OTOH digital radio (in the UK at least) is 48k, so it seems reasonable. The Ardour resmapler (SRC) is pretty good as long as you select a decent sinc interpolation. You will loose qlauilty, but I doubt if you will hear the difference. > 2.

The choice is between sending it over SPDIF at 48k (involving a resampling stage), or over analogue (hopefully balanced) I guess? It depends on your feelings about analogue v's digital noise, personally I would go with SPDIF. The app that you use to send the audio out over shouldn't make any difference, but make sure your buffers are large. > Basically Im dealing with a lot of audio at 44KHz which has to mixed > together and the final output will be on 48Khz(DAT Tape).

I would say that a high quality sinc resampler will be the best quality. You shouldn't be able to distinguish th resampled audio from the original, but you sould experiemnt, of course. - Steve
