Hi, I'm putting together an album of my tracks, and I've made it so a lot of the songs fade into one another (some of the album is quite ambient and I didn't want to interrupt the flow of the music). However, I'll still need to decide where to place track markers for the final mix down and I'm wondering if anyone has had experience with this. Do I need to place markers at zero-crossings (is this difficult to do on a stereo file?) or can I just create infinitesimally small clip-fades either side of the split points to resolve any possible clicking issues (essentially creating my own zero-crossings)?

I know there will be no clicks when listening to the album straight through, but if the listener skips tracks I'm concerned each song may start (or end) with a click if its not at a zero-crossing. Or am I worrying too much and this won't actually happen?

I'm using Sonar for the project mixdown (to 32-bit floating, 96kHz) as I like it's compression and EQ mastering tools, plus its an easy place to manage the entire track layout. Then I use iZotope RX to resample to 44.1kHz and to add dither for the 16-bit mix. After that is where I'll decide on the track markers, I guess. Any advice is very much appreciated :-)

Track markers at zero crossings with proper x-fades quite obviously is the way to go but with your ambient one-track album if you will, its a bit more involved. I think your idea is a good one; it'll be a bit tedious to set your clip-fades large enough to be effective for your track markers, yet small enough to remain indiscernible.

One thing to realize about "snap to zero crossing" is that it does not preclude a click. Just because the sample value at that point is zero, does not mean that the slope of the line is zero. If you concatenate two pieces of audio at their "zero crossing" points you are still creating a discontinuity in the signal's slope, which can be heard in some cases. The correct way to transition between two regions is a "short crossfade". The fade will guarantee that the end of the region has near-zero level AND slope, and will sound a lot better.

Let us know how it turns out!

Thanks man, that's what I was thinking... just curious if that was how it was "supposed" to be done. Really, really, really small clip fades are the way to go, small enough not to be noticed in the music, but effective enough to stop clicks. Sweet.
