Buzzing audio during playback only, exporting is fine.

Report · Jul 16, 2017

I'm experiencing similar symptoms as described in Ringing "buzz" noise audio in Premiere CC only, for just a single clip.

It seems to be a playback-only issue, exported media seems fine... no buzzing.

I'm playing a top-level sequence which experiences buzzing when playing a clip that is ultimately several nests deep as follows...

TopLevelSequence-->NextLevel1Sequence->NextLevel2Sequence->NextLevel3Sequence

...where...

NextLevel2Sequence

V1/A1 is NextLevel3Sequence.

A2 is a wav clip (music).

NextLevel3Sequence has within it a V1 and A1 but A1 is disabled (right-click disable clip). This means NextLevel3Sequence does not emit any audio. This means NextLevel2Sequence, despite it also having an A1, has no audio on A1 (even its A1 is enabled). Therefore, the appearance to me, symptom-wise, is that the music wav on NextLevel2Sequence A2 is playing but with buzzing.

The buzzing goes away when I drill down into the sequences and play them directly. So something about playback at a higher level in a set of nests seems connected with the issue. So far I've been ignoring it, clearing caches, restarting Premiere...I wasn't worried about it because I don't think it will show up in render. So perhaps this is a nested sequence playback issue which causes buzzing for some reason. (?)

Again this is playback only... it is always when playing a sequence higher up in a nest where audio is on a inner level nest. I would not make any assumptions that the buzzing is connected with the clip containing audio... since this seems like a playback issue, I'm suspicious the internal configuration of things is affecting final PC audio output given the particular configuration... that said, it may relate to the PCM/wave clip with music in combination with the lower nest having disabled audio... can't say but just fyi not to assume it's the music wave file clip.

Hmm... in thinking about this now... I've heard it twice, in two separate areas where music is playing on a wav adjacent to clips which have no audio either due to disablement right there in the same sequence or in an inner nest below.

I'll be watching for more info... will file a bug to pass on this info.

My experience with PP has convinced be to never go beyond one nested level. Strange things happen when you do.

You can nest Sequence A into Sequence B, but stop there. Don't nest B into C.

Extremely helpful Jim, thank you... I will keep things at two levels (the first level being "Sequence A").

Good tip.

I also hear this BUZZ! from time to time. Sometimes restarting helps. Sometimes it resolves itself. Sometimes I drag the clip shorter then longer again.
