Title: Cracking noise with 48/24 flacs @ 16X NOS1usb
Post by: CoenP on March 07, 2012, 11:23:51 am
Hi Peter,

I was in the mood for some classical music and have a truckload of 48/24 FLAC files from B&W SoS. I observed a very audible and annoying haze of "tics" when playing (all) of these tracks with my normal settings (below). When the level increases the cracking haze becomes more prominent.

Throttling back to 8X AP everything sounds normal again.

Did I oversee a setting or is this some kind of bug or limitation?

Regards, Coen

Some more info: on thesetracks the clockres warning appeared. Some times with 1mssometimes with 10ms.

Nos buffersettings and other dials make no difference.

No. It most probably is something which really is wrong. But allow me to ask you a few questions by email (about your wife's name and such :swoon:)

If that would be caused / implied by the sample rate, it would be the most interesting (not meant cynical !).

These messages appear to be related to Changing the AI setting (from 16x to 8X). After two stop-and-starts no more messages appear.

Coen,

Can you be more specific ?
"AI" 16x and 8x does not exist, although you certainly can try to set it. So, what is which and when, and where do you attempt Play etc. - and exactly when does the message not appear anymore.

Thanks,
Peter

Oops late night mistake. I meant AP of course (as in my signature).

I set the slider from 16x to 8x in order to play the 24/48 files noiselessly.

Ehm, and now say it is too early ?

You were talking about messages, and I wanted to know when they stopped appearing.
Your cracking noise (by itself the subject of this topic of course) was another story.
I think.

Hi Peter,

I have the same problem with 24/88 and higher Flac's. When I set the AP slider back from 16 to 8x this solves the problem. Is there another solution for this problem?

Johan,

Report Peter of the NOS1 driver errors when playing with the 48x16 setting.

Regards, Coen

Sorry I don't know what you mean by 48x16 setting.

Sorry, I was very unclear. I just meant the 16x AP setteng where the cracking occurs.

If you start the nos driverpanel you have to select the 'errors' branch and see what has happened (or happens) during the cracking noise.

Hey Johan,

Although your problem will, to Coen, look the same as his problem back then, I don't think you have the same problem. But to know this, you must tell quite exactly when this happens. So, what you actually say is that it only happens with Hires files (and mention 88 as a base). But is this so ? or is it about 48 based files only, and already so with 24/48  ?

I hope I have been clear enough ...
Peter

Hi Peter,
Did some tests.
24/48, 24/96 & 24/192 flac give all cracks in the sound. Usb audio console gives fifo errors. Reducing from 16x to 8x no cracks in the sound and no fifo errors.
