I'm using Cubase VST/32 r6 and sometimes while playing or recording audio I get clicks and pops. It's not all the times, for example I stop and then play again everything is gone.
My comp:
AMD Duron 900
128 RAM
M-Audio Delta 66
What can be wrong? |

it's either physical contacts - check cables' plugs, or the good old windows buffer underruns.
convert to linux :)
your card is supported

It's not the cables, and I'm not converting to Linux in the near future.
Any way to fix the buffer underruns? |

Mike, open the audio system setup (options>Audio setup>system). There are some parameters you can play with, and adjust as required:
1.Number of channels: Determines the amount of audio channels in use. The higher the value, the higher the demand for processing power and RAM.
2.Memory per channel: Determines the RAM amount for each channel (depends on the value in the previous menu, the number of channels). The higher the value, the better the performance, but bear in mind that you will need a lot of RAM (more than 128 MB) in order to determine a high value here.
3.Disk block buffer size: Determines the buffer size of the HD in reading or writing audio. The higher the value, the better the performance. The HD buffer size values have correspondent, minimum memory per channel use, so determine the values wisely.
To ensure better performance, raise the HD buffer size first. Start with 64 KB in the HD buffer size and 256 KB in the memory per channel. If the performance are poor, raise the HD buffer size to 96 KB (the memory per channel will than automatically raise to 288 KB). Try playing with those 3 parameters till you get good results.
4.File cache scheme: Determines the way Cubase handles audio files, and can affect the performance drastically:
A.Virtual tape recorder - Cubase "turns" into a tape recorder, which is good if you use long audio files in the track once.
B.Audio sequencer - Cubase acts as an assembly tool. Good if you use the same audio files over and over through out the track.
c.Virtual tape recorder/Audio sequencer - If you do some of this and some of that, this option will be good for you.
I use the last option, and the performance has greatly improved.
Good luck

If it is any help, I use 24bit and 96khz recording quality. |

maybe your harddisk can't bear the data throughput.
do u use ATA or SCSI ?

Hard Disk is ATA 100. Latency is 28ms, the largest I can get from the Delta. |

Mike, i don't know how you record, but if i were you, and had to record 24/96 -
1st thing - proper ASIO/DX setup: run ASIO Multimedia Setup and DirectX Multimedia setup, and run their tests. see that you don't have problems.
(this is all about drivers)
2nd: i would close all VSTi (turn them off) and effects during the recording.
this is because 128Mb RAM is not so much for audio, and the recording state uses RAM extensively.besides win9x Memory management sux.
3rd thingie is: do u always use CPU/HD monitor ?
(goto Panels->VST Performance), when the pops & clicks occur - does it CPU or HD how gives you hardtime ?
this way you'll see if you run off CPU or HD speed.
4th sometimes the problem is not with the PC:
if you use Amp + Monitors or Amplified Monitors ... check them - electrostatic noises sound like popps and clicks.
only in the 5th stage i'd check Cubase settings -
refer to PsyTom's message, just as for buffers - i simply move them to the limit - the maximum mem per chan and maximum block size - if you can't work like this better buy another 128M RAM (70 shek)
generally, i suggest you to spend 70 shekels
(or even more) on SDRAM.

1. Last time I ran the test it seemed fine, I'll do it again.
2. Sometimes it happens with VSTi's, sometimes without. BTW, the only VSTi I use at the moment is Waldorf Attack and no effects. This can't be too heavy...
3. Not always, CPU isn't higher than 15% and HD isn't higher than 10%. Only when click play and stop it goes around 60%, but not during playback or recording.
4. It's not this problem. The clicks appear exactly in the same place both playing and recording. What are the chances for the same exact click to appear exactly in the same spot twice? It's not electrostatic noises, trust me.
Maybe I should get another 128 RAM...
Thanks! |
