Hello
I am not an expert so my question is quite basic.
I have an old recording from my grand mother which was on a tape and is now transfered to an MP3.
When she is talking the volume level fluctuates from -45db to 0db making it very difficult to understand. It was probably an issue with the microphone.
How could it be processed to make it more understandable ?
I tried normalize and that reduces all the volume but it doesn’t boost the lowest volume.
Thanks in advance for your help
