Hi Guys - new member here - this looks like a great site / forum!
I've been using Garage Band and Logic Pro X for a long time - with no problems. Love them!
Last week Logic Pro X (and GarageBand) starting generating hiss(smooth static) - I know it's to be expected but this signal to noise ratio is just too low. I know amp plugins and pedals have built in hiss / air / static, to emulate the real thing(don't get me started on that!), but this is inherent hiss on tracks which are obviously amplified by any plugin. Everything I'm using is grounded, balanced, using same power outlet. In an effort to narrow down the problem - i disconnected everything - including the power cable - so using internal sound card and earphones (or MacBook speakers, makes no difference) hiss is still there. All plugins, limiters, compressors and EQ's completely removed, including on all busses and master track out - I have tried everything from different gain staging settings, recording low volume, changing Input buffer size, and a host of other settings. Obviously only occurs with input monitoring on - but the hiss is being recorded - if I bounce or export the track it's there. Fans on low, nothing. Thought it might be something that changed in my environment so I switched off all electricity at mains board - still there. Switched off blue tooth, WIFI - nothing works. The noise gate works, but the hiss is too loud even with recorded signal. tested guitar and setup outside of LPX and without using MacBook and it's perfectly clean - and I mean, crystal clean - like I'm used to. This started a few days ago, I've even taken a drive to an large empty park and with only using battery, still the hiss persists. I have no other issues that could help - i.e.: iTunes works fine, earphones / monitors / laptop speakers are not broken... seems like a piece of hardware has gone faulty in my MacBook. I have 320gb free space, 16 GB ram - so its not struggling at all - I'm actually impressed at how may tracks and plugins I can use at an input buffer size of 32 and LPX handles fine, doesn't get hot etc. No difference with 16bit / 24 bit - or changing sample size etc.
As for the sound - its not pops or crackles - and its not an electrical hum/buzz - just a constant sound of air like you hear when you put HIFI speakers up far too loud with nothing playing - except that it's too loud for my recorded signal to drown out when playing.
I'm guessing it's my hard drive, as I can hear that as fairly audible when working normally - but I've always heard it like that. It's like a gremlin snuck in overnight and removed some shielding inside my MacBook!
If anyone has any advice, no matter how far fetched, I would be so grateful, because I've tried everything and I just can't record anymore like this.
Im new here and don't see many auto signatures with gear setup (I did enter mine upon registration) but here it is in case it's not showing - MacBook Pro (late 2011) Q-core I7 - 16mb Ram - Ibanez GIO into Zoom FX pedal - into Behringer X1204USB into MacBook - Into LPX.
Thanks guys - I'm hoping against hope someone's got an answer - I wish it was ground loop problems cause that would be a lot easier to solve.
