RESAMPLING

AIght guys Everytime i resample a bassline it seems like it loses its "Push". I can't exactly elaborate on what that exactly means, but its like when you resample something does it retain all of its frequency values?

Like for instance if i have a kick hitting hi passed at 70 with some compression for added punch, and i resample it, will it still retain the same values when thrown on an empty mixer track after it has been resampled????

You could run the original and the resampled kicks through a frequency analyser and compare the peaks?

KVR have got a fair few to choose from - here



What DAW you using?

what DAW are you using? it should have a built in one...

if you bounce and import the file at the same time as the original synth, and invert the phase on one channel, they should cancel completely if exactly the same.

in theory it should bounce perfectly.

i know what you mean tho, they sometimes sound a bit 'flat' (microscopic differences, prob all in my head) when you bounce.

How much of the original frequency content is retained depends on the sample rate and bit depth that you bounce your audio at. Higher sample rates and the greater the bit depths retain more or all of the original audio signal.

You may wish to read up a little on sample rates and bit depth/word lengths.

Very briefly, to retain all of the original signal, you want to use a sample rate that is double the original. The greater the bit depth, the finer the description of the audio becomes. (non scientific answer haha) :)

yea if you're working in 24 bit then export in 24 bit not 16 bit etc
doubling it is only useful if the daw summing engine or plugins is up for the task.

you've probably already done this, but check the the output volume of your synth and/or channel volume fader before the bounce...sometimes that can effect how the bounced audio sounds. And bounce at either 24 bit or 32 bit float if possible

Scientific enough.

re-sampling implies re-encoding, which implies loss of accuracy of representation of an analog sound by a digital file, unless of course you are using a lossless codec.
