Question

HISSING AFTER EXPORT

  • April 28, 2018

So, my mix DOESN'T have any hiss, but when I export WITH ALL MY EFFECTS ON it adds a pretty distinct constant white noise throughout the song on the mp3 or wav.  My question is... does this sound like an adobe glitch or maybe my processor can't handle all the effects so it's creating noise?   Any help would be appreciated, Thanks!

      This issue is happening to me, I have read the thread and can say that I don't have many effects yet Adobe Audition Does add hiss to the exported track. Nothing complex to understand other than it adds hiss to the file when exporting. The track in the audition has no hiss, when exported the new file has hiss on any playback software, Foobar, audacity, windows media and Audition itself, it seems corrupt as if you try to remove the added hiss it seems like it adds reverb the audio clip changes dramatically, it highlights that the source audio is not good quality yet it produced it. I just want to export the clean track I can currently hear in audition.  I can confirm its a constent hiss and it a little rubbish the fact I cannot use audition because of this. My current workaround is to record the edited playback from audition. Use audtion for the tools and processing, export is broken full stop, tried all settings. Play it on audition while recording on Audacity seems to be the only way I can get a file without hiss. For music production this would be horrible luckily I am just doing a phone system but this for sure needs to be addressed, technically I can class Audition as broken since you cannot export the work you do on it. If you can help identfy what is happening that would be great, never had this happen before but now its stuck like it.

      What format and what bit rate/depth are you exporting to? Audition isn't broken - it will be something you are doing. But without the format details we can't get any further.

      The issue of hiss just started plaguing my recordings. I export to MP3 44100, 16K. This is sent via ftp to my station for airing. I do very little processing apart from editing and tacking on an intro and outro. This is the standard I've used for years without issue. Is this enough info to start me on a troulbe-shooting venture?

      I am having this same issue. Wav to Wav, 8 bit to 8-bit, 11025Hz mono.

      No matter what I do, I gain a steady hiss after export when playing on media player. I can filter it perfect, sounds perfect in Audition, I save the file, and its back. When I open the saved file, Audition then recognizes and plays the hiss again.

      Tried save, save as, export..... Not sure what I'm doing wrong.

      8-bit files have a maximum Signal to Noise ratio of about 48dB. That will always sound hissy - it's rather worse than an old cassette recorder would manage. The solution to this is to save your files at a higher bit rate. If you don't have that option, then I'm afraid you are stuck with this - it's the Laws of Physics you are up against. Simple formula - Max SNR is number of bits x 6.02dB - so 16-bit files have twice the SNR of 8 bit ones.

      The effects don't cause the hiss. I'm using Waves plugins.. Theres NO HISS on the song.. UNTIL I EXPORT

      Er, there's a bit of a non sequitur here...

      You've said "if I take most effects off, the hiss goes away" and then "The effects don't cause the hiss".

      You can't have it both ways! If you want to find out what's happening, then you have to work your way through this methodically, I'm afraid. IOW, you need to take them all off, and go on adding them one at a time until you find out which one it is that makes the change in your mix-down. Yes I realise that you don't appear to be experiencing this on playback, just the mix-down, and that this may be a bit of a pain, but I can't think of any other way of doing it.

      Also, the processor failing to handle the effects wouldn't produce noise - just a failure to complete the mix-down at all.

      And have you tried pre-rendering the FX to the tracks?

        So, just to clear it up.. My processor would not cause this?

        No chance. To generate noise in a file requires a source for the noise, and it's something that would have to be added quite specifically into the mix, not something that could be generated by an overworked processor.

        But without a whole lot more information, and probably the means for somebody to try this independently to see if they could replicate the results, I don't think we can solve this. I would have thought though, that if it was a common situation, somebody else would have complained about it before now. The only thing that's potentially 'different' between playing a mix directly from multi-track and playing a mix-down is that the stream from multi-track has to be encoded on the fly back to being an integer stream, and that isn't necessarily going to be the case with the Waveform playback - although if it's a 32-bit file, then it will be. Depending upon your pan law settings and whether you've compensated the master channel level in any way, there may be a 3dB difference in overall level, but that wouldn't create hiss.

        What sound device are you using?


        Thanks so much for the help.  I'm using a focusrite scarlett.2i2.

        What bit depth and sample rate are you using for your export? If there were problems processing the effects you would get drop outs not hiss. So you don't hear the hiss when playing back your mix live in Audition's Multitrack? Any Mixdown or Export should be exactly what hear when playing the mix.

        It does it at 16/24 & 32 bits at 44100khz.  if I take most effects off, the hiss goes away.

        What effects are you adding that seem to cause the hiss?
