This is an app that greatly helps in most editing workflows. It is based on award winning Woowave Sync Engine which analyzes the sound of your clips and matches them perfectly. This version is extremely simple to use, so it can be used by professional and amateur editors as well. Simply select video file and separately recorded audio track(HQ). Click synchronize and the app automatically creates a new identical clip with HQ Audio. If you often record your sound separately, which is probably the right way to do it anyway, you will be using this app day after day. Audio synchronization is a complex process and our algorithm was developed from scratch since 2011.
