I was looking at mpTrim Pro, is it nice to do it's automatic batch trimming?

I've seen it in action, just drop and drag a directory on it, and it goes to work.

I wondered how nice it worked, and if any quality loss of the mp3 would happen as a result of this, if everything was just left on the Default settings...

But from what I saw it's not just dealing with trimming, it's looking at tags, crc, cbr/vbr, cleaning up unrecognized info, volume/maybe gain adjustment, etc...

So I'm wondering if it might mess up mp3s too?


THANKS

Can mp3val repair the inconsistency created by mp3trim?



MP3Val can do repairs, the question is, is it capable of doing a proper repair, and do I trust it? Hmmm

Here are some screenshots:

Menu shows it can repair:



Repair run on a few mp3s. (Now those show as 'Fixed'):



Scan the mp3s over. (Now these show up as Ok)



Well all I can say is, here is mptrim pro someone selling an app for like $70, and it's supposedly causing problems, and then some opensource freeware software is detecting a problem and fixing it. All I can say is typically speaking it should be the other way around, LOL...

I don't know what to think and what to trust anymore...

I used these programs and none of them found a problem except MP3-Check with Gain Volume.

Ashampoo Music Studio 3
MP3Test
MP3-Check (Says all files Gain volume insufficient, shows all of them on 0)
MP3 Checker
MP3 Shield

For some reason the default settings on mptrim Pro are messing with the gain volume, all my mp3s I used mptrim pro on erased the gain volume to 0. I put it back to default with MP3Gain, and tested again with MP3Val thinking this might of been the problem, but MP3Val still reports the same problem.

Now it seems mprtrim is creating two problems:

1. Creating a wrong number of MPEG data bytes
2. Messing up the Gain Volume


Here's MP3-Check showing all the songs now with 0 for the gain volume: (Notice all the zeros to the left of C:)

That is exactly why I was asking wink.gif

I wonder if it is mp3val that does the volume checks. Probably, it is some other utility that is used by the graphical front end you are using.

I cannot see how mp3trim could mess with gain settings, other than removing replay gain tags, or an mp3gain undo tag. That would indicate that it is changing/removing tags it does not like. Might be well possible, though.

Anyway, I am not sure whether these inconsistencies have any practical consequence that you can experience, though.

mpTrim can change the volume manually and even create fadein/outs by adjusting the global gain field of frames losslessy. I think thats one pretty cool feature of mpTrim that I haven't seen any other program do. Maybe that's the reason that it messes with this field - However, I were under the impression that gaining (such as done with MP3Gain) could not be reversed, so what does it do by changing it to 0 ???

However, besides the fact that it does not know how to properly write the Xing header, I think mpTrim is a unique product. Back when I only used mp3's, I used it to adjust the length of silence in beginning and end of my files, and it even detected analog silence pretty well. Xing header is the last problem you should think of - It can always be fixed manually (f.ex. by foobar2000).

What do you mean, what does it do by changing it to 0?

I'm saying that mptrim took out the volume gain and removed it, or set it to zero.

Ahh so mptrim doesn't know how to deal with Xing, ok...

I have foobar but it's on another computer I'm not at for the moment. Where in Foobar would you fix this?

THANKS
