Peak display issue when zooming in WMA audio items

[amagalma]

Hello!

I have inserted a wma file in a project, and alt-dragged its contents so that its first transient starts at bar two.

When I zoom-in and out using the mousewheel, in some zoom levels it appears that the first transient is on bar two, but in others it appears earlier!
Have a look at the gif below to see what I mean:

It happens only with wma files. Wav files are ok.

Could you try it and see if it happens on your system tool?

Possibly all video files? Not sure.

The .wma only contains sound. Why on earth Windows uses this for its Sound Recorder application I have no idea...

Anyway, the bug is if you try to zoom in on the WMA item samples they fly all over the place visually. Playback is fine.

See this licecap. Item on left is WMA, item on right is MP3:



I hope that makes sense, you can see how the display of the WMA is scrolling around horizontally while the display of the MP3 is clearly working fine.

Can't reproduce (5.18 x64, Win8.1).

For obscure formats like WMA i would glue them to wav ASAP, personally

WMA... obscure? :O Very common file format in Windows world.

Hi,

when zooming in some item with .wma source, I got some peak display issue :



As you can see, sometimes the main peak is synch with items, sometimes it is not, but all I do is zoom/unzoom.

Thanks !

What decoder are you using?

[X-Raym]

for wma I'm not sure,

these files were encoded years ago with media encoder 9 I think ^^

But sure, glueing to wave can be a solution, that said, it is was a bit surprising as I was trying to tempo map the file.

Decoder info -> F3

I only see Decoder infos in Video options.
Is that what you are looking for (even if my media is audio only) ?
