Red Panda has released the Bitcrusher , a guitar pedal built using the Line 6 ToneCore DSP Developer Kit (TCDDK). Here's what they have to say about it...
A bitcrusher reduces the sampling rate and resolution of a signal without any filtering, resulting in aliasing and quantization noise. When a digital signal is resampled at a lower sampling rate it creates copies of the signal (aliasing). Unlike a fuzz, these copies are not harmonically related to the original signal. Samplers and digital audio workstations use filters to remove the aliased components, but they are essential to a bitcrusher's character.
When too few bits are used to represent a signal, each sample is rounded to the nearest allowed value and no longer matches the true signal level. The rounding errors cause noise, called quantization noise, because the actual signal is approximated using a small set of values. 8-bit computer audio is a good example of quantization noise, but the Red Panda Bitcrusher can go all the way down to 1 bit.
Bit crushers are great for shredding your signal, but they can also make your ears bleed. We spent months tweaking to make a more musical bit crusher (but it can still shred).
Features

• Stereo bitcrusher
• Works with stereo or mono ToneCore® docks We highly recommend a stereo dock!
• Works with guitar, bass, and line level instruments - 1 bit setting adds significant gain to quiet guitars
• LFO modulation of sampling rate
• Sampling rate can track input signal pitch or envelope
• Envelope modulation of wet/dry amount
• Custom knob responses provide wide range along with more control in the most useful ranges
• Proprietary bit reduction algorithm incorporating a noise gate and fractional bit depths
• Developed using the Line 6 ToneCore® DSP Development Kit
• All new custom DSP code
• 15 day return
• 90 day warranty

Pricing and Availability:
The Red Panda bitcrusher is designed for use with all Line 6 ToneCore® pedals and docks. If you already have a mono or stereo ToneCore® dock, you can buy the bitcrusher module alone.

• Stereo pedal: $175 + shipping
• Module only: $85 + shipping
