5. E-mail headset control box functions
Control box has 2 buttons (“Microphone”) and (“Ear”) and headphones volume control . The actual function of
each button is determined by the software driver (EHSMonitor). The volume control is used to adjust the hardware loudness of the
headphones. It has no influence on the system software volume control.
6. EHSMonitor software manual
6.1 Software overview
6.1.1 EHSMonitor
With EHSMonitor it is possible using only one button to record file, save it, convert to MP3 and even to generate an e-mail
message with the recorded file attached or upload record to web server.
6.1.2 LAME MP3 encoder
MP3 is a format for compressed audio storage. MP3 uses psychoacoustic filters to remove sounds that are inaudible to the human
ear, as well as other methods to compress the audio information. Thus there could be discernable difference between the original
and encoded audio data (a great depends on the encoding parameters). Modern MP3 encoders are very flexible and allow you to
set a lot of parameters, affecting the encoding speed and the output file quality. EHSMonitor uses LAME as default encoding
engine. LAME is quite fast (encodes faster than real time on a PII-266 at highest quality mode) and provides a very good sound
quality. For more information, please visit LAME official site at http://www.mp3dev.org. If for one or another reason you do not
like LAME, you can use any other MP3 encoder that supports command line interface. See “Advanced settings” section for
details.
6.2 E-mail microphone recording
6.2.1 Recording
E-mail headset allows you to record and E-mail sound files by pressing only one button. The rest (MP3 encoding, generating of
the eMic-message, uploading it to the eMic4all server etc.) will be done for you automatically. Recording is always first made to a
temporary file. Thus, even if the recording is finished abnormally (power failure, etc.) the recorded data would not be lost
(however such file would not be recovered automatically). It is possible to assign one of five pre-defined functions to any of the
microphone buttons (since it is assigned, it becomes a function of E-mail headset). That means that it is even possible to assign the
same function to the both E-mail headset buttons. There are two ways to use the E-mail headset buttons:
Hold down. Recording starts right after the button is pressed down and lasts while the button is held pressed. When the button is
released, recording stops.
Click. Recording starts after the button is pressed and consequently released. Recording stops when the button is pressed for the
second time. Recording can be paused and resumed as many times as needed by pressing and releasing the button different from
the one that has started the recording.
Page 4
The five pre-defined functions are:
Rec. If MP3 recording option is set the recorded file is encoded to mp3 file format.
Rec and Attach. After the recorded file is saved (and encoded if necessary), an e-mail message is generated with the recorded file
attached. It just remains to specify the recipient and send the message.
Rec and save to specified file or MEMO function. When the recording is finished, EHSMonitor prompts you for the recorded
file name. If specified, the recorded file is encoded to mp3 file format.
Rec and upload to eMic4all server. Encoding to mp3 and uploading to the server is being processed during the recording. After
the recording is finished the link to the eMic-message on the server is generated and immediately pasted into the window that had
input focus at the beginning of the recording.
Note: Rec and upload function is available for the Wav and normal quality Mp3 recordings only.
Note: Normally by default a defined by you text (prefix) precedes the link to the eMic-message. If the prefix text is not required
(which e.g. can be useful if you intend to insert the link into Excel file or database) push the Shift key just prior to the moment
when you start the recording.
Rec Skype/MSN. Records Skype, MSN, Windows Live Messenger or other VoIP software voice conversations. During the eMic
installation Skype and MSN will be automatically configured for this function to work. If you install Skype/MSN after the eMic or
if you use a different VoIP software for the voice communication, make sure that the virtual device named eMic Audio Filter 1
(Windows XP) or Line 1 (eMic Audio Filter) (Windows Vista) is selected as the input microphone and the virtual device named
eMic Audio Filter 2 (Windows XP) or Line 2 (eMic Audio Filter) (Windows Vista) is selected as the output sound device in the
settings of the Skype/MSN/VoIP software.
Note: Rec Skype/MSN function is available for Windows XP and Windows Vista only.
Undefined (Unused). The button will not be used by the EHSMonitor software. This can be helpful is some other software uses
this button.
Filter. With this option set, before the eMic-function is executed the selected sound filter will be applied to the recording. Use
Sound editor to edit and create your own sound filters.
Note: Filter option applies to the currently selected pre-defined function.
Sound editor. With this option set, before the eMic-function is executed the Sound editor will be launched. With the help of the
Sound editor you will be able to listen to your recording and edit or amend it if necessary.
Note: Sound editor option applies to the currently selected pre-defined function.
