Subject:MP3 "deadtime" Posted by: brittnell Date:9/26/2001 7:57:00 PM Does anyone know if there is a way to write an .mp3 that doesn't have that small fraction of silent space at the begining? I'm creating some loops, and want to use the .mp3 format since Acid 3.0 is now able to read it (as well as it uses less bandwidth when shared on the web). The probolem is that the original .wav files I've made are trimmed perfectly at the head and tail, but rendering them out to .mps's messes up the loop with that bit of silence it adds (why does it do that?!). It's super frustrating, and I'm hoping someone out there knows of a workaround. Thanks! Brittnell

Subject:RE: MP3 Reply by: beetlefan Date:10/2/2001 5:56:32 PM Have you considered using Windows Media Audio (.wma)?
Subject:RE: MP3 Reply by: brittnell Date:10/2/2001 7:48:30 PM Yeah, .wma has the same issues... I've since learned that it's inherent in the engine of all of these compressed audio formats. I've also tried them myself and found it to be true. Bummer... I guess I'll just have to suggest that downloaders of my loops edit them back to .wav's and trim the heads (if they want to use them in their pristine loop-state). Otherwise, .wavs just take up TOO much bandwidth over the internet to be feasible (or sound like cr@p when compressed enough to get them to .mp3 sizes). Cheers for the suggestion though.
Subject:RE: MP3 Reply by: nlamartina Date:10/3/2001 12:33:04 AM Brittnell, Another thing you could try is to compress WAV files the old fashioned way... using WinZip. Sure, it's not really comparable to MP3's, but it still gives you a pretty decent amount of compression, without the signal loss. Additionally, you could cut the sample rate in half to 22,050 kHz (assuming you're posting standard wave files), or you could make some files mono if you're sampling just one instrument. Some low-frequency samples sound pretty near their high-frequency contemporaries, depending on their content. Overall, just play around with these tools to get a real idea of how much space you're willing to sacrifice as compared to the quality. You'll find a happy medium eventually. Hope this helps, Nick LaMartina
Subject:RE: MP3 Reply by: Diesel Date:10/3/2001 8:19:41 AM I'm having the same problem with having the dead spaace before and after and mp3 loop I have made. I know however it can be done since flashkit.com provides seemless loops in mp3 format. I still hoping someone can help solve this problem for us. I have tried everything I know.
