Not sure I follow.2. Mixed the song in 48 - 24.
3. Mastered the song in 48-24.
4. After mastering, while bouncing I wanted the song to be in 44.1 and 16 so that I could copy it onto a cd. So changed the sample Rate to 44.1 and 16 while bouncing (PCM,MP3) with dithering algorithm 3. Now the bounced file will have 44.1 and 24 bit depth.
5. After bouncing,I imported the audio to a Project which had the sample rate 48 and bit depth 24 to check the Wave shape.. while playing it sounded so odd.
