Why should I bake a waveform into a texture?

  • Pros: You can render a waveform with almost zero cost on the CPU side. It never waste heap/GC memory.
  • Cons: You have to bake a waveform at build time. It's not very useful for interactive contents.

In other words, this technique is only useful when you're creating something not interactive, and you prefer torturing GPU rather than sacrificing the precious CPU time and memory.
