ATF2™ Upsampling allows digital audio signals from virtually any audio source to be upsampled, resynchronised and retimed for extraordinary levels of detail. In effect, upsampling the digital data stream (up to 384kHz) allows existing “standard” CDs to have the enhanced audio clarity, richness and dynamic range that would normally be associated with SACD or DVD-A disks “upgrading” the investment you have already made in your CDs. You’ll be astonished once you hear what you have been missing!

Three proprietary technologies are included in ATF2 effectively reduce noise artefacts caused by imperfect digital systems and allow the digital signal to closer represent the true analogue sound of the studio mastered audio data. Furthermore, by leveraging powerful DSP architectures, ATF2™ allows discerning music lovers to benefit from truly sublime high-end performance for a much lower financial outlay than ever before.


Jitter Suppression allows any incoming audio stream to be resynchronised and retimed to a local very high quality clock. By using a stable -reference oscillator , the negative effects of inter-component jitter can be dramatically reduced. When converting the digital audio to an analogue signal through high performance D/A converters, this reduction in jitter has enormous benefits in the level of detail and clarity in the reconstructed analogue sound. 
Combining this process with a time domain model using an advanced cubic interpolation algorithm, our unique ATF2 systems upsamples all incoming audio to 24 bits at 384kHz whilst applying noise shaped dither and is able to actually increase the linearity of response of the D/A converters. 
The end result is tighter, more focused bass, increased stereo imaging, focus and separation for all musical instruments and voices.

ATF2™ Upsampling also features a selectable digital filter with three settings to suit listener preferences and their particular system set-up: 

• The Steep roll-off filter exhibits strong attenuation of aliasing images outside the pass band (i.e. above 22.05kHz) at the expense of a little pre and post-ringing in the time domain. 

• The Linear phase filter uniquely features ‘constant group delay’ which delays all audio signals at all frequencies by the same amount meaning all audio is fully time-coherent at the output.

• Minimum phase meanwhile does not feature constant group delay but rather the co-efficients have been optimised without feed-forward so that the impulse response exhibits no pre-ringing in the time domain.
