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). 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. 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.
In 1994, Pro Tools 2.5 implemented Digidesign's newly developed time-division multiplexing technology, which allowed routing of multiple digital audio streams between DSP cards. With TDM, up to four NuBus cards could be linked, obtaining a 16-track system, while multiple DSP-based plug-ins could be run simultaneously and in real-time. The wider bandwidth required to run the larger number of tracks was achieved with a SCSI expansion card developed by Grey Matter Response, called System Accelerator.
While consolidating its presence in professional studios, Digidesign began to target the mid-range consumer market in 1999 by introducing the Digi001 bundle, consisting of a rack-mount audio interface with eight inputs and outputs with 24-bit, 44.1/48 kHz capability and MIDI connections. The package was distributed with Pro Tools LE, a specific version of the software without DSP support, limited to 24 mixing tracks.
When Apple changed the expansion slot architecture of the Mac G5 to PCI Express, Digidesign launched a line of PCIe DSP cards that both adopted the new card slot format and slightly changed the combination of chips. HD Process cards were replaced with HD Accel, each mounting nine Motorola 56321 chips running at 200 MHz and each providing twice the power than an HD Process card; track count for systems mounting an HD Accel was extended to 192/96/36 tracks at 48/96/192 kHz sample rates. The use of PCI Express connection reduced round-trip delay time, while DSP audio processing allowed the use of smaller hardware buffer sizes during recording, assuring stable performance with extremely low latency.
Pro Tools LE shared the same interface of Pro Tools HD but had a smaller track count (24 tracks with Pro Tools 5, extended to 32 tracks with Pro Tools 6 and 48 tracks with Pro Tools 8) and supported a maximum sample rate of 96 kHz (depending on the interface used). Some advanced software features, such as Automatic Delay Compensation, surround mixing, multi-track Beat Detective, OMF/AAF support, and SMPTE Timecode, were omitted. Some of them, as well as support for 48 tracks/96 voices (extended to 64 tracks/128 voices with Pro Tools 8) and additional plug-ins, were made available through an expansion package called \"Music Production Toolkit\". The \"Complete Production Toolkit\", introduced with Pro Tools 8, added support for surround mixing and 128 tracks (while the system was still limited to 128 voices). 153554b96e
