  Zoom H6n Recording – Audio Hickups in created .WAV File

  Posted by Kevin Gusztaf on August 23, 2018 at 5:11 pm

  Hello!

  I’ve got an urgent question and maybe some of you have experienced this issue or have an solution to it.

  Recently we’ve been recording some interview stuff during a clients job with an Zoom H6n with an Rode NTG4+ and the Sennheiser G4 Wireless Lavs. While recording we couldn’t hear any issues but when we stopped the recording and played the created file back we noticed weird hickups and cracking noises in the recording. Both Tracks had this problem, the first file had this issues in the last third of the recording and the second one from the beginning to the end.

  As we realized that something went wrong we restarted and reconnected everything and the following recordings were again without an issue.

  Does somebody now what happened and maybe if its fixable? I already tried the RAW Import method mentioned around some forums using Audacity but without any luck.

  Here is the corrupted file: https://f1.creativecow.net/12667/recording-sample-zoom-h6n?uploaded=file

  Thanks in advance
  Kevin

  Hello Kevin and welcome to the Cow Audio Forum.

  Thanks for posting the audio sample.

  That sounds a lot like RF to me. Are you certain that you were listening intently and all the time? That doesn’t explain how the noise could be on both tracks at the same places.

  The glitches were on both the NTG4+ and wireless tracks at the same places? The NTG4+ was hard wired, right?

  Sound Devices has a great piece of software called Wave Agent. You might try opening and saving the problem audio in it.

  I haven’t tried testdisk, bit it looks interesting.

  Hello Ty Ford, thanks for the nice welcome words,

  my co-worker was metering the audio and he didn‘t notice that kind of issue while recording. An RF Problem sounds possible for me, we haven‘t checked if the band was already been used by some other other device, we‘ll keep an eye on this from now on.

  Right, the NTG4+ was hard wired through an XLR cable attached to the Rode Blimp on the one side and to the Zoom H6n on the other one. And yes, both audio tracks show the same glitches at the same corresponding times. The audio file we got was also much shorter than the On Camera sound recording. It seems like the recorded tracks skip some parts and therefore got shorter.

  Thanks for the tips, i‘ll try the software tomorrow in the office and i’lll get back with a status update.

  Thanks
  Kevin

  Hi Again Kevin.

  Another thought. Some systems like an SD card that’s freshly formatted for each shoot, or they get confused and misbehave. Not all SD cards are as good as others. Usually, the mfgr. lists a set of cards that are known to work.
