Crackling sound when listening music
Hey,
The app makes some crackling sounds in the background when enabling any option on the app while listening Spotify. I have tried the "reduce clipping" option but it doesn't help.
My phone is OnePlus 6 version 10.3.6
Perhaps you are using a Bluetooth headphone with a sample rate not supported by one of the libraries used or maybe a different sound tuning app on your device is causing trouble. You could try following the steps provided in the third paragraph on this page to fix possible issues with Bluetooth.
Same problem but in youtube music and when open another application. I'm using KZ ZSN PRO device
How to i can send you log ?
@FosterG4 I am afraid logs won't be of help. I would need to reproduce the issue myself or need someone who is willing to help testing a few builds. You can ask contact me via email if you wish to help out.
Hi, thanks first of all for your hard work on this project. Sadly I have the same issue with crackling noise while AutoEQ is on, independent of IEM/Headphone-Model. (Tin Hifi T2, Ath M50xBT2, Soundcore Q35...) I'm on a Pixel 4a with Android 12 on the newest stable update.
Volume, max cache etc. has no impact on the issue, neither does any other option turned on or off.
Edit: Reducing the AutiEQ-Strength below 100% seems to fix the issue on my Tin T2 IEMs - Looks like there is some distortion introduced when applying 100% on the Pixel 4a - Will test further with different Headphones and report back.
Edit Edit: EQ-Strength of around 75% on Audio Technica M50xBT2 makes the crackling inaudible - Above 80% it's clearly audible.
Soundcore Life Q35 sadly having the same issue, so the issue is definitely not dependent of the headphones used.
Wavelet Version 21.12
If anyone else has the issue, the track I use to check is Deftones - My own summer around 50s mark 'guide me to shelter' it crackles like hell on the sibilant when using AutoEq. Without it's fine obviously 😉
Pittvandewitt contacted me and the issue is now fixed, by using the inbuilt limiter of the app at -4,5db. Seems like it's Googles fault.
Thanks anyway for the help and the awesome job.
I know this whole thing i should now be marked as solved, but actually is the wrong buffer size often the reason. Just in case someone else got the same problem and it's still not solved in future updates :)
Read about the buffer size elsewhere and I have adjusted it accordingly to max, but on the Pixel 4a at least it didn't solve the issue. What finally did it, was, as mentioned, the adjustment of the post gain limiter.
On a different device adjusting the buffer size can be a solution afaik.
If this issue is specific to pixel devices should it be listed in a separate section on the troubleshooting page? I spent a few hours debugging what seems to be a very similar issue on my Pixel 5 with Sony WH-1000XM3 on Android 13 (GrapheneOS to be precise) - I was getting noticeable clipping with Wavelet enabled but it would go away with it disabled. Increasing buffer size to max didn't help but turning on the post-gain limiter as suggested above helped. However, I'm not sure what the other limiter settings should be, I just took all the defaults except for Post-gain which I set to -5dB.
I am experiencing the same issue with different devices and different headphones, so it is not device dependent. The crackling/distortion is very light to hear, but it is clearly there.
The issue disappears, setting the post-gain of the limiter to -5db.
I have a question though: what about a pre-gain setting (before the EQ), as we usually have in other EQ software (EasyEffects, Equalizer APO and similar) ? or is that already happening, when we load an AutoEQ file?
