Audio sounds blown out/distorted

[ainstushar]

If I play a movie in mpv, the audio sounds like it's distorted. It sounds like the sound is coming through blown out speakers. This same video, when played in other media players like mplayerx, sounds normal. I am not sure what kinds of logs would be helpful in this.

Try with --no-config. If it's fine then, there is something weird in your config. If it's still weird, check your systems audio settings. Also operating system and sound server would be very useful info.

It seems like softvol-max is the culprit. Default is 200, I set it for 400. I wasn't sure it would create the distorted effect. Is this is some sort of library limitation? If it is, then I think it would help out others if you guys put a disclaimer in the DOCS page with something along the lines "setting it at a higher value can distort sound..."

If this is not a bug, then feel free to close this issue. Thanks.

What you probably heard was caused by clipping caused by doubling the gain.. if this is on OS X maybe we could look into using a pure float/double audio filtering pipeline instead of the signed integer one.

For example mpv --af=format=float --softvol-max=400 <file>. Not sure if that helps.

@pigoz, float and double yield same results. Any other pipelines that you recommend I try?

There were some libswresample-related fixes recently.
