Audacity Silences Audio At Beginning of Export

Audacity Help Forum Windows

I have an Audacity project with several tracks and each track has a Realtime Effect on it. When I export the entire project as a .wav file, the file has a long period of silence at the beginning where there should be audio.

Here are the tracks in the project: Link

Here is the resulting .wav file after export (ignore the clipping): Link

As you can see, the project and .wav files have the same length, so Audacity isn’t adding extra silence at the beginning of the .wav file, but instead it’s silencing about the first 30 seconds.

I’m using the Export Audio dialog. Sample Rate 44100 Hz, 16-bit. Export Range is Entire Project, and I’m not trimming silence before first clip. No tracks are solo’d or muted.

Can anyone help me fix this? I haven’t had this bug in Audacity before.

Edit: Exporting as FLAC or MP3 has the same issue. When I simply play the project in Audacity I can hear the first 30 seconds of audio, so there must be something going on with the Export settings.

What happens without the effect?

A bug in an effect seems more likely than a general bug in Audacity…

It looks like creating a fresh project and loading the tracks without applying the realtime effect (a reverb called Berlin Studio) will export correctly. So does this mean that this VST3 plugin is basically incompatible with Audacity exports?

Edit: Audio exports seems to work if I apply the plugin as a normal destructive effect. Kind of disappointing that I can’t currently use the realtime effect feature with this plugin, but I guess this is what I’ll have to do for now.

Edit 2: And now on a new project, trying to load the plugin as a destructive effect crashes Audacity, even after restarting the computer. Guess I’ll need to get a proper DAW where this plugin was intended to be used anyway.
