- Traktor Control Vinyl MK2 introduced in 2011 uses advanced cryptographic techniques for higher resolution and accuracy.
- Traktor MK2 operates at a 2500 Hz carrier frequency, offering 2.5× greater resolution than Serato’s 1000 Hz.
- Traktor MK2 uses offset modulation, not amplitude modulation, making zero-crossing detection difficult.
- Pitch detection in Traktor MK2 involves filtering to produce a signal oscillating evenly around the x-axis.
- Demodulation techniques include zero-crossing detection and amplitude thresholding to extract bits.
- Traktor MK2 uses a 110-bit Linear Feedback Shift Register (LFSR), compared to Serato’s 20-bit LFSR.
- Memory requirements for Traktor MK2 are high, with a single side of timecode potentially exceeding 27 MB.
- Future improvements may involve mathematical methods to reduce memory requirements, such as structured decimation.
