress bar along the bottom that shows you how much of the sound is playing, and a yellow indicator line showing the part of the sound playing now. • We can make a simple sampler by adding a watcher to look for keys to be pressed on the computer keyboard. Click “Mouse & Keyboard” the Toolbox Filter. Drag the Keyboard Watcher actor into the Scene Editor. This actor allows you to trigger other actors when a key on the computer keyboard is pressed. • Click on the key range input value and type single-quote, the letter a, and then another single quote, and press enter. The key range value box should read ‘a’. This causes the Key Watcher to look only for the key ‘a’. (Note that it will not see ‘A’, or a capital a – just a small letter a.) Each time you press ‘a’ on your computer keyboard, the Keyboard Watcher sends the letter ‘a’ out of the key output. Connecting the key output to the restart input of the Sound Player so that you can trigger the sound each time you press ‘a’. • So now, press the letter “a” on your computer keyboard. Make sure your Caps Lock key is off so you’re not typing a capital “A”. When you type the letter, you should hear the sound begin to play. If you press the letter “a” again, the sound will start playing from the beginning. If you don’t press ‘a’ again, the sound will play to the end and stop. • Note that the sound stops playing when it gets to the end. This is because the loop enable property is turned off. If you change the loop enable property to “on” and press the letter “a” again, the sound will play continuously. So, what’s the difference between the Sound Player and Movie Player? The most important distinction is that Movie Player plays its sounds from your hard drive, while Sound Player loads all of the sound data into your computer’s RAM (Random Access Memory – much faster than your disk) when you tell it to play. This means that Sound Player can make seamless loops, start up instantly, and in general be more responsive than Movie Player when manipulating the play start and play Isadora Manual 43
