Sound Strip

As well as images and movies the Video Sequencer can also edit audio tracks. You can add Waveform Audio format WAV, mp3 and other audio formats files from your drive, or from sound encoded within a movie, and mix them using an F-curve as a volume control.

Example of sound editing.

Trabalhando com trilhas de áudio

A Sound strip is just like any other strip in the Video Sequencer. You can select and move it, adjust its starting offset using LMB over the strip handles, and K cut it into pieces. A useful example is cutting out the «um’s» and dead voice time.

You can have as many Sound strips as you wish and the result will be the mixing of all of them. You can give each strip its own name and volume via the Sidebar region.

A sobreposição de faixas é automaticamente misturada durante o processo de renderização. Por exemplo, você pode ter o anunciante no canal 5, a música em plano de fundo no canal 6, e os efeitos de sons naturais do cotidiano no canal 7 (Esses sons também são apelidados de «Foley» em Inglês, verifique «Foley(cinema)» na enciclopédia livre Wikipedia).

Animando as propriedades das trilhas de áudio

To animate Sound strips simply hit I over any of its values. Examples of animating an audio strip are to fade in/out background music or to adjust volume levels. Layered/crossed Sound strips are added together; the lower channel does not override and cut out higher channels (unlike image and video strips). This makes Blender an audio mixer. By adding audio tracks and using the curves to adjust each tracks” sound level, you have an automated dynamic multi-track audio mixer!
