help fixing this audio quality

Post by Interforo » Fri Dec 11, 2020 4:24 pm

Hi,
I have recorded a call with 3 people for my podcast.
Here is an extract. Can someone recommend what to do on audacity in order to improve the quality of the audio?

Note that this is the file as I get it after the recording, no edits have been made yet.
Open to your recommendations

Thanks

LevelSpeech2.ny plugin on default settings,

then desibilator.ny plugin with threshold at -10dB, (was -20dB), all other settings default.

"after" maybe needs more de-essing ?

Yes. They are specifically for Audacity & are called NYquist plugins.

In the latest version of Audacity there is a feature to install them ...
https ://manual.audacityteam.org/man/nyquist_plug_in_installer.html

After installation you still have to enable them in the plug-in manager before they appear in the effects menu.

You have to click on the "OK" button below the "Enable" button in the plugin-manager to make changes persist ...

When enabled those Nyquist plugins then should appear in the (alphabetical) effect menu as "Desibilator" & "Level Speech 2".

"Level Speech 2" makes all the people sound equally loud.
"Desibilator" reduces sibilance which can become excessive after applying "Level Speech 2".

Plugin manager should look like this ...

If the Nyquist installer has not worked, you can put copies of "LevelSpeech2.ny" & "Desibilator.ny" into this hidden folder ...

Code: Select all

C:\Users\<YourUserName>\AppData\Roaming\audacity\Plug-Ins
Then enable them in the plug-in manager.
