control for lowpass, highpass, and resampling filters.
Added \"new rate\" audio filter to relabel an audio
stream with a new sampling rate without resampling.
Incomplete audio format headers that are rejected by

Fixed garbage wLanguage/wPriority values being written

About:
VirtualDub is a video capture/processing utility for 32-bit Windows platforms (95/98/ME/NT4/2000/XP), licensed under the GNU General Public License (GPL). It lacks the editing power of a general-purpose editor such as Adobe Premiere, but is streamlined for fast linear operations over video. It has batch-processing capabilities for processing large numbers of files and can be extended with third-party video filters. VirtualDub is mainly geared toward processing AVI files, although it can read (not write) MPEG-1 and also handle sets of BMP images.
An exciting history of VirtualDub startup can be found here.
