In unbounded mode, the read and write pointers are free to move independently of one another. This is useful where the input and output streams are progressing at the same rate on average, and we want to keep the latency stable in the event than an underrun or overrun occurs. If an underrun occurs (i.e., there is not enough data in the buffer to satisfy a read request), the missing values with be filled with zeros. When the writer catches up, the same number of values will be skipped from the input. If an overrun occurs (i.e., there is not enough free space in the buffer to satisfy a write request), excess values will be discarded. When the reader catches up, the same number of values will be zeroed in the output. Unbounded mode is currently unused since our audio input and output streams are not synchronised. This will be implemented in a later commit. Also reimplemented as a lock-free queue which is safer for use in audio device callbacks. |
