Starting a track with full volume sounds amateurish. Professional producers fade in smoothly. Same with endings - a gradual fade-out feels way better than an abrupt stop. We make it happen in one click.
Want a 2-second fade? Or a dramatic 10-second fade? You control the length. DJs typically use 3-5 second fades for mixes, while podcast producers often prefer quicker 1-2 second fades.
Apply different fade times to start and end. Fade in over 3 seconds but fade out over 8 seconds? No problem. Full control over how your audio enters and exits.
