Vegas 13 audio problem.

Hello.

I do not know if there is a bug with audio effects or not with Vegas 13 (previous and latest releases)
Searching this forum did not help me.

Adding a Volume effect to a film audio track, setting it to +5 db for example. Play my movie and check audio levels. Play again and I get another 5db increase. If I play it 4 times, I get a 20 db increase - rendering is OK.
Setting the volume to -5 db : the sound volume is reduced more and more.

Adding this Volume effect on a wav or mp3 file, there is no such problem : volume increase reacts as expected;

I did some research, found a workaround : if I want to listen a second time the audio, I right click the event and choose the subclip option. I then just get what I want with my Volume setting.

I get same problem with other audio effects, for example the equalizer will react more and more if I play and replay my project. Just choosing the subclip option and sound is Ok again.

I tried with my Asio sound card, the microsoft sound mapper. I tried resetting parameters.

I then cloned my Seven 64b Os, with my backup image, reinstalled Vegas 13 -> same problem.
I'll reinstall vegas 12 just to check.

Any idea ?

And same problem with Vegas 12.
I can also use the ignore sound effects option in the Options menu !

Could not reproduce this behavior.

I cannot think of what could be causing this.

Thank you for your help.

I found this problem ONLY appears with video files > 4GB.
When I import a video under this limit, no problem.
Media properties are the same !

Could someone check with such a big video file ?

To copy it on my computer, I used the HdWriter app, included with my Panasonic camera, otherwise, I get several 3.9 gb files on my sd card, and I can see 3D on the 1st one only. So with this HdWriter app, I can get a single video file ... with 3D

I also found another workaround with my big files : I add and play a small audio file that contains no sound on another track !
I have to duplicate this file, (if I mute the track, the trick does not work) to the lenght of my video.

More info : my video file is a 5.3 gb file, m2ts, 3D.
Keeping only 10 seconds of this video on a new project (cut - suppress) - same sound problem with audio effects !

As I have another 7 Gb file, I tried it : same problem.

I tried a 6.7 GB MPEG-2 file with AC3 audio on a 4TB NTFS formatted HD. I could not reproduce the behavior with the +5db Volume FX at the track or event level.

Have you tried Insert / Audio Envelopes / Volume. You may find a volume envelope more flexible than a global effect.

What is the audio format of the big files?

PCM? AAC?

Yes John, audio enveloppe is more flexible. But I do not know how to increase the volume with it.
I cut some parts, add this effect. Now, I can also (this is what I finally did) select the properties of the samples I want to increase and recalculate the Normalize value.

SonyPCH, the audio format was PCM. In case, I switched to Dolby AAC, but have no big files yet !

Problem is probably related to the use of HDwriter. I do not need this software if I remember pushing the on/off recording button from time to time (when possible)

I cannot mail this kind of file to Sony for investigations.

Again, thank you for your help and comments.

Post MediaInfo results for your large files, please.
This is possibly the weirdest symptom I've heard.
Also describe how you're playing/previewing the audio.

By any odd chance, does your very large file reside on a USB drive? There was once a problem with reading files from very large USB drives, it might have been audio, not sure.
