Join David Franz for an in-depth discussion in this video Expanded file format support, part of Pro Tools 10 New Features.
Pro Tools 10 has a new session file format, .ptx files. You can see one right here. And as you can see, the icon looks exactly the same, but the file is different from the previous .ptf and .pts session files, and it's not backwards compatible with previous versions of Pro Tools, thus these .ptx files cannot be opened in previous versions of Pro Tools. To share a Pro Tools 10 session with somebody who's using a lower version, you'll need to use the File > Save Session Copy As command and save it as a lower session file format.
Let's create a new Pro Tools session. In the New Session dialog box you'll see that we actually have some new options. We've got 32-bit floating as a potential bit depth now. This is an increase over the previous 16-bit and 24-bit limitations. As you can imagine, these files will take up a third more disk space but increase the dynamic range and thus help avoid clipping. The higher bit depth also reduces rounding errors when doing bitrate conversions, like when bouncing down to a 16 bit 44.1 kilohertz stereo track to burn to a CD.
In the New Session dialog we can choose between the bit depths by toggling the value using Command+B on the Mac or Ctrl+B in Windows. We also see down here that we can use interleaved files. Previous versions of Pro Tools only allowed mono files, but Pro Tools 10 now supports interleaved files for stereo and multi-channel files. Let's go into the session and take a look at the session setup.
In the Session Setup dialog we can actually change the bit depth if we want to, as well as check or uncheck the Interleaved checkbox and also change the audio format if we want. And because we can change the audio format, that actually means that Pro Tools 10 now supports mixed audio file formats such as WAV and AIFF in the same session. Pro Tools 10 also supports RF64 audio files and WAV extensible file format. In the latter file format surround data, such as speaker position, is actually stored in the audio file header.
In considering that, if you're working in surround, it's recommended to use WAV versus AIFF files. So now you know all about the major upgrades in the file format support in Pro Tools 10.
