how to export multi file wav without silence

Hi everybody
Use audacity by 2 years, and I thought I had now learned all.
but is not so.
Having bought a new pc with windows 10 I had to reinstall audacity.
but I have problems I never had.
I mean:
I use Audacity to create my audio CD with music mixed.
Up to last week (with windows 7, but can not remember the audacity) version could be exported to many wav files as were my songs to be mixed.
so, for example, I created me a set of wav files of several minutes each, each of which was the song to mix conm the next. So I proceeded to burn audio CDs with no pause and gap between a song and another.
But now with audacity 2.1.2 and Windows 10 I can not.
or, son-in for each song to mix a wav file span the entire cd (sum of all the tracks in the tracks) and finished the song, the remaining time remaining is with total silence.
because of the wav file is no longer being truncated at the end of the song and close to the label?
I hope that I explained with my bad English.
thank you in advance

So, you have one big WAV file? If there’s silence at the end of the WAV file (for some unknown reason) you can open that new WAV file in Audacity and trim-out the silence. Then, export the edited WAV file.

If there’s no silence at the end of the WAV file, then I’d guess there is a problem with whatever software you are using to burn the CD.

It always helps if you say exactly what version of Audacity you have. Please see the pink panel at the top of the page.

If you have multiple Audacity tracks on top of each other, and labels, then you export multiple, you may get added silence in the exported files due to a bug in Audacity 2.1.1 and 2.1.2.

This bug has already been fixed in our source code, so will be fixed in the next release of Audacity.

If this is the problem you are having, then to fix it in the Audacity version you have now, select all the tracks and do Tracks > Mix and Render before export multiple by labels.


Thank you for your reply.
go into details:
I import a song mp3 of about 3 - 4 min
I run my corrections, then a second amount mp3 song in a second track (always 3-4 minutes) by positioning it in order of time immediately preceding, but always in his second track.
and so on for subsequent tracks.
each mp3 song ever about 3 -4 minutes.
I insert track label and position it suits the label for each song.
Let me give an example.
Suppose that I have entered 3 tracks with 3 distinct tracks of 4 minutes each.
so I’ll create a 12-minute audio CD with 3 tracks mixed by four minutes each
3 wav files which unfortunately generates are:
the first with the song that lasts 4 minutes, queuing puts me eight minutes of silence,
the second begins immediately with the song and it has a tail of four minutes of silence that is the last time next track.
I repeat myself.
with windows 7 and previous audacity (can not remember the version) this does not happen.
ie: my wav file where each contained the song without gap.
so it was easy to burn the audio CD by removing the break between one song and another.
I hope I explained.
Thanks again

Please, give us your Audacity version number (all three numbers). It is in Help > About Audacity… .

It seems I already understood the problem correctly from your first explanation. The solution is therefore as I already stated: use Tracks > Mix and Render before you Export Multiple, then there will be no added silence in the exported files.


Audacity version 2.1.2

the version I had already communicated in my first post, knowing full well that it is indispensable.
anyway I repeat: Audacity 2.1.2
thanks again for everything

Sorry, it seems I did miss that. If users can put all three numbers of the Audacity version either at the top or bottom of the post it will be much easier to find in a large amount of text.



I’m sorry
it’s my fault that I have not shown the audacity version clearly.
I take this opportunity to voice my satisfaction and gratitude to all those who have helped to create such a powerful product, as efficient as audacity.
