"Crackle" and "noise" on audio with a low kbps (bit rate)

LUCAS-OLIVEIRA wrote on 8/25/2022, 7:11 AM

Please, I need help!

When I try to edit some video with an audio with less than 192kbps +/- I have a glitched audio, with some "crackles" and "noises", I tried to put some plugins to correct but don't work and I don't know what to do, aways I have to convert the audio to 192kbps with another software and replace the audio track of the video with an low bit rate audio. (sorry about my english)

 

I use Vegas Pro 16, 18, 19 and 20.

I've already tried: change the project audio settings, use plugins on vegas, disable So4 Audio, update my audio driver, change my audio device.

How much lower? What is the bit rate that is lower than 192 kbps? And what is the source of this extremely low bot rate audio?

some videos with an audio like 128kbps per example, but most of the videos that's happens have 63kbps and no, it's not the sample rate the cause of the "bug" it's the bit rate, I've tested

Can we assume the audio is AAC?
Since it happens with multiple versions of VP, I would suspect a system wide playback issue. Try different media players? VLC (Video LAN) and MPC (Media Player Classic) are favored by many folks here and playback many codecs w/o issue.
Have you installed a third-party codec pack, the default ACC encoder could have been replaced by a screwed up encoder. Otherwise 64kbs is a bit low, but it should not produce nasty static. Can upload the file(s) somewhere so we may check it out it? (DropBox, GoogleDrive, OneDrive, Mega and 4Shared are few file sharing websites.

Do you by any chance have Sound Forge Audio Studio installed? The Magix 2016 low latency driver has been known to cause system-wide playback noise...it is usually described as static or screeching sound.

@LUCAS-OLIVEIRA

The sample rate of the audio is also low at 24kHz. Rewrapping to something more editable may be the best long run solution.

Look at this method.

I tried, it's not the sample rate!! The problem is de bitrate

Yep, I tried install a third-party codec pack and I have Soung Forge Audio Studio 15 Steam Edition, what can I do with it? Thank you

@LUCAS-OLIVEIRA, regarding the Magix Low Latency 2016 driver, I am not familiar with the 'Steam' version, but assuming it is the same as the version from Magix, see these instructions from Magix support:
https://www.magix.info/us/forum/audio-issue--1290482/#ca1738999
FWIW, Sound Forge Pro does not install the Low Latency 2016 driver

You may want to uninstall the third-party codec pack and reinstall VP.

btw. a 24kHz audio sample rate is abnormal for embedded audio in a video file, 48kHz is the standard.

But I mean, how can I fix the problem with sound forge? And what is VP? (again, the sample rate it's not the problem, I tested convert just the sample rate and the problem continues, I can only fix it when I convert the bitrate)

 

Thank you for the attention.

VP= Vegas Pro

I am not sure the low-latency driver (in Sound Forge) is the problem where system-wide static is a symptom. You should probably request a Vegas support ticket.

Its not, I'm still with the problem.. and Vegas suport it's a joke :/ but thanks

Vegas and Magix support in general is good, it is the convoluted support webpage to request a support ticket that is the problem. See the Vegas support instructions>
https://www.vegascreativesoftware.info/us/forum/refund--128759/#ca800814

I have a twelve-step cheat-sheet for requesting Magix support (Sound Forge and such ). It is probably similar or the same as Vegas>
