Recording
with Purevoice
Purevoice is an ideal choice for creating compressed audio recordings.
Using Qualcomm's CDMA technology, good speech quality is maintained
while using high levels of compression. Although nothing will
sound as clear and noise free as an uncompressed source, Purevoice
offers the ability to create very small files which are more easily
transmitted over the net. http://www.qualcomm.com/purevoice/

Purevoice Benefits:
- Press the ATTACH Record
button to attach a recording to an email account. This feature
is unavailable at the labs.
- Purevoice files saved in .qcp
format can be sent by email as an attachment provided they are
not over approximately 3MB.
- Purevoice files saved in .qcp format
can be saved to a floppy diskette provided they do not exceed
1.44MB.
Purevoice Shortfalls:
-
We do not recommend the Purevoice program for use in the
labs because it conflicts with the current lab setup. When
saving to the V drive, there is a known problem where
Purevoice will report an error that the file is in use or
cannot be saved. The file can be saved again and only if it
is overwritten will it save properly.
Although audio quality is satisfactory for hearing what is
being said, true audio quality is compromised due to compression.
More ambient noise will be heard, and the recording will not
be as clear as it could be.
- When saving a Purevoice file to a floppy diskette, the program
does not warn if there is insufficient space left on
the diskette, or if the file is too large to fit. The file appears
to be saved on the diskette, when in fact upon closer inspection
it is a 0k (empty) file. Always check that the file has been
saved by re-opening it and playing it back.
- When using the native .qcp format,
although compressed files are much smaller, this format requires
the Purevoice player be downloaded and installed in order to
play the .qcp files. The .wav
format however is common and can be understood by most media
players as well as CD Audio players.
Recording tips to ensure a good quality voice recording:
- Place the microphone on a flat surface 2-5 inches away from
your mouth
- Do not handle or breathe into the microphone as this will
create noise
- Record a short segment and play it back to hear how it sounds
- Adjust the microphone slider accordingly to avoid distortion
or a low signal
- Re-Record when you are satisfied with the optimal setup for
recording your unique voice
Submitting recordings to instructors by email:
- DO NOT save Purevoice files to the 'V - Voice Recordings'
area. If Purevoice must be used, submit the file by email as
an attachment using your personal email account.
- When recording an audio file students are required to record
their actual name at the beginning of each recording. The
filename should be the student name.
