Hi have a video file that need to put in narration in wav format, however after incorporate both narration sound and video and render them. The wav sound at 0db volume is too soft. But when i increasing the volume...i can hear loud noise at the background..how do i increase the wav volume but without an noise background. BTW.. i render the video in MOV and compression by photo JPEG.
>how do i increase the wav volume but without an noise background
With an audio processing program such as Soundbooth, Audition or the free Audacity. Beyond that: Read up on audio processing. Working at 0dB without proper normalization is inherently dangerous. Most professional mixing is done at a target level of -3dB.
