Does adding effects cause audio clips to grow 10 fold in size?

Question:
I recorded a long guitar clip that was 55MB in size.
After adding some mild reverb, the audio clip was 720MB in size!


Is this normal?

Thanks

Hey Tom,

I don't think this should happen. From what I understand in Sonar, unless you destructively add an effect to the clip, it shouldn't change the size of it, and if you are adding reverb it may only increase the size of the file marginally (assuming the verb has a tail on it). Other than that it shouldn't effect the size of the clip. If you split the file and work on them like that it might effect the size, but I think it creates two files.

Yes I am splitting it at every measure and I added destructive reverb to it.

I will use the real time effects instead next time.
I was just so surprised when the size grew so large after adding reverb destructively.

Oh well...

;)
 
here's my guestimate:

if we assume that you are recording 24bit/48khz, then

55,000,000 / (48000 * 24) = 47.74 seconds of a mono track.

720,000,000 / (48000 * 24) = 625 seconds of a mono track or 312.5 seconds of a stereo track.

so what happened is that applying the reverb to the clips in the track produced a single stereo track rather than reverbed clips.

is your song approximately 5 minutes at 12 seconds long?
 
This *could* be the result of splitting the clips. My understanding is that unless you use "apply timming," the entire wave file is retained for each clip.

I'm not sure how this physically manifests itself - i.e., does it result in multiple wave files, or just make the original wave larger - but it could be the source of your problem. Try Apply Trimming on the clips and see what happens (but remember, you will no longer be able to slip edit the clips.
 
Thanks
I will try that when I get back from vacation.
Cheers
