Mixdown audio issue: "Processing audio"

Hi all,

    I never seen this before but in my current project when I bounce down lets say all the drum tracks, I'm getting loads of progress bars saying "Processing audio" before I see the "mixing down audio".  There are loads of tracks so it takes ages.  This is new to me and I'm not sure what has changed.  Usual goes straight to "mixing down audio"

Anyone seen this or know what is changed?

I suspected this but Audio snap being what it is.. I find it difficult at times.  How can I ensure that I have no "Audio snap" enabled on any track clip.

I tried to select all clips and open/close audio snap but obviously it must then be enabled on something in there.

Hard when you have 80 tracks with 100's of clips...

Bouncing down is a totally different process to exporting tracks.

If the OP is indeed performing a bounce then it will take some time, which will increase in a linear fashion depending on the number of tracks beign bounced.

A quicker method is to use FILE > export (not Edit > export) as detailed by Tom above.

Most things can be done by Sonar in real time (cpu allowing) such as applying eq, fx, mixing, etc.
Small parts of the audio file are sent to a process which modifies the data according to the relevent plugin/fx/eq/gain adjustment/whatever and then output and mixed with other processes in real time.   This includes slip edits of audio, the audio file is simply played back earlier/later.

Some functions, however, are not done in real time.  Audio snap is the most obvious example.
Say you have an audio clip of a bass guitar playing a handfull of notes, but you want to move the timing of just one of those notes.  You use audio snap to move the start of the note and Sonar calculates the new audio wave form before and after the note so everything sounds smooth.
What you hear when you do the edit is a quick render at lower quality.  When you play back, you hear the quick rendered version.
When you bounce down,  either to tracks or for export/final mix or whatever you wish to call it, then Sonar first has to create a full resolution/high quality version of the edits you made.
Temporal shifting audio in this way is a very difficult and time consuming process for a computer.  There is A LOT of complex math involved.

This is the pre-processing stage you see when you do a mix/bounce.

When you say "I bounce all cips to audio" do you mean midi clips?  ie, drum machine patterns?

You could have a similar thing going on where your drum module is using lower quality samples for playback and higher quality samples for mixdown/bounce to audio.  In this case Sonar has to load the new samples and re-calculate all the clips using the new samples.

I know BFD2 does this, unless you tell it to work at max sample quality all the time, (assuming your PC can cope with the load,  mine can ).

I'm not 100% sure on this, but I seem to remember reading somewhere that Audiosnap - once enabled, is enabled for EVERY clip in your project.

Maybe, if this is the case, you enabled it by accident, and now it's there on all your clips without you realising it,

OK it was pre-coffee that I made the mistake. thank goodness that someone was paying attention!!!
Thanks for doing so. I've since corrected my post. Next time I need to have coffee first then try to help people. lol

"Processing audio" before I see the "mixing down audio".

This happens anytime you use a plugin like V-Vocal, btw.
