SpinTracer lets you manipulate sound in real time, moving sound in three-dimensional space with mouse movements. The built-in creative motion engine provides a dynamic layer for creating mesmerizing geometric patterns or random, swarm-like textures.
v1.5.0
New Features and Enhancements:
- Adaptive Background Grid: A new scene grid helps you visualize the spatial scale of your patch, including scene size, dimension changes, and the current zoom level.
- Improved Sphere Height Visualization: Sphere heights are now displayed more clearly, allowing you to better understand the vertical position of each sphere in the scene.
- Improved Control Layout: The Max Speed and Strength buttons are now located directly above the canvas, making them easier to access while creating or tweaking a patch.
- Dual-Row Parameter Layout: The Parameters section is now split into two clearer rows. The first row contains motion-related controls, while the second contains the Doppler DSP parameters, the output section, and the dry and wet controls.
- Input Spread: A new Input Spread control has been added that provides small delay offsets for individual input channels or spheres. This helps eliminate signal correlation and create a wider, more diffuse spatial texture.
- New Multi-Sphere Tremolo Module: A new tremolo module has been added, allowing rhythmic volume modulation based on spatial movement.
- Distance-dependent Tremolo Range: The Range knob determines the area over which tremolo modulation occurs based on distance. The extreme range represents the minimum value, and the listener position represents the maximum.
- Trajectory Mode and Orb Mode: In Trajectory mode, the tremolo speed depends on the distance between the trajectory object and the listener. The closer the trajectory is to the listener, the faster the tremolo becomes. In Orb mode, the tremolo speed is adjusted individually for each orb based on its distance from the listener.
- Per-object Frequency Offset in Trace Mode: In Trace Mode, all objects can either have the same tremolo frequency, or use slightly offset frequencies for each object, resulting in a wider and more dynamic modulation effect.
- Tremolo Curve Control: The Curve parameter changes the relationship between the distance to the target and the tremolo frequency, allowing for a linear, exponential, or inverse relationship.
- Dry/Wet Effect Depth vs. Target Distance: The depth of the tremolo, or the degree of “wetness” of the effect, can also be adjusted based on the distance to the target, allowing for a stronger or weaker effect depending on the target’s position.
- Dry/Wet Output X-Over Mode: An additional X-Over mode has been added to the Dry/Wet module and the Output module. Everything below the selected cutoff frequency is processed dry, and everything above is processed wet.
