What enhancements does the PLUS upgrade to DSS Player offer?

Purchasing the DSS Player v.7 PLUS upgrade adds the following features to the version of DSS Player bundled with the DS-61:

  • Splitting files--Individual audio files can be split into smaller units. This is especially useful if a file is longer than the capacity of an audio CD used for archiving.
  • Joining files--Individual audio files can be joined together into a longer single file. This is useful when there are many short recordings on a similar topic that would be more convenient to archive or share as a single audio file. Files that are to be joined must be recorded in the same quality mode.
  • Voice Recognition--Creates compatibility with voice-to-text applications IBM ViaVoice® 10 or Dragon NaturallySpeaking® 8 and 9 Preferred.

What is Voice Recognition?

Voice Recognition is technology that enables an application to "listen" to the playback of an audio dictation file and convert its contents to a text document. DSS Player version 7 is compatible with IBM ViaVoice® Pro USB Edition 10, and Dragon NaturallySpeaking® versions 8 and 9 Preferred.

The Voice Recognition software must be trained to understand individual speakers. The applications can create accounts for individual speakers who have read prepared text under controlled conditions into the digital voice recorder to be used. Corrections to the text by the transcriptionist can be incorporated by the voice-to-text software to "learn" how the dictator speaks. If the users correct their own text files, they can also learn to enunciate words so the software can better understand the speech and increase the accuracy of the text file.

Voice Recognition performs poorly in meeting or lecture situations because of the presence of untrained voices and varying acoustics that will confuse the software.

What is EUPHONY?

The DS-61 features EUPHONY MOBILE - a psychacoustic surround sound system that combines bandwidth correction, expansion technology, and virtual acoustic source technology to allow the listener to alter the audio dynamics when playing back recordings. EUPHONY creates a natural, expansive feel so listeners are less prone to experience a closed-in feeling or growing tired over extended listening sessions, such as playing audio books. The options are: OFF, NATURAL, WIDE, and POWER.

EUPHONY is only applied during playback. It cannot be used, and its effects cannot be saved, when recording.

What is VCVA?

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 DS-61, 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.

What is the function of the LowCut filter?

The recorder has a LowCut 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."

Return to Top

What is the function of the Voice Filter?

The Voice Filter cuts low- and high-frequency tones to create a playback frequency range encompassing only the tones that can be produced by the human voice. This makes playback of dictation recordings clearer. Voice Filter works in all playback speeds.

Return to Top

What is the function of Noise Cancel?

Noise Cancel can be enabled to reduce background noise in recordings made in noisy surroundings. In effect, the function treats the loudest sounds as the most important and reduces other sounds to make the dictation clearer.

The Noise Cancel options are OFF, LOW, and HIGH. The options are set in the recorder's menu. The LOW or HIGH settings remain valid until Noise Cancel is set to OFF. Noise Cancel is not available while the Voice Filter is set, and it cannot be used during Slow or Fast playback.

What are Index Marks and Temp Marks?

Index Marksare digital tags that can be inserted while recording or during playback. They are used to skip forward and backward in recordings to pre-selected points. Up to 16 Index Marks can be added to a single file.

Index marks cannot be placed in files created on machines other than Olympus digital voice recorders. This means that they cannot be placed in podcasts. Instead Temp Marks can be placed in podcasts to temporarily remember desired locations. Up to 16 Temp Marks can be added to a single file.

Both Index Marks and Temp Marks are inserted using the [INDEX] button on the recorder. Index Marks and Temp Marks cannot be added in the Audible function.

What is the purpose of the Audible folder?

The Audible folder is present to download and play audio content from the® website ( is a source for audio books and audio newspaper and magazine articles. Audible also has web sites for the United Kingdom, France, and Germany that offer content in other languages.

Audible files are not managed by the DSS version 7 software. When users purchase a subscription to, they receive Audible Manager software. The DS-30, DS-40, DS-50, DS-61, and DS-71 are listed in the Mobile Device listing in Audible Manager. Audible Manager is used to download audio content from and transfer files to the recorder's Audible folder.

When the Audible folder is selected on the recorder, the recorder automatically switches to the Audible mode. The Audible mode is able to play the downloaded Audible files in any of the three formats used by Audible. The different modes determine the quality and file size properties of the downloaded files. Only those Audible files that have a .aa file extension are displayed in the Audible mode.

