  • How to quantize multitrack audio with audiosnap

Found lots of old posts with the same problem. No real answers in any of them.
 
I went through many videos. Mostly they read what is written on the button without explaining further. No video tackles simple quantization.
 
The manual does have a section "Why would I use it" with 7 applications, but not the most obvious, how to quantize tracks. I thought "To sync an audio clip to the project tempo would be it (3 easy steps) but it just jumbles everything into a complete mess.
 
I have 38 tracks. The drummer was excellent, but over time, naturally, he drifts off the grid. But it is just a drift. He was superbly accurate.
 
I want to quantize the drum track to the average tempo, and all other tracks also.
 
One Sonar University video says you have to take out all transients on the bass drum that are not on the beat, so I did that and only left the whole note beats.
 
Hit Quantize, set to whole notes, and audiosnap does not even do THAT right! Transients did change positions, but not on the grid.
 
Does anyone know of tutorials or videos to achieve this most obvious of audiosnap tasks?

I found a video where at one point the guy says: "Those pool markers can be used to apply tempo to another track which is known as groove matching"

I thought, GREAT! This could be it - and then he turns the page, without explaining further. AAAARGH!

You have probably already found this on your travels, but this SOS article really helped get my head around the audiosnap pool.

thanks from me, too.

I cannot find an authors name. I wonder how they managed to figure all that out.

I've had decent results by using it only on problem parts, like single measures and such.

I use another DAW for sorting out timing issues - that one has very "elastic audio warping" facilities. Till X1 gets as good as that, I wiill keep using the other DAW for audio quantizing.

What is the other DAW LJB? Thanks.

A very good find Mark. I have struggled with AudioSnap features but this seems very clear.
It covers a lot of the common errors that I made with this great, but confusing, tool.

FastBikerBoy did a good job on an A/S video too.

I'm no expert on audio snap but in my experience the key to getting results (for me) is to make sure the clip map is lined correctly to start with. If that isn't set up correctly I can't get it to work properly either. Setting that up can be a bit convoluted as well especially if the first transients aren't the first beat. You then need to start inserting transients at the start of the clip or there's all sorts of problems with it.

Have a look at the video M_Glenn_M mentioned above and see if that helps. I could always put up another one if it's something I do. I mainly use it to sort out the bass with the drums as well as the tempo extraction shown in the video.

I haven't used the quantise to the set M:B:T much because I prefer the natural drift through a song but it's certainly something I can have a go at as I understand the theory of doing it. If I have any success I'll put a video up and you can see if that helps. I may well be back to rant though.
