Eqmac: Noticeable latency

[alexkreidler]

I recently discovered eqMac, and it is really helpful when listening to music to pick out different parts. I would like to use it all the time, however, when I use Logic Pro X, there is a noticeable difference between routing directly to Built-In Output and the eqMac2 devices. At the time with Logic, I was using a "flat" eq. When playing or recording, this latency can throw you off. Is there anything that can be done to improve the latency and speed? Maybe when on a "flat" eq, don't do any processing, just use the source input stream.

Thanks for a great app! I hope you all have some ideas because this would make it better for everyone.

I am completely rewriting the app as we speak. I am going to be using a completely new way of routing the sound. We will have to see how the new version performs. Not going to invest much more time in this release. But the community is free to continue working on this repo

Thanks for the update. I'll leave this open for now to track progress specifically on latency. I'm glad for such a great app and really appreciate the work you do on it.

First of all, I would like to apologize for the lack of communication and responses to the current issue and all other issues in general.
I have made a conscious decision to focus most of my free time and focus on developing a more modern and new version of "eqMac". This means that I can't spend too much time looking back at old codebase and trying to make every user happy. This was the main reason I made this repository open-source, in hopes that other developers might help to sort out some issues and iron out all the bugs. Unfortunately, there are very few developers that are proficient in Core Audio and Objective-C or maybe they are just not interested in this repo, which I can understand.
I promise that the next version will be much more polished and I will make some sort of a mainstream system were solving issues will be very easy and quick. Just sit tight and wait for a new release this coming summer.
Thank you to everyone who gave "eqMac2" a try and I hope I won't disappoint you next time :)

Heres a sneak peak of the UI I am currently working on:

Hey everyone. Excuse me for the lack of updates. I have been really busy on the new version of eqMac. I am happy to announce an open beta release.
You can download it here: https://eqmac.app
There are a lot of known bugs that I could not fix just yet:

• Driver not installing from the first try. Sometimes need to restart eqMac a couple times.
• Complex Device switching logic is not perfect (for example when switching off the device that's currently playing, plugging in new device etc.)
• UI takes long to load (a lot can be done to improve that)
• UI dimensions are not synching properly
• There's a noticeable audio delay in the playback, so not suitable for video yet (I know where the problem lies just haven't had the time to fix yet)
• Sometimes the playback doesn't start, in that case please try to switch the output to the device you want and eqMac should try and build the audio pipeline again.

So as you can see there's still some work to be done but at least it's a completely modern tech stack that I am fully willing to work on: 100% Swift, User Space driver and a Web UI, instead of C++, Kernel Drivers. As I said, should work on Catalina and should not have any pesky ear drum blasting volume bugs (at least I didn't come across any).
I'm open to feedback and issue reports here: https://github.com/bitgapp/eqmac
That repo will become the main repo for eqMac and this repo will be archived eventually.
And yes it's called just eqMac, not eqMac3 :) And it will stay that way forever.

Hey everyone 👋
I will be open sourcing the new version of eqMac, therefore, I am closing this issue and repository as I will be transfering nodeful/eqMac2 repo to bitgapp/eqMac
Please bear with me for the next couple of days as I setup that new repo. The eqMac2 code will be living in the old-eqMac2 branch if anyone is interested in referencing it for whatever reason.
Please try out the new version and report bugs to the new repo.
Thanks for using eqMac.

I'm moving the discussion around this issue to #225

nodeful, the older version of eqmac 2 worked perfectly fine for me. I don't why the new version doesn't work for me in CAtalina