MMAB. With this option set, every time creating an e-mail with Rec and attach eMic-function you will be offered to choose the
recipient from multimedia address book.
Note: MMAB option applies to the currently selected pre-defined function.
Note for Windows version: All settings changes come into force only after the “Apply” button at the bottom of the dialog box
window is pressed.
6.2.2 Managing recordings
After the recording has been finished, the recorded file name is saved in the list of all recorded files. EHSMonitor allows to change
the file name or location (the file will be renamed and moved if necessary), to delete one or more files or to generate an e-mail
message with one or more previously recorded files attached. See “Recording manager” section for details).
6.3 General settings
6.3.1 One-touch recording options
Save recorded files Specifies the folder where the recorded files will be saved to. You can select any existing folder.
Wav/Mp3/HQ Wav/HQ Mp3 radio button. You can also select one of the four formats to save the recorded data.
“HQ Wav” and “HQ Mp3” formats has higher sound quality then “Wav” and “Mp3”, but less compact file sizes (by a factor of 2
and 1,5 respectively). Formats are described in the table below.
Table 1. Audio file formats.
Designator Audio file format
Wav Wave PCM, 11,025 kHz 16bit mono
Page 5
Mp3 MPEG Audio Layer-3 16kBit 11,025 kHz
HQ Wav Wave PCM, 22,050 kHz 16bit mono
HQ Mp3 MPEG Audio Layer-3 VBR 8-24kBit 22,050 kHz
6.3.2 Button A/Button B function
E-mail headset has five different functions. Any function could be assigned to any of the buttons; it is even possible to assign the
same function to both buttons. See “E-mail microphone recording” section for details.
6.3.3 Launch at Windows startup (Launch at user login)
If this option is set the EHSMonitor will start automatically whenever the Windows is started (on user logon for Macintosh users).
6.4 Advanced settings
6.4.1 External MP3 encoder
By default EHSMonitor uses LAME encoder to encode to MP3 and the default format is CBR 16Kbps, 11025 Hz, 1 channel
(mono). If you would like to change from LAME or if you want to specify the custom encoding parameters, you can choose any
other encoder (here and later - external encoder) you like. There is only one requirement: the external encoder should support
command line interface, i.e. it should be possible to use it from the command prompt.
Use External MP3 encoder By checking this check box; you can make EHSMonitor use any external command-line MP3
encoder instead of the default encoder.
Path to executable Specify the full path to the external encoder executable file. You can enter the path manually in the edit box or
browse for the file. If the invalid path is specified in this field, EHSMonitor will attempt to use its own encoder. If for some
reasons the built-in encoder cannot be used as well, then the file will be saved to the same folder and with the same name but in
the “wave” format (and with .wav extension). So, whatever happens, your recording will not be lost.
Additional parameters Specify any additional parameters, supported by the external encoder. These parameters are passed
directly to the encoder exe-file without any check if the external encoder really supports the specified parameters.
Generally, the external encoder call string should satisfy the following template:
<full path to encoder> <additional options> <full path to source file> <full path to
destination file>
Parameters are described in the table below.
Table 1. External MP3 encoder parameters.
Full path to
encoder
Additional
options
Full path to
source file
Full path to
source file
Warning! If encoding fails due to the invalid path to the destination file, or due to the invalid additional options (not supported by
encoder), the original recorded wave file will be deleted. Unless you are able to supply the correct external encoder parameters, it
will not work. In general it is quite enough to use the LAME encoder, supplied with EHSMonitor.
The full path to the external encoder executable file.
Any additional options.
Full path to the source wave file. Supplied by EHSMonitor. User does not have to care about this
path.
Full path to the destination mp3 file. If supplied by EHSMonitor , it is always valid. If this path is
supplied by the user, the user is responsible for validity of this path.
6.4.2 File name format for one-touch recording
Names for the files recorded with one-touch recording are generated automatically based on the user-defined template. The
generated file name looks like this:
<Prefix><Random number>.<extension>
Parameters are described in the table below.
Table 2. File name format parameters.
Prefix An arbitrary string. This string can’t include system characters (such as backspace character, new
line character, etc.) and any character from the following set: < > : " / \ |.
Some This is the part of the file name, which makes files different from each other. This number can be
Page 6
number generated in two ways.
Date/Time based – the generated number represents date and time when the recording is finished,
using the following template YYYYMMDDhhmmss, where letters "YYYY", "MM", "DD", "hh",
"mm", "ss" represent current year, month, day, hour, minute and second respectively.
