when talkgin to pro ppl or music stores or RD departements, every one says that latency isnt a problem at all and that i am crazy; I can agree with the last point but I really want to know why no one else has latency problems.
Running an esi juli@ at 48 bytes buffersize gives me an input latency of 1,05 ms at 44.1 khz which doesnt seem much, but as far as i know this value has to be doubled when for example recording and monitoring analog signals in real time..
this theoretically works for me but recording percussive instruments like bass guitar for example doesnt get me in the groove with latency, so I do mix some unprocessed signal to the monitor to get fast signals...of course I can record with latency but if the bass line should be really groovy and tight too, i need something close to zero latency..
again , every one else is tellin me that i am crazy and that latency in a scientific way is everywhere: in the air ( acoustic sonar waves), in the cables, in the DACS and even a cpu has a latency, like any other hard or software interface,too, which must be buffered to compensate bottle neck problems.
best latency performance was with windows xp; now i had to change to Win 7 OS cause of combatibility problems and i can run the same asio buffers, but there are more spikes and crackles in the signal; I guess win 7 runs more services and therefore it doesnt perfrom as well as win xp concerning latency; i am not sure right now if switching to win 7 was th right decission; also harddiscs here are making strange noises; maybe that is the new win7 experience...

I don't experience any latency problems (except when I use plugins that introduce latency, like adaptive limiter or linear phase EQ, etc).
I use mac and logic with Apogee Duet sound card.

I'm sorry I can't help you more specifically

Are you having latency on your monitors? Are they hooked up directly to your computer, or though your DAW or Mixer? What software are you using? You have to ask yourself all of those questions.

I'm using FL Studio 9, i know that program backwards, so i'm comfortable with it. and speaking of ASIO when you are recording drums just bring down the samples to 256 or until it's as low as it goes, but with no clicks, cracks, or pops.

The human ear is only capable to hear 2 ms differences of soundwaves in a room. If you have problems recording your Bass, get a monitoring solution and listen to the pure signal during recording and your playback drumtrack, afterwards move your recording ahead in time.

Delays are not perceived less than 35ms. Even then not really noticeable until around 43ms. Get a guitar interface with direct monitoring like NI Guitar Rig foot pedal or the Ik multimedia, or the line6 versions.
Why the hell are you allowing indexing to happen on an audio pc anyway?
You need to investigate how to setup a pc for audio before you try anything else. Try Cakewalk website.

1. Increasing sampling rate will decrease latency
2. With less than 4Gb off RAM W7 do not breathe well
3. You are right; no one knows that reported latency is actually input latency. There is also output latency.
4. Use mike for recording – you will not care anymore about this
5. W7 doesn’t require tweaking for DAW – everything just simply working

Here is my solution.
Don't monitor the sound you are recording and the already recorded material from the DAW ouputs.
You need an audio interface that can give you the monitored sound before it enters the computer.
I use Line6 audio interface (KB37) that has the Guitar and Bass plug-ins sound monitored directly from the interface ( cause they are built into the interface) mixed with the recorded tracks from the ouput of your DAW. = Zero latency.
I also use logic and it also compensate's all by itself for this problem, it is built into the software if you want to monitor from the DAW using any plug-ins.

Hope this helps...

hello, try to stop the not important background services and tasks from win7 system. this can help to reduce the crackles and noises. good luck.

Sound speed is approximately 340 m/s. That means - 34 cm = 1 ms latency; If your speakers are 1m from your ears, you have 3 ms latency (approx.) in that part of sound path.
We can not hear 5 ms latency as latency (as delay), we can hear it as phase-shift (for example if same signal is doubled with 5 ms latency...). But there is latency accumulation - little bit in the air, little bit in cables, little bit in CPU, audio-card, input, output etc... Don't care about numbers (I have sometimes 7 ms, in+out), trust your ears. If you hear latency, there is problem, but if you hear it, there is more then 10 ms latency accumulation...

For tweaking services try Vista Service Optimizer (fully compatible with Win7, very good software) and there is lot information about service tweaking and other tweaking on this site:

Once again! All what I done, about tweaking Windows 7, is to switch off screen saver service. I’m recording live performance with 24 channels setup on 96 KHz. Each channel has at least one plugin (Gate/compressor) plus two stereo busses for Fx. While recording I’m surfing on net, using Skype to chat, reading magazines etc. Windows 7 64 bit, 8 Gb RAM, Intel Q9650. Almost to forget the most important: Buffers in driver are at 128 and latency is 1.7 ms. What is important: You should have a good graphic interface (I’m on G Force 9600 GT 512Mb), at least 4 Gb of RAM (in my case Windows taking 3.5 for himself), good FSB -> I’m on 1600 MHz. In one word – Windows 7 is a graphical interface build for new technology comps and if you don’t fallow this better stick with W XP.
In addition, did you ask your self is it problem hardware or you. I’m working with some great musicians and no one complains about latency less than 5 ms. I tested 5 off them separately and each of them reacted when I reach 6 ms latency. “Doesn’t get me in the groove” WTF you are talking about? I think your metronome in head needs to be checked.

Hi scoobydoobypoo,

If you are really in need of 0 latency then look to faster sound cards like firewire based or pci card based. USB soundcards usually have many problems with bottle necking. I found the original MBOX to be one the best USB cards. try a sound card that has the shortest distance from the cpu. In terms of speed and throughput. USB hubs can be reset within windows. Sometimes there is a memory hangup. Sometimes you have to change which USB port is connected to the soundcard. The one closest to the cpu has the best performance. This is especially true on a laptop. If you have a bunch of other shit pluged into the USB try plugining only the soundcard in and see what happens.

If none of this works dump your current stereo mix down to a cd or a .wav player of some type. You can sync it with your soundcard if both devices have MTC. Just play the musician the track from the top and press record at the same time more or less on an empty session with no plugins active. You should get the best response this way because nothing is going on except recording.

Engineers have had to find workarounds for almost everything since gear has been available.

Hope this helps..
