mp3asm is an mpeg 1/2/2.5 audio layer 1/2/3 (cbr/vbr) frame level editor. The current textmode version allows cutting, copying, and pasting of frames while never violating the mpeg audio standard.

Well, most ppl probably prefer decoding, wav editing, reencoding, but that has consequences. Encoders use advanced filtering to create audio data thats easy to compress so that ppl can hardly tell the difference (depending on BR offcourse) and then they compress that filtered audiodata. Now filtering once from original full range unfiltered audio will provide the nicest result.

And offcourse, u dont have to waste precious cycles on the whole lengthy process.
Yes indeed, with wavediting programs u can edit right up to the millisecond, or even better. But to be honest, an 128kbps mpeg 1 layer 3file has 25 frames per second, which means u can cut right down to 40ms. If u dont mind the quality of a 128kbps file, how can u mind a few millisecs?Every subsequent filtering will result in more loss of data, because the only real difference between encoders is the filterbanks.

So when this app is up and running theres no more reason to waste a perfectly good rip cos of a few bad starting frames or a long lead out. At this point i even believe it should be possible to provide for fading in/out, i aint certain yet actually. I have no clue whatsoever on why Olli fromme halted development back in '97.Maybe cos mp3s were a rarity back then? Maybe some personal reason. I will prolly never know. What I do know is that he had an unbelievable idea and he wrote a program that did the job very well.
