| Audio
Record Controls |
Use this
button to open your Windows Sounds and Audio Devices Properties.
When you are setting up hotComm, make sure that the things you plan
to use are displayed:
1. Click the Audio
Record Controls button.
2. Select Options, then Properties.
3. In the Properties window, make sure that Microphone
is checked. If you plan to play sound files, also make sure that
Wave Out or Wave Out Mix is checked.
4. Click OK.
Note that you can also open
Sounds and Audio Devices Properties through your Windows Control
Panel. |
| Balance |
If your recording
device has left and right inputs, you can adjust the balance. Note
that this is grayed out for many microphones, because they have only
one input channel. |
| Mic
Threshold |
To change the volume
level at which the sound transmission is triggered, select a
Threshold level. A lower threshold means that hotComm will start
sending audio when it detects quieter sounds than it would with a
higher threshold setting.
If the presenter's audio seems to come and go, the presenter might
try lowering their threshold level. |
| MIC
Pre-Boost |
If your audio card
supports a microphone boost option, you can check the MIC Boost
checkbox to enable it. MIC boost enabled may increase volume, but
may also cause audio problems for your listeners. Experiment to find
the best solution for you. |
| Noise
Filter |
To filter out
background sounds and other unnecessary noise, check this option. |
| Input
Peak Meter |
Display a
colored input meter when your mic is on. You can use this to confirm
that hotComm is receiving audio through your mic. The Input Peak
Meter appears on the bottom line of your iConference window, and
looks like this:
 |
| Device |
Select which input
device you want to use as a microphone. If your computer is set up
for multiple input devices (such as a USB mic and a sound card), you
can select which one to use.
iConference attempts to use the device defined as your Windows
system default.
As a general rule, use the same device defined to Windows. To see
which device is defined to Windows:
1. Click the Audio Record
Controls button.
2. Select Options, then Properties.
3. In the Properties window, it is the device shown as Mixer
device.

Play a recorded
WAV file at the beginning of the session.
Enter the name and location of the WAV file in Intro WAV file,
or click the browse button [...] to find the file.
Presenters may choose to start a session with an Intro WAV file,
so that attendees can test and adjust their audio. When the
Presenter is ready to speak, the Presenter changes the Source
from Intro WAV to Microphone. |
|
| Note: the
microphone icon changes according to your source selection: |
|

|
Auto-Select |
While
your iConference mic is on, your Source selection becomes your
default Windows input device. This affects all applications that are
running.
When you turn your iConference mic off:
- If Auto-Select is checked,
iConference restores your previous Windows input device setting.
- If Auto-Select is not checked,
then your iConference selection becomes the default Windows input
device.
|
| Quality |
Select an audio
compression level, to control the clarity and resolution of the
sound itself. Level 1 has the lowest compression, and therefore the
lowest quality. Choose the highest level that provides good audio
for your listeners.
- Levels 1-5: audio is sent at
8kHz, with increasingly higher compression and resolution.
- Level 6: audio is sent at 16kHz.
- Level 7: audio is sent at 32kHz.
You can pre-set these levels on
your iConference startup command line, with the /p option.
Although any level can be used for voice or recordings, the
following are recommended:
| Levels |
Recommended
for... |
|
1-4 |

|

Playback Properties
These settings control what you hear: |
|
Setting |
Description |
| Volume |
To change your
playback volume, move the slider up for louder, down for softer. |
| Balance |
Move the slider on the
Left-Right horizontal scale until the sound is balanced correctly
between your left and right speakers. |
|
Pre-Buffer |
This setting controls
how many sound packets are grouped together before they are played.
If parts of words or phrases are being cut off, or the sound seems
choppy, increase the pre-buffer setting.
There is no rule about what setting will be right for you. You may
need to change the Pre-Buffer setting for different situations. The
best setting is the lowest one that still gives you smooth,
uninterrupted sound. |
