Another polish application idea for FV-1, this time as DSP module for low cost Behringer DJ mixer: https://www.youtube.com/watch?v=gkLiZPVPbFM
There is a link to polish forum thread with much more informations and schematics.

Hey, look what I just found

Nice stuff. There is a link to polish forum thread in the video description.

Reading in program code takes ~18ms at 32767Hz crystal. I think you should wait at least 20ms.
But your problem looks like bad PCB design.

Okay, but what is "Width gain"?

What are poles and zeros? How to understand that?

Thank you for this link, I'll try.

No, I have mono input (without stereo panorama, of course) and I want to make output sound like stereo.

Ok. I have a problem with oscillations (?) of FV1. I've recorded it, could you listen? https://files.fm/f/qxuajeg9n It oscillates even without audio source connected, but I think it's not a preamp problem bacause if I switch to bypass (FV-1 is bypassed, only input preamp to output preamp) there's no...

If you are getting a loss of frequencies, the origin might be in your input signals. Well, maybe expressed myself wrong. I meant losing the stereo panorama and it sounds strange but its normal, I think. Delaying one channel relative to the other about 10ms gives stereo impression, but what if I don...

Okay, so maybe another thing. If I want to send signal eg. to delay memory I must sum left/right channels before. But doing simply two "rdax adcl/r, 0.5" gives a bit muffled sound. Is there any simple algo to add channels without losing much sound details?

Hello,
If there is AVD supply and DVD supply (I suppose its DigitalVDD and AnalogVDD), how about GND pins? Isn't it better to connect some of them to 'digital' ground, and others to 'analog' one? If so, which ones?

Honestly, I need 1ms accuracy. It will be beat-synced fx.

You mean 2^17/(2*pi*f/R) formula?
If the rate register is 9-bit, there are only 512 frequency change "posibilities"?

Hello, I got a problem with controlling LFO (sin0). Here's the code: skp run, 1 wlds sin0, 0, 32767 rdax pot0, 0.1 wrax sin0_rate, 0 cho rdal, sin0 wrax dacr, 0 And, when I set pot0 to 1 (sin0_rate = 0.1), period of generated sinwave is ~340ms. But when I set pot0 to 0.1 (sin0_rate = 0.01), period i...

Hello,
How to make pseudo-stereo output from mono input?
