exporting multiple regions from one wav to many mp3s

[olek321]

Hi, im new here. Hopefully you folks could help me. Im trying to solve that question since weeks now. Im on a big audiodigitalisation projekt for a university.

One thing we are doing after digitalisation is to mark regions on the BWF Format wav-files. Mainly to convert them to CD Tracks in certain Programs afterwards.

But on the second step these regions should also be used to convert the datastream to equivalent mp3s, mayba with al playlist. (Without going over a burned CD)

the only program i found capable of doing this is barbabach on the mac.
O.K. im on PC, hate myself for that often enough.

Any suggestions for other programs able to do that??? Mac or PC??
Is this the right forum to post that question??

Thanks a lot

ok I'll bite.

You have a wav in the timeline, and you need a bunch of mp3's of that wav. Are you using PT? If so, get your cuts where you want them by getting the select-tool blinking over where you want to cut and hit 'B' to cut them. Once split, highlight all and do a shift-apple-(sorry, 'control')-K to bring up your export dialog window. Select mp3 (if you have Digi's MP3 encoder installed) or just wav's if you don't. Then use iTunes or whatever mp3 encoder you'd like. Hope I got the intent of the post right...

Sorry, you misunderstood me.

We do have one audiodatastream for example, 1 hour long. We are not allowed to cut that stream into pieces. This would cause to many single files. ..
We do mark logical parts (like: interview ... music ... interview .... music) with a regionmarker tool in adobe audition or soundforge.
These regions are saved within the matadata of the file and are readable by programms like CD Architect. CD Architect for example is able to interpretate CD Trcks out of them.

Now we are lokkin for a software , that can do the same job with mp3. Just making multiple mp3s out of the regiondefinitions ....

Any other quotes??

Can CD Architect, Adobe Audition or Sound Forge export cue sheets? If that is possible, a player like foobar2000 could read wav/cue combination, and then export as separate files to mp3, flac or any other format that it supports.

Hi Daniel,
the aim is:there should no other files be created for that purpose. A cue list for each file would double the number of files. Also they might get lost or somethin other stupid happens. The playlist is already described in each file by the regionmarkers.

Barbabatch 3 and 4 is able to do it. Now im trying to find a solution on the windows plattform too. Mainly because all the rest of the work is done there

Im workin on PT in musicbuisness but for that job it fails, because its not able to record stereointerleaved files and its not capable of handling metatags also .... but htanks for the tip .... would be to much round the corner for me

you need to look at sound forge

i HAD A LOOK
seems to bevery interesting .... storing Regions without saving the whole file is possible ....

And the spcripts are interesting too, but it seems quite complicated to write one for my needs myself.

1 wav (BWF ) with many regions --> each region stored to a single mp3 in a certain quality .....

Any one could helP

You already got the answer! As been said already Soundforge can exactly do what you want!

But I think you should be able to make it work in PT just fine if that is what you normally use. Yes the program will convert the file to dual mono, so what? You can keep a copy of the interleaved file for other purposes. If you're not allowed to cut it up, just cut up a copy, which the dual mono file already is, don't make things more complicated then they have to be!

Make a duplicate track or new playlist in PT and cut up and rename the regions. If you just cut and don't use any additional processing, no new audiofiles are written to disk, so you don't get any extra files!!! The only thing you get is more regions in the regionslist.

Then afterward select all the regions on the track with the edits, and hit export from the regionslist menu. As been said, if the MP3 option is installed (which costs a little) you can export directly from within PT to MP3. If you don't have that option is installed you can export to WAV and then convert those WAV'S to MP3's with another program. Offcourse this will double the amount of files, but you can define a save location, so you can easily keep things organized and so that you can delete these WAV's later on if you have the MP3's.

(I would buy the MP3 option if this is something that has to be done on a regular basis.)

Keep in mind that for a good file housekeeping the PT audiotrack is more or less the edit list, this is what you have to select before exporting, don't try to organize the regions in the regionlist itself, because you'll get more regions with almost any action that you do in PT.

You see to be a PT fan for some reason,
i have about 20000 files to manage. In the working progress are some different things to do as editing of metatags, regiondefinition storable with file, conversion to mp3 in maybe 2 different qualities.

So, if you only think of exporting 20000 files from dual mono to interleaved, this is an unaccaptable amount of time rising on the horizon.

The very best an most timesaving is a solution, that is able to do all the editing , saving and meybe exporting thing in one go.

PT is always round the corner. No batchconverter or script ....
But thanx for your suggestions anyway

Olek,
if you happen to know a Perl programmer who can help you, there's an open-source library for reading BWF metadata (don't know its name, but it's used in Ardour DAW), so he could make a command line batch script to read those times and then invoke lame for each conversion. If he's good, he can make a couple of very usable scripts for you in just a couple of hours.
