Aurora Support Forum: mp3s or wavs

WAV WAV WAV WAV.

MP3's do work most of the time, but sooner or later it will come back and bite you. Convert ALL music files to WAV period!!!!!!!

I'm still trying to figure out the MP3 "shifting" thing. It seems to be something in videoedit.ocx. I'm going to put in a support ticket with the vendor of that control to see what they have to say about it.

I think it could just as simple as saying that MP3s are not supported. Or that they are supported, as long as the are converted.

Aurora wouldn't be able to convert it if an MP3 was selected, could it? (In the future)?

Fine. You're so smart you rig up the lights.

Go look at your C:\program files\aurora\cache Wink

PG, it already uses the file in the cache for playback, so it already is using the converted format. If you delete/update the original file then the cache rebuilds itself on the next startup of Aurora.

This was necessary because the "lossy" formats have a nasty habit of allowing "temporal distortions" during playback (which isn't desireable in our application), so Aurora needs to cache a "lossless" format copy of the file in order to preserve temporal integrity during playback (I'm starting to sound too Star Trek here I'm afraid).

MP3s are supported by Aurora. In fact, most users will never have a single problem with them (threads like this are the atypical exception). The MP3 problem lies in videoedit.ocx which is responsible for the conversion. Videoedit.ocx relies on the codecs and filter files on the system to perform the conversion. Because of this, other apps (particular video editors and DVD player software) can really mess up the process. Converting audio files probably isnt the best job for a video editing component, but it did enable us to also easily support video files, including seperate extraction of the audio from any video file for use with spectrographic analysis.

	The funniest thing that ALWAYS happened to me was that the start of the sequence was different on every single computer that I opened the sequence on. How to get your MP3s to WAVs? Audacity.

	Funny, I can remember with Spectrum when only mp3's worked, and wavs all failed on me. Just make sure the file is 16 bit, not 32 bit floating. Some users have had issues with the 32 bit floating format before.

	I think a friendly message when assigning an MP3 as the media file would be more appropriate - converting audio files should be left to products that specialize in that area.

	That's what I thought. Could it copy the cache to /audio/<file_name>.wav and update the field in the sequence?
