Q
Sound is recorded abnormally
when I select the Remove sound
echo option, connect an external
microphone, select the Play Device
> Speaker > Level tab and then
deselect Mute for the Microphone.
A This occurs because the algorithm
used to remove the echo sound
regards some of the sound as an
echo and removes this, as the
recording is done by playing the
sound from the external microphone.
► For Windows 7
After selecting the Remove sound
echo option, please select the Play
Device > Speaker > Level
tab and
select Mute for the Microphone for a
normal recording.
► For Windows XP
In this case, select Mute in the
Microphone Volume of the Playback
Mixer after selecting Acoustic Echo
Cancellation
item.
