FlutterPan
Flutter pan is a stereo pan effect baseround the pan2 abstraction that comes with Max. The following is taken from the pan2 helpfile:
"The "pan2.maxpat" abstraction pans the input signal between left and right using the buffer~ "---pan.aif". This buffer~ implements a square-root curve, which not only preserves constant power, but also results in the most accurate virtual panning angle."
In this device you can automate the movement from left to right, having control of the speed and the width of the pan.
LFO Pan
This effect takes a stereo input signal, and makes 4 interleaved copies of it, resulting in 8 output channels, each of which can be individually panned in the stereo field.
An LFO (Low Frequency Oscillator) can be applied to modulate the pan positions over time You can choose between:
- Off (1): Use this mode for static pan positions, allowing you to manually automate placement in the stereo field.
-Sine Wave (2): Applies a smooth, cyclic sine wave modulation to pan positions.
- Sawtooth Forward (3): Applies a linear rising ramp modulation.
- Sawtooth Backward (4): Applies a linear falling ramp modulation.
Please be aware that duplicating and summing audio signals can result in increased amplitude and potential clipping. There’s no automatic gain compensation included in this patch, so it's recommended to keep the output gain slightly below unity to maintain headroom and avoid distortion.
With the LFOtype selected as off you can manually set the pan position and use automation for more precices control.
RandomPanner
RandomPanner is a simple pan effect that randomizes the position of the sound in the stereo field using the mc.mixdown~ object in Max. The following is taken from the helpful of the mc.mixdown~ object:
“The default mc.mixdown~ pan mode (@pancontrolmode 0) is a circle where 0.5 is in the front middle and 0 and 1 are in the rear middle. All speakers are evenly spaced around the circle based on the number of output channels.”
You can adjust the speed, width and smoothing of the random position to create dynamically changing pan effects.
SlidingPan(D.Grosse)
While digging into MC in Max 8 when it came out, I stumbled across a great little abstraction by Darwin Grosse for randomly panning audio in the stereo field. I found it really elegant, and decided to build on it a bit.
In this version, a stereo signal is multiplied into 8 channels, which are interleaved as to preserve their stereo image to some extent: This essentially duplicates the stereo sound four times. With the ‘Random Pan’ toggle switched on, each channel begins to "slide" independently through the stereo space. The ‘PanWidth’ dial controls how far each channel can move from center, while ‘PanSpeed’ determines how quickly they drift between positions.
If you turn off ‘Random Pan’, the motion stops but the channels stay spread across the stereo field in an equidistant way, letting you manually shape the width of the overall image.
