Bug: Static noise appears over a long period of audio processing #224
Comments
|
The bug is likely related to #225 and probably fixing one of these will fix the other. |
|
@nodeful, I'm getting this bug running through a Thunderbolt 3 port into a Caldigit TS3+ dock with speakers plugged into its 3.5mm jack. As others said on the previous issue, it goes away temporarily if I switch audio source away and then back to eqMac, and then returns after a couple of minutes. |
|
@nodeful I'm running into the same issue with my Revonext QT2S headphones, my KZ ZS10 Pro's and when I use my Bose QC 35 in wired mode. I might be wrong, but it seems like the issue gets worse (appears sooner, progresses quicker) when the bass levels are boosted significantly. I'm running a 2019 15" MacBook Pro. |
|
What Sample rate are you guys using on the output devices? You can find that in the |
|
eqMac is at 44.1K the rest is all at 48K |
|
What if you set everything to 44.1K before running eqMac? |
|
I did that setting up to 44 before installing actually is happening anyway I'm using iTunes on Catalina and if you leave the music running it comes worse the noise |
|
Switching between output the noise go away immediately however after a while comes again |
|
Maybe I'm wrong but on eqmac2 I could it switch on the mac (top bar -> sound icon) switch between output with this new version I can do it but after select for example from "eqmac" option to "Macbook Pro Speakers" nothing sounds even if I increase the volume, not sure if this is a bug or not, but as I said on previous version I was able to do that and the sound coming out from the selection |
|
@nodeful Tried switching to 44.1K before starting eqMac. Same issue still appeared after a while, although the crackling seemed to be of a higher frequency, although that might be unrelated. Let me know if there's anything else I can try or if there's any info that would help you. |
|
Thanks for the response. I switched the speaker to 44.1k with Audio MIDI Setup. This seemed to help at first, but the problem came back (maybe it gained me an extra minute or so). I've noticed that eqMac is set at 44.1k (or 48k) 2 ch 32-bit float, while my speakers can only be set to 44.1k/48k 2 ch 16/24-bit integer. So could the problem arise as eqMac is trying to convert the float sound stream to int? (forgive me if I'm nowhere in the ballpark, not really my area!) |
|
Furthermore, when listening through my Sony WH-1000XM3 headphones, there is no static build up. The headphones' format is 48k 2 ch 32-bit float. Even with eqMac set to 44.1k 2 ch 32-bit float, it works fine. So the issue only seems to arise with the float/int difference. |
|
Same here as @NielsKersic has described |
|
Experiencing the same symptoms on a MBP 15" 2018 on Mojave, using the integrated speakers of my external LG display (connected via HDMI to Thunderbold3 port)
Output devices:
As others mentioned, it goes away if I switch sources. Also, this never happened to me with eqMac2, which I was using up until now. |
|
@nodeful, I figured out and have a fix for this issue (I created an app similar to this years ago and had to solve this issue then). I am not a Swift guy, so you will probably have to remove some semicolons. I should have a chance in the next few days to upload it. How would you like me to post it (I have no idea what IssueHunt is)? |
|
I would like to add my config to the list, I've encountered this even just having/using the built-in speakers.. (using eq 0.2.2), this somehow didn't happen when I was using "0.2.0" version (or might not have noticed it). Also happened while using an external headphone.
[UPDATE] If you actually leave it playing, as it degrades over time, the music/sounds becomes robotic in nature. And more static noise is introduced as it degrades more. |
|
@darrenw2112 that's awesome man! Edit: And don't worry about formatting, just want the bug to be fixed. |
|
Downloaded 0.3 today. Sounds great thank you. But, this issue is still happening only this time the sound gets slightly distorted but doesn't cut out. It just maintains a crackly sound. Clicking 'Reset Playback' fixes the issue, but it comes back after 15-20mins of continuous play. Also, the Balance L/R fader/slider doesn't do anything. I am on latest Catalina with headphones. |
|
I can confirm that the crackling sound still happens after some time.. I haven't logged how long yet.. but issue is still there. Clicking the reset/resync button fixes the issue temporarily. By the way, i'm already using eqMac 0.3.1 with 1.1.0 drivers. [UPDATE 1] [UPDATE 2] [UPDATE 3] [UPDATE 4] |
|
@nodeful I will try to post this today. |
|
@nodeful I submitted the pull request. For some reason it shows a lot has changed. The only changes are in: |

@darrenw2112 I will take a look this evening, my laptop has died unfortunately waiting for a replacement at the moment so wont be able to test for a little bit |

Hey everyone 👋 |
|
Note that I changed your init back to the way you had it because the rates that were reported in your new way (using the mix bus) did not reflect what the input was set to. It always reported 44.1.

