Optimize sound output on Headphone jack


Recommended Posts

The next phone I'm planning on buying is the ROG phone 8, which luckily has a headphone jack that supports hi-res audio to 32bit 384khz. I'm just waiting until it releases on the US.

I've never used Poweramp on a phone with a headphone jack, my current one is a Oneplus 8T that luckily has analog audio out of the USB port.

How do I optimize the playback on the 3.5mm jack? Can I get bit-perfect audio out of the jack?

My personal collection consists on mostly 16 to 24 bit FLACs with sample rates of 44khz, 88khz and 96khz.

Poweramp does not have an option to force Output rates to follow source content. You'd need to select a rate high enough for the highest resolution files you have, and then any lower content will be upsampled. Not all Android ROMs fully support high-res though, I don't know about your particular device.

There is a Feature Request for output-follows-source for external DACs, but that may not work for 3.5mm headphone jacks. You can vote for it here:
