Actually 44.1kHz is unhelpful for that... a lot of infrastructure exists that expects things to work on 10 and 20ms intervals (and multiples there-of), e.g. the normal windows audio apis work in 10ms chunks.
10ms of 44.1kHz is 441 samples, which is odd and thus a not really fantastic size for easily implemented factorizations.
Of course, if you can pick your own analysis interval you can pick some nice power of two or other very smooth number. But thats true regardless of the sampling rate.
- ar7hur 12y agoAlmost all ASR engines use 25ms windows, not 10ms (they typically overlap and are processed every 10ms).
- dbecker 12y ago25ms of 44.1kHz isn't even an integer. So the original argument is even less compelling with 25ms windows than it was with 10ms windows.
