Generate sound effects by using text prompts in a few simple steps.
With Voice to sound effects (beta), you can use your voice to guide the generation of sound effects. When you combine your recorded voice, which indicates when the sound effect should occur in the timeline and how loud it should sound, along with a text prompt, Firefly refers to the energy and timing of your voice to generate sound effects that match the dynamics of your recording.
Learn to combine your recorded voice with a text prompt, syncing the energy and timing of your voice to create sound effects.
Using Voice to sound effects (beta) can be beneficial for precisely timing sound effects to match actions, ensuring they align perfectly with intended events in the timeline. This approach helps avoid the inefficiencies of working with sound clips that are either too long or too short to match the actions and events in the video or audio timeline.
Recording your voice is only used to guide the timing and energy of the generated sound effect. This feature does not generate speech or sung lyrics.
