getting the encoding date of a WAV file?

[John Rofrano]

[Frederic Baumann] “In a Vegas 10 pro script, I would like to retrieve the encoding date/time of a WAV file dropped as an avent on the time line. I can’t find the API for that, however, Vegas has access to it because if I right-clic the event, go to Properties, this date appears in the BWF data section (in the General tab of the Property windows).”

Vegas is probably just using the standard Windows API’s to do that. Try something like this in your code:

using System.IO;
...
FileInfo info = new FileInfo(trackEvent.ActiveTake.MediaPath);
MessageBox.Show("Create Date: " + info.CreationTime.ToString());
If you look at the FileInfo class you can get all the other dates, sizes, etc. for the file as well.

Thank you John.

Actually I had already tried this, but it appears that this is not the date I am looking for: the CreationDate gives the data at which the file was created, which in my case is the date when the media finishes, plus a random number of seconds (I believe, depending on how busy the system is when recording).

The date I am looking for is the one when the recording actually starts, and which appears to be stored in the file, under the form of some kind of tag (browsing the web, I could see that this is part of the Broadcast Wave Format extensions to the WAV file format).

I believe I would have to grab some WAV parser code, but it would be so helpful if Vegas would expose the information through an API (since it has the information, as proven by the Property dialog box).

Yea, you are correct. If you want information that is part of the Broadcast Wave metadata, you will need a BW metadata parser for wave files. Sorry I can’t help there.

Thanks anyway!

I have found an interesting document, I am currently crunching it and testing what I understand…

By the way, I am now a happy new Vegas Pro 10 user. Scripting is great!
