Batch processing is converting to wav although NOT selected. Being dumb & tired I just assumed that was the way it was, till I got some sleep & thought about it & checked. The conversion is a Function in Batch but it is NOT selected. So, what's happening & what can I do about it? (Spent hours reconverting to mp3s!)

Hello & welcome

I don't understand.

Can you describe all the operations you did ?

- What function did you user in the batch processor ?
- On what files did you apply a batch processing ? (all wav, all mp3, wav & mp3 ?)

What I do is go to Tools/Batch Processor, then hit "..." to get Source and " ..." to get Destination.
Then I go down the Function list & highlight "Auto trim at -InfdB", and hit Run. That's all I've been interested in doing.
The files are ALL mp3s.
Yes, I do batch convert back to mp3.

I was going to post again tonight (I didn't get an email that anyone had answered my last post). Anyhow, I was going to post that I think there might be a bug in the program. I was doing some more trimming and I noticed that after each file came up it would say:
Extracting ok
Done!
I have a feeling that it's not trimming at all, but is instead purposely converting to wav, although as I wrote in my original post "converting to wav" is NOT selected. Perhaps "Auto trim..." in the program is mislabled.
(I've done several hundred files. You know that most don't need to be trimmed & I am hard put to say whether my files have or haven't been trimmed, although I did notice a couple of songs I was listening to, while I was busy, I did wonder about, but was too busy to stop & see).
Anyhow, what do you think?
Any many thanks again for answering.

It sounds correct.

The program outputs .wav files, this is normal. If you want to auto trim mp3 it is a two-step operations : Wavosaur decodes/trim/write the files, then you have to re-encode to mp3

don't forget that each re-encoding lower the quality.

mp3 is a "final" format, every operations should be done before encoding something to mp3.

About the auto trim : don't forget that -inf dB is absolute silence, if there is a little noise floor (even barely hearable) or a DC offset, it won't be trimmed
