Comment: GPU is not that useful for audio (Score 1) 157
There are many reasons that make GPU not as useful for audio.
The second is that most audio processing usually relies on complex directed graphs consisting on nodes that each process a different task, and that kind of interaction is too complex for the simpler, massively parallel GPU architecture.
It would be fanastic for us that work in the audio industry to have some sort of DSP acceleration coprocessors for audio, but there's not enough demand to make that affordable so we can only wait for GPUs to become more flexible and realtime friendly, or CPUs to become more parallel.
