Pro Tools 101_ An Introduction to Pro Tools 11 ( PDFDrive )

At its core, Pro Tools is a multi-track software-based digital recording and
editing system. It uses the power of the personal computer to combine harddisk
audio recording, graphical audio editing, MIDI sequencing, digital
signal processing (DSP), and mixing into an integrated system. With the
ability to incorporate QuickTime and Avid video files, Pro Tools has also
established itself as an industry choice for post-production video editing and
mixing to picture.
Audio
Pro Tools works with audio that is stored electronically in digital format.
The software records audio and stores it as files on your hard drive. Like a
digital camera that stores a photograph as a collection of discrete pixels, Pro
Tools stores recorded audio as a collection of discrete samples. Pro Tools
11 supports audio formats with resolutions up to 32-bit floating point and
sample rates up to 192 kHz.
Just as you can use an image editor to modify, enhance, and otherwise alter
your digital photographs in creative ways, so too can you use Pro Tools to
take your digital audio in new directions. Working in the digital realm makes
it easy to copy, paste, move, delete, modify, and otherwise manipulate your
recordings. Pro Tools lets you trim waveforms, reprocess sections of audio,
correct a compromised performance, replace drum sounds, rearrange song
sections, and more. With Elastic Audio, you have the power to manipulate
the playback speed of your audio clips, allowing you to freely experiment
with tempo. You can even quantize audio for quick rhythmic fixes or creative
exploration.
MIDI
Using built-in sequencing technology, Pro Tools also enables you to record
and edit MIDI data in the same work environment as your audio recordings.
MIDI recordings differ from their digital counterparts in that they capture
performance event data rather than sound samples. You can record MIDI
signals from a keyboard or other device through a MIDI or USB interface and
then edit the data using Pro Tools’ intuitive graphical display. The Pro Tools
MIDI Editor windows provide a platform for detailed MIDI editing on one
track or on multiple superimposed tracks.
