wargnerm Posted June 4, 2016 Share Posted June 4, 2016 Most of my music files have 44.1khz, 48khz and mostly 96khz sample rates. Is it a good choice to have 192kHz selected on the Hi-Res output?

andrewilley Posted June 4, 2016 Share Posted June 4, 2016 Personally, I prefer not to upsample things unnecessarily. They can't get any better than the source provides. However not sure if they get worse. (Photographs are a another matter - scaling a photo higher than its original resolution never really improves it, it just makes the imperfections bigger).

Andre Somebody tried and seen good results from upsampling the audio files, but Pamp doesn't upsample the file itself, right? Also there is no sound when I choose 48 or 44.1kHz on the Hi-Res Output.

Filip777 Posted September 20, 2016 Share Posted September 20, 2016 On HTC 10, while using Hi-Res output 24bit/48khz, when I play a Mp3 that is 16 bit/48khz (I have a lot of these), will Poweramp still upsample it to 24 bit ? Or should I maybe put Hi-res output sample rate to 92khz?

PA will upsample (or indeed potentially downsample) everything to whatever specific output mode you have defined in Settings > Audio. There is currently no way to change output quality settings on a per-file basis. I think this may be something on the radar for the future though.

Andre So I do get 24 bit after all, great. thanks Link to comment https://forum.powerampapp.com/topic/9029-is-upsampling-a-good-idea/#findComment-36244 Share on other sites More sharing options...
theoctavist Posted September 30, 2016 Share Posted September 30, 2016 There is no advantage to upsampling...there is a lot of confusion re this subject...but Upsampling is process initiated between a discrete signal and the conversion to a continuous (analog) signal. , handled by the reconstruction filter. Now....This filter might be designed to handle a certain sampling rate so...certain sample rates might need to be upsampled..but given that reconstruction filters are doing this already...intermediary upsampling is silly. Play the files at their native rate. If you need storage space, 320kBps is indistinguishable from redbook in *every * blind properly instituted test I've ever seen.

Andre There are instances in which a DAC or filter may perform better at a given rate..but audibly? Nah. Upsampling is in its best use for things like mixing ...where there are lots of DSP/editing . but for end user? Not even worth worrying about. Redbook is more than adequate(Nyquist theorem still rings true) Link to comment https://forum.powerampapp.com/topic/9029-is-upsampling-a-good-idea/#findComment-36393 Share on other sites More sharing options...
