Here are my notes for lesson 9:
Chapter 9 Section 1:
- Playback engine selector: The playback engine is the device through which the audio from pro tools is being played back on.
- H/W Buffer Size: Hardware Buffer size is the number of audio samples that the CPU passes to and from the I/O hardware in on go.
- Host Processors: The Host Processors setting determines how many processors in your system will be allocated for native plugin processing.
- CPU Usage Limit: The CPU Usage Limit allocates resources from your CPU to host based tasks in Pro Tools.
- Host Engine: Ignore Errors during playback/record is an option that allows the host engine to ignore errors that impede recording or playback, however it does so at the cost of some audio quality.
- Delay Compensation Engine: The Delay Compensation Engine compensates for delay introduce into your pro tools system. Has 4 settings under this option.
- None - No delay compensation
- Short - introduces a delay of 1023 samples (at 48kHz) into your signal path for each channel.
- Long - Introduces a delay of 4095 samples (at 48kHz) into your signal path for each channel
- Maximum (Not available on HD systems) - introduces a delay of 16,383 samples (at 48kHz) into your signal path for each channel.
- Latency: Amount of time it takes for a digital signal to go from on place to another.
- Plug-in Streaming Buffer Size: Determines how much memory is allocated by the DAE for streaming the files associated with the samples being used in structure.
Quiz review answers:
- "Latency" is a delay in the audio signal cause by analog to digital conversion, signal processing, and computer related processes.
- The "Playback Engine" determins the device that plays back the output of Pro Tools.
- "Delay Compensation engine" introduces a predetermined amount of delay into your signal path for each channel so that all channels play back in sync.
- The "I/O Setup" tab allows for detailed routing of your inputs and outputs for Pro Tools and has configurations for your interface.
- Pro tools makes everything easily customizable and allows for improvements to your workflow by offering many choices in the "Preferences Menu"
Section 2:
- Edit Mode Buttons:
- Shuffle: Shuffle mode allows you to edit, copy, cut, and paste clips, however the movement of clips is dependent on other clips in your session.
- Slip: Slip mode allows you the freedom to place clips anywhere on your timeline.
- Spot: When moving a clip in spot mode a dialogue box appears asking for the specific place on the timeline you want your clip placed.
- Grid: Grid mode allows the user to place clips on your timeline according to a pre-determined grid value.
- Absolute Grid: Means moving a region will snap to the nearest grid mode value.
- Relative Grid: Means moving clips will always move the clip by the pre-determined grid value, relative to whatever the starting position of the clip is.
Section Review Questions:
- "Grid mode" is an edit mode that conforms clips to predetermined time values in your edit window.
- Within the edit tools, the "Trimmer" tool is a quick way to lengthen or shorten a clip
- "Relative Grid Mode" moves the clip by the user defined grid value based on the clips starting position.
- The "Grabber tool" has three variations in its drop down menu. Time, Separation, and, object.
- Inserts process "100%" of the signal and are inserted directly into your signal flow.
Section 3 Review Questions:
- The mix window in pro tools is laid out in "Channel strips" which resemble an analog console.
- The key command for switching between mix and edit window is: "Command/CTRL + +/= Key"
- The mix window in pro tools contains a powerful tracks edit area where visual representations of waveforms can be edited and manipulated: FALSE.
