- 0. ./configure script
- things to check for:
- -llibsndfile (allow user to enable)
- -lncurses
- -lGTK (allow user to disable)
- make depend option for CC
- 1. Modularization:
- BladeEnc.dll was written before lame was 'modularized'
- this should be cleaned up to look like main.c: It should be possible
- to write the BladeEnc/lame dll so that it just uses
- #include "lame.h" and then calls to various lame_*() routines
- 2.
- Does stdin work when LAME is compiled to use libsndfile?
- (new version of libsndfile will support this - try this out)
- 3.
- LAME uses a linear downsampling with simple lowpass filter
- on the MDCT/polyphase coefficients. Is this good enough, or
- would a more expensive filter give better results?
- 4.
- make use of subblock_gain (crude algorithm enabled with -Z)
- One method: loop over all possible subblock_gains and
- see which combination gives best distortion? But this puts a lot
- of faith in the short block psycho acoustics
- 5.
- make use of scalefactor_select (crude algorithm enabled with -Y)
- 6.
- 10Hz high-pass filter. Probably wont help much.
