VirtualDub help - Dialogs: Audio volume
Permits volume adjustments to audio, to make the audio louder or softer.
| Note | VirtualDub hard clips when amplifying audio, so boosting the volume too much will result in distortion. |
| Note | It is easier to make soft audio louder than to make loud audio softer -- if the source audio was so loud that it clipped during recording, introducing distortion, reducing volume after the fact won't remove the distortion. On the other hand, amplifying soft audio also amplifies quantization noise, which is particularly bad with 8-bit source. Try not to adjust volume more than you need to; it is better to record audio at the right volume in the first place. |
