premiere adds noise to audio file

When I play my audio file in Audition or VLC or Media Player, it sounds good.

But when I import it into Premiere, it comes with high-pitched noise.

- This is true from the media browser as well as any sequence.

- I tested it in mulitple projects - my working one and also an otherwise new and empty project.

- When I export it from Premiere, it sounds fine!

 

Here are the properties:

File Path: E:\FOLDER03\ZOOM0006\ZOOM0006_Tr1.WAV
Type: Waveform Audio
File Size: 57.38 MB
Source Audio Format: 96000 Hz - 24-bit - Mono
Project Audio Format: 96000 Hz - 32 bit floating point - Mono
Total Duration: 00:03:28:45312

Brilliant guess, but it didn't help.  

Many of the tracks don't have this problem.  (Again, none of them in Audition, etc).  

 

*I resaved one of the audio files as 48Hz (instead of 96).  That did the trick.

For more info: saving to 64Hz works, but 88.2Hz adds a different kind of noise.  Is 64 clearly better than 48 btw? 

 

Finally, I did try out different sequence settings, but that didn't affect anything.  

 

I suppose I've found a workaround, but I wish I knew what was going on.

It sounds like there's an issue with the audio output from Premiere. Check your audio hardware settings, try disabling any audio input.

It sounds like your problem is all the Sample Rate Converting being done here.

As a general rule of thumb, there are 2 'families' of sample rates. 44.1k and 48k

44.1 is used for CD, with 88.2 also being used along with 44.1 on SACD titles as well.

For video, however, we ought to work at 48k sample rate wherever possible because it is the usual standard for audio on video. 96k is grand indeed, but usually too high for using with film, especially if DVD is intended because of the bit rates involved. Sadly, YouTube (amongst others) have not helped the situation by allowing users to upload video with 44.1k audio.

64k is all but pointless (I cannot think of anything that uses it) and for all sample rate conversions I would highly recommend Voxengo's R8 Brain Pro.
