PHOENIX is a TDM plug-in suite for Pro Tools HD that is designed to put analog color into the digital domain by increasing apparent loudness without increasing gain (e.g., by modeling analog tape compression). The result is that added realism that is missing in many modeled synths, EQs and digital samplers. The five different "flavors" of PHOENIX can result in a much more musical and satisfying sound.
Each one of the five different TDM plug-ins emulate different tape characteristics. Each one also incorporates a color change button allowing three choices to modify the process per plug-in. The Gold button is the position where the color is approximately flat in frequency response, with Sapphire being a bit brighter and Opal having a warmer tonality. A level control determines the amount of the PHOENIX process integrated into the audio signal, and an input trim determines "how hard you hit the tape." Because the DSP process is level dependent, reducing the input level will also cause a change in sound.
