Pi Zero Glitches when SoX Resampling - RPiZero - 04-02-2020 Hi, I just installed moodeaudio on my Raspberry Pi Zero WH and would like to give it a try. It‘s my first time using a Pi for streaming music. Before I was streaming music with my Fire TV Stick using the Tidal app. My TV is connected via Toslink to my Topping D50s DAC. I think this setup has some drawbacks in terms of SQ. That‘s the reason for experimenting with moodeaudio. I am only using Tidal for music streaming; no NAS or locally stored files on the SD card. Back to moodeaudio on my Pi Zero. I noticed some issues:

What is the CPU load with just ntive radio stream (no upsampling)? You'll probably get a good hint from running various settings of upsampling starting with no upsampling for what you can do with an RPi Zero. RPi Zero is good for suitable functions tuned to its range of features (and limitations)... I had one Zero W on a music playing duty with a cheap HAT DAC running, of couse, MoOde in the kitchen (plus a cheap digital amp made with cheap Chinese boards, laptop AC adapters and re-purposed speakers, all in one enclosure). Kitchen refitting ordered by the the Better Half and the MoOde outfit has landed in the garage and the RPi back into the drawer). RE: Pi Zero Glitches when SoX Resampling - vinnn - 04-03-2020 Yeah the Pi Zero's single core cpu doesn't have a lot of resources to play with, you're going to have to keep resampling disabled.

Thank you. RE: Pi Zero Glitches when SoX Resampling - Daciac - 04-09-2020 I would not blame the Pi Zero for this What kind of source do you use for up sampling? Using a Pi Zero (w) with a PCM5122 DAC (PIFI) it does not have issues up to sources [16 bit, 44.1 kHz, Stereo]. Above it might not make sense (if up scaling makes sense at all is a different story). The settings in Moode are for SoX: 32/384 with high quality. The "top" command reveals <50% CPU for the mpd, which leaves still some headroom. I cannot hear glitches. Without SoX diabled, mpd shows about 10% CPU Meaning, before you invest in a Raspberry 4, you might want to check your setup. The Pi Zero actually performs very well with Moode.

Are you able to stream Spotify and run 10 bands PEQ on the zero? |
