3.10 Can't find ATK binaural decoder kernels

[johncburnett]

Using the latest builds of both SuperCollider and the plugins, I am unable to load decoder kernels other than UHJ (in either scsynth or supernova). However, with the same build of the plugins, these kernels work fine in 3.9. I get a version of the following error for each of the binaural decoders when trying to instantiate them:

CALL STACK:
	Exception:reportError
		arg this = <instance of Error>
	< closed FunctionDef >
		arg error = <instance of Error>
	Integer:forBy
		arg this = 0
		arg endval = 0
		arg stepval = 2
		arg function = <instance of Function>
		var i = 0
		var j = 0
	SequenceableCollection:pairsDo
		arg this = [*2]
		arg function = <instance of Function>
	Scheduler:seconds_
		arg this = <instance of Scheduler>
		arg newSeconds = 12.971545154
	Meta_AppClock:tick
		arg this = <instance of Meta_AppClock>
		var saveClock = <instance of Meta_SystemClock>
	Process:tick
		arg this = <instance of Main>
^^ The preceding error dump is for ERROR: Samplerate = 44100.0 is not available for cipic kernel decoder.

I am using macOS High Sierra 10.13.6.

do you have adclib installed? please uninstall or update it first if so. it overrides Float:asCompileString.

[nhthn]

wait, sorry, that's not it. i think simply updating your version of the atk-sc3 quark should do the trick.

[johncburnett]

Hey, thanks for getting back to me. I'm definitely using the latest version of the quark (4.0.2).

this appears to be the same issue as ambisonictoolkit/atk-sc3#73.

[johncburnett]

It appears so. I hadn't thought to check the issues in the ATK quark repo, but glad it's been addressed by the devs. I assumed it was a path issue.

I tried changing the directory names of the CIPIC kernel to "44100.0" for the sample rate and "nil" for the block size (which is what ATK seems to be querying) and was able to load the HRTFs successfully.

It seems that the block size path being nil must be a separate but related issue, as I imagine the 512 block size for the HRTFs is totally independent of SC's block size and not beholden to the .asString problem.

@johncburnett, I see you're using SC 3.10 rather than the current release, ver 3.9.3.

As you can imagine, we make an effort to keep the current stable release of the ATK in sync with the current stable release of SC and SC-plugins.

As @snappizz notes, you've encountered a known issue: ambisonictoolkit/atk-sc3#73. @mtmccrea has merged a fix made by @blacksound to address.

At the moment this and related changes have been merged into https://github.com/ambisonictoolkit/atk-sc3/tree/sandbox/hoa, so aren't in the main dev branch, yet.

BTW, we are pushing ahead with HOA development as our main focus....

Hi @johncburnett I've pushed a fix to this and incremented the version to ATK 4.0.3.

Please uninstall the ATK and reinstall the quark (alternatively just run Quarks.gui, navigate to atk-sc3 and click "INSTALL" on version 4.0.3) and let us know if you have any further issues before closing this issue.

Thanks.

thanks Joseph & Michael! closing as this issue has been resolved.
