I don't think any sp will reduce quality when resampling unless in lofi mode


Hmm i dunno you are making another sample, which itstores at a compressed file size...you are losing something everytime. It's like mp3 vs. wav.

However, no one here really seems cares about sparkly highs or super hi-fi production so really it doesn't matter.

i seem to have assumed that the compression has a threshold of degredation where as it can not break down past a certain point seeing that is already sampled and in the compressed format.

sort of like when you save a picture with gimp as 100% JPG you can open it again and save it without losing quality.

My ears tell me that after multiple generations of resample it loses quality. I tend to not resample something more than 4 times.

But that's just me.

i resampled for about 5 years and didnt notice it, I think i noticed it more way back when I first got the 404, it wasnt from resampling it was just the sound in general that sounded weird then, It just became normal, cause I was recording to a tascam 414 mk2 at the time and it had a squeaky sound I couldnt complain to much about. Then it broke and my 404 recently broke all I got is a zoom and I dig that sound the most.

i think whats happening for me is that after some effect applications etc the volume is no longer at a "nominal" level so the final resample has a lot of that "floor noise"? i think its referred as. Basically always recording shit in as loud as possible helps. make sure that red light is flickering.

Resampling is the way to go! after a while of using the resample function, you get a better feel of what ur doing, and i have my step by step process on how to do beats. so i dont have to mess around that long, and if you do it step by step, you still can jump from your almost done project on pad12 to pad7 where your sample+kick or kick/snare/.. is located! (if your not deleting pads...) and im much faster deleting a pad after a missed resample, then starting all over when using the pattern sequencer

and who cares about soundquality?

someone did extensive research on these forums and concluded resampling does NOT reduce quality. to lazy to dig up that reference. but then again i never resample as much as 9 or 10 times so your probably right about the artifacts, which i am curious about hearing .


The quality itself doesn't degrade, it's the definition...it's aliasing. Unless you're resampling 1bit->1bit, you're losing bits of definition in the audio. It's the same reason digital/software synths get that buzzing and extra tone on high and low notes. It's not as bad as making a xerox of a xerox, but it's near the same thing. It's still legible, for the most part it looks okay, but some definition is lost by compensation of the artifacting. Like I said, it takes several generations of resampling to hear it and you have to know what you're listening for, but only 1bit sampling is truly, from what I understand, how you can resample forever with no change in definition.

To put it another way, I'll try and use storing records as an illustration point.

Say you have some crates and a stack of records you want to store. Some records or double or even triple LP releases. You have to store the records in the order they're stacked on the floor, though. So sometimes you might end up at the end of the crate with a double LP and there's only room for a single LP. You have to move that one to the next crate but the rule is, if you can't fit it in the crate you're on, you gotta throw the record out. The records in this case are the movement of the audio spectrum through time and the crates are the bitrate of the sampling. So because you have to throw that record out, you get an artifact, there's loose space in the crate, so if it was audio, it's damn close, but not perfect.

1 Bit recording using this analogy throws out the crate. The record sleeves are the crate. So if you have a double LP, it doesn't matter, it stays in it's sleeve, the bitrate. Your stack of records remains exactly how you stacked them up to begin with. Hopefully that kinda explains it.

Anyway, you can hear the resampling ish happen if your SP has SUBSONIC. Sample a tone (higher pitches work best to show this). Then resample it a couple of times. You'll start to ear extra tone in the sine wave. This is where the lineup of the bits to frequency didn't match the frequency of the waveform. This happens on all audio, but with perfect waves, it's much easier to detect. Again, the more you resample, the more these 'crate spaces' begin to show up.
