Maybe the 24 bit property cause the trouble. Hadn't we a similar issue with 24 bit Wave stereo?

Yes, and also with Float Processing, but his properties don't say...

Jessariah, can you upload an actual sample to Drive or Dropbox?

It's 4G file, so I'll have to wait until I move it over to my cloud.

The stereo mix I got from the same person opens fine.

Hm, file is biger than 4GB.

Edit:

No, wait, it's RF64 format...so I'm clueless again.

Good Catch @adis-a3097 !

Vegas only supports W64 afaik. You'll need to convert.

Thanks guys!

Oh, didn't know that. Thought that RF64 would go as well. Thank you, @Musicvid!

@Marco.
Small sidestep:
I recently started recording the speech sound for my films at 24 bit and 48,000 Hz with Soundforge in mono, because I read somewhere that this is supposed to be better especially in post-production.
Is this overdressed or problematic? I used to record 16 bit and 44,100 Hz in mono.
What would you advise me to do?
I don't do much post-processing anyway - as I'm not a sound person - only noise gate, a bit equalizer and compressor.
Any tips are welcome.

The best way is to mix a stereo track with identical channels. That way, compatibility with players and applications is assured.

@walter-i.
That's exactly how I tend to record voice/narration, too (even if the later output will be stereo then).

My Zoom / narration mic is an AT/Pro45 hanging less than a foot over my head (mono).

@Musicvid and @Marco.
Thank you both for the quick answer - that helps me again.

PS: @Musicvid
I use a T.Bone SC450 USB, at a distance of about 20 cm - with pop protection.

Edit:
You said the micro hangs over your head - does that mean it prevents popping and you might not need a pop shield?

I use the t. bone SC450 XLR version with an older Tascam USB soundcard.

Yes. It is such a hot mic that it was picking up traffic noise, so I tried the windscreen -- too muffled.

With the Toneboosters Barricade IV VST, I get compression, limiting, and broadcast levels, and some EQ takes out the boom for both my voice and piano. Very pleased (and so is my Zoom student) since I already had the gear.

And do you use Barricade IV VST as a plugin directly in Vegas Pro or in Soundforge, or another DAW?

It's all hooked up through Banana and the VST through Cantabile. That way I can get the processed audio to Zoom, OBS, Vegas or SoundForge without a lot of fuss. With VSTs, though, latency can be an issue when working live.

@Musicvid
Thanks for the tip, I'll take a closer look.
I recently bought Izotope RX8 Audio Elements with a few additional plugins and will see what I can do better with.
In any case, there's a lot to learn again.
Essentially, I want to make my voice sound a little more pleasant and reduce noise from my video recordings.

The Toneboosters plugins aren't technically free, but you can run them in demo mode forever.

They have evolved into sophisticated production tools, several with broadcast loudness monitoring.

Thanks for the tip - but € 39 for Barricade IV VST isn't really a price worth discussing.
But for now, I will of course test the demo version - you don't have to test a pig in a poke.

@walter-i.  Exactly the same here, but the VO track is only for the C channel in a 5.1 mix in Vegas Pro.

Unfortunately, my voice suffers from 'vocal fry' which, if I were an early 20s aged female singer would be very much in vogue in recent years. But I hate it. For me, Sound Forge Pro is brilliant for removing/reducing vocal fry with VOs (no lip-sync, only separately recorded VO) because I can clinically delete an offending single sine-wave, or use the 'interpolate' function to clean up a single sine-wave, or even better use the pencil tool to 're-draw' the sine-wave on the timeline to get rid of the jagged edges that are created by vocal fry. Time consuming: yes. Effective: yes.

Then there's the de-essing problem (my luck - having both vocal fry and sibilance). Even RX Adv is not all that good at reducing sibilance because the 'esses' are not always at exactly the same frequency. Mostly, I use Sound Forge Pro to manually reduce the 'S' volume - but its easy to sometimes over-bake that gain reduction and the result sounds a bit unnatural a few days later.

I've long used RX standard or Adv to finish VO tracks off with de-clipping (for which RX is excellent), volume levelling and so on. But then I've usually included over the years another iZotope plugin like Ozone or more recently Neutron 3 to curate that wanted VO sound.

Walter, the Toneboosters demos are FULLY FUNCTIONAL FOREVER 😎 The developer is one of the nicest guys, and he responds personally to emails.

Your VST host will save the last setting for you, so the limitation of not being able to save presets in the demo isn't worth mentioning.
