When I am playing a file all I hear is loud noise
You may be playing a file in a format unsupported by Vox Studio. If not, somewhere
in the production or playback process, the wrong file format was indicated to Vox
Studio. You may, for example, have told Vox Studio to play a file as ADPCM while
in fact it contains A-law coded sound. An error may also have occurred in an
earlier stage. For instance, when you converted the file, a wrong source or
target format may have been selected.
Vox Studio does not play my file, other utilities do
You probably forgot to set up your sound devices in the "Defaults" menu.
Vox Studio allows you to select the sound card you want to use (for those who
have more than one sound card).
The file plays noticeably too slow or too fast
Somewhere in the production process or during playback you have indicated a wrong
sampling rate to Vox Studio. For example, if you have produced a telephony file
with an 8 kHz sampling rate and are playing it back at 6 kHz, the file will play
back too slow.
Do you have a version that supports long filenames?
Yes, we do. Vox Studio version 3.0 and later is a full 32-bit version and was
designed to work with Windows 95, Windows 98, NT4 and Windows 2000. It supports
long filenames and long directory names. If you need this feauture you should
upgrade to the latest version.
Vox Studio cannot open my WAV file
Are you sure your file is in "linear PCM" WAV format? There are hundreds
of different WAV file types (they all have the same WAV extension) and we support
the most common format used by 99% of all WAV users. Also make sure your sound
card can handle mono files (stereo files are useless in telephony).
The telephony files sound muffled
This is not unusual if you have converted to a file format with a very low
sampling rate (8 or 6 KHz). Try the "Intelligibility Filter" option in
the conversion dialog box. Settings for the intelligibility filter are in the
"Defaults/Miscellaneous" menu. Try setting the "Clarity"
I have problems under Windows 2000
You may be using the 16-bit version of Vox Studio. For Win 2K support you should
upgrade to Vox Studio version 3.0 or later.
I am always asked for the file format
Unfortunately most telephony file formats contain no information as to the file
coding used inside the file itself. You just have to know which format and
sampling rate is used in every particular file and you have to tell this to Vox
Studio. If you often use the same telephony format, you can simplify your work a
lot by setting this format as the default source or target format in Vox Studio
(using the Defaults menu).
Some newer telephony file formats have a header with a signature at the beginning
of the file. This enables Vox Studio to know what file coding and sampling rate
to use. If that is the case, Vox Studio always uses this information
automatically and never prompts you to enter the information if it exists.
16 bit or 8 bit wav files
There is no discussion here. Use a resolution of 16 bits for your original
recordings. This is 256 times better than a resolution of 8 bits. We only added
support for 8 bit files for those unfortunate users who have a very old 8-bit
sound card and cannot afford to install a newer one. Unless you absolutely need
to use 8 bits, we strongly suggest you even forget it is available.
I want to resell and give Vox Studio an OEM look
Vox Studio resellers and volume customers can display their own logo in the Vox
Studio main window. Vox Studio resellers can also show an additional menu item in
the Vox Studio Help menu. If a web browser is installed on the same machine as
Vox Studio, this new menu item will open the reseller's custom html page. Volume
customers and resellers should contact Xentec directly for more information on
implementing these capabilities.
I cannot process long files
The free Vox Studio demo version (unregistered version) limits the length of the
processed files. When you purchase a license for Vox Studio you get a license
number and a registration key which allow you to transform the demo version into
a fully registered one. There is no limitation on the length of the files or on
the number of files handled in the registered version.
I am writing an application, can I use Vox Studio conversions?
Yes. There is a file conversion DLL which you can use when you buy Vox Studio and
there is also a command-line interface. Contact Xentec for more information on
how this works.
