It appears (amongst the other issues I have raised) that Noise Reduction tool is not working.
It simply does not reduce any noise.
I select a small section of the wave (where it shoiuld be ‘quiet’ or ‘silent’) - Effects - Noise Reduction - “Get Noise Profile”.
Then I select the entire wave, select Effects - NoiSE Reduction - leave all settings as pre-set and hit ‘ok’.
The “Applying Noise Reduction” timer appears as it shows the wave is being worked on… but when it finishes, the audio is exactly the same.
I have posted previously about other errors and I am still using the same Macbook to edit on Audacity 3.2.2
This issue is the same on all of the projects I am currently working on
Thanks. Steve said in a message to me that I possibly may be overdoing noise reduction. Noise Reduction creates bubbly metallic artefacts if applied too strongly, and that can be more irritating to listeners than a bit of hiss…
Is there a way that I can change / undo the noise reduction to return to the original state once I have saved and closed the project multiple times since using Noise reduction and other effects so that I can try the parameters 6, 6, 6?
I assume there isn’t but thought worth asking the question…
As I think you expect, there isn’t a way to do that.
Short answer: No
Some effects you will be able to hear, either because the effect itself is audible (for example: Reverb / Echo / Wahwah / …), or because the result can be measured (example: Normalize / Amplify), or because the effect is visible (example: Hard Clipping / Spectral Delete / …), or because the effect creates side effects / artefacts (example: Noise Reduction / MP3 encoding). When effects are subtle, or if there have been a lot of effects, it may be difficult or impossible to work out exactly what effects have been applied.
“Real-time” effects remain listed in the track’s effect stack, so you can see those by opening the project and looking at the effects attached to each track.
Some sound engineers keep a note book for each major project, in which they list all details about the project, including dates / times / place / equipment used / effects applied / …
When I was doing a lot of audio editing work, my workflow was to create a new folder to contain the project and everything related to that project. Included in that folder would be a text file containing my production notes / log. My “off-site backups” would be copies of the entire folder, so if the worst happened (the studio burned down / plague / war / volcano / …) the project would survive, including all source files and production notes. (This was company policy).
Do you know if the journal was human readable or usable in any way for Audacity users? I tried looking at it in an older alpha version, but it just crashed, so I was unable to find out exactly what it was supposed to be.
