i have a few questions regasrding recording

ok i dont know if its latency or what and but when i record in mpc1000 say a 1 sec sample witch equals 44.099 round it up u get 44.1khz i assume but BUTTTT the mpc1000 startpoint is at 2.205. i didnt put that start point there, and heres the otehr thing, the wave it captured when u zoom in starts at 2.515
so what is all this dead space between 2.205-2515 and 0-2515. why does the mpc do this? is it my gear possibly how its routed? maybe the size of the cable maybe there cheap cables? help me here

ya i know its a silly question to ask, because we all cut the excess skin off. we all know how to make what sounds right and pleasing to the ear but im for real i am really curious to know about the dead space importance. anyone whos workd in goldwave and soundforge cooledit or mpc1000 have seen this but do we know why? why all this latency? how does it happen?

help a noobie out

what do you even know what the 44.1khz is? its the sample rate of your a/d converter it cant be 44.099 nor can it be 15 bit its set to the same standard as a cd. 44.1 16bit. just wanted to clear that up.

Not sure about the startpoint problem. I never noticed it and my mpc is beng sen tback to get a replacement so can't check. What do you mean by 2.205? What unit of measurement are we talking about here.

Oh and yes its possible to have a sample rate of 44099. Not all clocks come in perfectly at 44100. I had an Eventide DSP4000 and when clocked to my Creamware system it would read 44099 as well on the wordclock display page.

i know from what i read the other day that kilohertz is in the thousandth and there is 44100 cycles per sec. i tested on mpc1000 to record for 1sec and in samples it tells me the total size and it was 44.099. i did the rounding up part on my own and assumed it was 44.1khz a sec, im on a quest to learn hertz and samples thats why im asking these hilarious questions. as for 16bit besides noticeable difference between that and an 8bit can u help me understand it clearly the bones and flesh of the theorem? im down for any input. but most importantly the deadspace question above.

hmmm, i dont think the deadspace matters, it didnt seem to effect the sample at all.

But if you go to trim mode then hold the after key on the q-link and move it forward, then back, it will go to 0

alright in the mpc1000 it reads samples like this--> 000.000.000 this is from the trim page in the mpc1000. the 2.205 comes from when i sample anything the start point always is 000.002.205 (but remember i didnt add it there) and the wavform doesnt apear till 000.002.215 or in somecases 000.003.916. now theres all this deadspace of silence from 0 all the way before the wavform kicks in. remember the waform kicks in at 3.916 or 2.215 depending if its midi or cdplayer or etc time when audio starts is different everytime but the startpoint is always 2205, why 2205 when u can start at 1?

if the waveform can start at 1 it will abolish all deadspace. telling ur mpc1000 how many secs to record will have meaning agin. but ya definately help me understand what i am missing, as i said before im still learning and need input like johny five needs that white man to take him to radio shack to get crunk off battery fluid

I QUESTION THE DEADSPACE HAR HAR

nahh the sample plays fine 10secs worth of recording u can get alot of good chops out of but i think u misunderstood me. i dont wanna know how to minevour the start to its correct position cause that i know how to do. the question is why is there so much of a noticable gap, say if i did move the qlink slide for the start to 0 ull hear a pause then a quite click then the sample if i moved the start point to 2205 ull hear a lil click and then the sample.

say if i made 2205 now the new 0. so say if i cut from 0 to 2205 ull hear the sample but now when u sequence it out with a track already laid out ull notice the latency from 2205 witch is now the new 0 to the sample loop with the rest of the track ull hear it off sync.but i know how to fix it. like i said i know u as well as i love to cut the excess skin but dont talk about timestretch or using cents to correct it this is not one of those post. my question is why is there deadspace when u tell mpc to give u 1sec of record time and it gives u half of that, there is a question to be asked. ohh ya i like to add that when i resample with mainout it does the samthing.

By pad-ophiliac Sun Apr 16, 2006 7:53 pm
its supposed to do that, i remember reading somewhere in manual, quick startguide, or maybe stereoroid's page. i don't remember what the exact reason was but i think you worrying about it to much.

it's actually a lauded feature. why, i forget.

heh ok this post isnt bein taken serious, no biggy ill look into it and when i find out ill post it in here, ya its no big deal. im simply learning small things and big ones. remember a stupid question is one that hasnt been asked. ill hook up with a microtunist and ask them this. later guys

i took it seriously, i just couldn't answer you.

it has something to do with keeping a little bit of the sound you're sampling before you even hit record, i think, or before the volume spikes loud enough to hit the threshhold to trigger your record....

just so you don't miss anything i guess.

at least, this is what i THINK i remember reading.

lauded means praised

its in page52 of the mpc1000 manual where it talks about the deadspace effect, if anyone whocares can check it out. btw im reading from my manual witch is based off 1.07os. chapter 11 editing a sample. ill write back what im thinkn bout doin.
