Hi! I removed the noise and it is successfully removed but after that my own voice is also disturbed and it is kind of echo. Is there any way to upload my that mp3 sound??
You don’t need to show us the sound. Effect > Noise Removal works on both the bad and the good sound. If you use very high values of noise reduction, the show will not sound good.
Go back to the original show (you saved it as a WAV, right? Audacity is not good editing MP3.) and do Noise Removal again but this time pick much lower reduction numbers like 6dB or 9dB.
Some people try to rescue a very bad and noisy show with Noise Removal and have the problem you do. If you can’t hit a good balance between getting rid of noise and voice damage, you may need to shoot the work again.
