Here is a video from Avid, makers of Pro Tools, the highlights a few very convenient export tools. The first one is the ability to change the format, bit depth, and sample rate on the fly, before you actually export the mix. The second feature is also nifty for sharing sessions with others. The example in the video has several stem tracks (sub-mixes from the session such as flutes, guitars, voices, etc. If you want to share a session that includes only the stems (as opposed to every single track plus the stems), you don’t have to render the stem tracks and import them into a new session (the old way). All you have to do is select the stem tracks and you can save only the selected tracks as a new session, which will contain only those tracks. I love time-saving tools!
