Hi guys

For quite some time I'm looking for the audio editor with good batch processing.
I checked most of the free and low price ones.

My ideal software should be able to do the following:

normalize (+dc offset correction)
trim silence and noise at the beginning and the end
fade out a small portion of sample at the end
resample (48000 to 4100)
change bit rate (32bit to 24bit)

The only one which comes close is WavePad, but because of some non-sense design decisions it's not quite there. It can do all I want, except that in batch mode, I cannot access fade out parameters and there is no resampling.

I suspect that wavelab pro could do it but I'm evaluating cheaper options first.

Thanks

Sound Forge Pro can do what you asked for but there are some caveats. You'd set up a batch job with the following:

DC Offset - Automatically detect and remove
Normalize to Peak/RMS using X %
Auto Trim using threshold

You can't use Fade Out since it fades the entire file out (same with Fade In). So you'll need to create a script like this:

asel = new SfAudioSelection(file.Length - fadesize, fadesize);
file.DoEffect("Fade Out", 0, asel, EffectOptions.EffectOnly);
file.WaitForDoneOrCancel();

I don't know what you mean by "resample" in this context.

You might also want to take a look at SoX, which is free: https://en.wikipedia.org/wiki/SoX

For the Apple platform there’s Aurchitect Myriad, which is exclusively a batch processor, and Triumph, an editor which has batch functions. In both cases, you can also script whatever you want.

seems like resonic pro (69€) can do this to (besides of many other features)

Resonic looks promising but I cannot find anything in the manual about the fade out of only a portion of a sample, and I'm unable to test it as it has no trial version available. Ahh, and I use Windows so unfortunately, Mac options aren't for me.

resonic is win only

And I don’t think Resonic has the Target Batch functions implemented as yet.

Samplitude use is on sale right now bundled with Soundforge Pro and Spectral Layers for $149

Samplitude can also do batch processing

I'm quite surprised but so far, I found Goldwave to tick most of the points.
The only serious problem with it is that it completely ignores loop points and has no editing options related to them.

I love batch processing. Dropping files or selecting folders and trimming everything below a threshold at the beginning and/or end. Using fade-in and fade-out in one step, I can remove annoying clicks. Or convert sample rate and bit depth, and maybe even add a suffix to the filename...

So I made an app for it. Just for fun. And since the web and its community have given me so much over the years, I've taken a leaf out of its book and made the app available as freeware.

Have fun with BatchTrimmer. It´s available for free via GitHub now
