I believe there are (or were, hopefully) similar techniques using <canvas> that exposed differences between the underlying graphics devices.
- dmazzoni 3y agoThis is similar. Audio algorithms often call OS functions and make use of CPU optimizations. One example they mentioned is the fast-fourier transform (FFT). All OS's include a version of that function but it tends to be optimized over time, and tends to behave differently on different CPUs depending on what SIMD instructions are available.
