splice segment from another source
« on: January 21, 2008, 07:48:31 PM »
A drunkard tipped my recorder/laptop over at a Ryan Adams show and the cables were pulled out and I lost the middle of a song. I have an alternate copy from another taper, but would only like to splice that one song that was affected. What would be the best way to do this? I use Adobe Audition 3.
Also the alternate copy is 16/44.1 and mine is 24/96. Is there a way to up-sample the alternate copy's one song to 24/96 and then splice?

you can upsample but I'm not sure how the "up dither" would go.    you would upsample the same way you would downsample except raise it to 96.


as far as splicing goes a simple copy and paste works for me.  pin point a good spot on both sources, say a spike from the drums or clap etc and paste the other one in.  listen to both the start and end of the paste to make sure it's seamless.  you may have to raise/lower the gain of the splice to get the levels to match with the original.

I strongly recommend using crossfade.  A simple splice is going to be really noticeable and the "jump" will be disconcerting.  If done right, the crossfade is almost a seemless transition.  When patching alternate sources, I also try to match the levels as much as possible, and also EQ the patch material to sound as much like the main source as I can.

if done right a splice is a seemless transition that 99% of folks would never know was done unless they read the textfile.

how much time did you lose? if its significant it may be easiest to just replace the entire song

i don't believe you will gain any audible advantage to upsampling

Theoretically, you'd get less quantization error potential during the crossfade...though it is argueably not audible.  Most DAW software will require sound files within the same project to have matching sample/bit rates if being mixed together in the same project.

Just as a side note. Reaper will let you work with different bit rates, heck... even formats, simultaneously.
Yes, but what do you HEAR?

Thanks for the help. I was able to upsample the 16 bit file to 24/96 in Audacity. The 16 bit is quite a bit lower in volume, so will fool around with normalizing that part or using the volume function in Audacity.
How would you recommend I get the levels as close as possible? I intend to just replace the entire song with the alternate copy.
On a side note, I got popping noises in Adobe 3 when I listened to my new files. Never heard that before.
