Troubleshooting

No Sound Input

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. I used to recommend a pre-amp called iMic from Griffin Technology, but they have discontinued the product. However, there appear to be many of them still available on eBay.

Do not use a USB Microphone with Intonia on the Mac. There is a long-standing bug with the OSX implementation of Java that Apple refuses to fix.

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.

Low Volume for Sound Input

The slider under the microphone icon on the volume controls controls the input level. It should be as high as it will go without causing the VU meter next to it to turn red.

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:

  1. Choose Apple Menu > System Preferences and click Sound.
  2. Click Input.
  3. Select the input device whose volume you want to control.
  4. The input level meter shows you how loud or soft the sound from the selected input device is registering.
  5. Drag the Input Volume slider left or right to lower or raise the input volume.

Very Slow Response

Some OSX users, particularly on OSX Yosemite, have reported very slow response. This is usually due to a competing process on the computer that hogs the CPU. To see what processes are running on an OSX computer, use the Activity Monitor, which resides in /Applications/Utilities, or type command-space and type "activity". If there's a process that shows a high %CPU, killing that process should get Intonia working properly.

No Output Sound or Incorrect Volume for Output

Make sure your speakers are turned on and that they're properly connected to your computer. Make sure the volume slider is at a reasonable level, and that Mute is not checked.

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:

  1. Choose Apple Menu > System Preferences and click Sound.
  2. Click Output.
  3. Make sure "Show volume in menu bar" is checked.

Poor Results analyzing sound from YouTube or other Digital Sources

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.

Intonia Will Not Start Up

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.

Clicking "Record" Does Not Start Recording

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.

"Not a Supported Audio File Type" Error

If you get an error message "File xxx.wav is not a supported audio file type", it may be because the .wav file uses the Microsoft ADPCM encoding instead of the usual PCM encoding. Some inexpensive voice recorders create .wav files with this format. However, the Java Sound package that Intonia depends upon does not support Microsoft ADPCM.

If you have a file that is in this format, you can convert it to PCM encoding by using Audacity to read the file, then "Save As" to create a copy.

Issues with 64-bit Java: Windows

A serious bug has been uncovered in the 64-bit implementation of Java for Windows 7. This bug appears to have been fixed in update 30 of Java 6, which was released in October of 2011. Intonia will refuse to run when it detects a Windows 64-bit Java environment older than Update 30. If this happens, download a new version of Java and re-install it. You can always find the latest version of Java at http://java.com.

Issues with 64-bit Java: OSX

A problem has been reported running Intonia under the 64-bit implementation of Java under OSX. It happens sporadically on some computers and not others. The symptom is that Intonia will refuse to start up, and a message wil be displayed saying, "com.intonia.tony.Intonia quit unexpectedly."

The first thing to try is to load the latest version of Java from href=http://java.com. When the download completes, double click the .dmg file to install it.

If reinstalling Java doesn't work, switching to the 32-bit implementation of Java has sometimes been found to fix the problem. To do this:

  1. Click on Finder
  2. On the left pane, select Applications. Scroll down to Utilities.
  3. Open Java Preferences
  4. On the lower half of the General tab, make sure a 32-bit version is enabled, and drag it to the top of the list.
