View Full Version : Colourlike for Audio?

Anybody who uses Clouded's Colourlike kinda knows what I'm talking about.
I tried capping a TV show, but my PC crashed and I had to record the rest of the TV show from another channel. I want to merge both halves of the show together to create one show without any percieved differences. Colourlike was able to make sure that the video image looked the same. Now, unfortunatley the audio of both sources sounds different. The 1st cap has audio that is a bit louder than the 2nd cap. I've been trying to match it manually, but haven't got it exactly right.
Is there a program that can analyse 2 sources and make changes to pitch and volume levels of audio kind of like Colourlike does for video?

The corefilter Normalize ? (works for volume, pitch I don't see how you can get it different for the same show on presumably unconverted NTSC tv show)

Well it's the same show, but the channels I recorded it from are different so the audio is off a bit in pitch as well as volume.
I guess there is no way to automatically compare 2 files and attempt to match.

AviSynth's audio support isn't very advanced, and not many folks are interested in writing plugins to extend it, sadly. Dizmon was, but he's gone now. I only know how to do what you want in Soundforge and Cubase, where it's pretty simple. Maybe Audigy has something like it, dunno.

is the pitch different or just the timbre (EQing)? seems weird for pitch adjustments to be done in NTSC land, unless some channels like to make the shows faster to fit more ads in (in which case you'll have blended fields or phase shifts in one and not the other).
if it's just EQing you can play with superEQ - i believe that's inside avisynth now. but don't worry about getting them exact - it's incredibly difficult with any software, and there's just too many effects that audio can have, and very little that can be done to remove most of them (distortion for instance, jitter, echo, excessive dynamic compression, lossy artefacts, clipping, etc).

Yeah, I guess I'll give up on it.
It shouldn't make much of a difference if it's played back on a TV. The studio headphones I use probably make it sound worse than it will in a practical environment.

Can you tell me how to do that in Soundeforge?
