Hi
I have noticed that my recordings tend to have alot of high speed audio spikes. I use a PulsarII/SPF3.1c with Cubase on a PC into a mixer and run other synths 'live' via midi into the mixer. I then record a master stereo pair back into Cubase. When I look at this waveform there are massive fast spikes in it. I can't hear the spikes as I think they are to fast, but I,m wondering what overall effect they could have? And what is causing them?
Cheers

hi,

depending on the image scale of the waveform drawing, regular peaks may appear like spikes. Zoom in at the 'spike' position and see what's there.
What you describe must be hearable, or are you in a very hardcore industrial (?) then it wouldn't matter anyway :wink:

cheers, Tom

Hi
Thanks for your help. I am going to have a 'play' to see what is going on.

Hi
I had been comparing my recordings waveforms with commerially produced CDs. The commerial CDs have fewer high speed spikes. I downloaded some songs of other peoples home recordings and the few I tried had equally as many spikes as my recordings. I maybe worrying over nothing?....

Commercial productions are usually heavy compressed and maximized causing the song (and waveform) to be less dynamic (i.e. the sound level is almost constant, with no peaks and no low voulme fragments). That is why your songs look different than commercial releases.

Hi
Thanks for that, I have been using the Optimaster for mastering and found it sounds pretty good.
