Precision redithering…the missing links between distortion and definition.
The LIN family is our rethinking of redithering.
Sharing the same user interface, MAAT’s two channel and multichannel LIN family are your final link between production and delivery. Offering optional word length reduction and seven noise shaping spectra tailored to both analog and digital delivery of assets, LIN is highly adjustable to help create your own signature “sound.” In addition to TPD and weighted TPD, LINpro and LINSurround feature four newly developed fifth, eighth and ninth order psychoacoustic noise shaping choices. As with all dithering mechanisms, LINpro must be the very last plug–in instance, just prior to converting to the final, fixed–point format.
LINpro and LINSurround incorporate the latest advances in auditory and psychoacoustic research. Older, outdated dithering engines rely on decades–old approaches to the problem. We at MAAT evaluated our original LINearise engine and realized that we could “do it” even better, implementing a more accurate, mathematically superior approach plus new thinking on both the User Experience (UX) and how you want your master to sound. Whether you’re delivering a 16 bit Red Book dupe master, a 24 bit “high res” 88.2k file to today’s higher fidelity streaming services, or multichannel 48k stems for video and motion picture surround work, the LIN family will take you there with the best sounding tracks obtainable.
LINpro and LINSurround have it. As you’d expect, automatic muting and variable bit depth, 16 or 24 bits, but also a choice of 8 bit output to instantly hear how your current choice “sounds.” In addition to Triangular Probability Density Function (TPDF) and High Passed TPDF, rectangular dither is also available for educational or experimental exploration.
Rounding performs fundamental linearization, what can be thought of as very low amplitude distortion reduction, by representing all former least significant bits with one single LSB in the resulting word length–reduced version. On the other hand, truncation does not preserve any of that low amplitude information. Instead, it’s just thrown away. LINEarise is one of the only redithering products available that offers a choice between rounding and truncation.
LINpro and LINSurround bring visual certainty to the arcane art of dithering. We’ve included real world plots of each noise shape for your viewing pleasure. These are not MATLAB simulations, they are actual plots generated by LINpro’s optimized dither engine. Notice that the -100dBFS input signal, that spike at the left side of the plot, is preserved even though the word length has been reduced to 16 bits. A 16–bit word can only encode or store 96dB of dynamic range. Any information quieter than -96dBFS should be lost when reducing the word length to 16 bits. With LIN, up to the 19th bit of the input signal is preserved, embedded in the resulting 16–bit word.
Dither is a fundamental aspect of today’s DAWs. Although not usually thought of as such, re-dithering is important DSP (Digital Signal Processing). In the distant past, much of the pioneering research on dither was performed at Bell Labs. According to information theory, you should add a pinch of noise to your digital audio every time you alter it to keep it distortion–free and to preserve program content by embedding it in the noise floor. That’s dither. Use it to make your digital audio less…“digital!”
Redithering with LINpro and LINSurround: highly adjustable, easy to use and versatile. Considering LINpro but just starting out? LINone is our easy to use, lower cost entry into a world of better delivery. LINone provides the essentials, delivering precision dithering for 16 or 24 bits using LINpro’s superior, modern engine.
LINpro and LINone work with either mono or stereo tracks, while LINSurround is channel count–agnostic. With LINSurround, up to 128 channels are supported.
“Just bought the LinnPro dither stereo version because that 9th order psychoacoustic dither is one of the most transparent dithers I’ve heard in a long time. I had been using the Sonalksis Ultimate Dither plugin set for mastering and either acoustic or hybrid material (which I think can be better than what iZotope offers). But the 9th order dither with rounding for 24 bit audio at 96K (mixing down from 32 bit float) is incredibly natural sounding. I think it also beats out the old Apogee UV22 dither (which Logic no longer bundles but Steinberg Wavelab includes it). UV22 always seemed like it did something special (in a good way) to the low end, but sometimes at the expense of the midrange and high end. But (LINpro’s) psychoacoustic dither seems to just evenly affect the entire spectrum.”
