Spectrum ballistic (display buffer)

DanH

@Christoph-Hart @ustk so on Windows do I need to add ipp when exporting with this new Analyser module?

Lindon

@Christoph-Hart said in Spectrum ballistic (display buffer):

@ustk Yes I've added this recently. if you click on the edit button (where you can assign an external slot), you can see a new entry called "Edit properties". This opens a JSON editor that lets you change the properties:

Be aware that these properties are not stored in the network, but you can set them programmatically using the scripting API:
// only works with ring buffers that you have registered as external.
const var dp = Engine.createAndRegisterRingBuffer(0);

const var mySpecialProperties = {
  "BufferLength": 4096,
  "WindowType": "Triangle",
  "DecibelRange": [
    -90.0,
    0.0
  ],
  "UsePeakDecay": false,
  "UseDecibelScale": true,
  "YGamma": 1.8,
  "Decay": 0.2,
  "UseLogarithmicFreqAxis": true
};

dp.setRingBufferProperties(mySpecialProperties);

Can I apply these setting to an EQ displaying in a FloatingTile (not in ScriptNode)?

Matt_SF

@Lindon I think I've done it recently (just for testing). I've simply copy/pasted the JSON datato the empty floating tile data.

DanH

@Matt_SF you mean like this?

Matt_SF

@DanH I think so, it's been a while and I didn't spent much time on it

DanH

@Matt_SF ok thanks! Doesn't do anything for me sadly...

Matt_SF

@DanH I'll try again in a minute, I'm just compiling the last commit

Matt_SF

@DanH Yep you're right, it's not working... Maybe I'm confusing this with something else I did... If I come up with a solution I'll post it here.

Matt_SF

@DanH @Lindon this is one way to do it, but it uses a scriptnode analyzer :

sadly not a path I can go down now...

DanH

@Matt_SF Thanks. A potential solution perhaps. It's still glitchy like @ustk pointed to originally and I'm still not crazy about the blocky lines Any chance of reinstating the old Analyser on top of these or adding a curvier Window Type @Christoph-Hart ?

ustk

@Christoph-Hart This bug hasn't been yet resolved... Is it still the best way to draw a buffer, or something replaced it?

This topic from above seems the best example for reproducing it:
https://forum.hise.audio/topic/5791/spectrum-ballistic-display-buffer/17

ustk

@Christoph-Hart Any idea to sort this out?

ustk

Has anyone ever released a product that uses a buffer drawing, or am I the only one counting on it at the moment?

Matt_SF

@ustk I'm working on a project - far from being released - but I sure am counting on this one :)

My current update uses the parametric EQ’s analyser with laf and source code tweaks because drawing the analyser in a panel was buggy. I would love this to be fixed however.

ustk

@Christoph-Hart Even coming back after months here I still feel like a beggar asking for fixes and this is very frustrating... This would make a great Christmas present though!

@Christoph-Hart Bumpy bump

The problem with your snippet is that there is no synchronization between your slow Hisescript loop that creates the path and the audio thread that pushes new signals to the FFT - this is why I added the special createPath() method (that also tries to reduce the path points to optimize the drawing performance).

If I use the ScriptRingBuffer.createPath() method the artifacts will disappear completely and I can render it with 30fps.

Edit: the second example you posted somehow creates the glitches with the createPath method too. I'll check again if I can spot something.

Christoph Hart

Alright I think I solved it.

The problem was indeed a multithreading issue, but not between reading and writing (this was already handled), but between reading into the buffer and then applying the FFT. The createPath() could be called between those steps and then you would get some glitch values (I could reproduce it very reliably in Debug mode with the 32768 sample size).

I've fixed it now so it should not glitch anymore, but I might have to do a bit of profiling to find out whether the two threads wait on each other for too often.
