Miska Posted February 5, 2017 Share Posted February 5, 2017 24. Thx. So you checked what NAA or HQPlayer reports? Because there are bunch of DACs that use XMOS implementation and those are all 32-bit. There are only few 24-bit USB interfaces, notably Resonessence Labs.

Miska Posted February 5, 2017 Share Posted February 5, 2017 The right pane in hqp says 24. It tells the source file format and output rate, but not output word length. But you could check HQPlayer.log for details on how many bits the DAC claims to have... Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

So I set the output bits to 24, and the problem persists, at the same spots. Could you get the output stream off of HQP upsampling so that I can send it to EmmLabs please? BTW, also tried lowering the volume by -3dBFS. I get muting in different places in the same file.

miguelito Posted February 9, 2017 Author Share Posted February 9, 2017 Can people give this snippet a try with other DACs? I am getting consistent muting with just this sample. This is a 24bit/192KHz file which is simply the HQPlayer-upsampled (poly-sinc, TPDF) version of the original 24bit/96KHz file: https://drive.google.com/file/d/0B5a3izile414dGNuSTBYQmhPRWs/view?usp=sharing You would have to play this bit-perfect to make it a meaningful check. If you're using HQPlayer this means setting filter and dither to "none" and volume to 0; in Audirvana or Roon this would mean turning DSP/upsampling completely off and also setting volume to max. I would appreciate it if you give this a try and let me know.

Solstice380 Posted February 9, 2017 Share Posted February 9, 2017 I tested under your stated conditions and had NO mutes, and no indication of Limited in HQP. Sorry that it may be your DAC. https://audiophilestyle.com/profile/21384-solstice380/?tab=field_core_pfield_3 Link to comment

Thank you. I tested on another DAC I have and found the same result as you. What DAC?

Sorry that it may be your DAC.I had noticed this sporadically for a while when playing electronic music with deep bass tones - think Moby's Long Ambients for example - but never really made much of it. But then I got The xx's latest album (I see you) from HDTracks in 24/96 and my DAC muted a whole bunch, repeatedly, at the same precise points - but only when the signal was upsampled to 24/192! And on top of this, it would mute at the same spots with either HQPlayer upsampling (poly-sinc-short and poly-sinc-short-mp) AND with Roon's native upsampling. I have sent the file linked above to EMM to troubleshoot. We'll see what the result is... Thx.

Sounded pretty good, too! I may have to grab that for the collection.
