Adobe Media Encoder bug producing noise

[cheerful]

Adobe Media Encoder in Premiere Pro seems to have a bug that introduce clicking noise (sometimes really loud) in the compressed audio output.

Playing back in Premiere is without any noise. The PCM output is fine. Howerver, the MPEG-1 Layer-2 output contains some loud clicking noise that is not in any original sound track. With DV audio, there is very few noise. Howerver, when I mix in sound from my digital camear (8KHz, Mono) and void recorded on PC (22KHz, Mono), there are plenty of noise, almost unbearable.

Export PCM audio and then encode with TMPGEnc produces mp2 audio without any noise.

Is this a bug in adobe media encoder? Or am I doing sth wrong?

I may have a solution for you . . .

Does the noise occur when the audio is loud?

I had the same problem when making audio with the SurCode encoder. ie. AC3 export.
I got rid of the crackle noises by normalizing the audio from within Premiere.

Check the waveform of your source audio and see if it is clipping/saturated, if so try and normalize it.

Good luck.

Adobe's Media Encoder sucks the big one. Best off outputting to a lossless format and encoding in TMPGEnc since you have it. You'll have more control over it this way as well. The Adobe encoder uses the MainConcept engine which is good, but for some reason doesn't produce good results when used out of Premiere.

Normalization may or may not be needed. If you're track is peaking out than you would most certainly benefit from this.

It seems to happen randomly, regardless of the volume. But it does seem to happen most during those mono 8KHz comment audio.
