Introducing DSPi | A powerful, user friendly and open source DSP for less than a cup of coffee

when switching between EQ presets the EQ graph changes but EQ Bands do not change. I have to turn off and on the individual EQ Bands to see the new preset.

Just finished my amp build and have a ssd bay that will be a perfect fit for the dspi and and dacs. Really happy with the TPA3255.

Nice re-use of a computer case. The only thing is that it is made of steel so it acts as an external core to the output coils and wires as well as the power supply. This will introduce some non-linearity, and worst case you also get coupling between the switching noise from the power supply and the class D amp and the output signal. But then, your wires are twisted, minimizing the effect.

The amp and PSU are actually mounted on a grounded 2 mm aluminium plate inside the steel case, and the PSU is an enclosed Mean Well unit. All supply wires are twisted and ferrites added on the 48 V line. The system is completely silent at idle, so any coupling or magnetic effects seem negligible in practice. Appreciate the point though.
 
Okay, (aside from the elements to add) there's still quite a bit of work to do on the console:

For now, I see two small things that could be implemented quickly:

- The graph could extend further down, or the size of the elements could be adjusted. On a large, high-resolution screen, the graph is too compressed.

- When performing filtering/EQ, the data (Fz, Q, dB) must be entered manually. The ability to modify the data with the mouse wheel by positioning the mouse over it, or with small buttons (+/-) on the side, would be appreciated.

Since the DSPi isn't solely intended for extended use (DIY active speaker crossovers), while awaiting the development of a simplified interface and one for advanced use, it might be helpful to explain that the input PEQs are primarily used for room or headphone correction (or possibly for adjusting tone, bass, etc.).

For those using 2.1 systems or with more extensive applications, a dedicated crossover section could be a valuable addition.
 
Thank you very much for the bug reports, everybody. I will push a hotfix shortly. :)
 
As for the size of the graph its fine for me because designs are through acoustic measurements and display is just necessary backdrop.
I'm not sure about larger display and reducing rest of display info below it. maybe its a good idea just cant say for sure

set vertical range to 8db and graph displays +/- 6db. +/-8db is hidden.. same with a few others

Yes indeed. But these are still special cases; perhaps adding a vertical scale of "2dB" per line in addition to 1, 3, 5 and 10 dB would solve the problem.

You're right, it's certainly an accessory, but nevertheless, it needs to remain "readable"! I'm on a 4K, 31" display and I assure you that as it is, the graph is very uncomfortable to read.
 
Furthermore, who knows, just in case (let's be crazy), with a frequency response import function, the ability to have a higher pitch could be useful... but well, that's more complex to implement, and there are indeed software programs for that! haha ;)

Yes, no "Q" on low/high Pass/Shelf...

No Q but for some reason this happens and I don't know why
 
I have just pushed a hotfix that should address the vast majority of reported issues, while implementing several suggested functions.

Here are the changes:
  • Fixed: Q values now display correctly for all filter types
  • Fixed: Channel Editor filter bands now update correctly when the active preset is changed
  • Fixed: Filter response graph no longer displays curves belonging to disabled channels
  • New: Gains display up to two non-zero decimal places and Qs display up to three
  • New: Column padding adjusted to comfortably accommodate longer values
  • New: Filter response graph is now vertically resizeable by up to 100px
  • New: Scrolling while the cursor is over the vertical axis labels now zooms that axis
  • New: Show/hide vertical axis dB unit labels
  • New: Scrolling over frequency, Q and gain on Channel Editor pages now increments the values in two stages; 1Hz/0.01Q/0.01dB when slow and 10Hz/0.1Q/0.1dB when fast
This might be one of the few occasions on which the Windows version is actually ahead of macOS! :P
 
Even though I'm watching the Six Nations final, I'm also testing the console! Clearly, yes ! great job, there's almost nothing to criticize!
But would it be possible to have the option to increase the graphics resolution by another 200 or 300 pixels? (blushing smile) ;)
 
However, there's a problem with the gain slider. It's jerky, and you have to try several times to get it set correctly. The ability to manually enter the value would also be very useful.
