Loading and saving Audio Files
If VoceVista Video Pro is already running, click on → to
open an existing file.
You can also drag files into the VoceVista Video Pro window.
In Windows Explorer, you can right-click on a file and select “Open with”
and then chose VoceVista Video Pro. You may have to click on “Choose
program…” if VoceVista Video Pro is not already listed.
Click on → to save a
recording. On the File Save Dialog, you can select the file type on the
bottom.
There are several keyboard shortcuts for saving files in a specific format.
VoceVista Video Pro can open most audio file formats. It can also open some
video formats and load their audio stream.
For saving, VoceVista Video Pro supports .wav, .ogg, .mp3, and .flac.
Wav files are uncompressed. Those files require the most
hard drive space, but they are also the fasted to open and save.
The other three formats are compressed, so they all produce smaller files
than .wav. For compressed formats, one distinguishes between lossy and
lossless compression. Flac is a lossless format, which
means that when a recording is saved as a .flac file and then loaded
again, the reloaded data will be exactly what it was before. This perfect
quality comes at a price, however, because the compression is usually not
more than 50% compared to an uncompressed wav file.
The formats .mp3 and .ogg use lossy
compression. When a recording is saved in these formats and then loaded
again, the restored data will be different from the original and
depending on the strength of the compression, more or less detail will be
lost. However, this enables much higher amounts of compression than the
lossless formats. Files saved as .mp3 or .ogg are often 90% smaller than
a .wav file with the same data.
You can specify the amount of compression if you have selected one of
those file types and press the Options button on the Save File Dialog.
Mp3 is the most popular format for compressed audio files. Ogg is a newer
format that has been designed to replace mp3. It claims to have a better
sound quality for files of the same size.
While you are editing a sound file, it is recommended to save it in the
.wav format to avoid losing quality from compressing and uncompressing
the file many times while it is opened and saved again. When the file is
ready for archival, save it in .flac if you need perfect quality, or save
it in .ogg if you want smaller files and can accept a certain loss in
quality.
