SHORT DESCRIPTION OF TEST WAVE FILES


0_16.wav: Extreme pure sine (0.001% THD+N) with maximum level. Peak level meters must show exactly 0 dBFS, the corresponding RMS-value is exactly -3 dBFS.

50_16.wav: Sine with a level of -50, -60, -70, -80 and -90 dBFS, allows an easy test of the effective dynamic. Many soundcards claiming the use of 16 bit technology will not let you hear -90 dBFS sine but only noise.

dc_16.wav: DC (0 Hz) at -20 dBFS. This file allows testing whether a digital device uses, transmits or changes dc levels. Also wether digital level meters show dc levels or not.

20khz_16.wav: 20 kHz sine with -10 dBFS. This signal is inaudible for 99.9% of all human beings. Normally only a short click should be heard at the beginning and the end. Depending on the quality of the used DAC noise, low level whistles or other tones may occur.

crest_16.wav: Multisine with very high crest out of 40 single sines between 40 Hz and 20 kHz, its peak level is exactly 0 dBFS. Very good for checking the accuracy and precision of level displays, because the RMS-value of this signal is only -16.1 dBFS.

100_24.wav, 110_24.wav, 120_24.wav:
1 kHz sine with -100 dBFS, -110 dBFS and -120 dBFS. These very low levels can of course only be processed in 20 or 24 bit technology. In most cases you will not hear -120 nor -110 dBFS, because the sine is hidden behind the noise of the DAC.

0_16_96.wav: Extreme pure sine (0.001% THD+N) with maximum level. Peak level meters must show exactly 0 dBFS, the corresponding RMS-value is exactly -3 dBFS. Sample rate 96 kHz!

crest_96.wav:Multisine with very high crest out of 40 single sines between 40 Hz and 40 kHz, its peak level is exactly 0 dBFS. Very good for checking the accuracy and precision of level displays, because the RMS-value of this signal is only -16.1 dBFS. Sample rate 96 kHz!

8.wav: Demonstrates that Windows own sound system is capable of more than two channels. There has to be a 8-channel device in the system, and has to be set up as preferred playback device in multimedia. Then play back this file using the Media Player. Note: Does not work with the Media Player of Windows 98 update!
