• Track. A container for anything you record, or import. Can be audio, midi, video and other types of media, each acting normally independently from each other. This allows you to record first a guitar, then a voice and so on without affecting what you have already recorded. Programs that have this capability are called Multi-Track Recording. You may record and playback an arbitrary amount of them, limited only by your computer's processing power.
• Item: A rather flexible container for media content that a track holds. There are many ways of manipulating them and they are the main staple for editing your audio, midi ETC. They cannot exist if no tracks are present.
• take: a version, or pass, of a recording. They belong strictly to items. Their function is to help you when you want to record the same material several times, such as a solo, and then decide which one out of all the recordings you have made you prefer.
• timeline: Its name is pretty self explanatory, but just in case, the timeline represents the elapsed time of your project. It runs across the top of the REAPER window. It measures the length of your project and helps you identify the position of the various media items.
• zoom: There are two types. Vertical and horizontal. Vertical zoom adjusts the visibility of tracks and other elements, thus its not of greater concern if you have no sight. However, horizontal zoom will affect visibility for the graphical representation of audio and also will affect commands for navigating and moving things around, deserving a special mention here. The more something is zoomed in, the greater detail it displays and contains.
• Audio Jogging or Scrubbing: These are techniques originated in the days when all recording was done with magnetic tape. They help you to move within a project, or track, or group of tracks, to audition or locate a very specific, particular section. They are dependent on the horizontal zoom level. The more zoom in you have, the slower the movement will be. The more zoom out you have, the faster you will be able to scrub.
• pre-roll: This can be used so that when you start recording, or playback, the metronome will play for the specified number of measures before recording or playback actually begins.
