HOFA-Plugins has announced IQ-Analyser Standalone for Win & Mac.
IQ-Analyser Standalone has the same features as the plugin but can be run without a DAW. Furthermore, curves can be viewed from a different machine using the IQ-Analyser NetAux plugin so it can be run on a dedicated machine. Of course it is also possible to monitor the audio input and even watch the audio currently played by media players (via Windows Audio on Windows and Soundflower on OS X).
Price: 99,90 € - IQ-Analyser (Standalone) will be released in September. It is also included in the Super-Bundle and IQ-Bundle. So if you purchase a bundle now, you'll also get IQ-Analyser for free.
