[SOLVED] Blackhole and Sound Frequency Bands

[tim_f]

Hi,

My patch uses sound frequency bands to smoother to calculator into a Rutt Etra actor to control x-extrude, wire frame size and scale x. 

- I have blackhole 16 channel installed on a mac m3max. 

- I have a midi audio set-up on the mac for a multi-output device which is both the blackhole and mac internal speakers. 

- In live capture settings I have it set to blackhole. 

When I set up the patch it works perfectly. When I save it exti izzy and come back to it the sound frequency bands don't recognise the music playing on the computer after turning on live capture. If I set up the patch again it works. Any ideas? or is more information needed?

Can you post the patch?

Is your Multi-Output Device setup as the default audio output in Audio MIDI Setup?

Hello,

I would recommend using one of the Core Audio plugins to stream your Blackhole data as an actor: AUSoundInput 

For me it works perfectly (for example I output Movie Player sound from Izzy into Blackhole, and grab it back in the same patch through this actor, it enables sound treatment of movies that the Movie Player doesn´t offer -yet?- in izzy) and I never need to reconfigure it as Blackhole remains the input parameter no matter what happens.

the mapping of channels offered in the actor works fine!

@woland - ah the simplest overlooked. Once set the default output in Audio MIDI setup got a fix.

Thanks.

@jokolski - I have a fix with the default for audio midi setup but interested to dig into this actor a bit as well. What actors accept the audio output? cheers.

@tim_f Hi, ah, I just realized the frequency band actor works with the default mac device, not with a variable audio input. But you'll find quite some actors with audio input in the audio category of the actors list, such as all or most actors starting with AU on macOs, they come from the default Core plugins, at least on recent macOS versions), as well as audio plugins you might add yourself to your mac sytem (for example through the MPluginManager - opens quite a big range of possibillity). 

For example, I had a multichannel video and wanted to manage the gain and routing of each sound channel in Izzy. The movie player doesn't allow that, but using Blackhole as device for the MP and as input in the AU Input actor, I was able to do pretty much anything I wanted to the video´s sound. Have fun with that! 

Best,

Jo
