Digital Recording: A
Primer
Transcription
costs and turnaround time have dramatically decreased, thanks
to digital recording. Instead of using a tape recorder, you
can now record using your computer or a digital recorder. This
way, you can upload the audio file (MP3, WAV, etc.) to us
instantaneously. And there are additional benefits of digital:
-
Because digital
recorders contain no moving parts that can produce
background noise, such devices typically produce superior
sound quality to that of cassette recorders.
-
With digital there is continuous
recording; by contrast, you have to flip tapes periodically,
in which case you could miss crucial things being said.
-
It is easy to make multiple backup
copies of digital recordings; whereas with tapes you only
have one copy. If you need to send your tapes to be
transcribed and they get lost in the mail, you're out of
luck.
Recording With
Your Computer
The best way to record is to simply use your
computer equipped with a good, external microphone; this achieves the highest
sound quality. Of course, if you're in the field, it will need
to be a laptop. While your computer probably already comes
equipped with recording software, we recommend Polderbits software for in-person
recordings. (Save the file in MP3 format, since this takes up
much less space than regular WAV
format.)
Important Note: To ensure against minor and inevitable
disasters, always use two recording devices simultaneously -
one principal and one backup. For example, in addition to
recording directly to your computer, record with an external
digital recorder (see below), or at least with a traditional
cassette recorder.
Recording Phone
Calls
To record phone calls, we
recommend running your phone line through your modem and using
CallCorder software, which achieves
superior sound quality. Use an external digital recorder (or a
traditional tape recorder) as a backup. Note that CallCorder
is not compatible with all modems, so make sure yours is
compatible before you buy.
Note: Always inform the other party that you are recording.
Even if recording without the other party's consent is legal
in your state, get their consent anyway as a courtesy. For

Using an External Digital Recorder
Another simple way to record digitally is to purchase
an external digital recorder that allows you to upload your
audio files to your PC. If you do not have a laptop, this is
the next best option while in the field. For enhanced sound
quality, we recommend using an external microphone rather than the
device's built-in one. And be sure to place it as close as
possible to the principal speaker.
Olympus (along with many other electronics
manufacturers) makes several digital recorders; the DS2200 is said to produce the highest
sound quality. A significantly less-expensive device is the DS330. The VN-480PC,
meanwhile, is available at Radio Shack for about $100-$120; if
you buy it, be sure to get the VN-480PC and not the VN-480.
To record phone calls with an external digital
recorder, you will need a recorder control. But as mentioned
above, use CallCorder software (see above) as your primary recorder, while using the
external recorder as a backup, since the sound quality of the
former is superior.
Once your recording is complete, consider changing
the name of the file to something that easily identifies the
recording (such as "john.MP3"), and upload it to our site via the above
link.
Non-Uploadable Digital Recorders
If you have an external digital recorder that does not
allow you to directly upload files to your PC, you can
transfer the audio recording to your computer using the audio
cable method described below. While your recorder is connected
to your computer via an audio cable (plugging one end of the
cable into the recorder's earpiece input jack and the other
end into the computer's sound card), you'll need to play the
length of the recording in order to do the transfer.
Converting a Cassette Recording to Digital
If you do not yet have a digital recorder,
another option is to record with a normal cassette tape
recorder and then transfer it to digital. (To record phone
calls using a tape recorder, you will need a recorder control
- see above.) If you choose this route, after completing the
recording, connect your tape recorder to your computer's sound
card with an audio cable
(with a 1/8'' plug on both ends). One end of the cable
should be plugged into your tape recorder's earpiece or
headphone input jack and the other end into your computer's
"line-in" input jack on the sound card.
To transfer it to digital, open Polderbits.
Simply play the length of the tape recording while
running Polderbits, using the "line-in" option (or if that
doesn't work, try the "microphone" option). Save it as "FM
radio quality," and as an MP3 file (since MP3 files take up
much less space than WAV files) at 48 kb/sec.
We don't
recommend playing the length of your tape recording into your
computer's microphone (as opposed to using an audio cable),
since the audio quality of the newly created digital file
likely will be poor. Or, you can simply send the cassette
to us via regular mail.
Consolidating/Zipping Together Multiple
Files
If you have many audio files -
especially if you have dozens of small files - before
uploading them to our server, we recommend zipping them
together by using a program such as WinZip. That way you don't have to
upload them one by one. Or, simply use our alternative batch
upload site.
