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

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

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

@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.

sadly not a path I can go down now...
-
@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 ? -
@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 -
@Christoph-Hart Any idea to sort this out?
-
Has anyone ever released a product that uses a buffer drawing, or am I the only one counting on it at the moment?
I can't help pressing F5 in the forum...
-
@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.

@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.HiseSnippet 2245.3ocyYEzaajaElx1TNRqSPVffhdbpwdPAvqxLxxN1cQajksksPrcDr75cMBVDPMCkDgmYn5LTwVcQ.ROz+.81dq+B58dK+E5Oidp6+fzGImQyLxRwxt6FTYaLhju2ie7wG+dONtU.2lFFxCP4Jb1nATTtUvsG4K5uaeByG0bOTteCtQiyLpOraWZfwdAjqX98L1.Uez.RXH0AkK2hGHkMWgkPpO+7KpSbI91zjtPny4La5QLOlHo2V0dIy0sAwgdFyKkzUq0zl6uK2kODv0hXSz.h8kjdzSHRwV.ixkeeGlfGzVPDzPTtkpycF0tO+Jes7myBYcboxFVn1fgzc2f65HQrrWzt8YtNshW+gHvJsR7FKp8FOAeLygMt+DuxiUCXjnQZ+QtExBuEy.OqzvyLE7lBjxkBRXMj9Rba6.1.QxHR77E3l9BZPWB31SCkSF5sGKbfKYjdGDPCN2BfSVaDzB+0Ew6xAU8Ek8HWRaD.MFapRVULMWyXSSym9MEAwB4tzx1tTRPInihvtTnv3sj.iVDepqkwevH1V8nhc4dC39PiRqpGdUPmDUBgcWaJnhJdSpPFf1VMboU03znw2qTun1RkcHBR4NJAMASns0MrQIIrSqw.hnuYJTZGPgcnVPux0S.smgzllv7DqVHUzB1yEmxGJX9zRcG5aKXb+R8dZwerXgdRAzQpkzOBKyCH98nf8fQcfyKJyK5yBSgg0LdM7G7qpe.2eGyQBhjNNjx50WT5o+.HV4MjKj2IW+oAl7TSvtDW2NvwiDjo.1ydlZk.q0jYNxeIs9ozP1el5D4lrLqTcMCKIjuEsHwpHksXA49XmtSSb0v5elXoCR2oaZOe7J9HtMwsNenuSHrwI8PkAGjUYsi5qsTdBym9MorZ.cfbyoTj2I10HHAZmSo0M0NsnOw9HCt+IbA8UQNqhuqnwjC0s6TGSF4DvccktfoLrdV+DJVxenWGZvZvQ.2gzwBBjOYoLvylxHMilsNPNkfb+l9LwqFP8mEOGJJ5G9121bOXeQxyD0GH2.ZffIgPt8nuEHs0rNEv6QCuTvGnjM5fMvCKTi9vXNI4F.hALOO.q2LPWmlWeT5FWIC4G2gweqVeUH+3dd+eoFJE82RZf.DubmgtDQV1XYJnnA.+cFJPIaleHSLJcJpewnnmWH9k3VLgc+oiwElBFgckeMvXThsGh2GNmZKR.3R3Fe+mgrX40yewnHFXNkS9J3Dd9IyecFAlEUdqbvR4VSn8uV.mJKiOU.DN662CHuiHc1KbvITwU7fKKsZnRo2z8ZU1EPXIuZCdvUj.mnSrgmwaQBfJOfbhgk5RbCoYy8cZcyImhc7cNk1iEBpbJTtTprQoUyZ9TyJ6z4Mp8.pMi3lbVEryOVzvXUsBGQ86I5u5u2XKqsqr1yd15Ud9laslb7ui46vuRtA.itZcWHsgGw2+PRP.KbUkH6AltC08TYJLPnWC8Y.bulRtX02gu.O+AkveaHsEkbInCYDHrx2DOPjgZCb5RCIBFpG5hCHddDnGKsEWMVaHKWrtGw6QBXh9dL6FAz+zNWCnSahhuC7EfCWtMk3hR7Dklh2Abefu9NpwjILFHS0DPgXAHxqTHwafK8TXKaMiNtb6KaCYSuIq+.cXecoDkr6CtZpa38I4P949jn0mlHPWFSuiIh.FvLigSS5Bs1MBcwmlhZaJaK4hZS8cTM9H7IZPq3yjxAshGLI8Rt7QqK.NhHlQ8oTHCRGdc90pTEOF2IUb6tcPpUeBQ3usFZtryivWMN99lV4w2zJOJxJscYNz.kMVAqJd6H9K8ugEt3C2AKbHaJVHJ26sXgu.qOiLMCLWKhkwNxyTYT9u+S+z+9EnHdOIm7BQeG1kzDvITgnyAlNYFJvRvw8xlncbc4WIS6yhxcALyp9ZwcGMnO2mYK6RKQbrzNdPsbh3.pCIgmQXtxjcvbyc.fgaPrgn5Qxp.kIHkEy.YinAksGmUJCtRRLHCukFI9Rh5fTX98TkkHuh3hxwUWqKZ1zliGZCW5TlaFcioOfVN0v2sYSt1coWGWO0D4nlrGncSeG50xzteMTjVRFF4wlwsfo5Xl+458Qrby.cL45wsqBsaKnCjrOx1.kpxokWV.BEkQOTJilOwn4wUxZ0BPGlR59TV9IfErL0erptsok0l.OykzqzdPs.Upr81lU2XyJUVu5VOeqMhtVpj.eH02dTLbJrzG+3yvHzaqgl05zJChxis1bFKzUTl23TYPIJi5n40GZMSe3A.Y6rM5R2lQkFYYbq9jvOwNwbYk7ppamDJIUpiPohvw3tcEYCseHl3SbGERKKG5ySXsJ+S5n5YB37R.a8+CH151Qbd8tp5UfjExqf8fm5WNxDHN8qc5VP+BYHBxc2i2zcMQ7V50wLWgppzksf6frf9vUyvykiBkvEaQfJuNmCUMpRhfxlCIOFpNQ7qd1ibye1iHDcuxa7+tm5dc657otc8CtKUMk5h1eU5KZ+U07HxR8xkGZvDTOXx+cX4q7oXEypaUrp41aVTdUghVat9VUKptt.J6kye+qm7x4n+nrTj4BoSTW1rv4Iw3b4DbVCeJbGUndJWZwIttRwCgZjfRYgm99EeIgERCJdV.SKbCHR6LvcdGWFOZ9JLL0RfkdIzrlGywwk1hCWkWEnGOwm8gvw4XhqG6e9Buzu17K9fZ8O127gPX+UUjN1voNxSEzKCTT2q51WYMqInWKj2z9zcN4f8MN5UHGZWxPWw4Sot1wtfGNeU1NKW.BMCW.pxs5Bd+4YcAHzuvtfCahRuTKLWkfmBPilXklFr0hlqB3KLNXmiOdmY3sQyJFA8yobFJeSZrt7sVs+rvYyZI378O4e7edwTvk51AZ7uLdu82cmK97bUQOhc.+M1QunEfo7Apd.RXe0+pmB3iksMrhuKiNiF3AYuw1Nt34oqSk6gNqeOzo58PmMtG5r48PmmeOzYqOoNx+qW6LTv8zYxgNZsuJKWtb66KeQcp2ZG5+B7.yn4CEdit: the second example you posted somehow creates the glitches with the createPath method too. I'll check again if I can spot something.
-
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.
-
@Christoph-Hart It's building at the moment so I'll test this right away.
Your snippet usingcreatePath()strangely crashes (before I could test the fix commit at least), but this might be because I was compiling at the same time, it's strange nonetheless...The reason I don't use
createPath()is because I want to perform my own interpolation in order to smoothing out the blocky look of the path. I remember looking to add a smoothing option to the method and not succeeding, but I might try again since this would be way more efficient if made natively rather than in a paint routine... -
@Christoph-Hart Nothing changed here
- I still have the same glitch when using a readBuffer,
- Hise still crashes after a few seconds to 1-2min with your snippet (so using
createPath())
-
I remember looking to add a smoothing option to the method and not succeeding, but I might try again since this would be way more efficient if made natively rather than in a paint routine...
Yes, definitely. Painting a path with thousands of data points in a 30 Hz framerate is pushing the scripting engine a bit too much.
I'll see if I can add a quick smoothing option but the
createPath()function should be used definitely (we'll address that crash later). -
@Christoph-Hart said in Spectrum ballistic (display buffer):

Only the number of pixels in a panel if downsampling, but still a native smoothing would be better for sure
getReadBufferis still needed, like for instance when making 3rd octave frequency bar graph or with other step values, you need to make a custom downsampling function.
I'm just not surecreatePathwill answer all cases
