Lost of sound in both channels

Hi everyone,

I did a recording but unfortunately I finded I have missing audio in certain moments (not sure if because of bad cable or that I wrote the file in a bad HDD). Fortunately, when this happened, it did only on one side, so I don’t have any muted moments. Now the thing here is that I don’t know what’s the best way to proceed here.

I downloaded channel mixer but when I “merge” one of the sides it never feels the same as the rest of the recording (you still notice something happened) I tried adding some dbs with the amplifier but it doesn’t feel good.

I also tried converting the whole file in mono and then with the amplifier add a bit more gain to the mix and seemed to do the trick. But I just want to make sure what could be the best way to approach this.

Thanks for reading and for helping out everybody!

If it’s a speech recording, then that sounds like a good fix.

If it’s music, then I might try splitting the track (Splitting and Joining Stereo Tracks - Audacity Manual) and trying to fix the problem while retaining stereo.

Hi There!
Thanks for your reply.

It’s music… And I don’t know how splitting the track should work… This is how my entire recording looks like

In the second attachment I’m going to have issues since the audio droped at both channels, but I guess I can live with that.


Oh dear, that’s rather badly damaged.
I’d be tempted to check / replace my leads and re-record.

If it’s not possible to re-record, then:

  1. Click on the track name
  2. From the drop-down menu select “Split Stereo Track” (NOT the “to Mono” option). This will give you two mono tracks, the upper one panned all the way left and the lower one panned all the way to the right.
  3. You can now apply the Amplify effect to the quiet parts, one channel at a time.

When you have finished, Exporting will automatically mix the tracks together into a single mono track. Alternatively you can use “Make Stereo Track” from the upper track’s drop-down menu.

Steve, thanks. I’m doing it, but with amplifier it seems that it’s not possible to make it sound the same way, I get to amplify by adding some dbs but I’m getting not the best result… Do you have any tips for me here? Is there a way to “automate” the dbs to the same volume as the working channel?

Do you think channel mixer could help me out with this?

Thanks a lot

Well guys, I kind of fixed my entire recording

But I still have 2 missing parts where I don’t have any audio recorded from both sides for about 4-5 seconds each.

Since it’s electronic music and it’s in 128bpm I was thinking in copy/paste the last 4 beats and kind of reduce the muted breachs I have.

I was trying doing simple CTRL+C - CTRL+V but the beatmatching is never good.

Is there any recommendation here?
