Uncompressing audio for editing using dbpoweramp
An unsolved problem is catnip to an engineer. Dangle a technical difficulty in front of one and the engineer will compulsively bat at it, soon becoming obsessed and delerious in their junkie-like need for a solution. (you thought it was called “fix” because the problem was solved…) I was once an engineer and a few nights ago, encountered a problem.
I’m taking a class from Jake Warga at the Hugo House. Several of the other students use minidisc recorders and those with Windows PCs were having problems editing their work because the minidisc importing tools only write files in Windows Media (WMA) format. Audacity the free editing software that many people use doesn’t read or import WMAs. So, I set off to find some free conversion apps that are easy to use. Here’s what I found:
You’ll need to download and install two things:
- dbpoweramp Music Converter - the main application
- Windows Media codec for dbpoweramp - this is the piece that knows how to decode WMA files.
- Dump all your minidisc audio somewhere on your hard disk
- Run the dbpoweramp Music converter. The first thing it’ll do is prompt you for the files to convert. Go to the directory you put all your mindisc recordings and select all of them.
- Now you’ll get the conversion dialog. Set it to convert to wave. Better yet, make it look just like this (click for full-size):
- Click the Convert button and watch it chug. When you’re done, you’ll have both WAV and WMA versions of your file:
Note those file sizes - uncompressed WAVs are usually about 10 times as big as the WMA, so keep an eye on your disk space.
