You position your sound source in an extended space in front of the listener. Physically-specified micro-delays locate sources' distance and direction by manipulating realistic phase differences and attenuation. Matched convolutional reverb adds the scale and character of the environment:
- distant sources sound different from close ones
- the middle of the room sounds different from the corner
- reflective surfaces sound different from absorbent ones

A key use case is as a subtle room reverb bringing together tracks that were recorded virtually or in separate sessions as if they happened in the same space and at the same time.
Multiple instances can use the same room preset, each sound positioned at its own location on the sound stage, giving a sense of coherence and the authenticity of a live performance.
The beta program at hartleydsp.com allows you to register and download a free timelimted beta version (Windows VST3). Early beta testers can earn a free full product by submitting useful/detailed reports. I'm looking for feedback on the concept, workflow, and any issues you encounter with installation or operation with different DAWs. On the website you'll also find demos and more information.
Background: This is the first product from a new solo developer. I am a retired academic neuroscientist with a background in spatial cognition, hearing and memory. I am focussed on developing a few high quality and genuinely useful tools that go beyond those you already have.
