LAME with nspsytune does it. The algorithm is simple. fs/4 High-pass filter -> check if there's big energy (of time domain) change -> if yes, use short blocks. if no, use long blocks. And, LAME4 (CVS tag "takehiro-2002_05_07-experimental") does it, too. But it uses subband filter output instead of fs/4 high-pass filter. -- Takehiro TOMINAGA // may the source be with you! _______________________________________________ mp3encoder mailing list [email protected] http://minnie.tuhs.org/mailman/listinfo/mp3encoder