I'm currently running in 25+ mins already and so far I haven't noticed any crackling or static noises. I will do another update at around 1+ hr mark. Checking CPU usage, Activity Monitor is reporting an average of 3.5% with average of 15 threads running (main process only). |
Ok after doing some additional checking in the Activity Monitor, I noticed CPU usage on 2 out my 16 hyperthread cores was at more than 10% so I went to find it. (NOTE: No music/audio is playing while I was checking) 1st... "coreaudiod" was spiking between 10% and 20%, is this normal?? 2nd... After quitting eqMac "coreaudiod" went back to 0-0.2% usage and at the same time the audio driver was not removed from the enabled audio devices |
|
I have been running for several hours and coreaudiod < 3% with eqMac around 5% (same as in Xcode). |
Hmmm mine is at 10-11% average (for coreaudiod) CPU usage with or without music playing. MBP Processor: 2.3Ghz 8-Core Core i9 What's your processor? |
|
By the way, I'm already at 45mins mark with music playing using Spotify and MacBook Pro Speaker.. (i'll test using headphones after a couple of hours) So far, no crackling or static noises heard.. audio quality is still at 100% for me.. |
|
MBP: 2017 -> 2.9 Ghz Quad-Core i7. |

Currently the way eqMac works is it processes audio all the time, even if it's silence, there's no real nice way to fix that without going absolutely crazy in to optimisation, which is not something I would like to focus on right now personally. For me on my 2.3 GHz Dual-Core Intel Core i5 eqMac together with CoreAudio uses around 5-7% CPU on average which is totally acceptable for me. You have to take into consideration other apps that might be interacting with CoreAudio in any way, even if it's not apparent straight away. Also higher Sampling Rate devices and more complex protocols like Thunderbolt can increase the load on CoreAudio in unknown ways. Regarding this issue, let's see what some more people will report, but so far looks very promising. Congrats and thanks @darrenw2112 couldn't do it without you. Would be nice to chat with you in https://discord.eqmac.app to understand how you fixed the problem in more detail :) |
Thanks for the update, I do understand the possible intricacies of coreaudiod. If I can find extra time next or next next month, I might try to help out on the optimizations. 😁 Thanks @nodeful for creating such a great app and thanks to @darrenw2112 for finding a fix to the audio crackling/noise. So far, running at more than 1hr mark, audio quality still at 100% 😊 |
Oh no! I think a new bug was introduced... no sound coming out of my external port using a headphones. It also stopped working while trying to switch between "MacBookPro Speaker" and "External Headphones" NOTE: Using internal speakers past 2hr mark, still no crackling or static noises observed. |
|
For me static noise always started after 5 seconds and sound was a total robot mess in just 10 seconds. Updated app to 0.3.2 and driver to 1.1.1 and so far so good, no problems anymore. CPU usage is 2-4% (i7 8750H) |
|
I occasionally (seems to happen much less anymore) have a crash when switching inputs (I believe this is in the init function). Also it would be great if the program would not switch the output device when a new one becomes available. |
You should probably create a new issue or find a more relevant one: https://github.com/bitgapp/eqMac/issues |
|
I know, I was just responding to the comment earlier about it stopping. |
|
Hi, I installed the new Version and driver and what should I say - it's gone. The crackling is gone completely. I listen now 3h to music, YouTube and other things and all works as aspected. Thank you, @darrenw2112 for the fix and @nodeful for the implementation. :) |
|
Thanks for the feedback everyone. I made the v0.3.2 release public now. Seems like this specify issue can now be finally closed. |

I've been using eqMac for the last few years and I've never had any issues with it up until very recently. I'm having this issue on Mac OS High Sierra - the audio starts crackling after about an hour of using eqMac and it would only resolve itself if I quit and restart the app. I had to recently reset my PRAM and eqMac is completely unusable (noise crackling when changing the volume up or down, bass is constantly crackling and the Advanced equalizer makes everything worse. Mac OS Audio devices Format 48,000 Hz. |

Describe the bug
Reported in issues: #36 #79 #152 #174 #180 #187 #199 #210
I (the developer) have never actually seen this problem occur to me, probably due to the specific hardware setup that I have. However, many users have reported and this is a critical issue to fix.
In #180 user @ekarlo have done a lot of work to mitigate the issue with the old eqMac2 release.
Most likely issue relies in the Sampling Rate mismatch and the slow drift of the Ring Buffer when processing the audio.
Probably also related to the sync loss and audio latency added reported in: #118 #144 #212
Need to look into it more.
Steps to Reproduce
Waiting for users to report their hardware setups to achieve a similar setup for reproduction.
Expected behaviour
The Audio should stay clear no matter how long eqMac process is running for.
Setup information:
Waiting for feedback from users about the setup that they use.
