Re: [MP3 ENCODER] wav/riff header support and preciseness of lame
Gabriel, I don't think is very complicated to add the CDex Riff-Wav code to Lame front-end, maybe later this week I have some time to implement this Albert - Original Message - From: Gabriel Bouvigne To: [EMAIL PROTECTED] Sent: Sunday, October 01, 2000 3:42 PM Subject: Re: [MP3 ENCODER] wav/riff header support and preciseness of lame >- Lame does not support outputting to a wav file with mp3 compression (a mp3 with wav header).

Don't use LAME - use CDEx with its LAME plugin: http://www.cdex.n3.net/ I think the downloadable version comes with a slightly older version of lame. For the newest version of the LAME plugin, try: http://www.chat.ru/~dkutsanov/ > - 'Preciseness' of lame: when I encode a wav file with a > length of 97 minutes and 4 seconds, the resulting mp3 is > only 97 minutes and 3 seconds.

I've found LAME to be perfectly precise - i've made AVIs with LAMEd soundtracks well over 3 hours in length in which the sountrack has maintained perfect sync with the video. Perhaps the programmes you're using to find the length of the individual files are incorrect. The only way i'd test for incorrectness would be to test with an AVI file - if the video and audio still sync after three hours, then it doesn't matter what some programme tells me - I know that it works.
