LG V35. noise free, crisp, full 32 bit 44.1 effects chain in a termux container going straight to the DAC, android is completely out of the way now
adreno 630 GPU acceleration, audio playback via internal storage or firefox. no root required
impulse response, delay, 30 band equalizer, plenty of other effects. i use this as the DAC for my stereo setups and IEMs
source shows up as s16, but all the linux apps are showing up as float32 sources with resampler copy straight into the effects buffer
i had to fight both android and linux for this, learned a ton about how audio moving through memory and buffers can affect bass and treble quality. but the resulting audio quality was absolutely worth it. the DAC is the entire reason i bought this phone. intending to try REW room correction by using this as a source now that its all running at the same bit and sample depths, and before i was fighting buffers which messed up the clock and distortion. it wasnt audible but it was very fatiguing on the ears
