MS Windows

HDS is available for any Windows version, both as a standalone application (HDS app) and as a so called VST plugin for professional use. (VST version will become available soon).

If it is intended to use HDS app with the built-in computer speakers, then it is mandatory to install Virtual Cable, which is included as a separate installer. VAC  (Virtual Cable) offers audio routing; a mandatory feature in order for the HDS driver to capture all audio streams.

If it is intended to use HDS app together with external equipment via an external sound card, VAC will not be needed. Instead, just select HDS input and output audio lines on the sound card and get going.

While HDS itself tend to be rather trivial in use, normally used with the default settings and rarely causing any problems, audio on a PC on the other hand can be a non-trivial affair. In particular, when the default Directsound audio drivers are used there is often an annoying delay included. (Called latency). To correct of this delay, it is recommended to install the freeware program Asio4All, magically cutting away any delays and granting other benefits regarding audio quality. It is very easy to install and use Asio4All. Recommended!

In particular, investigate the built in use of various sound “enhancers” on windows 7. It is higly recommended to turn off all such features in the sound control panel, see Windows 7 guidelines for that. Please report any problems encountered, even if not related to HDS. Thanks!

Finally, remember that HDS is a technology for stereo speakers. Do not use with headphones, it will not work. Do not use mono speaker, it will not work.
