Kreeep Posted May 25, 2021 Share Posted May 25, 2021 I was just wondering whether Poweramp downmixes 5.1 audio to stereo by just playing the first two channels, or whether it plays all channels, outputting as stereo. I have Poweramp on an Android headunit in my car and just wanted confirmation of this. Thanks. Quote Translate Revert translation?

andrewilley Posted May 25, 2021 Share Posted May 25, 2021 I presume it would be handled by FFMPEG. Probably a formula-based downmix, but Max could confirm. Andre Quote Translate Revert translation?

Kreeep Posted May 26, 2021 Author Share Posted May 26, 2021 Oh sweet. So, implying all channels are incorporated into the downmix via ffmpeg? If so, that saves me a lot of effort in manually downmixing myself. Quote Translate Revert translation?

Correct, the various channels are mapped to basic L and R by the ffmpeg module using an algorithm that tries to balance them out correctly. Andre Quote Translate Revert translation?
