Recording sounds of nature
Scene 2
The following settings are recommended for outdoor recording of sounds of nature such
as bird songs, the murmuring of a stream, or even the sound of a steam locomotive.
|
Rec Mode setup
When recording bird songs or the sound of a steam locomotive, the linear
PCM (WAV) mode is recommended, as it has the capability to capture
close-to-original sounds. However, since linear PCM (WAV) format files take up
a lot of recording space, it is recommended to use an SD/SDHC card or record
audio in the MP3 or WMA format when extended recording is required.
|
LS-10 recording position
The quality of the recorded sound can vary greatly depending on where the LS-10 and/or the microphones are
positioned. When recording the sound of a moving steam locomotive, position the built-in stereo microphones of the
LS-10 parallel to the rails. The recorded audio will move from the right to the left (or vice versa), providing a dynamic stereo
feeling. When the recorder is installed horizontally at ear level, sound close to what you actually hear can be recorded.

Recording function setup
Set the MIC SENSE switch to HIGH when recording a low-level sound such as birds' songs or murmuring of a stream or
to LOW when recording a louder sound such as a steam locomotive. The recommended Rec Level setting is MANUAL.
Tips
Using windscreen for reducing wind noise
Wind noise in outdoor recording is grating, but the high-sensitivity microphones of the LS-10 also capture soft rustling breezes that
are usually not sensed by human ears. This kind of wind noise can be attenuated by attaching the provided windscreen to the LS-10.
Using external microphones to accurately capture the target source
If the built-in microphones cannot be placed close enough to the recording target, it is recommended to use external
microphones. External microphones with high directivity will be able to capture the target sound clearly even when it is as
low as a bird's song. The monopod allows the microphone to approach the target and is therefore useful outdoors.

Recording function setup
Available recording time of
internal memory (2 GB) (Reference values)
The Zoom Mic function makes it possible to capture
the sound by selecting the direction and area to be
emphasized in recording. To record the speaker's
voice clearly in an interview, set the MIC SENSE switch
to LOW and approach the microphones to the
speaker's mouth. The recommended Rec Level setting
is AUTO because this frees you from worrying about
recording level adjustment.
Using external microphones
Even in a wide conference room, speakers in distant positions can be captured using an optional ME30W 2-channel
microphone kit as the external microphones.
Benefit of low-cut function in a conference room
The built-in microphones of the LS-10 have such high sensitivity that they tend to capture unnecessary sounds that are
usually ignored by the human ear. If this causes a problem, set the LOW CUT switch to ON. This position will effectively cut
the continuous low-frequency sounds from air conditioners, LCD projectors, etc.
