QUOTE (Metro SE @ Feb 26 2006, 02:03) QUOTE (camarao @ Feb 25 2006, 14:01) 1 - delay compensation ? It is not delay compensation. Why not connect both Digital cables and try inverting the master and slave relationship between the audio device and the Mixer? I think I'll try that. |

QUOTE (lepetitmartien @ Feb 26 2006, 04:24) And verify everyone agrees to work at the same bit/KHz (both on the yam and in the mac, in logic, in audio MIDI setup and the sound pref panel). that was the first thing I was sure to be ok. |

I think I've tried everything...I even get the same problem when recording thru the analog inputs ! That's not a digital issue, I think.
I'm completely lost and I don´t know what to do else... It's a question of luck, unfortunely. Sometimes I get good recordings, other times I get terrible ones. I'v tried to record with other software also like Ableton live and Dsp Quattro. I've changed the firewire cables. I've changed the way they connect to the Powerbook...The problem persists. Maybe I have a defevtive unit or maybe this card wasn't designed to be used with Macs. |

Let's see how long it takes to answer me.. There is one thing I've noticed: I get many times a message about a error with midi and audio sync, and that it recognizes a strange sample rate. Maybe there is something wrong about the Mac's Audio Midi settings... |

I FOUND IT !!! And it's unbelievable !
Any time my fridge starts , or my heater or a more strong lamp, there is a strange sample rate recognized ! That is why the bad recordings seemed so unpredictable. It seems the electricity is interfering with the sound card. Is there something I should do to protect my soundcard from being interfired by electricity ? This is a strange thing... |

You must be a very observant musician!!! You found the SOURCE of the noise, but it's maybe not the problem?
I know nothing about household electricity in your home country, but I know a little about unwanted analog signal (NOISE), caused by unbalanced current or electricty. When your fridge (or other "load" on your household current) starts up, it changes the household current, which has its own, essentially, analog signal. The household current becomes "unbalanced" in relationship to your home grounding system. Especially with motors or other high amp draw home appliances, this can be a problem. Somehow this imbalance is finding its way to your recording equipment? Short of hiring an electrician (not yet anyway), if you were recording OK before & this recording noise is new, did you add a new piece of equipment, or cable, or electrical power strip? Something as simple as a ground connection gone bad in a TRS cable, or jack can act as an antenna... or a component in an amp or something? Maybe you rerouted your cables to hook up new equipment and have the power and audio (digital or analog) cables laying side by side? The noise problem is very believable. You are too cool for finding & recognizing the source! Professional studios spend much time and money to eliminate noise, especially electrical noise. If you're interested in a good technical read on the subject- http://www.equitech.com/articles/enigma.html Let us know what you find & good luck.
