Had a chance over the weekend to update the free Riviera plugin with an improved GUI, new stereo functions, and maintenance fixes. Enjoy! Features for v. 1.3.0: New GUI! Added gain, stereo mid-side width, and left/right phase offset controls Smoother transition for mix knob Flush buffers/retriggers when reset within patterns/tracks Fixed possible crash in FLStudio when notify… Read More Riviera Plugin Updated to v. 1.3.0a
Here’s a quick video about the controls in the Riviera plugin (turn on closed-captions for descriptions). The dry clip is a collection of transients typically used to stress-test reverb effects. Below is a cross-post of the readme contained within the plugin with some further elaborations. Controls: -Fine-grain adjustments of knob are possible with the mouse wheel +… Read More Riviera: Basic controls tutorial
Recall from the introductory post, the taxi-cab distance metric on the integer lattice map relates the max-order of image-sources to the lattice volume or the total number of image-sources contained within a radius “ball”. This quantity is useful for determining the total costs of processing individual image-sources in cases where can be known or estimated beforehand… Read More Geometric Audio 4: Taxi-Cab Distance Bounds on Integer Lattice Maps
Recall in the previous post our derivation of the Gauss circle recurrence relation generalized to arbitrary dimensions, scaling, offset, and weights: where the cost of computing for for max-distance requires flops. In practice, the summation should be transposed so that is incremented within the inner loop as to take advantage of vectorization/SIMD memory access patterns. A second approach for… Read More Geometric Audio 3: Gauss Circle Problem for Integer Sized Room Models (part 2)
In the previous post on image-sources for room modeling, we made the observations that There exist a unique path from each image-source coordinate that can be back-traced to a receiver The distance and direction between image-source coordinate and listener are equal sum total of the back-traced ray lengths and the final leg of the back-traced… Read More Geometric Audio 2: Gauss Circle Problem for Integer Sized Room Models
A common audio technique for adding depth to a mix is to throw in echos or early reflections following the direct sound-source arrival to a listener. To model such reflections, many reverberation algorithms treat a sound-source and listener as a point emitter and receiver within an imaginary room or box. The reasoning follows that such a configuration… Read More Geometric Audio 1: Image-Source Room Models
Riviera is a hybrid algorithmic-convolution reverb plugin for modeling specular acoustic reflections in N-dimensional orthotopes. e.g. string, plate, room, tesseract, and up (vooms or volume+room for short). Normally, direct computation in these spaces is expensive but some clever maths [see tutorial (parts 1, 2, 3, 4)] reduced the asymptotic costs to the point of practical use (e.g. a… Read More Riviera: Hyper-Room Reverb
