User manual SERATO PITCH N TIME PRO 2.4

[. . . ] You can even warp the timing of your samples just by placing markers and moving them around. The tempo and pitch panels can be mixed and matched to suit your application, and with a sufficiently powerful processor previewing may be done in real time. Why is Pitch 'n Time Pro an AudioSuite Plug-In? At the time of writing the Digidesign Audio Engine (DAE) supports four plug-in architectures: TDM, AudioSuite, Real-Time AudioSuite (RTAS) & HTDM. TDM, RTAS & HTDM are real-time architectures using DSP and/or host-based processing, while AudioSuite is file-based. The three real-time architectures provide the digital equivalent of "black boxes". [. . . ] Most handles are white, but the currently selected handle is shown in orange. The (input) time, BPM and percentage change of the selected handle is shown in the three fields below the graph. To create a new handle, click anywhere on the line where there isn't already a handle. To delete a handle option-click it, drag it outside the graph, or move it on top of one of the handles to either side. The line always shows how the tempo will vary smoothly between the handles you have set. By pressing the Update Waveform button (at the bottom of the plug-in) you can have Pitch 'n Time Pro display a waveform overview as a visual aid behind the automation graph. Tempo automation can be as simple as a ramp from 120 to 130 bpm or as complex as you wish. New markers can be created by clicking anywhere except on an existing one. Clicking Reset will remove all markers. 11 The Interface Length Panel No matter which time-stretching mode you are in, the length panel is always visible. It shows the start, end and length of your selection both before and after processing. You can change the output values at any time by typing into the appropriate field. When you do, the current time stretch panel is altered to match. Length / Position units Select from the pop-up menu at the top of the length panel between the following display options: Samples are the smallest units of audio that Digital Audio Workstations work with. The largest value allowed in these fields is 231-1 = 2, 147, 483, 647 samples, or approximately 13½ hours of audio at a sample rate of 44, 100 samples per second. Hours:Mins:Secs display lengths in hours, minutes and seconds, in the format HH:MM:SS. Hours and minutes will not be displayed if the length is less than one hour or one minute respectively. The default units are seconds when entering values, but colons can be used to quickly enter larger values. For instance, typing "1:" enters 1 minute, and typing "2::" enters 2 hours. Feet+Frames refers to lengths of film in feet and frames, where 1 foot = 16 frames, and there are 24 frames in 1 second of audio. This relationship is independent of the SMPTE frame rate for the session. Capture This panel also features the Capture button, which can be used to easily match sample lengths. When pressed, the capture button memorizes the length of the current selection. As soon as a second region is selected, the current time-stretch panel is automatically adjusted to create the output length that was memorized. (See the Production Examples section for further explanation). 12 The Interface Fixed Pitch-shift This pitch-shift panel works similarly to the fixed time-stretch panel, applying a simple, single pitch shift factor, displayed beneath the slider in both semitones & cents and percentage frequency change. [. . . ] When create individual files is used with playlist selected as the source, Pitch 'n Time Pro re-spots the new regions to new locations to match the selected time stretch. Multi-channel mode enforces phase coherency between all the selected tracks, up to the AudioSuite limit of 48 channels. Use this feature only when absolutely necessary, as enforcing phase coherency unnecessarily can be detrimental to the sound quality. 21 Pro Tools Plug-In Controls Pro Tools allows you to save your favourite plug-in settings for later retrieval. This button contains both a menu for saving your favorite settings, and a pop-up of any you have saved previously. At any time when you would like the current settings remembered, pull down the menu and choose Save Settings As. . . [. . . ]
