SoundCount
SoundCount is a big timesaver if you are working with commercial sounds.
SoundCount is the fast and easy way to calculate the total playtime of commercial sound in a sequence or project - for FCP users.
By leveraging the power of the FCP XML format, SoundCount allows the user to create cue sheets from a FCP sequence XML.
There are options to calculate the sound for a single track or multiple tracks. Level settings (0 levels) and audio transitons will be taken into account, though levels can be ignored optionally.
Also several sequences can be loaded to get the total time across several sequences.
The resulting tables can be simple or more detailed.
The actual version also can distinguish between foreground and background sound.
