Check if all your speakers are functioning properly by checking them individually. In the main speaker test section you will two wave icons left and right so you can test each speaker individually and note if they're properly connected, or if your balance is properly panned.
Lower frequency files are ideal to use as a subwoofer test. In the last page of the library, you'll find sounds that go in crescendo or decrescendo. Use these files to measure the range of your audio equipment and your own ears, also ;-. We all know what that is and how it can affect us. Deeming something as noise is highly subjective on the listener's end. What many people probably don't know is that noise, despite being sound waves, can also have different colors.
We can relate sound waves to light. In the same way that white light is formed by the superposition of every color and black is the absence of light and color, we can speak about the color of noise depending on the sound frequencies that form it. So, even if we can't actually see it, noise will have one or other color depending on each of the noise's frequency's contribution. Mind that most consumer audio equipment, like PC speakers, won't be able to reproduce anything below 50Hz or above 16kHz, or worse.
If you want to test your ears, you should use high-quality headphones, and a high-quality sound card. It is possible that low-quality equipment will produce audible distortion on the highest frequencies, giving you the false impression that you can hear them after all. The sweeps come in 2 varieties: linear and exponential. The exponential sweep is the most "natural" sounding one, because the frequency response of our ears is logarithmic.
In this sweep, there is always the same amount of time between the doubling of the frequency, i. The linear sweep, on the other hand, has the advantage that it's easier to determine which frequency is playing at a certain moment. This means that the instantaneous power of the sound wave is constant, and the total power in each octave is the same.
The reason why this keeps the power of the sound wave constant is that the power of a sound wave is proportional to its frequency squared. Chirp tones are similar to sine sweeps, but span the whole frequency range in a much shorter time: here 0. Each chirp tone plays at -3 dBFS. Use these files to measure frequency responses, or capture room reverberations through the impulse response method. 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 second long, and play at -3 dBFS. 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. Is AudioCheck free?
