Pro Tools 101 Review Questions

me and describe five types of production tasks that Pro Tools can be used for Audio Processing: recording of audio performances and stores them as files. Works with audio that is stored electronically in digital format MIDI Production: record and edit MIDI data. Captures performance event data. Devices are involved. Notation and Scores: ways to display and work with MIDI compositions in music notation and printing capabilities. Mixing and Automation: Controls signal routing, effects processing, signal levels, panning, etc... Audio for Video Post-Production: Import QuickTime movies or Avid video files and add audio sound effects, music, Foley, and dialog. What is the frequency range of human hearing? 20Hz to 20kHz - 1kHz = 1000Hz What does the frequency of a sound wave affect in terms of how we perceive the sound? How is frequency measured? Frequency of a sound wave affects the pitch that we hear. The higher the Frequency number, the higher the pitch. Frequency is measured in either cycles per second (CPS), or Hertz (Hz). - 15000CPS = 15000Hz = 15kHz What does the amplitude of the sound wave affect? How is amplitude measured? Amplitude of the sound wave affects how loud it is. The higher the Amplitude, the louder the sound. Amplitude is measured in decibels (dB) How does the sample rate of a system relate to the frequency of audio it can capture? What is the name of the law that specifies the relationship between sample rate and audio frequency? The higher the sample rate the more accurate representation to the frequency of audio(sound). More sample rates = less chance for misrepresentation of audio clips/wrong tones. The law that specifies the relationship between sample rate and audio frequency is Nyquist Theorem or Sampling Theorem. How does the bit depth of a system relate to the dynamic range of audio it can capture? How can you estimate the dynamic range of a system? The bit depth is the binary word length of a "sample". In order to know the dynamic range of a "system", you would need to know the bit depth. You can estimate the dynamic range of a system by multiplying the bit depth by 6. An 8-bit binary word x 6 = 48dB. What are some common digital connections available on Pro Tools audio interfaces? What type of connector jack does each use? S/PDIF (Sony/Philips Digital Interface = RCA jacks(coaxial jacks) AES/EBU (Audio Engineering Society/European Broadcast Union) = XLR-type connectors. Name some audio interfaces that are compatible with standard Pro Tools software. Pro Tools | Fast Track family Pro Tools | Mbox family Pro Tools | Eleven Rack Name some audio interfaces that are compatible with Pro Tools HD software. HD OMNI HD I/O HD MADI Name some of the folders and files that Pro Tools creates as part of the session hierarchy. Where is the session file (.ptx) stored? Pro Tools Session > Pro Tools S - WaveC - Audio Files - Bounced Files - Clip Groups - Session File Backups - Video Files The session is stored inside the session folder of the same name What is the WaveC file used for? What happens if the WaveCache file gets deleted or goes missing? Stores all waveform display data for audio in the session The session may open more slowly if the WaveCache file gets deleted or goes missing Where are audio files stored in the session hierarchy? Each recording is stored separate with their audio corresponding "audio files" folder Where are Pro Tools' MIDI files normally stored? Within the Pro Tools session Which component should you turn on first when powering up a Pro Tools system? Which component should you turn on last? External hard drives that require external power should be turned on first Audio monitoring systems should be turned on last What type of processing does the Hardware Buffer Size affect? What type of processing does it not affect? Higher buffer size less load but more latency - low latency domain. Not - playback tracks and plug ins. Max buffer size lessens the load on cpu Affects monitor latency - does not affect dsp processing What kinds of commands can be found under the Pro Tools view menu? How does the View menu differ from the Window menu? File, Edit, View, Track, Clip, Event, AudioSuite, Options, Setup, Window, marketplace, Help View = Affects the display within Pro Tools windows, tracks, and clips Window = Displays various Pro Tools windows What kinds of commands can be found under the Pro Tools Options menu? How does the Options menu differ from the Setup menu? Toggle on/off Editing, Recording, Monitoring, Playback, and Display, Loop, pre/post roll, Dynamic Transport mode, scrolling options Setup = configure of various Pro Tools hardware and software parameters Which main Pro Tools window displays audio waveforms and can be used to work directly with audio, MIDI, and video files on tracks? The "edit window" displays audio waveforms Which Pro Tools window provides access to Pan controls and Volume Faders for each track? The "mix window" provid
