Title: MC 19 pauses and buffers when playing DSD 128
Post by: Valvefan on March 10, 2016, 10:12:23 am: Hi

I just got a DSD 128 album. It plays for only about 10 second then pauses to buffer. I tried buffering for 20 seconds. But no help. My PC has 4 GB of RAM.

Any suggestions?

Thanks

Any other ideas?

Post by: DJLegba on March 11, 2016, 01:37:55 pm: Do you have Play from Memory checked? (Not sure if this feature is even in MC 19, I started with MC 20). If it's there, and checked, turn it off. It doesn't work very well with large DSD files.

Post by: Awesome Donkey on March 11, 2016, 03:52:32 pm: That's a pretty low score, and that's likely why you're having issues here. It looks like the PC isn't powerful enough to handle DSD 128.

Post by: JimH on March 11, 2016, 04:06:30 pm: Definitely.

Post by: Awesome Donkey on March 11, 2016, 05:17:32 pm: DSD, especially multichannel DSD is one of the most resource intensive operations and thus requires pretty decent hardware.
Title: Re: MC 19 pauses and buffers when playing DSD 128
Post by: Valvefan on March 11, 2016, 05:25:39 pm: OK

What hardware specs are needed to run DSD 128 in 2 channel?

Also, what software can I use to down convert DSD 128 to PCM 192/24 ?

Thanks

Post by: Valvefan on March 11, 2016, 05:33:36 pm: It a PC

ASUS motherboard with Intel Atom CPU, 4GB RAM, 60GB SSD

The music files are on a NAS connected to the PC by Ethernet cable.

Post by: Valvefan on March 12, 2016, 01:57:59 am: Yes i am using MC 19
Title: Re: MC 19 pauses and buffers when playing DSD 128
Post by: Valvefan on March 12, 2016, 10:51:19 am: I used DB Poweramp to convert the DSD 128 files to AIFF 24/192 so I can now listen to my files.

I built my PC in 2010. Maybe it is time to upgrade so that DSD files can be played.

What are the minimum PC specs?

Thanks

Post by: Awesome Donkey on March 12, 2016, 04:47:22 pm: Personally for DSD (and especially multichannel DSD), I wouldn't use anything below an Intel Core-i5 processor. I'm not even sure if a Core-i3 would be up to snuff in this case.

Post by: DJLegba on March 13, 2016, 09:17:21 am: Perhaps you need a fast CPU if you're asking MC to process the DSD files and deliver them to your DAC as PCM. But to be clear, when you bitstream DSD you should be able to use any old iron. Here's my NUC i3 bitstreaming DSD256 to my exaSound DAC:

Post by: Awesome Donkey on March 13, 2016, 04:03:33 pm: A better CPU (and likely motherboard for the new CPU) for the PC would be on my list as well, IMO.
Title: Re: MC 19 pauses and buffers when playing DSD 128
Post by: DJLegba on March 13, 2016, 04:28:44 pm: If you have only a few DSD files just convert them. If you like the DSD format and intend to continue buying DSD downloads then your DAC should support DSD, in which case you're better off putting money into the DAC instead of the computer.

I really like my exaSound DAC, and never do any DSP when playing through it. However, I do let JRiver transcode to mp3 when I want to stream to my phone. If that's something you do as well you could probably do with a computer upgrade too.
