Help: Why is my audio only 1 frame?

[Kurimusu]

Hello!

In OpenToonz, I want to be able to animate with audio, however, I record the audio FIRST, then I animate it.

I tried to drag my audio into OpenToonz, but it only appears to be 1 frame.

Is there anyway to fix this?

Thanks!

When I drag/drop a .wav file into the xsheet the whole audio file plays back so I'm not able to repeat the problem here.

My first (and second guesses) don't seem to produce a solution (or set up the problem on my end) Those guesses being something in the preferences (I don't see anything that would be) and something is wrong with the audio file (I don't have access to your file).

I do note that in v1.02 although the audio does play and scrub in the xsheet I can't seem to find the audio icon to turn sound on in the ComboViewer.  

I must assume that you get one frame with any .wav that you drag/drop or import?

TOonz supports TWO formats:

1. non-compressed WAV (Microsoft) signed files at 8 and 16bit integer PCM
   
2. non-compressed AIFF (Apple) signed files at 8 and 16bit.

I have tested this, and WAV files saved as 32-bit float PCM load up as a single frame in TOonz. Not only that, but I noticed that TOonz WILL crash when you attempt to import 32-bit WAV files - after importing a 32bit WAV file, TOonz becomes confused, and no longer plays sounds when scrubbing the Xsheet. When I tried to drag a 16bit column past a 32bit single frame WAV column, TOonz crashes without exception.

In short, if you notice that your WAV files are loading up as a single frame in the Xsheet, it means it is a 32bit WAV file. Quite TOonz, and convert your 32bit WAV file to a 16bit version before proceeding.

To convert your 32bit WAV files to 16bit, any sound editor will suffice.

Here are the steps with Audacity:

1) download Audacity at http://www.audacityteam.org/ Either the full installation, or the zipped version which works straight out of its folder.

2) Start Audacity, and load up the offending WAV file.

3) Choose FILE-->EXPORT AUDIO

4) in the SAVE AS TYPE dropdown, select either WAV (Microsoft) signed 16-bit PCM or AIFF(Apple) signed 16-bit PCM.

5) save the file in your TOonz project. I have an audio subfolder where I put these things.

Done! You may have to switch the file browser to a different folder and switch back to update its contents.

Audio tracks in TOonz can be cut, pasted, dragged, trimmed, parts copied, and so on, and so forth. Scrubbing the timeline plays the sounds. Click on the column header and various options become available - for example, a volume slider. You may also suppress the audio ouput of a specific column for output and/or export.

Check out "Creating a Soundtrack" (starting from page 203) in the TOonz Harlequin manual for more information.

Herbert, is there anything you don't know =) haha. You're truly a great asset to this community. I didn't realize that OpenToonz was so flexible with audio editing (once you have it in the right format). That's a great help! Thanks again for all of your tips and fixes.
