ALL THE FOLLOWING TEST SIGNALS ARE MP3 AND
SHOW A DURATION OF 10 SEC
These signals
are intended for testing of equipment, you could either copy
them to an MP3 player or burn them to a
CD. The
mp3-signals have to be converted to <wav> format first,
before
you can burn them to a CD. Since 10 seconds are short, you had to set
your player to A -> B repeat or multiply the signals before
burning.
0Hz_dig-silence
is
a signal, containing anything at all. It is "digital silence". You may
use
it to determine DC-operating points as well as for determining noise
figures from your equipment.
440Hz_-6dB_inphase
contains a 32bit/192kHz, purely digitally generated sine-wave of 440Hz
and a level of -6dB. Both channels are in phase. Afterwards is was
down sampled and converted to mp3-format.
440Hz_-6dB_90deg-phase
contains the same as the former signal, but both channels show a
constant phase margin of 90 degrees electrically. It may be used for
phase tests.
440Hz_-6dB_180deg-phase
is again the same, but out of phase (180 degrees electrically).
440Hz_fullscale_20k2
is a signal for testing equipment in the view of harmonics
content
or treatment. It was generated the same way and contains a full-scale
440Hz sine-wave with a defined additional portion of 20% of k2 (880Hz).
440Hz_fullscale_20k2-5k3
is the same as above, but containing additionally 5% of k3 (1,32kHz).
440Hz_fullscale_20k3
is again the same as above, but containing only an additional portion
of 20% k3 (1,32kHz).
