Just wishing Voxengo happy holidays. Also I can not thank you enough for the free DLs, friends & clients are blown away from the quality of my mixes. I am definately going to purchase all of the products I need from Voxengo in the future. Happy holidays from Joe at Big Dummy Recording
This utility program was designed to allow both amateur and professional users to perform high quality sample rate conversion of WAV files. For example, if your WAV file was recorded or saved as 48000 (or 96000) file and you need it to burn onto a CD you will likely need to convert it to 44100 before that. This utility will help you to perform such conversion. r8brain also supports batch processing which is essential if you need to transfer all your project's audio data from one sample rate to another. Programmers can use standalone converter DLL in their programs free of charge.

Batch processing
Writes 8, 16 and 24 bit PCM WAV files and 32 bit IEEE WAV files
Reusable royalty-free converter DLL with explained API
Requirements
Windows 98 or any later Windows OS
About 570 kB of harddisk space
For best performance a fast processor is required
What's New
Version 1.9, 26-aug-2005
Various issue fixes.
Version 1.8, 11-dec-2004
Issue related to processing files via network fixed.
Version 1.7, 18-jun-2004
Batch mode checkbox display bug fixed.
Console sample rate converter added.
Version 1.6, 26-may-2003
Resampling filtering curves were improved.
API now has two new functions.
Now "resample to" sample rate can represent any fractional number (e.g. 22050.5 or 44100.32).
Now a different output sample rate which will be written to the WAV file header can be specified.
Directory batches can be processed recursively.
Version 1.5, 20-oct-2002
Maintenance release.
Version 1.4, 13-oct-2002
Changed batch processing file renaming scheme. Now converted file will have original file's name and original file will be renamed (or deleted).
Version 1.3, 6-oct-2002
Slightly boosted converter speed (by nearly 6%).
Version 1.2, 14-sep-2002
Fixed bug in implementation of dithering. Now dithering also incorporates a slight noise-shaping.
Once again low-pass filering was untightened a bit. Now huge downsamples (like 96000 to 44100) sound much softer.
API has changed: Preallocate parameter was Boolean now LongInt, CancelFlag was Boolean now LongInt. A new API procedure added.
Batch processing implemented.
Added 64-bit floating output format.
Version 1.1, 10-sep-2002
Huge internal resampling procedures rewrite. Now r8brain can be considered fast sample rate converter.
r8brain now supports only stereo and mono WAV files.
Memory requirements were lowered a bit.
Low-pass filtering was untightened a bit in order to increase perceived quality.
Changed default quality to 'Medium'.
Output sample rate edit box was changed to drop down list for easier sample rate selection.
Implemented better support for 'nonstandard' bit depths like 20, 14, etc.
