> As you may have noticed, we are working on quality benchmark tests. Today, I
> made some sounds with my keyboard and recorded via line-in. I started to encode
> them with different encoders. Soon I found out a sound that no encoder can
> encode properly. It's a simple sound of a hi-hat. I tried with BladeEnc, Xing,
> GOGO-no-coda ver. 2.26, FhG [all versions], and of course, the latest version of
> LAME. But none sounds like the original. FhG sounds best, though. Other encoders
> add a amplified "hissing sound" to the file. You can see the difference even in
> the *WinAmp eq-visualization* display. It seems that the original frequency
> changes a lot.
>
> The sound is recorded with a high volume. Can this cause the problem? I wonder.
>
> The file is of 2 seconds duration. If anyone is interested testing it, please
> let me know.
>
> By the way, are version 3.67 and 3.70 100% same?

> Thank you.
