labview正弦扫频信号发生器
应用背景用于产生一个正弦扫频信号,我是用来测量声音在粮食中的衰减程度,扫频信号它与噪声的相关程度比较小,接收到的波形不易失真,所以设计了这个声音发射器。关键技术产生一个正弦扫频信号,并且扫频信号的幅值,发声时间以及起始频率和终止频率可以在前面板中进行设置,通过适当的调整便可以得到一个你所需要的声音发声器

我写一个免费的图象音频编码器,
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.
(code need 24 .. 2 bit incoming packing into 8 bit data.)-i writing an free losless audio coder,
faster on old 486 than

pwm语音数据幅值缩放
应用背景在利用codec进行语音数据输入和发送时,可以利用该文件提供的函数对输入和输出的pwm语音数据的音量进行缩放。关键技术对PWM语音数据进行幅值上的缩放,从而达到对codec输入或者输出的pwm语音数据进行缩放的目的。控制的参数是对语音数据进行控制的系数,0值语音数据音量就为0了。
