discWelder Bronze Basic DVD-Audio Tool
Minnetonka Audio Software has recently announced their new discWelder BRONZE product, a basic DVD-Audio authoring program that for the amazingly low price of $99 allows users to create high resolution surround recordings on DVD-recordable media. Stereo PCM tracks can be as high as 24-bit/192 kHz and 5.1 surround recordings can be as high as 24-bit/48 kHz. Both WAV and AIFF file formats are supported. We installed the discWelder BRONZE software on our Sony PCV-RX550 equipped with a Sony DRU-510A DVD±R/W drive. Installing the software is simple, yet requires users to register their software within 14-days to be able to continue using it after that period. Currently, the software is only available for Windows 98/2000/NT/XP. However, a beta version for the Mac has recently been released for testing.
The discWelder Bronze software does not support Meridian Lossless Packing (MLP), which is required for 24-bit/96 kHz (24/96) and 24-bit/88.2 kHz (24/88.2) tracks in the 5.1 surround mode due to bit rate limitations (9.8Mb/s) of the DVD format. Instead, 24/96 and 24/88.2 tracks in 5.1 are downconverted to 24/48 and 24/44.1 respectively. This is an automatic feature of the Bronze software, but the user is prompted when the conversion is about to take place. Fortunately, two-channel recordings at the full 24/192 resolution do not require any compression and is fully supported. Lower resolutions and sample rates are also supported as defined in the DVD-Audio specification.

Once the tracks are defined and the disc is ready for recording, the process is as simple as pushing the red record button on the toolbar. If more than one DVD recorder is installed on the machine, the user can select which drive to record to. The user has several options that can be selected including Test, Write, Verify and Eject When Done during the recording process.
