| + | ===== Tidying up speech ===== | ||
| + | If you have a piece of plain talking like an interview, voice over or speech you can improve its quality through the following effects: | ||
| + | |||
| + | First normalise your track -this adjusts the volume so the peaks are set to a certain loudness. | ||
| + | |||
| + | Then use the noise reduction function by first selecting an area of your track that should be silent and go Effect> | ||
| + | |||
| + | You can also set a noise gate. This is more aggressive than the noise reduction and will basically lower the volume (or completely remove it) on sounds below a certain level. Fiddle with the gate threshold to set the maximum volume of the background noise. The level reduction is how much quieter it will make the background noise (-100 for completely silent). The Decay sets how long it waits after the voice finishes to turn off the background noise, increase this value if your voice sounds a bit ' | ||
| + | |||
| + | Next apply a limiter, changing the "limit to" setting until you have reduced any large spikes in your audio (laughing, claps etc) | ||
| + | |||
| + | Then normalise it again as it will have changed the max volume. | ||
| + | |||
| + | Then it's a good idea to apply some compression. This is sort of a matter of taste but it tends to make voices sound more ' | ||
| + | |||
| + | Then normalise the audio again as this will have altered the volume again. | ||
| + | |||
| + | You can now export and use your audio. | ||
