Á High-pass filter
Cuts off unneeded low-band audio. The cutoff frequency is 80
Hz.
Á Echo canceller (p. 50)
Suppresses the voice echo that can occur when using a web
conferencing system that includes a speaker and mic.
Á Anti-feedback (p. 50)
Suppresses audio feedback.
Á Noise gate
Eliminates audio that is lower than the specified threshold
level. This is effective when the noise that you want to remove
is separate from the audio that you want to keep, and can be
used to remove hiss or other noise that is heard during periods
of silence.
Á De-esser
Reduces sibilant noise (the sounds you hear when pronouncing
“s” words and other hissing sounds).
Á Compressor
Audio that exceeds the specified threshold level is compressed.
This reduces the difference between the maximum volume
and minimum volume, making the audio more comfortable for
listening.
Á Equalizer
This is a four-band equalizer. It lets you adjust the volume by
boosting or cutting four frequency regions.
Á Voice changer (p. 50)
Transforms the pitch or character of the voice.
Á Delay (p. 50)
Outputs audio with a delay.
Á Reverb (p. 51)
Adds reverberation to the sound.
