The Quick Sound Field (QSF), also referred to as QuickSoundField, surrounds the performer and mic with a controlled acoustic field formed by adjustable reflective and absorptive surfaces.
In a standard QSF setup with the reflective sides facing inward, the system returns diffused early reflections back into the microphone within the Haas window, creating a sense of clarity, presence, and width at the source. Rotating the StudioTraps so the absorptive sides face inward produces a more dampened, studio-dead response, minimizing room coloration.
From these two baseline modes, the QSF can be adjusted further by changing orientation, spacing, and reflective balance, allowing engineers to shape different vocal characters acoustically, ranging from tight and controlled to open and spatial, while remaining repeatable across rooms and sessions.
For reference, the session also includes a comparison with the same vocal recorded in the open room without the Quick Sound Field, providing context for how the QSF alters clarity, presence, and spatial character at the microphone.
This session features a real-world vocal recording scenario with Halie Loren, who demonstrates the QSF in use and shares her first impressions after working with it in an actual production setting. The focus is on practical results, acoustic behavior, and repeatability, not marketing claims.
Rather than a lab-style test, this video documents how the Quick Sound Field functions in a real session and how it can be used to:
• Control early reflections • create Haas-window-based presence and width
• Achieve a dampened studio sound when needed
• Shape vocal tone acoustically at the source
• Maintain consistency across different recording spaces
What’s covered in this video:
• How the Quick Sound Field (QSF / QuickSoundField) works in a vocal setup
• Reflective-in vs absorptive-in QSF configurations
• Using diffused early reflections to enhance presence and width
• Open-room vs QSF vocal comparison
• Shaping vocal tone acoustically at the microphone
• Near-field acoustic control using StudioTraps
• Real-artist evaluation and first impressions
• Practical use in a production environment
