Please add opencl to audacity because its badly needed. Currently cpu is used for previews and any other operation. Audacity can become the gimp of music editing if it incorporates opencl.

OpenCL is not a "solution", it's a "framework". For many operations the performance bottleneck is disk I/O rather than CPU, so improving processing performance may not have as much of an impact as you expect. The Audacity developers look to various technologies for improving performance (including OpenCL). Audacity now uses SSE2 for some operations, and the developers are looking to make some operations run in parallel processes so as to take advantage of multiple CPU cores when available.

Opencl is a solution and it can be considered a framework. I know there is partial opencl work available on its git, I also know opencl isn't as trivial as is writing simple C++ hence its not widely incorporated.
