Don’t let the name of this topic fool you. I’ve been running into issue while making purchase of music from the artist own websites, sites like achive.org, iTune & Amazon. What’s been happening (which I just discovered) is that some sites offer .MP3 downloads while other sites offer .M4A tracks. (M4A tracks sound better than the MP3 tracks) What’s been happening is that the MP3’s would play but sound weak and low. While the M4A files would be very loud. I thought I would test something on Audacity by importing all the music files all at one time to check to “gain” levels on each track as a comparison. But I ended up getting a message saying the M4A file couldn’t be read, Unless I updated the FFmpg file, Which I did. The tracks show the veering level of sound/gain. Some off the charts while others you can barely hear.
In order to correct this, one would need to highlight/.Select the full track using the Ctrl key and your mouse. Then select “Effects” > “Loudness Normalization”. I was able to check the scale/value to -23.0 on the louder tracks and adjust the lower tracks to -13.0. What ended up happening is that both tracks ended up sounding more normal or level with the same gain without any distortion.
Just my tip for the day and I’m happy to have found this option which now allows me to listen to all my music at the same volume level.
