Study Notes

Pro Tools Session Folders

Pro Tools creates various subfolders based on the needs of the session, including:
- Audio Files: stores audio files created during recording, with WAV files having a .wav extension and AIFF files having a .aif extension.
- Video Files: stores video files copied during import, but only for specific workflows.
- Rendered Files: stores temporarily rendered audio files, which are dynamically managed by Pro Tools.
- Bounced Files: stores mixed-down audio files, which are the result of "bouncing" a mix.
- Clip Groups: stores exported clip groups, which are editable objects on the Pro Tools timeline.
- Session File Backups: stores backed-up session files, which can be configured in the Pro Tools preferences.

Creating a Pro Tools Session

To create a new session:
1. Launch Pro Tools and click the Create tab
2. Name the session
3. Choose the file type (BWF or AIFF)
4. Choose the sample rate and bit depth
5. Choose the I/O settings
6. Choose whether to use interleaved files
7. Select the location for the session
8. Click the Create button to create the session### Creating a Session from a Template
To create a session from a template, check the "Create from Template" box, then choose a template category and select a template from the list.
Give your new session a descriptive name, even though Pro Tools will populate the name field with the template's name.

Session Settings

Choose your session settings, including file type, sample rate, bit depth, I/O settings, and whether to use interleaved files or not.
Choose a location for your new session and click "Create" to create the session.

Sample Rate and Bit-Depth

Sample rate and bit-depth affect file size, with larger files using more CPU and consuming more hard drive space.
A higher sample rate will give more accurate higher frequencies, but may not be necessary for human hearing.
24-bit audio gives more dynamic range than 16-bit audio, but uses more file space.
Choose sample rate and bit-depth based on the project's needs, not the final output.

Audio File Formats

Pro Tools offers two audio file formats: WAV and AIFF.
WAV files are more common and compatible, and can include additional information in the file.
Both WAV and AIFF files are uncompressed PCM files, with no difference in sound quality.

Interleaved Files

Choosing interleaved files or not does not affect sound quality, hard drive usage, or CPU workload.
Interleaved files will result in fewer files in the Audio Files folder.

Pro Tools File Hierarchy

A Pro Tools session is an ecosystem of different elements, including the session folder, session file, and WaveCache file.
The session folder is automatically created and named after the session.
The session file is the nexus of the Pro Tools work, where recording, editing, mixing, and more take place.
The WaveCache file stores visual representations of audio waveforms and is automatically created by Pro Tools.
