Audacity 2.1.2, .exe not zip (I believe)
I am new to Audacity and not very technical.
I’ve completed a video edit and want to remove ambient noise. There are no pauses in the video audio, a person is always talking, but there is noticeable ambient noise I’d like to remove with Audacity.
The video clip media in question is an AVCHD video/.mts. Detail: total bitrate 12463 kbps, audio sample rate 48kHz.
From what I am experiencing, Audacity only recognizes and imports the clip file if I import via Raw Data function.
The result when playing the import in Audacity is a loud hiss. No original audio. And the what appears is a solid blue bar with no variation.
A friend suggested I need a ffmpeg library, but I have no idea what my next step is now.
Yeah, the file came from a video edit I made in EditShare’s Lightworks NLE. Now I will have to watch some Audacity tutorials to learn how to export the audio correctly from Audacity to Lightworks so it syncs up well with the video. Any hints feel free to pass along.
I exported the earlier-referenced original AVCHD video/.mts file from my video editor and imported the audio into Audacity. Of course, as a newcomer, there are varying results without knowing perfectly well why the results are what they are. Possibly, I am applying to many effects and “shooting in the dark”.
The Audacity edit exported and imported back into my video editing program does reduce the hissing background noise to an acceptable level but amplification of the interview subject in the video tapping or hitting a table, collecting CD cases together, etc., is annoying, although while in Audacity I selected these areas (only the tapping/hitting table) and reduced amplification.
One Audacity edit I performed removed the hissing to nearly a undetectable level, but the residual is a noticeable cutting in-and-out when the subject talks.
EFFECTS RECORD: Is there a menu option in Audacity I can refer to that shows all the effects and adjustments I performed in the order I made them or should I be taking notes of exactly what I do for reference and to learn?
UPLOAD AND SHARE: If I upload the orginial AVCHD video/.mts to a share site, would anyone be able to advise what would be the appropriate Audacity edit and effects actions?
WORKFLOW: Where could I find information pertaining to basic, general workflow of what Audacity effects and actions should come first and others later? For example: one YouTube video suggests for background noise reduction to follow these steps in the following order: 1. Noise Reduction 2. Normalize 3. Equalize 4. Compressor 5. Normalize (again).
Are there any official Audacity videos? (I have been referring to the Audacity manual).
Thanks for any help.
P.S., looks like Audacity imports by default the AVCHD video/.mts at 48000 for project rate.
You are advised against looking at YouTube videos about Audacity. We do not make any of those because it is currently too much work to keep them updated for each change in Audacity version. YouTube videos usually don’t say what Audacity version they are using, and some are factually wrong.
