Hi Alex
cool code snippets. I don't have an FV1 board in the bench at the moment, so I haven't tested them, but I will as soon as I can.
Thanks for the code

Re: I2C Messages Sent by Spin to EEProm
Hi, I am wondering if there is any documentation of the I2C messages sent by the FV-1 to the EEProm chip for program loading. Like a description of what messages are sent out and what the FV-1 expects to get back, as well as a timing diagram if possible. Please let me know, thanks! If you are inter...

Now I'm intrigued.... when is the next chapter released?

Re: Pseudo-stereo alghritm?
Find some Internet tutorial about filters and you will find what poles and zeros are.
If you use the Gerzon scheme in the same paper, you will only need 2 identical All-Pass filters.

Re: Pseudo-stereo alghritm?
"sound like stereo" you mean stereo output to the L and R channels? It depends on the effect you are working on. But at the end, you need to create some differences between left and right channel. It can be adding a delay between both, having a different filter, some modulation between the...

Re: Pseudo-stereo alghritm?
Maybe let's start from the beginning because I'm not sure I understand what you need.
Do you have stereo input, whant to process it in mono, and then generate a stereo output again?

Re: Pseudo-stereo alghritm?
What you describe is simply adding L and R channels. Nothing is going to be cleaner/simpler than this. If you are getting a loss of frequencies, the origin might be in your input signals. Maybe some comb filtering happening? Just guessing. You can try to increase the 0.5 to get more volume, but be c...

Re: (1-k)*sample[addr]
Where do you see the (1-k)*sample[addr] piece of code? Not in the snippet you pasted.

Re: Latency in FV-1 hardware
Let me ask another fast question without making a new topic. FV-1 has delay of 1s @ 32768Hz and I need eg. 800ms, so i declare "mem delay 26214" (32767*0,8), but max delay is still 1s. I know, I can change delay time via pot, but I would like to limit delay space by software. Why is that?...

There is a white noise pseudorandom generator code, but I don't recall any pink noise. Just search in the forum for pseudorandom

Re: RMPA Instruction - confusion?
The symbol 'delay_r' is a moving target on each execution that address is moved for each sample. So every execution you can simple read from the ADC and write to 'delay_r'. So whilst I agree with the comment and what it's doing I'm not 100% sure it's doing what the comment suggests. delay_r is the ...

Re: Stereo delay
I suppose square. Just look at the datasheet
