Soft clipping(?) in lower volumes. (Idk the term for it)


Recommended Posts

Build #: v3-build-853-arm64-play 

Device: Xiaomi Redmi Note 7 Pro

Android System: Android Pie (Android version 9)

Custom ROM: Pixel Experience - Pie - Plus Edition , September Build

Steps to recreate: I don't know how to recreate as it is just there.

Settings: last.Poweramp-settings

Bug/Issue: There is audio clipping when playing music at lower volumes. For example, with instruments like Piano, when a key is played the audio cuts off after the peak of the note is heard, the decrescendo/diminuendo of the note just disappears, it sounds the audio is turned off and turned on again and again or it feels like the power to run the earphones is not enough from the phone but that is not the case. I am attaching Dropbox links two audio recordings for comparison. They are recorded by putting the earphone directly on the mic of another phone so the quality is not the best and has background hiss but the problem can be heard. Please listen at higher volume to clearly hear the difference.

Using wired in-ear earphones btw..

The track/song I am playing is instrumental of "Dango Dai Kazoku". Youtube link for reference: https://www.youtube.com/watch?v=jWWw3JPMRt8 . I am not playing directly from youtube, I have a 320 kbps file of the track it is just for reference.

Before checking any further, could you ensure that all audio processing is turned off (EQ, tone, limiter, stereo effect, reverb, etc) and Settings > Audio > Output has been reset to default values.


Yes, every audio setting was reset to default and eq, tone, stx, etc were all turned off except for DVC (Just checked if turning it off help, it doesn't). But the issue is still present regardless of eq processing. Stereo effect/expansion does help a bit but that's should't be the normal way of getting around the issue, just a temp fix.

@andrewilley @maxmp

I tinkered a bit with the audio output settings. The issue goes away when using Hi-Res Output for Wired Headset/AUX with DVC turned off for this wired output.

Just letting know, it might help in some way to pin point the issue.

I am blaming the Custom ROM for now as it is a custom ROM and it's implementation of audio mount be different.
