Don't hear any sound?
Check that your speakers are turned on and plugged into the proper connector on your computer (generally the green jack, sometimes labled Line Out). If your speakers are plugged into an amplifier, check that they are connected proeprly. Also make sure your speakers are not muted and the volume is at a comfortable listening level (both on the speakers and from your computer/device). Your volume should look like this . If you see this then your speakers are muted.

Don't see any volume controls?
If you do not see a volume setting on your computer, make sure your sound card is enabled and it is set to display the volume adjustments. You will need to go to the Sound properties of the settings of your computer. On some computers you can adjust the sound by pressing volume keys on the keyboard. There is generally a mute key which if enabled will turn off all the sounds on the computer. Look for these on the top row of your keyboard.

Speakers not balanced?
Your speakers are balanced when you hear the 3rd tone played on both speakers. It should appear to come from a center point in-between the speakers. If your speakers do not sound balanced, adjust their position and check the balance/volume level of the speakers individually on the amplifier or computer/device.

Speakers sound distorted?
First check the equalizer on the device (if it has it), it might be set inproperly. If your speakers have a pair of wires or audio signal cables set to them, check that you matched the colors up properly or your speakers will be 'out of phase'. If they still sound distorted check that your cable or speakers are not physically damanged.

Hearing the same tone out of all the speakers each time it is played?
You might have a mono cable instead of a stereo cable connected to your speakers. Stereo will have 2 channels of sound, left and right. Mono will sound the same on both.

Only one speaker is working?
Check your cabling or balance controls to make sure that both speakers is active and at proper volume. Or you might have a mono cable and your amplifier is only displaying one channel of sound.

Foreword
This page gives you access to high definition audio test files, with sample rates as high as 192 kHz. Unlike our other sections, these sounds won't play online: higher sample rates are not your browser's best friends, and cannot be encoded in the mp3 format either. Instead, these high definition files will download straight to your disk as uncompressed .wav files.
The purpose of these test tones is to offer you a way to assess the quality of your digital audio interface or digital-to-analogue converters, when fed with high-definition sample rates. These rates are able to reproduce frequencies beyond the human hearing range but can generate aliasing in the audible range too.
Use the frequency sweep files to determine if what you hear strictly relates to the input file's content, or comes from deficiencies in your high-end digital audio system as well.
These files do play frequencies that are above the human hearing range. Don't try to hear a frequency that you will never hear anyway. NEVER TURN THE LEVEL UP beyond a reasonable level. USED IMPROPERLY, THESE FILES WILL DAMAGE YOUR HEARING OR YOUR EQUIPMENT. If you are unsure how to use these files, please do not download them.
High Definition Frequency Sweeps
These sweeps start from 1 Hz up to the Nyquist frequency (half the sample rate) in a 30-second time span (linear time sweep), playing at -3dBFS.
The test starts by playing frequencies that are in your hearing range, and then they will steadily increase. As the sweep enters ultrasonic range, the sound will fade away. Listen carefully; the rest of the file should remain perfectly silent.
If you hear anything while the file sweeps the ultra-sonic range, either you have bat-ears, or - more likely - your digital audio system suffers from severe aliasing.

High Definition Chirp Tones
Chirp tones are similar to sine sweeps, but span the whole frequency range in a much shorter time: here 0.5 seconds. Each chirp tone plays at -3 dBFS. Use these files to measure frequency responses, or capture room reverberations through the impulse response method.

High Definition White Noise
White noise is characterized by a flat power spectral density: the signal contains equal power within a fixed bandwidth at any centre frequency. All files are 30-second long, and play at -3 dBFS.

High Definition Pink Noise
Pink noise is characterized by a power spectral density that is inversely proportional to the frequency: each octave carries an equal amount of noise power. All files are 30-second long, and play at -3 dBFS.
