Hi
I have a Powerbook 15" 1.67hz 512 mb ram and a 80gb 5400rpm hard drive and a Terratec Phase 24 firewire soundcard. I have installed all my software ( Logic Pro 7.01 and Kontakt 2.01 ) and started to do some recordings. I was using a loop in track 1 , a EVP 88 with a tape delay and nothing else. I recorded thru the digital ins a 24 bit stereo file coming from a 01V Yamaha digital mixer. When I started to listen to the audio files ( 15 to 20 minutes )they were good in some places and terribly bad in others with lots of crackles. Does the OSX run some kind of background application that was interfering with the recording process ? Are there any tips to fine tune OSX in a Powerbook for audio production ? Are my Powerbook specs enough for this job or do I have to buy an external disk just to record a simple 24 bit stereo file ? Thank you Alex |

Digital Sync Problems
The problem will NOT be solved by setting everything to the same clock or sampling frequency (e.g. 44100 or 48000 Hz). Even when setting everything to same NOMINAL clock frequency there will be still some slight deviations within each single piece of equipment. This is due to the design and operating temperature of your equipment. These deviations are in the range of about 0.5 to 2 Hz which means that you can still have a few clicks every minute. The best solution is to sync every piece of digital equipment from a common word clock generator. This is done in all professional audio and video facilities. In simple setups like yours you can sync the Audio Card to the incoming digital audio signal. You should be able to find that in the "extras" oder "setup" menue of your equipment and/or software. Best regards, Karl |
