Ringbuffer vs NBuffer #960

What is the difference between RingBuffer and NBuffer in terms of how they handle old data when the buffer is full? |

All buffers are working in the same way, that they can't write any data when the buffer is full. The difference is, that the Ringbuffer allocates 1 array and the NBuffer allocates n arrays: The NBuffer is just a flexible abstraction of e.g. a double buffer (when you define the number of buffers as 2)! If you want to overwrite old data, this is simple: just check if you have enough free space to write and if not, read the amount that you want to be ignored, to free it up. As an exception: the VariableSpeed related buffers however are working a bit different, but this is related to pitch shifting, which is another special topic. |
