View Full Version : Sampling rate on squeezebox digital outputs

Hi Stuart,

yes on my system your 2 files (440 and 480) sound the same.

Following this test, I compressed one of my WAV file (that displays 44.19 on the Big Ben) to mp3 (with Lame), I then played the mp3 version on the squeezebox and... it now shows 44.11, just like your files.

I appears that the problem is specific to playing WAV files. With a frequency of 44.19 it is very likely that quite a few receivers will not manage to lock. Ideally one should really get 44.10.

Cheers,
Michel

Michel,
Those two files came from a .wav file I ripped from a CD and were
encoded with Lame. One of the files was upsampled to 48.0k, and on my
Squeezbox, it sounds slowed down. It would seem your Squeezebox is
working correctly, and mine isn't! I assume when you play both my
files, they sound the same to you? That doesn't really answer your
question - maybe others can comment on your wave files.

Stuart.
