96-44.1 sample rate conversion

You might want to consider 88.2 so the conversion is "even math." An Me I've had do some work told me on two different high end systems he's used that the even math makes a huge difference. He told me that he'd rather have an additional conversion when he gets material at 96k or 48k.

In the future I will do everthing at 88.2 but this is for a bunch of stuff that I have already recorded.

[Drumsound]

I kinda figured. I just thought I could help you future.

Thanks.

The math is no more even from 88.2 than it is from 96. Both are first upsampled to around 15 MHz before being downsampled to 44.1k. You're M.E. is misinformed about the SRC digital signal process.

Basic SRC dsp:
step 1 - interpolation filter to least common sample rate
step 2 - digital low pass filtering
step 3 - decimation filter to destination sample rate

There are some sample rate converters that perform better with simple ratios. I've learned not to generalize because specific implementations seem to have more to to with the results than any ratios, numbers or formats. I suggest trying various sample rates with your own gear and using whatever sounds best to you. Just don't make any assumptions or, worse, choices based on somebody else who is using different gear.

I'm using 88.2 because Wavelab converts 88.2 to 44.1 much faster than 96 to 44.1. And because somebody told me about the "even math" theory, which sounds quite like logic to me.

I may be mistaken, but I believe the only means of downward converting with "simpler math" available on the audio market today is sending an SMUX adat signal to a non-smux input at half the sample rate.

I've tried the best of the hardware and software means of samplerate conversion. I've gotten the best results using a great 96k D/A (such as dCS) analog-out to a great 44.1 adc. Most mastering engineers use the same technique.
