NDAC and Large FLAC File Help Please

Posted by: Lewy on 03 December 2012

Hi guys

 

I have an album in high resolution very large FLAC file format

 

File sizes vary from 100 to 500 MB per track

 

My Naim NDAC has the latest firmware and plays any FLAC file I throw at it

 

Unfortunately it won't play these large high resolution files

 

Any ideas guys?

 

Regards

 

Lew

What are you trying to play the file with?

USB will work beyond 24/192.  OTher than via USB you are not playing FLAC files with the Naim DAC.  Whatever is feeding the DAC is surely converting to PCM.

Hi

I use a 4GB USB stick that I know works with my NDAC


Will play any WAV or FLAC file I place on there via the front USB port on the DAC


But when I put the Pink Floyd Very Large HI RES FLAC files onto the stick it won't play them

 

I used DBPoweramp to convert the FLAC files to WAV and they won't play on DAC either


The converted WAV files play seamlessly on my PC

I don't think that the problem is the size of the file(s).  I have quite a few 100+ MB hi res files that I was able to play just fine on my Naim DAC.

What is the resolution you are trying to play?

 

DAC only supports 24-bit and I know there are 32-bit recordings out there which DAC can't play, but I don't know your recording.

The resolution is 24Bit

 

I have same resolution files that play fine

 

Can't understand why they wont play

 

When you plug USB in the files are accessed by the DAC (you can see USB light flashing)

 

All the new files play OK on PC

 

Strange one

I don't have any specific experience with this - but my general experience suggest its something to do with the USB stick and the way that the files are copied onto them.  Read/Write errors are fairly common  with large files. It may be the data is fragmented on the USB stick or any other number of potential errors.  The PC can deal with this by copying it into some buffer (memory, hard drive, etc.) No clue how the naim dac streams from USB stick. It may also try to suck in the whole track at once rather than "streaming" it and have some size limit. Worth contacting them.

Hello Lew,

 

I've also noticed this. Through my Squeezebox Touch (SBT) into the DAC, large flac files simply won't play. I was going to try a USB stick into the DAC but from what you are saying, this won't work either. The file will play on my computer without any problem.

 

I haven't had time to troubleshoot this yet. It might be a size limitation issue. Usually the SBT will play anything I throw at it but not this. 

 

Interesting...

Fully re-format the stick, then just copy one file onto it and try that.

 

If you downsample the files to a lower bit-rate and resolution, do they then play from USB?
