Fiio M11 Pro DSD256 Works! How is MQA Handled?
Fiio M11 Pro DSD256 Works! How is MQA Handled?
Just updated and thrilled that I can upconvert to DSD256 flawlessly on my Fiio M11 Pro.
My question: i am upconverting as well as doing the PCM to DSD256 change with MQA files. Is the MQA unfolding occurring and then the result upconverted ? In other words, where does the upconvert and pcm to DSD occur in the audio chain in Neutron?

Afaik: Neutron has to decode the MQA first into PCM, this PCM is processed ( equalizer, stereo effects, whatever ), this processed PCM is converted into DSD.
Mqa on ifi nano black label
Hi all,
I have a local mqa file (in flac) and neutron correctly identifies it as mqa and plays ok.
However, my ifi dac should show a purple light for mqa but it remains white.
I have direct usb access enabled, but is neutron doing the unfolding rather than passing it to the dac?
Confused I be...
Thanks
Steve
P.s
I don't want get into all the mqa arguments, but a purple light would make me happy. I can then have a listen...

Re: Mqa on ifi nano black label
Afaik Neutron converts everything to PCM and delivers this to the DAC. With the one exception of DSD (if you so wish), you can convert PCM to DSD and deliver that to the DAC, or DSD can be transferred to the DAC as it is.
Feel free to contact neutronmp@gmail.com when in doubt.
Re: Fiio M11 Pro DSD256 Works! How is MQA Handled?
Thanks for the reply, I'm getting to the edges of my knowledge here but does that mean neutron can't just give mqa to a mqa supporting device and let it handle it?
Mqa is encoded inside a flac and then converted to pcm and then to dsd, assuming the leg bone is connected to the thigh bone... Sheesh.

Re: Fiio M11 Pro DSD256 Works! How is MQA Handled?
MQA isn't a free software, and it isn't included in Neutron's specification. So probably Neutron will treat it as FLAC :
Which means it converts the contents to PCM ( not perfectly, see above ) and processes this ( the conversion to DSD at the end is an optional one, which I generally wouldn't advise ).MQA-encoded content can be carried via any lossless file format such as FLAC or ALAC; hence, it can be played back on systems either with or without an MQA decoder. In the latter case, the resulting audio has easily identifiable high-frequency noise occupying 3 LSB bits, thus limiting playback on non-MQA devices effectively to 13 bit. MQA claims that nevertheless, the quality is higher than "normal" 48/16, because of the novel sampling and convolution processes.
What you might want to propose is for Neutron either to license MQA and poperly decode MQA and/or implement an identification and direct transfer of MQA to the DAC ( whether Neutron would have to obtain an MQA license for this I don't know ), similar to the one Neutron already has for DSD.

Ok much appreciated.
The hiby music app requires a subscription for mqa.
Think I'll just stick with flac....

Hi Brimley
For native DSD and for native MQA, if the DAC is supporting it, you always have to go BitPerfect. Which means no processing like EQ, Balance or Software Latency by NP. The required Setting is "Follow Source Frequency" and "Native DSD". Your iFi should go purple if you have the correct settings. This also shows you that you really playing BitPerfect (no processing by NP).
I tested it on the M15 and the MQA Symbol in the notification bar appears if it is BitPerfect. Otherwise it is not shown because the signal processing is removing the MQA information.
Best regards,
Marco

USB DAC support on USB OTG enabled devices
Hi, I get a Zorloo Ztella, it can play MQA on my pc and Amarra on iPhone (MQA shows purple light), but only shows red light with Neutron player on iPhone, that means Neutron player can recognize the track is FLAC but not decoding as MQA files.
May I ask how to set to make it right?
Thank you for any help you can provide.
