Edit and Playback Functions
Overview: The Olympus LS-12 is a compact, easy-to-use,
hand-held portable digital voice and music recorder. You can make high quality recordings
using the LPCM format, or a large number of recordings in MP3. The
recorder has a built-in 2 GB flash memory and a slot for an SD/SDHC card for
hours of recording time. It has a built-in, stereo microphone, a large 28mm diameter mono speaker, and
jacks for an external microphone and headphones. The LS-12 operates on two
"AA" Alkaline batteries. It can also work with rechargeable NiMH batteries.
LCD Display: The LS-12 features a 1-3/4" (diagonal),
LCD display which indicates recording and playback information. The recorder
will display the elapsed or remaining recording time in hours, minutes, and
seconds. When not recording, the current time can be displayed. You can set the
display contrast to one of 12 levels, and the backlight duration to 5 sec, 10
sec, 30 sec, or 1 minute.
Date and Time: The recorder features a built-in clock. If
you have set the time and date, information as to when a sound file was recorded
is stored automatically with that file.
Built-in Microphones: The unit features two built-in,
high-quality microphones on the top of the recorder. Each microphone can produce
high quality recordings of sounds up to 130dB SPL without clipping. You can set the recording level to High,
Middle, or Low. The microphone limiter can optimize the recording for music or
voice. In addition to the built-in microphones, the
recorder also has a 3.5mm external microphone input.
Line Input: You can make recordings directly from another
device without using the microphone. The 3.5mm Line In jack has a higher
impedance than the Microphone Input jack for a cleaner recording without system
Built-In 2 GB Flash Memory: The LS-12 Digital Voice
Recorder features a built-in 2 GB flash memory which can hold hours of audio or
voice memos. The memory is divided into three folders for organizing recordings,
and separate folders for MP3 or WMA music transferred from Windows Media Player
or iTunes. A portion of the built-in memory is used for management files,
therefore the total recording capacity is approximately 1.4 GB.
Memory Card Slot: In addition to the 2 GB built-in memory,
the LS-12 has a memory card expansion slot for more recording capacity. The slot
will accept SD and SDHC memory cards from 2 GB to 32 GB. Files can be
transferred from the card to the internal memory or vice-versa.
USB: The LS-12 has a Mini-B 2.0 USB port on the side for
connecting the recorder to your computer for transferring files. A short USB
cable is provided with the unit. The LS-12 is compatible with the following
Operating Systems: Windows XP (SP2, SP3), Windows Vista (SP1), Windows 7,
Windows 8, and Mac OS X 10.4.11 - 10.8.
Headphone Jack: The LS-12 has a 3.5mm jack for plugging in a
pair of headphones. You can listen to files played back or monitor the recording
as it is made.
Power Requirements: The recorder is powered by two
"AA"-sized alkaline batteries (included). Fresh batteries will provide
approximately 50 hours of recording time. You can
also use NiMH batteries, if desired. The Power Saver mode turns off the monitor
and switches the unit to standby if it is not used within a preset period of
time (5 min, 10 min, 30 min, or 1 hour).
Remote Compatible: You can control the LS-12 with an
optional RS-30W remote control. The remote is wireless, with a module that plugs
into the recorder's 2.5mm sub-mini remote jack.
Tripod Socket: The LS-12 is equipped with a standard 1/4"
tripod socket on the back so you can mount the recorder onto a tripod, if
Recording Format: The LS-12 records audio files in LPCM and MP3 formats in
nine recording quality modes. Files are limited to approximately 2 GB for LPCM
and approximately 4 GB for MP3. If a Linear PCM recording goes longer that 2 GB,
the 2 GB file is closed and the recorder automatically creates a new file to

Recording Modes: The front panel-mounted Mode Dial lets you
set the recorder to one of three recording modes or to the built-in instrument
tuner and metronome:
- Smart Mode: The Smart Recording Mode lets you set the
recording level automatically during a "Smart Time" period of 10 seconds, 30
seconds, 1 minute, or "endless" During the Smart Time, the recorder sets the
maximum recording level based on the volume input.
- Manual Mode: In the Manual Recording Mode, the
recording level is set manually prior to recording. The display will show
"OVER" if the level is set too high for the audio source. While recording
with the microphone, the level can be adjusted between 01 and 70. If using
the Line In jack, the level can be set between 01 and 30.
- Quick Mode: The Quick Recording Mode lets you record
immediately by pressing the Record button.
- Chromatic Tuner: The recorder features a built-in chromatic tuner for
tuning an instrument, and a metronome with an adjustable tempo. There are
two tuner displays: a meter and a graph.
Pre-Recording: Pre-recording enables you to start recording
up to 2 seconds before you press the Record button. This enables you to avoid
missing the exact moment a recordable event begins.
Low Cut Filter: The LS-12 has a Low Cut Filter to minimize
low frequency sounds and selectable cut-off frequencies of 100Hz and 300Hz. This helps make voice recording clearer, especially in
Overdubbing: The Overdubbing function enables you to dub
sound over a pre-recorded file while listening to it. The selected file to be
overdubbed and the Recording Mode must both be set to LPCM 44.1kHz/16-bit.
Edit and Playback Functions
Playback Speed: You can adjust the playback speed as you
desire; slowing it down to review spots you couldn't understand, or speeding it
up to listen to meeting content at a faster speed. Digital processing keeps the
pitch at normal levels while you increase or decrease the playback speed. During
playback, you can adjust the playback speed between -0.5x and +3.0x in 0.1x
Skip Space: The Skip Space function lets you skip forward or
backward during playback. This is handy for quickly skipping to another playback
position or repeatedly playing back short phrases. You can choose Forward Skip
(file, 10 sec, 30 sec, 1 min, 5 min, or 10 min) or Reverse Skip (file, 1 sec, 5
sec, 10 sec, 30 sec, 1 min, 5 min, or 10 min).
Index Marks: Setting an index mark lets you quickly find a location you want to listen to while fast forwarding or
fast rewinding. For files not recorded on an Olympus digital voice recorder,
Temp Files can be inserted into recordings. Up to 99 index or file marks can be placed on a single file.
Segment Repeat: The Segment Repeat function, also known as
A-B Repeat, enables you to repeat playback of part of a particular file. You can place marks at the beginning and the
ending of a recorded passage for repeated playback. This constant repetition
feature can be used for language learning.
Editing: Recorded tracks can be edited in the recorder using
the File Divide and Partial Erase operations.
Erase: You can erase your recorded
messages one by one, or all messages in a folder at one time.
Protect Files: To prevent a file from being accidentally
erased or edited, you can protect an important file. When a file is protected,
it is regarded as a read-only file. Protection can be released, if desired.
Hold Function: The LS-12 has a Hold function that will lock
the buttons to prevent accidental operations. The Hold function is activated by
sliding the power switch to the left.