Enumerated – numbers are generated consecutively, i.e. the generated number is the least not
used number (there is no file with the same filename), starting from zero.
Extension File extension. "Wav" or "mp3" depending on the selected file format.
6.4.3 Advanced recording options
EHSMonitor sets the minimum recording time. This means, that any recording, that lasts less than minimum recording time is
discarded. This can be useful to eliminate recordings caused by accidental EHS button pressing. By default the minimum
recording time is 1 second. The minimum recording time can be any number in the range from 1 to 262144 (3 days 49 minutes 4
seconds). The maximum recording time is limited only by the available hard disk space.
6.4.4 Address book options
Use multimedia address book. When this option is checked every time creating an e-mail with EHSMonitor using Attach
selected files button you will be offered to choose the recipient from multimedia address book. Use Edit... to run Multimedia
address book editor to form list of contacts.
Note: Any changes made to this setting will take effect only after the current recording is finished (if any).
6.5 eMic4All account settings

Note: even if Preview option is not selected an icon will appear in the system tray for one minute after the recording is
finished. Double-click on this icon to launch the Upload properties window.
Note: if by the time you finish the recording the document in the active window does not accept entering of the text, the link to
the eMic-message will not be inserted there. However the whole link will be stored in the Clipboard. Use Paste function (Ctrl-V)
to place the link wherever you wish to.
6.6 Recording manager
6.6.1 Recording manager
EHSMonitor maintains the list of all recorded files and links to their remote copies stored on the eMic4all server. If the eMicmessage has a title it is also displayed next to the file name. Any time you make a new recording the recorded file is added to the
list. Uploaded records are marked with a special icon . Using the recording manager you can manage your recordings: rename
them, generate e-mail messages with one or more recordings attached to them, upload records to the eMic4all server, delete
recorded files or their remote copies on server, you can also edit your records using the Sound editor including updating stored on
the server eMic-messages and their appearance.
To generate an e-mail message with some recordings attached or to delete some recordings, select them in the list and click Attach
selected files or Delete selected files button respectively.
To edit a record, no matter uploaded or not, click Edit button. If for the currently selected record there exists an eMic-message
uploaded to the server, eMic-message properties window will appear.
Click Copy link button to copy a link to the uploaded eMic-message to the clipboard.
You can click Upload button on the locally made record to create an eMic-message on the eMic4all server.
Use Refresh button to update status of the selected records. If the eMic-message cannot be found on the eMic4all server a special
icon will disappear from the record row. The eMic-message titles will also be updated from the server.
To rename a certain recording, select it in the list, click on it and edit the file name (location).
The double click on the file in the list will cause this file to be played or opened by the default application that is assigned to
handle this file extension. In fact the double click on the file will have the same effect as executing this file from the Windows
Explorer.
Note: it is also possible to play back the records from synchronization window.
6.6.2 Synchronization
To synchronize all locally stored files and the eMic-messages on the server press Sync button. This button will update all the
titles of the eMic-messages. In addition to it a synchronization window will appear when:
a) one or more records which are supposed to be on the eMic4all server but cannot be found there (so probably need to be
uploaded again)
b) one or more records which do exist on the eMic4all server but the local copy is missing (so probably need to be downloaded
again)
c) one or more records which cannot be found neither on the eMic4all server, nor locally (such records have to be removed).
The synchronization window is intended to help you keep your recordings synchronized with the eMic-messages on the server.
The three first columns in the table indicate which action should be taken with the “troublesome” record. At the same time the
icons in the first two columns show the status of the local record and of the eMic-message.
The green tick in the first column means that the locally stored record has been found. The empty space in the first column
means that the locally stored record on the server is missing.
Page 8
The green tick in the second column means that the eMic-message record on the server has been found. The empty space in the
second column means that the eMic-message record on the server is missing.
You can specify the action to be taken with each record. The possible actions are:
1. Upload local record to the server – represented by the symbol
2. Download the record from the server – represented by the symbol
3. Delete the record – represented by the symbol
When the window is opened for the first time the system by default selects the most logically correct action for each record. This
default action can be changed by clicking on the cell.
All the actions will be performed immediately after you press the OK button.
6.7 Troubleshooting (Solving problems)
Common problems and solutions:
· External MP3 encoder does not work
The external MP3 encoder call string is the following:
<executable name> <additional parameters> <full path to source file> <full path
to destination file>
Be sure that your encoder would accept this string.
7. Multimedia Address Book utility
