I've placed music from a band into a Final Cut Pro 7 timeline and adjusted levels. Everything is good sounding in FCP. But when I export it, the levels can be mercurial to the point that they change on their own. People speak and the music is hot. Not so in the timeline. This only happens to the music files where are in the 9th or 10th audio track.
I try quitting and restarting, then replacing files in FCP, and changing the levels. All sounds good. Export and the levels aren't good.
The interview audio is 48 kHz. The music was recorded in 44.1. We are mixing the audio sample rates I acknowledge. But we have no issues with other 44.1 tracks (sound FX and intro closer music). The project timeline is in 48 kHz.
The audio files are .wav, but I have other .wav files in the timeline without an issue. Namely this is the opening and closing music.
