The LIN Family

LINearise Stereo and LINSurround multichannel for redithering…the missing links between distortion and definition.

LINearise & LINSurround :: Cross-platform Plugin

LINearise and LINSurround are MAAT's way of rethinking of redithering.

Your Sound, Your Way

Sharing the same user interface, MAAT’s two-channel LINearise and multichannel LINSurround are the final links between production and delivery. Offering optional word length reduction and three dither 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, LINearise and LINSurround feature VPD™, Variable Probability Density, an exclusive feature that allows you to dial in the dither spectrum anywhere between rectangular and Gaussian distribution.

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 offer a choice between rounding and truncation.

Need More?

LINearise and LINSurround have it. As you’d expect, automatic muting and variable bit depth but also a choice of rounding, truncation or no change to those least significant bits. Noise shaping and dither gain are also adjustable so, between all the choices, you can define the perfect low amplitude character for your client’s work.

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 change it to keep it distortion-free and to embed program content in the noise floor. That’s dither. Use it to make your digital audio less…“digital!”
