Crack sound when playing a particular file

Recommended Posts

As the title says, when playing a particular file, in certain timestamp, I can hear a crack sound/audio artifact. It doesn't happen with other music files as far I am aware of. Also, I tried with stock and it works perfectly without any artifacts there. ūüėĒ

None of that. Tried with DVC off, EQ off, every audio effect settings off. Weird thing is that it doesn't happen when I am playing on phone speaker, and it happens when I am playing the audio file with MX player. It could be related to ffmpeg, since both PA and MX player uses that.... I am sending you the file link via private message if you don't mind

Not checked in PA yet, but the file as a whole is very close to 100% digital throughout. Have you tried reducing the PA preamp gain by 10dB or so, to see if that helps?

[Edit: In PA there is very small 'scratch' sound at 3:01. I wouldn't have noticed it if I wasn't listening for it though. Not related to EQ and preamp does not help. Also glitches using VLC on my PC, but not in foobar2000]

Oh yes exactly. So I wasn't the only one

That is a lot of hard clipping. Reducing the PA gain at this point isn't going to help much one afraid.

@John Titor Is this a downloaded file, or ripped from CD? Looks like gain was applied at some point that has oversaturated the levels. If it is from a CD, try ripping it again and make sure no DSP effects are adding this level increase. If it is a download, I'd email the provider and advise of the issue if that is an option.

Probably the decoder engine is breaking before it even gets into PA's processing code.

So is there a fix for me as a listener? It works with stock music player so I am guessing android media codec is capable of decoding it correctly.

Downloaded file and I got it from my friend so I myself don't have an option to contact the original provider.....
