When editing an individual audio file, some edits, including normalizing or amplifying levels, applying effects, and applying noise, pop, and click reduction, are applied as nondestructive actions. Actions can be reordered, turned on or off, and removed at any time using the Actions tab.

The Actions tab lists the actions applied to “Traffic City,” the file that’s open in the File Editor.

This chapter is divided into two sections. The first section explains the different ways that Soundtrack Pro processes audio files associated with multitrack projects and single audio files that are not associated with multitrack projects. The second section explains how to perform specific edits and apply effects to audio files in both the File Editor tab and in File Editor project view.

How Soundtrack Pro Processes Audio Files

Soundtrack Pro can process a variety of audio file types, including AIFF and WAV files. To allow you to nondestructively edit a file using Soundtrack Pro actions, Soundtrack Pro will often automatically save a copy of your file as an audio project (.stap) file. This lets you immediately start nondestructively editing your file.

Any changes you make to a file’s frequency spectrum or waveform, any sample edits, audio stretching, or processing effects you add to a file are applied as actions. After adding actions to a file, you can change the order in which they are applied, turn them on or off, or remove them in the Actions tab.

Actions are useful because they are nondestructive, and you can easily preview, reorder, and remove them in the Actions tab.

Where to Edit Audio Files

You can work with an individual audio file in two locations in Soundtrack Pro. You edit files that are part of a multitrack project in the File Editor tab. You edit files that are not connected to a multitrack project in the File Editor project view.

The Apple II is a defining product in the history of personal computing, first introduced in 1977 by Apple Computer, Inc. Designed by Steve Wozniak, the Apple II was one of the first highly successful mass-produced microcomputer products and played a significant role in bringing personal computers into homes and schools.

One of the Apple II's standout features was its color graphics capability. It was one of the first personal computers to provide color output, thanks to its built-in video interface. The initial model supported a resolution of 280x192 pixels with a palette of 6 colors, which allowed for vibrant visuals that set it apart from contemporaries like the monochrome Altair 8800.

The Apple II was notable for its open architecture. This design allowed users to expand the computer's capabilities easily through a series of expansion slots. Users could add floppy disk drives, additional memory, and various peripheral devices, making the system highly adaptable to individual needs. This encouraged a thriving ecosystem of third-party hardware and software, which contributed to its popularity.

Another significant feature was its use of the 6502 microprocessor. This 8-bit CPU was not only affordable but also powerful for its time, allowing the Apple II to run various applications efficiently. Along with a built-in keyboard and an innovative plastic case that housed its components, the design was user-friendly and appealing.

The Apple II also introduced the concept of “bootable software” through the use of floppy disks. The disk operating system (DOS) allowed users to store and run multiple programs without having to reload software manually, providing a level of convenience that had not been widely available before. Key software like VisiCalc, the first spreadsheet program, helped boost sales, showcasing the Apple II's utility in business and education environments.

The computer was also well-known for its early adoption of BASIC programming language. Apple provided an operating system that supported Applesoft BASIC, which enabled users, including students, to write their programs, further fostering a community of developers.

In summary, the Apple II's color graphics, open architecture, powerful 6502 processor, innovative use of floppy disks, and support for BASIC programming made it a revolutionary product in its time. Its legacy laid the groundwork for future personal computers and established Apple as a leader in the burgeoning tech industry. The Apple II remains an iconic symbol of the early personal computing era, reflecting a generation's transition into a digitally connected world.
