WMA exports mostly don't play on Windows ifmetadata added

2008-12-01T03:08:19

I'm forwarding below a user report about exported WMA files not being playable if tags are added (except for "Year", though that is not written anyway because it is not supported by FFmpeg). I only just got round to testing with ffmpeg at command line, but it looks if it might be an Audacity issue, because command line export with tags is OK. At the command line I have to force the codec to wma2 (else it defaults to mp3), and force tag passing from the metadata in the input file (I couldn't find how to write new tags). So with input.wma which contains Title and Comment tags, I do: ffmpeg -i input.wma -acodec wmav2 output.wma -map_meta_data outfile:infile Then output.wma has the correct two tags and plays fine in WMP 11, Foobar and VLC (which both report the codec as wma2). But if I import input.wma into Audacity and export it, or create a track in Audacity and export it as WMA with Title and Comment tags, neither of the three players will play it. VLC now can't see any codec details, though

Repeat selects...

Trying to clear the Release_Checklist, (and forgetting all the for and against arguments) I have committed a change that makes all the relevant audio selected after 'repeat', including original bit.

NewTime Scale Effect

Gale Andrews — 2008-11-28T04:58:36

Thanks for this, Clayton. You can certainly play with this for hours instead of getting any work done :=) Some points: * It seems you can get the same change in the "half steps" boxes and the "cents" boxes by entering different figures in them e.g. 0.5 half steps is the same as 50 cents if I've grasped it. I found this very confusing. Mightn't it be better to have integers for the half steps and then cents as now? Or save some space and just "half steps" and do away with the "cents" boxes? It should be obvious that 1.5 half steps is one half step and 50 cents. I'd rather see the space taken by an alternative "percent" calculation (as per Change Pitch) instead of these cents boxes. * Why the limitation on -/+ 50 in the cents boxes that forces you to use the half steps boxes if you want 80 cents? * As regards text, can we have "-12 to 12" instead of "-12:12"? And can we have "semitones (half-steps)" to match with Change Pitch? Semitones is I think much more common u

reported incompatible FFmpeg library on Windows2000

2008-11-22T21:04:45

A user of the 1.3.6 Unicode Beta Release on Windows 2000 has reported that the recommended FFmpeg binary: http://lame.buanzo.com.ar/ffmpeg.win32.2008.10.17.git-ddb6d09.audio-only.gpl.bin-dependencies.exe is refused as incompatible as follows: "The library you point to below, is the one I was trying to use. After receiving your e-mail I did the following: Uninstalled Audacity. Removed the library files. Re-downloaded the library from the link you provided. Re-installed audacity. Unpacked the newly downloaded library files into the audacity directory. Tried "Find Library" and got "Failed to find compatible FFmpeg libraries". Used Browse, and the selection dialog shows the file avformat-52.dll in the audacity directory. I select it, press Open, then OK, and get "Failed to find compatible FFmpeg libraries". I've confirmed he appears to be using our current release. Any reason for a Windows 2000 specific problem, and could anyone on that OS try it? Thanks Gale -------------------------------------

Computing waveform value at a pixel

Mat Mikul — 2008-11-21T19:32:28

Hello, How is the actual waveform value at a specific pixel is computed? For example, if I want to draw the waveform and show 5 points per second, I should look at the samples around each point (some function of number of samples per second and number of points per second). Now to compute the actual value, is it standard to average all the values around the point or max or min? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Normalize only works up to -24db?

Michael Chinen — 2008-11-21T05:27:41

I found this behavior a bit odd. The code in EffectNormalize::StartProcessing() explains why this is happening. NORMALIZE_DB_MIN is -240, but because mLevel is multiplied by 10, it means 24 db, not -240db. Is there a good reason or convention that says you should limit normalize at 24db? In any case, we don't notify the user of the truncation. float ratio = pow(10.0,TrapDouble(-mLevel*10, NORMALIZE_DB_MIN, NORMALIZE_DB_MAX)/200.0); ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Export from the manual wiki

Richard Ash — 2008-11-16T21:02:58

We need to resolve the issue with exporting the manual for 1.4.0 from mediawiki to other formats. For anyone who doesn't know, Dominic wrote a mediawiki -> xml -> pdf toolchain for Audacity, which is currently broken for reasons we don't really understand, probably because it can't absorb some bits of mediawiki syntax. It's written in python, and we don't have the resources to fix it in the short term. The problem of wanting to export mediawiki to other formats is not unique to Audacity, however. It essentially affects a large number of mediawiki using organisations. As a result there is now some fairly serious effort being expended towards a "proper" solution, in the form of the Collection extension. http://www.mediawiki.org/wiki/Extension:Collection This offers a way to specify a set of wiki pages which are to be exported, then render them to a number of formats, including PDF and ODF. xhtml export is supposed to be on the way (it's in the back-end libraries, although it may not work), from which simplif

F11 anyone?

Martyn Shaw — 2008-11-13T01:32:32

I've just committed a simple F11 'full screen' addition. It looks good to me on the Eee and PC so I didn't make it 'EXPERIMENTAL' or anything. Any problems with it? I'm trying to clear diffs in what I have to what 'people' have, if worthwhile.

Audacity for Daisy books

David Bailes — 2008-11-12T09:14:53

Hi, Daisy books can combine text and audio, and are useful for the print impaired. It appears that the open source daisy pipeline project is developing a script for creating daisy books using Audacity: http://daisymfc.svn.sourceforge.net/viewvc/daisymfc/trunk/dmfc/doc/scripts/AudacityToDTB.html David. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/

Preferences

Richard Ash — 2008-11-10T21:47:18

Because I've been messing with different languages recently, I've noticed that my preferences file now has toolbar settings sections for each of the toolbars for each of the languages I've tried. All of them have the common path prefix /GUI/ToolBars/, but then the names of the toolbars are translated. This seems to come from toolbars/ToolManager.cpp at line 548 where the contents of mBars is used as names for the settings. I'm not entirely clear how mBars is initialised, but I'm suspecting that it's containing the translated names. Now there may be good reasons for in containing the translated strings in some cases, but there are also other places like this one where they are keys and shouldn't be translated. I doubt the fix is terribly complicated, but I don't have time to do it tonight, so anyone else is welcome to have a go.

Bug with FFmpeg libraries on non-windows platforms

Richard Ash — 2008-11-10T21:38:16

I obviously haven't used this for a while, because it's been broken since before the 1.3.6 release. Anyhow, it should now be fixed in CVS, although I haven't yet proved it because my ffmpeg is currently broken. I got very confused because audacity wasn't trying to load ffmpeg, and so not emitting any log messages. I'm still not entirely sure why this was, I think it was because the name it was trying to load didn't exist, but there might be a log message missing somewhere that would be a good idea. Anyhow, it's working now, and should be looking for the right libavformat.so.XX file, where XX is the AVformat version. This was just one piece of code in FFmpeg.h which was #ifdefed for __WXMSW__, but then had the same string in both #ifdefs, so easy to fix.
