I want to repair a “bad” conference Audio recording with Audacity 2.1.0
This is a sample of 5 mn of my recording in this link:
Please, do your best to Help me… this is very important
Sounds like the audio has been corrupted. Little can be done to improve it …

If the goal is just to understand the words, you can help a tiny bit with Effect > Equalizer: Telephone preset.
You’re never going to make a theatrical presentation out of it. It’s massively damaged.
Just a note, some of that damage could be the MP3 conversions. Tiny, convenient MP3 sound files aren’t “free.” Each time you pass through another MP3 version, the honky, wine-glass voices get worse.
