4.3.1. Loading and saving Audio Files
If VoceVista Video is already running, click on→ to open an existing file. You can also drag files into the VoceVista Video window. In Windows Explorer, you can right-click on a file and select “Open with” and then chose VoceVista Video. You may have to click on “Choose program…” if VoceVista Video 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 can open most audio file formats. It can also open some video formats and load their audio stream.
For saving, VoceVista Video 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.
If you want to save files in the .mp3 format, you have to first install the Lame mp3 encoder dll.
To create Mp3 files with VoceVista Video, the LAME Encoder (lame_enc.dll) needs to be installed on your computer. Since Mp3 is a patented technology that requires an expensive license, we cannot distribute this file ourselves and recommend the use of the Ogg file format for creating compressed audio files. Ogg is a free alternative to Mp3 that also claims to have a better sound quality than Mp3 for compressed files of similar size (http://en.wikipedia.org/wiki/Ogg).
If you want to create Mp3 files, there are a number of sites where you can freely download the LAME Encoder. For example: www.rarewares.org.
If that link doesn’t work, you could also go to the official LAME website and look at their links section or try a web search.
Please be careful when downloading software from the Internet. We are not in any way affiliated with rarewares.org, or any other site that distributes the LAME encoder, we have absolutely no control over what is offered there, and we cannot guarantee the safety of files offered by them. Use files from these sites at your own risk.
To use the LAME Encoder, put lame_enc.dll somewhere on your computer. When you want to save a file as mp3 in VoceVista Video, browse to the location of the lame_enc.dll when VoceVista Video asks for it during the saving of the file.
