The DM-520 features EUPHONY MOBILE – a psychoacoustic surround sound system that 
combines bandwidth correction, expansion technology and virtual acoustical source 
processing technology to allow the listener to alter the audio dynamics when playing back 
recordings through earphones. EUPHONY creates a natural, expansive feel so listeners are 
less prone to experience a closed-in feeling or to grow tired over extended listening sessions, 
such as when playing audio books. The options are: 

OFF, Natural, Wide and Power. 

EUPHONY is only applied during playback and cannot be used when recording. 

Variable Control Voice Actuator (VCVA) is a function that configures the recorder to 
record automatically only when sound is detected at a pre-set level, and stop when the 
sound drops below the threshold level. The purpose of the function is to eliminate “dead 
air” during recordings, thereby conserving memory and shortening file times. 
VCVA is enabled in the recorder’s menu.  In the DM-520, the VCVA can be set to any of 
15 different values.  The higher the value, the more sensitive the recorder is to sounds. 
At the highest level, even the faintest sound will activate recording. 

The recorder has a 

Low Cut Filter function to minimize low-frequency sounds and 

record voices more clearly. This function can reduce noise from air conditioners, 
projectors and other types of “white noise.” 

The 

Voice Filter cuts low- and high-frequency tones to create a playback frequency 

range encompassing the tones in the human voice, thereby making the playback of 
dictation recordings clearer. Voice Filter works in all playback speeds. 

Purchasing the upgrades adds the following features to the version of Olympus Sonority 
that is bundled with the DM-520: 
Plus Edition 

•  MP3 Editing – Adds the ability to output and convert to an MP3 file. With the 

MP3 format, output and conversion at 320 kbps, 256 kbps, 192 kbps and 128 
kbps as well as ID3 tag editing are possible.

•  Create a Music CD – Allows an audio CD to be easily created by specifying in the 

browsing screen the files to write to a CD. If the total size of the specified audio 
files exceeds the capacity of a CD, the files can be divided onto multiple CDs. 

•  Configuring the Recorder Menu – The built-in device settings (advanced 

settings such as the recording mode, alarm setting and timer recording) can be 
configured using Olympus Sonority.

•  Effects – Adds more than 20 types of advanced effect functions. 
•  Spectrum Analyzer – Displays the frequency distribution of the sound being 

played, in real time, on the Waveform Editing screen. 

•  Unlimited Track Editing – Eliminates the limitation on the number of tracks 

that can be edited simultaneously.

To add the Music Editing Plug-in, Olympus Sonority must first be upgraded to the Plus Edition.
