Sound Redirector
is a simple portable application to redirect Wave In to Wave Out.
Any Wave In source and any Wave Out output can be selected. The most evident scenario to use the program is to connect an analog set to line-in (e.g. old walkman). Mute the line-in playing source, and enable the line-in recording source then start the program and choose line-in for input. Then you can use equalizer, noise filter and other effects your sound cards provides on wave out but most likely not on analog line-in. From version 2.0 you can also use VST plugins.
A bonus feature is the change phase processing that helps on old cassettes where the phase is not right. You can only notice this error if you have a subwoofer for bass (the bass is very weak). Classic 2 speaker setups not affected since the left and right channels are separated fully.
The x86 version of Sound Redirector works even on Win9x.
version 1.3
1. Added adjustable buffer size so you can change latency.
2. Added option to open playback and record mixer settings from the application.
3. Slightly modified user interface.
version 2.0
The new version is completely rewritten and now uses Bass audio libraries.
This modification means that Sound Redirector 2 requires at least DirectX 8.0.
1. Added VST 2.x plugin support. Both effect and visualization plugins are supported.
2. Added volume/Balance controls.
3. Added 3 band graphic equalizer.
4. Added audio recording support.
5. Added options for selecting sample rates and 32 bit floating point sample format.
6. Added x64 binaries to support 64 bit VST plugins.
7. Settings are saved into ini file.
(This feature requires write permission to the program's own folder so do not to copy the folder into 'Program Files' if UAC is active)
The Volume and Balance controls do not influence recordings but the built-in equalizer and VST effects do by default.
The order of the effects can be changed by using the priority control in the VST effect's dialog.
Higher priority means the effect is chained earlier in the audio pipeline. The built-in equalizer has an implicit priority of 5.
So by default the equalizer processes the audio earlier than VST plugins (that have a default priority of 2).
If you set the priority of a VST effect to 0 then the effect does not influence recordings.(Recording has a virtual priority of 1.)
If for some reason you need the old Sound Redirector 1.3 that uses the pure Win32 Multimedia API (and so does not depend on Bass/DirectSound)
you can still download it: Sound Redirector 1.3
