Our unique ATF2 (Adaptive Time Filtering) upsampling technology, developed in conjunction with Anagram Technologies, Switzerland.
All incoming audio data such as a CD 16-bit 44.1kHz signal is upsampled to 24-bit 384kHz using a high-end 32-bit Analog Devices DSP (Digital Signal Processor). "Polynomial Curve Fitting Interpolation" provides a much more accurate upsampled audio soundwave than traditional upsampling processes. And a unique timing system buffers audio data to almost eradicate digital jitter. Vital – as jitter, common in digital audio devices, loses vital detail, often leaving digital audio sounding flat and lifeless.
On products that have ATF, every digital input, no matter where it comes from, wired or wireless, goes through the upsampling and jitter reduction process. From low-quality MP3 and internet radio to high res WAV or FLAC files, everything is treated the same so everything will sound detailed and full.
Please note: Upsampling only occurs when using analogue outputs as the process is implemented within the digital to analogue conversion process.
