There are a few important things to know about
using, listening and navigating through this site, no matter what browser
2. Text that is in red indicates that the word is being introduced or defined for the first time. When you click on the index button, you'll find that word listed there, along with other page numbers related to that topic. There is one exception to this:
If the red text indicates a figure number, you're taken to that location. In most cases the particular figure is on the next page or two. To go back to where the figure was mentioned for the first time, click on the word return located within the figure.
3. Any text that's in black is a sound example. Clicking on 'click here' will play a sound out of your loudspeakers or headphones. Going to the next sound example, or clicking the next or previous button will mute the sound.
4. Numbering of figures and chapters. The number before a decimal point refers to one of the eleven chapters in this site; the number after the decimal point is the figure or page number. For instance, page 4.6 refers to Chapter 4, page 6; figure 9.3 refers to Chapter 9, Figure 3.
5. The volume control slider. There's a volume control throughout most of this site that appears at the left side of the text. Click the mouse on the red slider, and while holding the mouse down, move it back and forth. This adjusts the relative volume level; note that other volume controls on your sound card software may affect the final volume level that is heard.
Some Important Notes About
Some of the test tones and sine waves can actually damage your hearing or your sound system if you listen to them too loud. For those sounds, you'll see the following warning sign on the page:
Start in these examples with the volume slider down, and especially don't put headphones on until you've tested the sound example on a page with this warning. Then work the slider up higher progressively. If you've hooked into an external amplifier or powered speakers, start with low volumes on those systems as well.
Unlike a lot of multimedia packages, which set out to dazzle you with an unfamiliar interface and lots of fancy graphics, this site is best thought of as a talking book with both figures and sound examples. You're encouraged to listen at least several times to the examples, sometimes at different sound levels, sometimes through loudspeakers, and sometimes through headphones. When reference is made to a previous section of this site, you're encouraged to compare previous sounds as well as previous parts of the text. Nothing compares to careful, repeated listening of sound examples to learn about a new audio concept. In some cases, the audio examples are very obvious, and in other cases the examples are subtle. While a low-grade audio system will mask some of the effects, a wide variety of standard consumer multimedia computer configurations should work just fine for hearing all of the examples.
On a few of the examples, especially Chapter 9, it's best if you use a pair of good quality headphones. Your computer may have a headphone jack with a volume control.
