In 2022, Avid switched Pro Tools from a perpetual license to a subscription model. The software and the audio engine were adapted to 64-bit architecture from version 11. Current HDX hardware systems, HD Native and native systems use 32-bit floating-point resolution for plug-ins and 64-bit floating-point summing. The Pro Tools TDM mix engine, supported until 2011 with version 10, employed 24-bit fixed-point arithmetic for plug-in processing and 48-bit for mixing. It features time code, tempo maps, elastic audio, and automation supports mixing in surround sound, Dolby Atmos and VR sound using Ambisonics. Pro Tools has incorporated video editing capabilities, so users can import and manipulate high-definition video file formats such as XDCAM, MJPG-A, PhotoJPG, DV25, QuickTime, and more. The legacy SDII format was dropped with Pro Tools 10, although SDII conversion is still possible on macOS. It imports and exports MOV video files and ADM BWF files (audio files with Dolby Atmos metadata) it also imports MXF, ACID and REX files and the lossy formats MP3, AAC, M4A, and audio from video files ( MOV, MP4, M4V). Pro Tools supports mixed bit depths and audio formats in a session: BWF/ WAV (including WAVE Extensible, RF64 and BW64) and AIFF. 16-bit, 24-bit, and 32-bit float audio bit depths at sample rates up to 192 kHz are supported. Audio effects, virtual instruments, and hardware emulators-such as microphone preamps or guitar amplifiers-can be added, adjusted, and processed in real-time in a virtual mixer. Like all digital audio workstation software, Pro Tools can perform the functions of a multitrack tape recorder and a mixing console along with additional features that can only be performed in the digital domain, such as non-linear and non-destructive editing (most of audio handling is done without overwriting the source files), track compositing with multiple playlists, time compression and expansion, pitch shifting, and faster-than-real-time mixdown.Īudio, MIDI, and video tracks are graphically represented on a timeline. The DSP is used to provide additional processing power to the host computer for processing real-time effects, such as reverb, equalization, and compression and to obtain lower latency audio performance. Pro Tools operates both as standalone software and in conjunction with a range of external analog-to-digital converters and PCIe cards with on-board digital signal processors (DSP). It is used for music creation and production, sound for picture ( sound design, audio post-production and mixing) and, more generally, sound recording, editing, and mastering processes. Pro Tools is a digital audio workstation (DAW) developed and released by Avid Technology (formerly Digidesign) for Microsoft Windows and macOS. Master Fader tracks control the overall level of the Audio tracks that are routed to the session's main output paths or busses.Chinese (Traditional and Simplified), English, French, German, Japanese, Korean, Spanish A Master Fader track is a single fader used to control hardware output levels and bus paths. VCA Master tracks are associated with a Mix group, and the tracks in the Mix group can then be controlled by the VCA Master. Auxiliary Input tracks can be used as an effects return, a destination for a submix, an input to monitor or process live audio, or a control point for any other audio routing task. Only one Video track can be active, or online, at any time. Video tracks let you add or import video to the Timeline. Instrument tracks combine the functions of MIDI tracks and Auxiliary Inputs into a single track type, making them ideal for composing with virtual instruments, sound modules, and other MIDI devices. MIDI tracks store MIDI note and controller data. Audio tracks allow you to import/record and edit an audio signal as a waveform.
