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

i.e.

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.

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.

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.

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: < > : " / \ |.
