First attempt to work with version 8. I have 3 audio tracks that are wma, and one that is mp3. The volumes are not the same - mp3 much lower volume. When I look at the audio waveform on the timeline, I see substantial clipping on the wma tracks. When I right click on a track in the waveform, and adjust the volume down, to say 20%, I don't see any change in the clipped waveform being displayed. I've attached a screen copy showing the clipping. The originals of the wma files are high quality uncompressed, and I am sure are not initially clipped. I don't hear the clipping in the pte playback, but my ears are not too great. So, Is clipping really going on? If so, what is the best way to get rid of it? Also, more generally, if I have tracks with different relative volumes, what is the best way to get them adjusted appropriately? Thanks in advance for any advice.
