There are tools that allow audio files to be analysed for common problems — especially prevalent in video production — such as clicks, pops, hum and noise, and all the other common functions such as normalisation, fades and gain changes are also supported. At sample level, you can also redraw the audio data to get rid of digital spikes and other short-duration artifacts. Zoom tools allow you to home in on sections of interest, and interestingly, you can also toggle between a waveform view and an audio spectrum view.
The waveform display also animates to enable you to visualise the results of your processing. Actions and Analysis buttons show either the Actions list or the Analysis Type with relevant parameters and analysis result listings. The Analysis functions include the ability to check for clipped audio, provided the file has not subsequently been reduced in level — the audio has to hit the end stops to be recognised as clipping.
Some analysis types have parameters, such as threshold, that need to be adjusted prior to analysing the file. When Actions is active, you can add real-time effects via the Effects tab.
One feature that will make Logic users jealous is that you can also 'flatten' the results to make them permanent, without having to bounce and re-import a new file. Any actions performed on the audio, such as normalising, are listed in the Actions window with a tick box alongside each action. Unchecking the box reverses that action up until the point where you decide to flatten the file and make your edits permanent.
This is a particularly elegant feature and goes far beyond being a simple undo-redo history. For example, you can reorder actions by clicking and dragging, and you can undo an single action you did several steps ago without having to redo lots of later ones. Additionally, Actions can be temporarily bypassed rather than undone, so this feature really does make for a flexible workflow. What's more, you can save Action sequences as Apple Script droplets to facilitate drag-and-drop batch processing.
Action droplet settings may be edited directly in the Apple Script editor so it's not difficult to make small changes to a multi-stage batch process that you've set up. Soundtrack Pro also ships with a number of 'Automator Actions' that take advantage of the new Automator features in the Tiger operating system. In effect, these make it possible to automate certain audio processing tasks sample-rate conversion, audio trimming, denoising, normalising and so on without having to write your own Apple Scripts.
While the waveform editor might not have quite so much functionality as the most advanced dedicated audio editing packages, it comes pretty close and handles all the essentials such as sample-rate and stereo-to-mono conversion, fades in and out, normalising and gain change, reversing and time-stretching. It also has a fingerprint noise-reduction system that works reasonably well providing you don't give it anything hopelessly noisy to deal with.
This isn't a conventional real-time plug-in: instead, you load in a section of noise, then loop the audio while adjusting the threshold control until you get the best result. When you've tweaked to your satisfaction, you can then apply the process to the whole file or to the selected region. While not quite state-of-the-art, it's infinitely better than the denoiser in Logic. Track level and pan can be adjusted in the main page using controls in the track header section where you can also mute and solo tracks, add insert effects as plug-ins and send to a reverb buss.
Automation is available via a pop-up menu and the now familiar folder content 'swivel arrowheads' allow the automation relevant to any given track to be displayed directly below it, again not unlike the way it is handled within Logic. Three automation modes are supported — Latch, Touch and Read — and automation data may be input directly from a mouse or hardware controller, or edited graphically using envelopes and breakpoints.
Hardware control surfaces that impement the Mackie Control protocol are supported. When you come to mix a project, there's a dedicated Mixer page where each track, buss and output has a channel strip with level meter, level control, mute and solo buttons, slots for adding effects, pan controls and so on.
Each track may be given an icon selected from a list, again rather as you can in Logic, though there is a great choice of colourful icons here that would make most Logic users jealous!
A pop-up menu lets you select an output for the track or buss as well as letting you pick multiple physical output channels for the output audio channels. Conceptually, this isn't dissimilar to the Logic Track Mixer, though it looks a little simpler. Finished projects may be exported as audio files or as a Quicktime movie.
There's also a Media and Effects Manager, which comprises five tabbed areas and is designed to allow you to find and preview audio, video and effects. A Browser window lets you trawl through your hard drives and folders in the usual way, and favourite items can be stored under the Favourites tab. The Search tab lets you locate audio files filtered by criteria and you can also search for specific text or Apple Loop tagging descriptors.
Candidates may then be auditioned from within the Search Results list. The Bin tab contains media files added to the project and you can drag files directly from the Bin onto the timeline. Files not currently added to the project are dimmed, whereas off-line files appear with red text.
Using an Effects tab, you can add plug-in effects and configure effects sends for the project and also call up information on effects already instantiated on tracks, busses, outputs or audio files.
Soundtrack Pro now includes over 50 plug-in effects from the Apple range, including high-end reverb, delay, EQ and chorus plus more dramatic sound-mangling processors like Sub Bass, Bitcrusher and Auto Filter. Posted on Jun 16, PM. Page content loaded.
It should contain 14 other folders filled with different types of sound effects. Jun 17, AM. I've done a search of the internet and all the forums I can find. A lot of people were complaining about the same problem and the consensus appeared to be that it was a bug. Jun 17, AM in response to Ian R.
Brown In response to Ian R. Any idea on how to fix this problem? Jul 29, AM in response to Ian R. I am having the same problem - with one additional twist - When I setup FCP7 I put these files on an external disk as they do take up a huge amount of space.
Is there a way to point to these withing FCP X? Jul 29, AM. Nov 11, AM in response to Ian R. Admittedly I am replying to an old pos of yours. Did you ever find a solution for this? I, too, have those same two greyed out folders. Nov 11, AM. Nov 11, PM in response to dastoelk In response to dastoelk.
