The 22kHz file has been encoded in a lossy way (like MP3 at 64kbit/s or even lower). Especially for old MP3 encoders, it's very common to put a low-pass filter in fron of enoding to limit the amount of frequencies that might …
What Does The Hz-KHz Range For Speakers And …

It’s generally labeled as the “frequency response” and expressed in hertz, with kilohertz being a thousand hertz. So the typical frequency response for headphones, twenty hertz to twenty thousand hertz, is quite full indeed. More expensive models can go even higher and lower; the $700 Sony set in the image above has a range of 4Hz-100KHz.

The Test File. 22 kHz → 8 kHz Sweep. + Voice Over. A -9 dbFS sweeping sine tone, from 22 kHz (supposedly inaudible) down to 8 kHz (if you can't hear this one, consider checking your hearing). On the top of the test tone, a voiceover tells you which frequency is currently playing. For this one, keep your computer's audio levels down!

Re: Audio files 22KHz 16 Bit for the new Sound Module. We've kept the new sound module compatible with the original Emartee module as far as the interface is concerned, hence the file names are as they are. I could add an option to allow you to choose your "Welcome" message number.
Imported MP4 with 22kHz audio stutters - VideoPad - NCH ...
https://nch.invisionzone.com/topic/38670-imported-mp4-with-22khz-audio-stutters/
Now, some of the MP4 video files I import for editing render fine, while others the audio stutters and sounds like it's double speed. The only difference I can spot is that the audio on the problem files is 22kHz sampling rate AAC LC. 44.1kHz files seem to render fine. I tried installing the latest 64 bit version of VP but the problem remains.

The audio files (*.wav) are in MS-WAVE format, downsampled to 22kHz mono from the original CD tracks. The transcript files (*.phn) are text files where each line has the format <start-sample> <end-sample> <description> ..where the samples are at 22kHz, so you convert those numbers to time in seconds by dividing them by 22050.
