<p><b>New page</b></p><div>=For speech=<br />
<br />
To do: upload HQ mp3 or wav samples.<br />
<br />
The sample taken as example is [[Nam1975]]'s soldier voice (young man): "Now we're called heroes, but the hell continues".<br />
<br />
==Original sample rate: 18500Hz==<br />
Everyting fits in f/2 = 9250Hz. The highest components (the "S"es from "heroeS" and "continueS") are around 5500Hz.<br />
<br />
[[File:nam18500.png|512px]]<br />
<br />
==16384Hz==<br />
Quality difference acceptable. Everything still fits in f/2 = 8192Hz. Size gain: 11%.<br />
<br />
[[File:nam16384.png|512px]]<br />
<br />
==12000Hz==<br />
Quality difference noticable in "S"es. f/2 = 6000Hz starts getting close to the highest components. Size gain: 35%.<br />
<br />
[[File:nam12000.png|512px]]<br />
<br />
==8192Hz==<br />
Quality degradation very noticable. "S"es chopped off because f/2 = 4096Hz, < 5500Hz. Size gain: 56%.<br />
<br />
[[File:nam8192.png|512px]]<br />
<br />
==4096Hz==<br />
Starts affecting voiced sounds harmonics, would be barely intelligible on cab speakers. Size gain: 78%.<br />
