Track Area Scrolling Conventions The vertical and horizontal scroll bars that frame the track area are standard GUI tools. Scroll thumb buttons (resembling console fader knobs) appear along the scroll bar whenever the track screen is expanded so that there are more tracks than are visible on the screen.

  • Page 18: Screen Drag (Special Scroll) Mode

    HD24/96 Technical Reference will play off screen and remain out of view. The Auto Scroll button blinking indicates that a zoom level has been selected that the auto-scroll function cannot track. Screen Drag (Special Scroll) Mode Holding the D key down when the cursor is in the track area temporarily changes the cursor into a hand icon with which to drag the screen in any direction, to the extent of the minimum or maximum axis values.

The AUTO PLAY button is located at the lower right corner of the Tools panel, next to the GUI transport buttons. Cues Cues are Locate points accessible from the GUI that you can set anywhere in the project.

  • Page 38: Recording Operations

    HD24/96 Technical Reference ANOTHER NOTE: The HDR24/96 does not resolve its word clock to incoming time code, it only uses time code to synchronize transport time. Once the HDR transport has jumped to the time code time and started running, it runs on its internal clock, while continuously monitoring the incoming time code.

  • Page 39: One Button Punch

    HD24/96 Technical Reference Press or click on a Record Ready button. This stops recording on the disarmed track, but leaves the transport running. Whenever the transport is stopped, whether with the STOP button or when time code stops, the HDR24/96 drops out of Record mode. To record again, you must press the RECORD button again.

  • Page 40: Record Safe

    HD24/96 Technical Reference Record Safe Record Safe locks out all Record Ready and Master Record switches. Any tracks that are armed become disarmed when Record Safe is activated.

    HD24/96 Technical Reference Average Meter Mode has a slower response, somewhat like an analog VU meter. The meters move more smoothly than in the Peak mode, representing the average signal level. Which to use? Most people like watching VU meters, but in the digital world, peak- responding meters are really more informative.

  • Page 45: Editing Operations

    HD24/96 Technical Reference Editing Operations Editing on the HDR24/96 is based around regions. If you’re an old hand at workstations, you’re probably already familiar with the concept of Regions. Feel free to breeze through this section and rejoin the class when we discuss tools. All editing operations are performed on screen through the GUI, so all the discussion in this section applies to GUI operations and displays only.

  • Page 51: Snap And Snap-To Functions

    HD24/96 Technical Reference Snap and Snap-to Functions When Snap is enabled, dragged objects such as regions or selection lines no longer move smoothly, with seemingly infinite resolution. Instead they snap to fixed time increments with magnetic allegiance - i.e. they move smoothly, but when a virtual (and invisible) grid line is crossed, they stick briefly so you’ll know you’re in line time-wise with the snap grid.

  • Page 52: Snap To Cues

    HD24/96 Technical Reference Sixteenth note Sixteenth note triplet Snap to Cues When Snap to Cues is enabled, the snap function will allow dragged objects and selections to 'cling' to any nearby Cue time. Region Manipulation Tools and Functions The I-Beam and Hand tools can be used to redefine and adjust the Start or End of regions. As a reminder, the start and end points of the region that you see on the screen may not necessarily be those of the original waveform file.

  • Page 53: Insert Time

    HD24/96 Technical Reference Ctrl-click when dragging combines Copy and Paste operations, leaving the region in its original place and putting a copy elsewhere in the track area. Shift-click when dragging allows you to move a region, but constrains it in time. It can move vertically (to another track or take) but can’t move horizontally.

  • Page 54: Volume Envelope

    HD24/96 Technical Reference adjustable from zero to nearly the entire region length, with three different volume curve shapes. The crossfade occurs in the area where the regions overlap, but, since regions and crossfade times can be resized at any time, it’s easy to move the point at which the crossfade occurs and adjust the crossfade length for a smooth-sounding transition.

  • Page 55: Region Editor

    HD24/96 Technical Reference Pressing the Shift key when the Node tool is active turns the pencil cursor into a double- headed vertical arrow. This tool allows you to drag the envelope line vertically and parallel to itself. In reality, it’s dragging the pair of nodes that define the line segment. If the envelope line is horizontal, Shift-clicking and dragging the line adjusts the overall playback level of the track.

    HD24/96 Technical Reference have a region with no name - i.e. left blank or erased on purpose. There’s nothing functionally wrong with that as long as you have some way of identifying the region when you need to do so (listening to it works fine). Naming is up to the recording engineer's discretion.

  • Page 57: Envelope Active

    HD24/96 Technical Reference There are three selectable fade curves, which determine the rate of change of volume over the fade time - slow, linear and fast. Your ears will tell you which one works best for the application. Adjusting fades is best done interactively – listen, adjust, listen again. You may find it convenient to set up a loop around the fade region so that you can fine tune while listening.

