I'm noticing a continuous signal apparent from the EQ notch plugin after the DSP processes audio input, i.e, either speaker test or playing MP3 file. Reloading the DSP clears this condition and signal strength is shown to be -inf on both channels. After doing a speaker test, the output is -110 dB (asymetrically +/-0.5dB). However, after playing an MP3 file, a vestige signal appears that stabilizes between -68 and -72 dB (asymetrically). This vestige signal undergoes a pronounced fluctation after terminating audio input with stabilzation occuring at that level. Many times a clear real-time fluctation can be seen occuring of a magnitude of about 0.2 dB on one or the other channel, i.e, either at the -110 dB or the -68 to -72 dB levels. I've also noticed that if I implement the oscilloscope on either channel, that channel will 'deplete' its vestige signal to -110 dB (while the non-oscilloscope channel will stabilize between -68 and -72 dB). No matter what signal strength is apparent in the peak meter when no audio program is being put through the DSP, no waveform is apparent on the oscilloscope. Moreover, this isn't anything relevent to the peak meter itself - akin to the affect of the oscilloscope - in that the condition will be evident after an audio signal is played through the DSP w/out the peak meter present at the time and the peak meter is wired up after that. I'm using v3545b on a Win2003 system w/ CT4780 sound-card. Any explanation for that?
