Blast of random audio white noise during preview

Kalvos wrote on 1/11/2023, 12:20 PM

Vegas 20.0 build 214, Windows 10 (latest), Focusrite Scarlett 18i8 (either via Windows sound mapper or direct).

This is not a new problem. I have searched for answers without results.

My audio is recorded as .wav 96K/24bit. When previewing audio, it plays a short bit of audio, blasts white noise, and returns to the audio. It happens no matter where the audio is started. Blasts are brief. The blasts don't appear in rendered files but are very hard on the ears when lining up audio and video. Blasts do not appear if I use the audio recorded on the camera (but that's not really decent audio).

When zoomed in a few times, the waveform is shown normally, but blasts white noise. When zooming in further, solid blocks of white noise appear (they move around). When zooming in even further, the blasts show up in more detail.

I have deleted the .sfk files so the waveforms would be rebuilt. This still happens. As I said, it happens no matter where the audio preview is started, and the blocks of white noise jump around when zooming in.

As suggested elsewhere, I deleted the old Magix 2016 low-latency driver some time ago. Just to test, I deleted all the other tracks, leaving only this one. The problem persists -- as I said, only in preview playback.

Suggestions welcome! Thank you!

Just some quick follow-up info: This problem has happened for the past few versions of Vegas and with audio files straight from the recording device (Zoom F4 or recently Zoom H3VR) or edited either in Reaper or (previously) in Adobe Audition. I don't typically use lower-quality 48K/16-bit or 44K/16-bit sources, but there's no blasting problem with in-camera audio (48K/16-bit) in the playback preview.

You are another one who has a problem with wav files in Vegas. Hopefully the guys from the team will solve this bug. The solution is convert wav to flac.

All the audio files are finally synced and this would be a huge setback on this project. Right now I'm rendering this video (the first of eight concert performances) ... and it's done. But the render -- for the first time in the past few years of using 96K/24-bit .wav in Vegas -- did include blasts of white noise wherever there was an audio cross-fade (but nowhere else). Ack. What a disaster. I have days of converting and re-syncing audio ahead.😰

The conversion to flac worked. One concert piece down, seven to go. Thanks for the advice, I hope the Vegas people will fix this issue with wav files. Having double sets of files around makes archiving a nightmare!

Whenever that happened to me, the files were on an external drive. If I moved the files to the C drive, it solved the problem. Only happens when I'm under time crunch!

Thank you for the idea, but it's not really a solution (hoping Vegas is listening!). All my work is on external drives (44TB worth of USB-3). I never put working projects on my OS drive.

The underlying issue here is Hard Drive access speed, not the filetype.

FLAC is a compressed file type which uses little storage space, whereas WAV is uncompressed. WAV is the higher quality format.

No other program (including Reaper in video mode) has this issue with 96K/24bit files. I have the drive usage graph running at all times, and transfer is effortless. Also, as I noted above, if just a single 96K/24bit WAV file is used (no video at all), Vegas fails to play it correctly -- while it can handle my typical load of 8 WAV files in 48K/24bit format. (FLAC is compressed but is completely lossless -- like ZIP but designed for audio, so no loss of quality).

Sadly, they didn't fixed this glitch with the latest update... I'm so pissed off right now!
