Florian Mrugalla, a renowned name in the world of audio plugins, has released a new tool called ALLHaas. It is a free stereo widening plugin designed exclusively for Windows users. The primary function of this plugin is to help users place elements in the mix, which it achieves by using a large number of allpass filters.

ALLHaas comes equipped with several features that enhance its functionality. Each channel of the plugin has three key parameters: distance, cutoff frequency, and resonance. The distance parameter represents the number of allpass filters, while the cutoff frequency and resonance parameters determine the width of the cutoff. Users have the flexibility to adjust these parameters according to their needs.
In addition to these features, ALLHaas also allows users to switch between L/R and M/S modes. This feature further increases the versatility of the plugin and enables users to adapt it to a variety of mixing situations. For those concerned about mono compatibility, ALLHaas includes a dedicated button for checking this compatibility, making it a comprehensive tool for stereo widening.
While ALLHaas is a free plugin, it offers a level of functionality and versatility that is often found in premium offerings. Its user-friendly interface and diverse features make it a valuable addition to any audio engineer’s toolkit. As it is compatible with Windows, it is accessible to a large number of users.
For those interested in enhancing their stereo widening capabilities, ALLHaas is available for download on Florian Mrugalla’s official website. Given its features and free availability, it represents a valuable asset for both beginners and experienced audio engineers.
