Inserting silence batch style!

[Jo The Veteran]

Ok, in my car the mp3 player, that is the CRE-720 by silvercrest, or rather the speakers tend to produce the sound somewhere about 0.7 secs after the mp3 starts playing. So whatever mp3 i had it play, I'd always edit it first, by putting an 1000ms silence in the start, i used nero wave editor for that. However i just recently started working with besweet and belight and found that this program supports this in BATCH mode.

Now one problem i encountered was that the batch mode in belight doesn't... actually work all that well. If i input 2 files and encode it goes well, however more than that it displays an error, that i can't see, because it goes away really fast, and then moves on to the next file with the error again, and then the next, and the next... and it finally encodes only the last file that mysteriously doesn't bring up the error.

Still i managed to encode in batch by using the besweet command line and a bat file i made, it goes something like this. BeSweet.exe -core( -input "(Drive and folders)\(mp3name.mp3)" -output "C:\Documents and Settings\(MyUser)\Desktop\CarMP3\(Drive and folders)\(mp3name.mp3)" ) -ota( -d 1000 ) -lame( -b 128 )" ) -ota( -d 1000 ) -lame( -b 128 )
It's actually better that way because i had to pass the mp3s and their paths from winamp to belight somehow, and have no idea how to do that anyway.

However after the encode the tags of my original mp3s got obliterated. Now, i put allot of time and effort into those tags, so it's better to miss about 0.3secs from each mp3 when i hear them, than loosing the tags themselves.

So, i guess this is a thread for someone, who knows if there is a way to preserve the tags, after a besweet compression, or how to make the batch list in belight work, or how to batch silence 1000ms, in the start of many mp3s without loosing their tags with whatever program (freeware would be better), or in general why do the car speakers do that and how to fix it maybe.

My computer details are above, in the bar, still please ask whatever you think i omitted.
Thanks for your time.

Damn, this must be impossible! Who could know?

I would suggest SoundForge, a professional audio editing tool. It works very well and of of course, it's not free.

Just go to Process -> Insert Silence

Hopefully this can help you out!

Does it support batch mode though? Till now, wavepad and besweet programs that i use, erase the tags. What i'm seeking must 1.Retain original mp3 tags, 2.Insert silence, 3.Encode and 4.Do all that in batch mode for many files.
In any case i thought of a way to work around it. I imprint the tags into the mp3 filename, and then back again into tags, from the filename, using tag&rename. The drawback in this, is that i can't imprint the album image tag into the mp3 file name, so i have to loose those, and that some mp3 tags contain characters, unsupported by the file system (like # or ; ) which i loose also.
But, oh well, this is the closer i can get so i'm set with that for now.
Still if anyone knows of another way, let me know ok?
