Freedom from feedback
Instead of applying the same levels of feedback cancellation for all situations, WhistleBlock uses varying levels of suppression depending on each specific situation.
A tagging and  identification module accurately distinguishes between feedback and feedback-like tonal sounds, so phase cancellation can be applied without causing audible artifacts. The added stable gain provided by WhistleBlock is especially important for open and power fittings.
WhistleBlock has now been further enhanced byadding real-time and continuous channel-specific activation of the tagging and identification module as well as the actual feedback cancellation. This resolves the usual need for a trade-off between more stable gain and sound quality, resulting in superb sound quality while feedback is always under control.
