OT-Help goes 1.1

Joe Pater, Chris Potts and I just released version 1.1 of OT-Help, and we figured we’d use this occasion to announce it on Phonoloblog.

If you’re already using OTHelp 1.0, upgrading will give you a somewhat smoother interface and the ability to export Praat files from every screen.

If you aren’t familiar with OT-Help, read more here.

We’re happy to get your comments and feedback, including ideas and requests for future versions, stories of how you used OT-Help in research or teaching, etc.

With technical issues of any kind, please contact Michael Becker.

OT-Help 1.1

Batch-convert wav to mp3

I found a way to convert a bunch of wav files to mp3 on Windows. Since it took me a while to find this supposedly simple thing, I though I’d share, and also ask if anybody knows how to do the same on a mac.

First, download the Windows version of LAME. You might already have it if you are using Audacity with mp3 files. The LAME folder has a dll file that Audacity uses, but also an exe file, which gives you a command-line interface.

From the command prompt, go to the LAME directory, and try something like:

FOR %X IN (sounds\\*.wav) DO lame %X

Where “sounds” is the path to the directory that has your sound files in it.

What is this good for? If you want to run a web-based questionnaire with sound files, you will find that browsers treat sound files poorly and inconsistently. The best way I know to improve the situation is to use Sound Manager 2, which puts your files inside a little flash object – but it requires your files to be in mp3 format.