Re-Playable Audible File Formats

Mode Codec
ACELP (8.5 kbps)
ACELP (16 kbps)
MP3 (32 kbps)

When a content file is transferred to the recorder, a .pos file is created to record the playback position of a file. This allows the recording to take up where it had left off during a prior listening session.

Technical support for the Web site, software and content download process is not provided by Olympus Digital Technical Support.

How much dictation recording time is available in the DS-61?

The length of the potential recording time available in the DS-61 is governed by the recording quality mode that is selected. When a quality mode is selected, several audio file properties are put into place. These properties determine the level of detail of the saved file data. A higher-quality data file saves more-detailed information and creates a larger data file that uses more memory space. A lower-quality recording makes a less detailed data file, so the memory goes a lot farther. Podcast and Audible files use up portions of the recorder's built-in flash memory, as do files saved on the recorder used as a USB flash drive (aka "thumb"drive). This usage will reduce the amount of memory available for recording new files.

The table below shows the maximum dictation recording times possible (assuming there are no other files saved in the recorder).

Quality Mode Maximum Dictation Recording Time
STEREO XQ mode 33 hours 50 minutes
STEREO HQ mode 67 hours 40 minutes
STEREO SP mode 135 hours 30 minutes
HQ mode 135 hours 30 minutes
SP mode 266 hours 50 minutes
LP mode 530 hours 50 minutes

The different quality modes save the digital record of the recording with different levels of faithfulness to the original sound. The STEREO XQ and STEREO HQ modes are recommended for music, drama, or interviews that may be made for broadcast. These quality modes make very detailed digital records of the sound and use a very wide frequency range that may exhaust the available flash memory very rapidly. Lower-quality modes, such as SP (Standard Play) and LP (Long Play), make less-detailed records of the sound and use a narrower frequency range, so they will use up the available flash memory much more slowly. These modes are best used for situations in which large content capacity is more important than high audio quality - for example, for taking notes or recording college lectures or seminars.

What are the maximum recording times per file?

A maximum recording time per file is set in the recorder for each quality mode. Even if a recorder's memory is not exhausted, a single recording cannot be continued beyond the limit.

Quality Mode Recording Time
STEREO XQ mode 26 hours 40 minutes
STEREO HQ mode 26 hours 40 minutes
STEREO SP mode 53 hours 40 minutes
HQ mode 26 hours 40 minutes
SP mode 53 hours 40 minutes
LP mode 148 hours 40 minutes

How can the visually impaired set the time and date in the DS-61?

The recorders' built-in audio cues can be used to enter the Time & Date settings. These same cues can be used to set Timer Recording and Alarm functions as well.

Using the Keypad

When executing a menu function that requires time and date setting, use the buttons on the recorder's four-way keypad to enter the settings. The settings are hour, minute, month, day, and year. Press the PLUS (UP) and MINUS (DOWN) buttons, respectively to increase and decrease the values. Press the REWIND (LEFT) and FAST FORWARD (RIGHT) buttons to move between variables. Press the OK/MENU button to complete the set-up and start the clock.

Each time and date variable has a baseline value, from which it is possible to calculate the number of times the PLUS (UP) or MINUS (DOWN) buttons must pressed to reach a particular value. The baseline settings for hour, minutes, month, day, and year are respectively 12 AM, 00, 1M, 1D, and 2007Y. The values appear on the recorder screen as shown below:

When setting time and date variables the recorder emits distinct audio cues to determine that the variables are being changed. Pressing the PLUS (UP) button causes the recorder to emit a high-pitched beep. Pressing the MINUS (DOWN) button elicits a low-pitched beep. When a baseline value is reached from either direction, the audio cue becomes a chirp.

The DS-50 digital voice recorder has a Voice Guide that speaks the menu items. However, it cannot speak the time and date or file names. When the recorder is turned on for the first time , the Voice Guide function is enabled. If the Voice Guide is disabled, use the following steps to enable it:

  1. Turn the recorder on by sliding the POWER/HOLD button downward.
  2. Launch the menu by holding down the OK/MENU button in the center of the four-way keypad for 1 second.
  3. Press the MINUS (DOWN) button 13 times to arrive at the Voice Guide setting in the menu.
  4. Press the FAST FORWARD (RIGHT) button on the keypad twice.
  5. Press the OK/MENU button in the center of the keypad once to enable the Voice Guide.
  6. Press the REWIND (LEFT) button on the keypad once to return to the menu.

