Yes. The difference is generally likely to be somewhere between slight and undetectable *if the conversion is done well*. However from the POV of the audiophile engineer *any* conversion can be expected to degrade the results by losing some info. Just a question of degree. So best to avoid them if you can. That said, I was happy enough with the 48k -> 44.1k conversion done previously by the BBC. (And I did get a chance to compare with source files around the time Coyopa was launched.) So the real concern is when a conversion like this might be done 'poorly'. [1] Hence the choice by the Coyopa team to have their system do a good quality conversion rather than leave it to the tender mercy of Flash. Particularly given that even the BBC team can't look at the details because they can't see the source code used by Flash itself. They *did* try to fix this by working on their plugin, but no joy. The problem was in the Flash system as released... and which hasn't been updated for Linux. :-/ Jim [1] For some examples of how digital 'improvements' can muck up audio, have a look at http://www.audiomisc.co.uk/HFN/HealthCheck/CD.html OK, this is from Audio CDs but it shows what can go on. -- Electronics http://www.st-and.ac.uk/~www_pa/Scots_Guide/intro/electron.htm Armstrong Audio http://www.audiomisc.co.uk/Armstrong/armstrong.html Audio Misc http://www.audiomisc.co.uk/index.html _______________________________________________ get_iplayer mailing list [email protected] http://lists.infradead.org/mailman/listinfo/get_iplayer
