Other useful features for use of the HD Audio
Recorder app
GAIN
You can adjust the sensitivity of the sound recorded by the microphone.
The higher the GAIN value is set, the more sensitively the sound is
recorded.
LCF
You can filter any low-pitched noises such as the low hum of the air
conditioner.
The higher the LCF (Low Cut Filter) value is set, the better high-frequency
noises are filtered.
LMT
It can prevent clipping of the recorded sound. The higher the LMT (Limiter)
value is set, the more low frequency sounds that will not get clipped.
• To change additional settings, tap
type, bit depth, sampling rate and other settings.
• You can monitor sound quality with the connected earpiece while
recording audio. While recording audio in Studio mode, sound
monitoring is not supported. You can hear only the background music.
