SpecWeb is a command line (windows console) version of the SPEC stereo to surround tool from www.surroundbyus.com. It is designed to be faster and easier to use than the full “Spec” version, and does not require Plogue Bidule.
SpecWeb also has an html5 “web” user interface, which works with chrome, Firefox, iOS, android, and windows 10 edge browsers. You can control SpecWeb from a browser on the same computer or on any computer or supported device on your local network. For instance, you could sit in your home theatre listening position and control SpecWeb with an iPad.
It’s a great way to get started in making your own up mixes as all you have to do is drag and drop a lossless stereo file onto the SpecWeb icon and you get a 5.1 multichannel file in seconds.
While not all of the “knobs” from the full “Spec” version have been included, the most important ones are here and you can adjust them while you listen to the song, just as you can in the full version, then “record” the results.
This two-channel waveform editing software is capable of converting and editing high-resolution DSD and PCM files with support for up to 11.2MHz DSD and 384kHz PCM formats.
