I downloaded some files from Linn Records.
These files have studio master quality (24 Bit/88.2 kHz).
All the information displayed at the SB is correct:
e.g. 2822 kbps, 88.200 kHz.
But the file can’t be played by the SB.
What is the problem:
The sampling rate or the bit depth?

SoundBridge doesn’t support anything beyond 16-bit/48 kHz, so if you wanted playback… Firefly would need to on-the-fly convert.10/07/2007 at 5:03 PM #11619
It seems that FireFly running on a NSLU2 doesn’t transcode/recode 88.2k files to 48k.
I think the Slug doesn’t have enough CPU-power to do this job.
Maybe someone can confirm this fact?10/07/2007 at 5:47 PM #11620
well, you can try it out with flacdec.
Or, if you can provide a public-domain/free FLAC file with that quality, Id be happy to confirm/dismiss 😉10/07/2007 at 6:40 PM #11621
Ok, it’s an easy job to provide a testfile:11/07/2007 at 8:24 PM #11622
my slug with flac v1.1.4 can decode the file fine.
But my RoKu soundbridge chokes on it.
So this is an issue for the folks at RoKu.
As a weird workaround you’d have to downsample the file to 44 / 48kHz so the soundbridge gets it. But thats definetly getting lots of aliasing, noise and would be hard on the slug.12/07/2007 at 3:43 AM #11623grommetParticipant
fizze, this is not exactly an issue “for the folks at Roku.” As I said… SoundBridge’s hardware doesn’t support anything above 16-bit/48 kHz — “as designed.” 8)12/07/2007 at 9:42 AM #11624
Yeah, its not “an issue” but it should be 😉
Point is, to make it work fireflies transcoding script, or whatever means of transcoding to use, would actually have to do resampling. Well, downshifting to 16 bit and 44.1kHz shouldnt be too tough since its an even factor. 😉
Quality will suffer, though.
