TODO: In any order Big list, but a lot of it can be done fairly easily with some old code. Note: most of these issues are quite old, and it's not clear who submitted them in this file and why and/or if some of them are fixed in the meantime. The ChangeLog might give some insight on this though. - DONE: Add frequency cutoff filter - DONE: Add ADTS headers - DONE: Write GUI - DONE: Add TNS - DONE: Add LTP - DONE: Add backward prediction (MPEG2-AAC)???? - DONE: Test (and maybe fix) sample rates other than 44100 Hz - DONE: Test (and maybe fix) multichannel and mono support - DONE: Figure out how to read and write ".mp4" format - DONE: Write documentation for library interface - DONE: Improve command line tool - DONE: VBR quantizer - DONE: Speedup - Done: Clean up psychoacoustics code - Done: Add Window shape switching - Add PNS - Add IS - Add bit reservoir control - Add pulse coding (?) - Rewrite noiseless coding (now taken from old version) (?) - Better grouping support (?) - Fix short block psychoacoustics (?) - Fix LTP (hans-juergen, Oct 17, 2004) - Fix Main (hans-juergen, Oct 17, 2004) - Add resampler and downmixer (hans-juergen, Oct 17, 2004) - Add HE AAC (hans-juergen, Oct 17, 2004) - Fix mysterious crash/freeze with some decoded WAV files on Linux: endianness? TNS? M/S? decoder bug? (hans-juergen, Oct 17, 2004) - Fix default ABR cutoff frequencies at different bitrates (hans-juergen, Oct 17, 2004) - Test TNS(arcen, Apr 8th, 2012)
