 This repo contains completely functional Opus implementations in portable C# and Java. They are based on libopus master 1.1.2 configured with FIXED_POINT and with an extra switch to enable/disable the floating-point analysis functions. Both the encoder and decoder paths have been thoroughly tested to be bit-exact with their equivalent C functions in all common use cases. I have also included a port of the libspeexdsp resampler for general use.
 
-Performance-wise, the current build runs about 40-50% as fast as its equivalent libopus build, mostly due to the lack of stack arrays and vectorized intrinsics in managed languages. I do not believe performance will get much better than this; if you need blazing-fast performance then I encourage you to try the P/Opus or JNI library. The API surface is finalized and existing code should not change, but I may add helper classes in the future.
+Performance-wise, the current build runs about 40-50% as fast as its equivalent libopus build, mostly because of managed array overhead and the vector instructions not porting over. I do not believe performance will get much better than this without a complete rewrite; if you need blazing-fast performance then I encourage you to try the P/Opus or JNI library. The API surface is finalized and existing code should not change, but I may add helper classes in the future.
 
 No other ports beyond C# / Java are planned at this time, but pull requests are welcome from any contributors.
