Vox Studio converts any file format it knows to any other file format it knows. This includes the capability to change the sampling rate (downwards and upwards) as well as the coding or compression algorithm.
You can, for instance, convert a 44.1 KHz ".wav" file into a 6 KHz ADPCM file or convert a Mu-law PCM file at 8 KHz into an A-law PCM file at 8 KHz. You could even do unusual operations, like converting a 6 KHz ADPCM voicemail file into a 22 KHz ".wav" multimedia file. This would, for instance, allow you to review voicemail files on a normal PC running Windows.
The amplitude of the recorded signals is left unchanged by the conversion processes. You can, however, elect to activate the "Normalize Sound Volume" option during conversion. This gives you the ability to do post-recording amplitude adjustments. You can also apply a variety of filters during conversion. Conversion and filtering of files can be done in one step. Vox Studio does all the filtering that is necessary for sample rate conversion transparently and you do not need to apply any pre or post-conversion filters.
See the chapter on Sound File Formats for a complete summary of what files Vox Studio can record, play back, convert or otherwise manipulate.
See the Convert menu chapter for more information on how to convert files.
