Arduino programmer needed for Music-to-LED Visualizer project

Looking for an experienced Arduino programmer to write code for a Music-to-LED visualization project, preferably someone who has experience with signal processing using FFT, and/or experience programming LED arrays. Arduino will be listening to the audio signal from the connected microphone, processing it in real time and displaying some relevant animation on a single LED strip. See examples in the attachment. Hardware: - Arduino board with ATMega328p chip - Elecret Microphone with amplifier - LED strip (WS2811 or similar, up to 150 pixels) Visualization Patterns: There will be two patterns of visualization needed for now. - Pattern#1 - Almost almost identical to the animation shown in the Example_1, which is basically a frequency spectrum analyzer projected into LED strip. - Pattern#2 - Will be similar to the animation shown in the Example_2. Animation will be reacting only to a certain frequency range. Plus there will be another very simple animation added which will be reacting to another frequency range. More details to be provided. Libraries: It would be a great advantage if a programmer has previous experience with any Arduino LED or FFT libraries. There are many of them available. Please let us know the following: - Which LED / FFT library(-s) programmer has most experience with (if any)? - Which libraries are intended to be used for this assignment? - Desired compensation
