I am having a problem with a particular music clip ripped from a CD. I have attached it in the hopes that someone else will try it on their PD9. The problem is at the end. On my system the waveform stops before the music (audio) ends, and then later the the end of the clip truncates the music prematurely. I would say it is a bad clip except it plays perfectly on Windows Media Player, and the waveform is perfectly in sync when I play it on Goldwave.

I now have another problem with a different clip. If I set the timeline slider at the beginning of the clip (and where the waveform starts) there is a 4-5 second delay before the audio starts. I am not sure which to believe. When I render it will the video be in sync with what the timeline shows, or what I hear? When I pull it in to WaveEditor it starts fine.

Hi JSINCO -

You're right. That's an odd one!

Your MP3 plays fine in iTunes, all the way to the end! (Duration 4:01).

It even plays correctly in my PD9 - the first MP3 that's worked for me!

BUT

in PD, it displays with the wrong duration (4:19) and NO audio waveform.

In iTunes, I converted it to WAV & imported both files for comparison.

In Audacity, both files display correctly...

*** Bottom line. Use a WAV version!

Cheers - Tony

A +1 to Tony's advice to just always use .wav files. They can vary a lot, with various sampling rates and bit depths, but MP3s vary even more - and they're more likely to not be compatible with some programs. Maybe that's a VBR (Variable Bit Rate) MP3 - those can be especially prone to playback errors.

It's not a sacrifice though - MP3s can sound very good, but they're still compressed, degraded copies of full resolution audio files like .wav files. Might as well stick with the highest quality input you can.
