New Soundbooth Feature: Match Volume
Matching volume levels across several audio files used to be a challenging and time-consuming task. With the new Soundbooth Match Volume feature, you can now drag your files over to the Match Volume area and automatically adjust the volume levels with just one click. You have the flexibility of choosing to match your files to a specified dB volume or to match them all to the level of one of the selected files. It turns out the human ear hears different frequencies at different levels, so just because two files have the same technical volume levels doesn’t mean they’ll sound the same. But don’t worry, with one check box you can have Soundbooth adjust for this ‘perceived’ loudness.
