HQPlayer是吟唱昆曲的温婉女子，FOOBAR+FGGB则是朗朗读书的奋发书生。

官网已说明免费的试用版设有 90S 的限制，只有版本比较旧的 foo-RT 学习版才没有那种限制：

In trial mode, PGGB playback stops after 90 seconds if the number of taps is set to greater than 2M or if EQ is enabled.

其实小弟也是仿效 touchzen 大佬那样自制一些学习版，首先下载这个免费的软件：

https://mh-nexus.de/downloads/HxDchs.zip

然后用键盘按 [Ctrl] + [k] 就可以比较原版的和学习版的 foo_pggb_rt.dll／PGGB-RT.dll 这两组文件之间的差别，因此测试版有没有 90S 的限制也变得无关痛痒。

HQPlayer Desktop 和 HQPlayer Embedded 的做法也是差不多，只是文件方面就改为 HQPlayer4Desktop.exe 或者 hqplayerd 罢了，早前发现了学习版 hqplayerd 跟原版 hqplayerd 两者的 MD5 值是一样的，因此就用 HxD 比较一下版本旧一点的 HQPlayer Embedded 学习版，洞悉原版和学习版 hqplayerd 两者之间的分别之后依样画葫芦就行了。

原来还有这种双剑合璧的方法，但是支持 2822K 的 PGGB Offline 版本并无学习版。

暂时 HQPlayer Pro 还是能够成功学习最新的 4.20.0 版本，因此它可以把 2822K 的文件（15 首歌就超过 150G）转换到相对细小的 DSD 64 格式，省却的硬盘空间实在是非常多：

Ok for experiment sake…I upsampled to 2822kHz @ 64bit. Then convert to DSD 64! The sound is insane. I also notice when using HQP the CPU usage is very low. Presume this has something to do with PGGB upsampled to 2822.

What I do know is it sounds really good. I prefer PGGB v HQP. But using PGGB with HQP sound really, really good. Probably DAC dependant for sure. If you have PGGB convert a track to maximum rate & bit depth & play through HQP.

Use 2822 output rate & 64bit then use HQP. Some combination!

Only issue is 1 album with 15 songs was 157gb! Worth creating few playlists mind you.
