Emax

Update: I have checked the Emax 8 bit compression algorithm in EMXP and applied some changes - there was indeed something wrong in the algorithm.

It should be OK now; I did some tests with your test WAV files and also with some factory Emax-II banks which I translated to Emax-I with EMXP and everything sounds "cristal clear" now.

The new compression algorithm is implemented in version 2.06.3 and also in the new beta version 2.07.beta.2 which supports SoundFont2.
(available in files section or http://users.skynet.be/emxp)

I hope it's OK now.

For example, the 909 bass drum sample I converted was quite distorted (the original is normalized at -0.3 dB). On the other hand, when I sampled it manually it sounded really good. Also, converting hi hat samples with EMXP added a lot of low frequencies that are not present in the original. Again, manually sampling them gave better results.

I only have an SE and Plus version (which both support playback at 44100 Hz), so I couldn't test if non-SE versions are also able to playback samples at 44100 Hz.
