Exporting WAV Audio is Unbearably Slow

[TheTooleMan]

After assembling video clips into a 95-minute video with synchronized 16-bit 48 kHz WAV audio, I exported the audio through Media Encoder as a single 16-bit 48 kHz WAV file using the preset in the Premiere Pro Export screen. The rendering took 15 minutes, 41 seconds. If Media Encoder or Premiere Pro had a "smart encoder" setting, the render should have taken seconds. There were no FX used in the audio.

No other resource-hogging processes were running at the time. What would impact audio rendering to such a dramatic extent?

As I found from spending time with audio folks ... audio processing can take 'bandwidth' far more than most editors think, compared to video. That might be at work here.

And yea, I don't think they have a 'smart rendering' option for audio.

I have done similar projects and did five wav-only exports yesterday. Each timeline ca 90 minutes long and i exported directly from Premiere Pro using the settings in the screen dump. It took about 5-6 seconds for each timeline. (Stereo, only internal SSD's, Windows 11)

You don´t give any details so it´s impossible to guess the reason why it happens for you.

Project Settings?

Export Settings?

OS? (Mac/PC)

Computer Specs?

The more info you can give us the better, otherwise we are effectively asking 'How long is a piece of string'.

Exporting waves should be a breeze.

Make sure your audio hardware input is set to none.

I am getting this issue. Both Premier and Media incoder are taking for ever.

Latest attempt encoder would not export a 22 minute wav file in less than an hour.

Encoder had already failed me on my video export so I shut it down went back to Premier.

Copied the audio onto it's own time line and exported my wav file in 4 minutes.

Adobe says maybe it's not a bug. If it's not a bug why did this work around work so easily?
