Frequency counter / Tuner / Square sub oscillator
The Audiothingies CED is a tuner (based on a frequency counter) with great accuracy (less than 1 cent) on the whole audio range.
12 LEDs indicate both detected note and pitch accuracy.
2 different display modes available.
Additionally, CED is capable of generating a square waveform, one or 2 octaves below the input signal.
Mods: the sub output can be changed to a thru output via a jumper on the PCB.
Notes: as this tuner is based on a frequency counter, it is not capable of detecting the pitch of complex waveforms (like an ultrasaw for example).
No info about availability.
