Note:
If you experience low-frequency artifacts on a voice when using subharmonic synthesis, try engaging a high
pass filter, using EQ, or a combination thereof on the vocal’s mixer channel to reduce the artifacts. If a high pass filter
and EQ are not enough, try lowering the overall amount of Subharmoic Synthesis applied to the signal by adjusting the
SUBHARMONICS parameter.
Note:
The left and right input signals are summed to mono before the subharmonic synthesizer processes the audio.
The subharmonic synthesis effect signal is then output as a mono effect and mixed in with the unprocessed audio signal.
Any panned signals which contain enough low-frequency content to trigger the subharmonic synthesis effect will output a
mono summed effect signal, which will be played out of both the left and right PA loudspeakers.
