Is there a filter that will let me go slower than half speed without sounding like Berry White? Same with speeding up and getting the chipmunks. Thanks in advance for recommendations. |

Yes...
Audio, use advanced filtering.
Audio, filters...
- enable Auto-connect & Auto-arrange
- Add, Input
- Add, Time stretch ("Stretches audio in time without changing pitch")
- Add, Output
- Double-click Time stretch filter, enter 2.0 for half-speed audio. |

if you go below half speed with that filter the pitch changes, want to avoid that. |

Oh, I didn't realize that - interesting. Okay, you can run multiple instances:
input->timestretch(2)->timestretch(2)->timestretch(2)->output
EDIT
You can also use Avisynth, TimeStretch: | CODE | Avisource("my video.avi")
TimeStretch(tempo=16.7) ## 16.7 = 100/6 = 1/6 normal speed
|
Or you can use Audacity, Change Tempo filter.
These two alternatives sound less "crackly" at very slow tempo than VirtualDub's timestretch.

didn't think of using time stretch multiple times, I'll dabble with avisynth as well, thanks. |
