I was wondering if anybody here had any advice, in terms of general strategies, data structures, etc., about the best approach to drawing audio buffers in terms of performance (fast draw, redraw), in terms of accuracy (i.e. no aliasing), and in terms of zooming (can zoom in/out quickly). This is implemented in 99% of audio applications out there, and was wondering how people do it so fast. My approaches have generally been somewhat satisfactory, but they’ve been much slower than commercial apps.
Any advice would be greatly appreciated.
