DISK I/O STRATEGIES FOR HARD DISK RECORDING AND PLAYBACK
- many applications just write/read to/from the disk whenever they
want to.
- disk seek times can exceed audio latency!
- operating system handling of disk I/O can make it even worse.
- results: audible dropouts, audio not recorded.
- key problems:
- cannot read/write to disk as part of an audio processing
thread, so when can we do it?
- how do we buffer data until we read and/or write it?