Setting the Time and Date

  1. If the Voice Guide has just been enabled and returned to the menu, press the MINUS (DOWN) button 7 times to arrive at the Time & Date setting. The Voice Guide will speak, "Time and Date Setting."
  2. If the menu has been newly opened, press the PLUS (UP) button four times to arrive at the Time & Date setting.
  3. Press the FAST FORWARD (RIGHT) button to open the Time & Date menu. The first variable to set is the hour. Press the PLUS (UP) button or MINUS (DOWN) button until the recorder chirps instead of beeps. The chirp means the hour variable has been set to 12 AM.
  4. Press the PLUS (UP) button the number of times necessary to arrive at the correct hour value. Remember: The baseline value for hour is 12 AM. Therefore the first 11 button presses represent AM values. It may be quicker to press the MINUS (DOWN) button and count backward from 12 AM if the correct time is a PM value.
  5. Press the FAST FORWARD (RIGHT) button to move to the minute variable. Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps. The chirp means the minute variable has been set to the baseline value of 00.
  6. Press the PLUS (UP) button the number of times necessary to arrive at the correct minute value. If it would be quicker to count backward to the minute value, the MINUS (DOWN) button can be used to arrive at the correct minute value.
  7. Press the FAST FORWARD (RIGHT) button to move to the month variable. Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps.The chirp means the month variable has been set to its baseline value of 1M, representing January.
  8. Press the PLUS (UP) button the number of times necessary to arrive at the correct month value. If it would be quicker to count backward to the month value, the MINUS (DOWN) button can be used to arrive at the correct month value.
  9. Press the FAST FORWARD (RIGHT) button to move to the day variable.Press the PLUS (UP) or MINUS (DOWN) button until the recorder chirps instead of beeps.The chirp means the day variable has been set to its baseline value of 1D, representing the first day of the month.
  10. Press the PLUS (UP) button the number of times necessary to arrive at the correct day value. If it would be quicker to count backward to the day value, the MINUS (DOWN) button can be used to arrive at the correct day value.
  11. Press the FAST FORWARD (RIGHT) button to move to the year variable. The year value is selected by using the PLUS (UP) or MINUS (DOWN) button. The baseline value is 2007Y and is identified by a chirp.
  12. Press the STOP button (center button on the right side of the recorder) to set the time and date settings and close the menu.

The same entry procedure is used in the Timer Recording and Alarm functions.

How does the Zoom Mic option work?

The Zoom Mic menu option employs the DiMagic Virtual Microphone™ (DVM) audio pickup system, which allows more dynamic recording by focusing on sound from selectable directions. It enables expansive stereo recording to high directivity recording using the bundled ME55S stereo microphone, which plugs into the DS-61's MIC jack.

The options available in Zoom Mic are: OFF, NATURAL, WIDE, and ZOOM.

The Zoom option has the narrowest angle of reception and records only in monaural.

Because the DVM technology is tailored to the ME55S microphone, the ME35S microphone used on the DS-30, DS-40, and DS-50 is not compatible with DVM. Zoom Mic is non-compatible with Olympus accessory microphones and third-party microphones.

Will using an accessory microphone with an extended frequency range improve the quality of my recordings?

Using an accessory microphone with an extended frequency range may not improve the quality of the recordings in the DS-61. The recorder has an overall frequency response of 50 Hz to 19,000 Hz, but the different quality modes modify the detail of the saved file data by saving some frequencies and discarding others. This is how the recorder varies the potential recording time and uses the built-in flash memory more efficiently.

The table below shows the overall frequency response in the different quality modes:

Quality Mode Overall Frequency Response
STEREO XQ mode 50-19,000 Hz
STEREO HQ mode 500-16,000 Hz
STEREO SP Mode 50-9,000 Hz

I recorded a file and the battery ran out. Now I can't find or play the file. Why not?

When a recording session begins, a file is created to contain the incoming audio content. This file remains open throughout the session until the recording is manually stopped. If the recorder lasts longer than five minutes, the recorder will save the audio content at five-minute intervals.

If the battery runs out during a recording session, only the portion of the recording that has been saved will be available for retrieval. For example, if a recording session is interrupted by power loss at the 37th minute, the audio file of the recording will contain only the first 35 minutes worth of content. The remaining two minutes worth of content is not available because it was never saved to the file. In the case of recordings that are shorter than five minutes, the entire recording will be lost because the file is not able to close due to the lack of power. 

It is crucial to change the battery once the battery indicator shows only one hash mark of power remaining. Removing the battery while the recorder is in use may also corrupt a file.