  • Page 58: System Setup

    HD24/96 Technical Reference Region Lock status is a toggle. Unlock a locked Region by clicking on the LOCK button in the Region Edit or uncheck Lock from the right-click pop-up menu.

    The recorder’s Ethernet card is hardware configured to operate at 100Mbps. If you wish to connect an HDR 24/96 to an existing Ethernet network that is configured for 10 Mbps transmission rates, it is necessary to use a 10/100 autosensing hub and/or a rate...

    HD24/96 Technical Reference Appendix D – Synchronization If you had only one piece of gear in your studio which recorded and played audio, life would be dandy and chances are you wouldn’t be reading this section. But because you are, we’ll assume that your life has been complicated by the need to get several pieces of equipment to record and play back in sync with each other.
  • Page 91 HD24/96 Technical Reference before you can actually see a discrepancy between their time displays. This rate of sample clock drift is actually quite normal. Understanding the simple fact of clock drift puts you way ahead of most people in understanding how synchronization works. Going back to the watch analogy, let’s suppose we were able to get two wrist watches to run at exactly the same speed.

    HD24/96 Technical Reference Sample Clocks of both units are locked to each other, it doesn’t matter which unit generates time code. The example below shows a different way of setting up two HDR24/96 units that is also correct. In this example the machine on the left generates word clock and locks to time code, and the machine on the right locks to word clock and generates time code.

  • Page 93: Jam Sync

    HD24/96 Technical Reference The answer is that time code is used to synchronize the transport position, and word clock to synchronize the sample clock rate/speed of multiple devices. Although word clock synchronization always controls the sample rate of the slave units in the same way, there are two basic ways digital audio devices handle time code synchronization.
  • Page 94 HD24/96 Technical Reference requirement for sample clock synchronization. MIDI data can be transmitted as soon as an external device tells it that it is time to go. If the time code source speeds up or slows down, the MIDI sequencer follows it. As long as the sequencer is a time code slave, there is no possibility for drift to occur.
  • Page 95 HD24/96 Technical Reference Basically, 29.97 fps time code is exactly the same as 30 fps time code except that it has been slowed down by about .1% so that it runs at the NTSC color video frame rate. The good news is that if you don’t produce anything that is going to synchronize to color NTSC video, you don’t need to use 29.97 fps time code.

    HD24/96 Technical Reference Video Synchronization Because analog systems do not have sample clocks, video is commonly used to synchronize the transport speed of multiple analog systems, most notably video tape machines and synchronizers. In a typical setup, a device called the “master house sync generator”...
  • Page 97 HD24/96 Technical Reference An example of how two HDRs can be synchronized to a VTR using video is shown below: Video / Word Clock Generator Blackburst Blackburst Blackburst Video Slave Video Slave V T R Video Slave In this setup each of the three devices is a video slave to the master video generator. This setup works well when digital audio is signals are NOT connected between the digital audio devices, but will not work when the digital audio signals are connected between the devices.

The picture below illustrates the relationship between the sample clocks of two digital audio devices locked to a common word clock signal (left) and a common video signal (right). In the case of word clock synchronization, the rising edge of each device’s sample clock is always phase-aligned such that digital audio signals are always transmitted and received within the acceptable time window.

    HD24/96 Technical Reference One can also distribute word clock to all the digital audio devices from an external source (such as the Aardsync II from Aardvark depicted above) that generates both a master video blackburst and a resolved word clock output. For smaller home setups inexpensive video blackburst generators are available for under $300.

In this scenario, the synchronizer reads time code from the multitrack and regulates the speed of the tape transport so that the time code coming off the tape is resolved to the video signal.
  • Page 101 HD24/96 Technical Reference produces a jittery sample clock that degrades the performance of any A/D and D/A converters that are slaved to it. Another important point to note is that because MTC is sent in ¼-frame packets, it is not possible to achieve positional synchronization that is as tight as LTC.

    HD24/96 Technical Reference There are times you may want to offset the position of two devices with respect to each other, but still keep them synchronized to each other. For example, you may have a tape containing audio that starts at 18:22:12:00, but you want to record this material to your HDR24/96 starting at 1:00:00:00.
  • Page 103 HD24/96 Technical Reference So what does this have to do with digital audio? Well, audio recorded on location is synchronized to the camera that is rolling at 24 fps. When the location recordings are brought in to the audio post production process, they need to be pulled-down by the film pull-down ratio to remain in sync with the picture (now in NTSC color video).

Unlike a SMPTE-striped multitrack tape where the position and rate of the time code with respect to the audio cannot change, digital systems can be set up to arbitrarily change this relationship at the touch of a button.
