Description: i writing an free losless audio coder,
faster on old 486 than
flac or ape decoding on pentium 233 MHz !!!
the program working, and compression ratio is equal to flac / ape ...
On pentium 233 MHz flac decompress time is 26 sec of enya_.wav . ape is more than 45 sec... :)
approx 14 sec coding enya.wav with pkzip, and my routines not have completed.
My hope is 4 sec compression time, if completing,
and decompressing a 16 bit stereo 44100 Hz is real time on 80286 cpu !!!
PLEASE HELP ME !
i am an hungarian programmer, and i cannot wrtite in english perfectly.
i not have time for write code for
incoming 16 bit variable contents !
i want variable bit size putting into 8 bit foam.
the 16 bit variable containing e.g. 7 bit valuable data,
and 8 of this data must be storing into 8 bit datas.

Description: 8-32 kbit/s语音和视频的结构误差不稳定窄带和宽带嵌入式变数率编码-The G.718 encoder can accept wideband sampled signals at 16 kHz, or narrowband signals sampled at either 16 or 8 kHz. Similarly, the decoder output can be 16 kHz wideband, in addition to 16 or 8 kHz narrowband. Input signals sampled at 16 kHz, but with bandwidth limited to narrowband, are detected by the encoder. The output of the G.718 codec is capable of operating with a bandwidth of 50 Hz to 4 kHz at 8 and 12 kbit/s and 50 Hz to 7 kHz from 8 to 32 kbit/s.
