Sample Rate Conversion (SRC) or EQ, which comes first?

Hello Bob
 Suppose, I have a source recorded at 48K and, I wish to perform some Eq (Plug-ins) in my Pro Tools. However, shoud I perform the EQ first and then SRC or vice versa?

Kind Regards


Hello, Alan. I strongly suggest that you stay at 48 kHz sampling and 24 bit until all of your work is done. Send it to the mastering lab at the highest sample rate and resolution possible. We will sample rate convert with the world’s best sample rate converter and dithering process, at only the last stage of the entire project, again, to get superior results.

Digital equalization, compression, limiting, and other processing always sounds better when performed at the highest sample rate and wordlength. Quantization distortion is spread over the widest bandwidth, and when you sample rate convert to the lower bandwidth, the distortion which is above 20 kHz is inaudible. Thus there is less degradation when you postpone the reductions to the last step.

Best Wishes,
