This plugin is a virtual dynamic range compressor.

TDR Feedback Compressor is dedicated to sum/bus compression, its design is based on intensive studies on feed-back compressor topology. Most modern compressors analyze the input signal to control gain reduction. The feed-back compressor design however “listens” to its output. This non-intuitive approach delivers an unobtrusive and transparent compression characteristic that is able to handle complex signals with ease.

This plugin features a minimalistic audio-path and state of the art digital signal processing techniques - tuned for musical applications. Unlike the current hype on analog or vintage model compressors - this plugin is a completely unique compressor.

Features:

• Typical “Feed-Back Compression” sound and behaviour.
• 64bit floating point precision for all relevant calculations.
• Bit-transparent differential oversampling structure (only the “wet” part is oversampled).
• Internal re-sampling via high quality linear phase filters.
• Advanced stereo-linking (reduces audible cross-modulation).
• Adaptive integration time RMS detector. Optional PEAK detection.
• Freely adjustable compression knee.
• Blend between the original and compressed signal.
• Optional side-chain 6dB/Oct high-pass filter.
• Optional harmonic distortion generator.
• Optional velocity-based auto-release (dynamic adaptation of release shape and timing for transparent gain reduction).
• Delta preview mode. Allows to preview the difference between compressed and original signal.
• Latency compensated parallel bypass (i.e. processing not interrupted).
