Chapter 5 Recording and playing

5-1. Specifying Wave Formats

Before recording a wave file, make sure the correct format
of the file is specified. Wave format refers to the sound
channel, Sampling Rate and Size of the file.

To specify the wave format:

1. Select

Record Setting

Choose Wave Format

2. Select the format for the wave file.

in the

Options

menu and

dialog box appears.

23

Select Mono for one sound channel and Stereo
for two sound channels.
Select 11025Hz for voice, 22050Hz for cassette
and 44100Hz for CD quality recording.
Select 8 bits for cassette and 16 bits for CD sound
quality.

3. Choose OK.

There is a trade-off between the quality of a wave file
and the amount of storage space required for the file.
A wave file with better sound quality requires a larger
storage space because of its high sampling rate. The
message in the dialog box will inform you how much
free disk space is available for recording.

Chapter 8 Warning signs

8-1. Warning signs appear during installation

7-1-1 If your sound card is not installed properly or
wave device is being used by other applications , the
following warning sign will appear during installation.

32

8-1-2. If the following warning sign appears when you
are running the software then

Sound card has not been installed in your PC.

Recording and playing function of wave device

is used by other application software.

Explanations of the above warning signs:

The digitizer will only operate when the sound
card record function is running. If the record
software doesn’t operate, it is impossible for the
LR Volume Indicator to display the volume.

8-2. Questions when you are using the software of

33

DSB-R100.
(A) I am running the DSB-R100 software, but I can't

hear anything. What should I do?

ANS:

If your software is already running and you can

z

operate the control panel switches, this shows that
the radio has been installed correctly. If this is not
the case, then the radio receiver/recorder is not
operating properly and you should make sure that
the DSB-R100 Adapter has been installed properly.

If you still can't hear anything even though the

z

DSB-R100 is operating normally, one of the
following situations may be occurring:

A. The RCA jack may not be correctly inserted in

the sound card's Line In socket. Please make
sure it is inserted correctly.

B. The sound card's "Line In" volume may be set

on mute or at the lowest value. Adjust the
volume dial and the mute switch on the right
side of the control panel until you are able to
hear sound. (If adjusting the volume dial has no
effect, you can try opening the Windows 95
Mixer and making adjustments from there.)

C. A problem with the sound card driver may be

making it impossible for the DSB-R100's signal
to enter the computer. Please re-install the driver
software that came with your sound card.

D. If the volume indicator on the control panel is

blinking but no sound is heard, please see the
answer to question B.

34

(B). My DSB-R100 's volume indicator is blinking

normally, the switches are all functioning properly,
and the speaker is on, but I don't hear anything.
Why is this?

Try turning off the volume indicator. If you are then

ANS:

able to hear sound, this shows that the sound card was
unable to transmit sound to the speakers while it was
recording a WAVE file. The solution is to turn off the
volume indicator. The reason for this is that the
DSB-R100 must turn on its record function when the
volume indicator is turned on (see question 10 for an
explanation). Another solution is to open Win95's
Mixer (double click on the speaker icon in the lower
right part of the screen to open the Mixer) and change
several of the special record options on the record page;
see if you can simultaneously hear sound and cause the
volume meter to appear. For example, if you use the
ESS sound chip, it should be possible to find the volume
monitor switch in the mixer control program; turning on
this switch will generally solve this problem.



Testing throughout the design process has proven

that the DSB-R100 is completely compatible with
most sound cards on the market.

35

Deleting the check mark will close the volume meter

(C). I can hear sound from my DSB-R100 , but the

volume indicator doesn't move.

ANS:

The volume indicator is able to display the volume

because the radio's sound output is run through a
digitizer and then displayed on the screen. Since the
digitizer will only operate when the sound card's record
function is running, if the DSB-R100 software cannot
operate the sound card's record function, then it will be
impossible for the volume indicator to display the
volume.

36

The following are some possible reasons why the volume
indicator will not move:
A. The volume indicator cannot move because the

sound card is already recording (for instance a
multimedia program is in the midst of recording) or
is already playing (see if you have a simplex or a
duplex sound card).

B. Your sound card driver is not installed properly and

other multimedia programs are also unable to use
the record function. In this case the DSB-R100 will
certainly be unable to record or display the volume
level.

C. Because the earphone's RCA wire is not properly

plugged in to the sound card's Line In socket, the
volume meter can't move and you can't hear any
sound either.

D. You haven't turned on the volume meter (set from

the Options menu as shown above).
E. The final reason is also the most important:
The source of the sound to be recorded has been

selected incorrectly. In theory, sound output from

the DSB-R100 will go to the sound card's Line In,

and the source of sound to be recorded should also

be the Line In. Only then will sound from the radio

pass through the recording and digitizing unit and

be displayed. But if Line In (Line) has not been

selected as the sound source, then the sound card

won't receive input from the radio, and the volume

meter won't be able to function normally. However,

because we took this into consideration when

designing the DSB-R100 software, this situation

should seldom occur. Whenever you run the

37

DSB-R100 software, it will automatically select the

Line as the sound source. To insure that the situation

mentioned above doesn't make it impossible to view

the volume, we have made our software compatible

with most sound cards on the market. But if this

problem does occur, there is a solution you can try:

This solution is to manually change the sound

source as follows: Open the "Volume controllers

settings" under the DSB-R100 software's "Options";

you will see the following screen. Change the

settings to resolve the above mentioned problem.

38

(D). Why is it that the volume dial on the right side of

my DSB-R100's screen sometimes doesn't move
and sometimes moves but doesn't have any effect?

ANS:

A. As described above, the volume control settings

may be incorrect. You should use the method

described above to change the settings.
B. Another possible cause is incorrect sound card

driver software.

(E). Why can't I use my DSB-R100’s record and play

functions?
ANS:

A. Other applications software may be currently using

the record or play functions. It is then impossible for

the sound card to run the record unit again.
B. Your computer doesn't have a sound card.
C. Your computer has a sound card, but the sound card

driver hasn't been installed correctly.
