Completely talking out my ass while I wait for a fsck to finish: I guess you have to figure out why they'd want to buy it, and what kind of cost would be justified by the potential upside for them. That'd be your high bound. Then the low bound would be the minimum you need to sustain it as a business. If your low bound is above the high bound, you're in trouble... Comment...

In REAPER's case, it calculates the peak time for each block of audio.. then at a certain rate it goes and calculates the peak of all blocks to current, then replaces the meter value with that (if greater than the decaying current value)... Comment...

Question: Or rather, given a set of samples, what's the most efficient way to draw the wave in win32
Asked by Will (68.96.206.x) on January 23 2010, 11:11am
Reply on January 23 2010, 4:25pm:

REAPER uses a set of peak mipmaps, or generates it from the source if the resolution is right. In peaks mode (more than 1 audio sample/pix), it picks the next highest resolution mipmap, then finds the min/max for the range of each sample. In sample mode (1 or less audio sample/pixel), it does interpolation etc... Comment...
