Be sure your computer has a microphone. Many computers have built-in microphones; others require a separate mike to be plugged in. Your microphone should be plugged in before you start Intonia.
Most Apple computers have a built-in mike, but the Mac Mini does not. Apple computers have a Line In jack, which should not be confused with a Microphone In jack. Most microphones do not have voltage levels sufficient to interface to a Line In jack. If you plug an external microphone into an Apple computer, you'll need a separate pre-amp such as iMic.
Near the upper right corner of the screen are the volume controls, that look
like this:
If the microphone icon is missing, it may mean your computer does not have a sound card, or the sound card does not support microphone input. On some Windows Vista computers, the microphone icon will will not appear if the microphone is plugged into the input jack after Intonia is started. If your computer does not allow microphone input, you can still analyze pre-recorded .WAV files with Intonia, but you will not be able to record new sounds.
Be sure you've selected the microphone as the sound source. On Windows XP, the Input Source option on the Audio tab of the Options menu may allow several different sound sources; make sure the option corresponding to your microphone is checked.
On Windows Vista, you'll need to open the Control Panel and select Sound. Choose the Recording tab, and make sure the correct microphone input is selected. Then click "Properties", and select the Levels tab. The microphone volume should be as high as it will go.
On Windows Vista, there is a separate master input volume control that cannot be manipulated by Intonia. To access it, open the Control Panel and select Sound. Choose the Recording tab, and make sure the correct microphone input is selected. Then click "Properties", and select the Levels tab. The microphone volume should be as high as it will go.
On some Windows Vista laptops, the Input Source option on the Audio tab of the Options menu may show two input sources, both labeled "Master Volume". If Intonia's volume slider does not have any effect on the input level, try selecting the other source.
On Macintosh OSX, the volume sliders do not appear. To control the input volume, use the following procedure:
If the speaker icon is missing from your volume controls, it means your computer is not capable of playing sounds. You will be able to use Intonia to visually analyze pre-recorded .WAV files, but you will not be able to play the sounds back through your speakers.
On Windows Vista, there is a separate Speaker Volume control that Intonia is not able to control. You can access it using the little speaker icon at the right end of your taskbar. Make sure the volume level is reasonable and the speaker is not muted.
On Macintosh OSX, the volume sliders do not appear. The output volume on a Mac may be controlled by using the speaker icon on the menu bar, near the upper right of the screen. If this icon does not appear, use the following procedure:
If your sound card supports "What You Hear" as an input source, you can send the audio from YouTube or the output of a software MP3 player directly into Intonia where it can be analyzed or saved as a .WAV file. If you do this, it is important that you set the Sample Rate For Recording on the Audio Tab of the Options dialog to match the sample rate of the source. YouTube audio has a sample rate of 22,050 KHz. MP3 files have various rates: use a tool such as Audacity to find out the sample rate of each file.
It may happen that Intonia will appear to install correctly, but double-clicking the Intonia icon on the desktop does nothing. On Windows computers, this may be a symptom of corrupted file type associations. (In one reported case, a Nokia cell phone sync suite turned out to be responsible.) Reinstalling Java should fix the problem. Java for Windows can be found at http://java.com.
If you click "Record" and nothing happens, check the state of the "Pause" button. The Status Display to the right of the Transport Controls will include the word "Paused" when the pause button is depressed.
By default, One-Touch Play/Record is turned on. In this mode, Intonia will automatically open a new file in "Recording, Paused" mode, and open an existing file in "Playing, Paused" mode. This makes it easy to start and stop recording or playback by simply pressing the spacebar.
