How can I make all my audio files have the same volumen level? I mean, there are MP3s which are recorded way too low and others too loud, how can I make them all sound at the same level without cahnging the volume lever all the time? Thnx
Of course, 'Search' would probably have found this answer as well as many other options, but my favorite is MP3Gain.
You need to master them. If the music was already mastered to a good level but badly recorded from the original CD you could just normalise the wave but if the material was not it will need to be compressed/limited first and then normalised.
