I was trying to record with studio quality, 96000 Hz but noticed the recording timestamp was moving too slowly. Playing it back it played the audio too fast. I tried putting it on DVD quality, 48000 Hz, but had the same problem just not as bad.
I have this problem on both my HP EliteBook 8440p running Windows 10 and my HP Envy 750-427c. I don’t know what to do.
I tried changing the microphone’s properties and Audacity’s quality preferences.
How bad is it? More that twice as fast at 96kHz?
What are you recording? (The microphone built-into your laptop? From an external microphone? Streaming audio? Etc.?)
It’s bad to the point it sounds like a chipmunk, I don’t know the speed specifically.
I’m recording from an external microphone, a Rode NT2A.
It could be a sound card driver problem, or a Windows sound system setting, but do you really need to record at higher than 44100?
I don’t know if I need to. I’m just having a problem where on both computers my viola sounds scratchy while on a friend’s computer using the same speakers and same microphone it sounds cleaner and smoother.
But I just found out this morning that he was using the lowest settings so I don’t know. Might be the fact that his sound card is higher but again, dunno. Any suggestions?

I don’t need to record higher than 44100hz I was just curious if that was the problem I was facing.
I’ve been trying to record my viola but it comes out as scratchy, I recorded on a friend’s computer using the same microphone and speakers and it comes out sounding smooth and clean.
I found out this morning his recording settings were set to the lowest though, so I’m not sure what it could be besides the sound card.
Rode NT2A.
You can’t hook an NT2A directly to a computer. There should be a piece in the middle. The piece in the middle determines the sample rates, speeds, bit depth, etc, etc, etc.
What is it? I use a Behringer UM2.
Scratchy sound can be caused by simply using the microphone system wrong. See the two lights on the front of my UM2? SIG and CLIP? The SIG lights comes on when I use the microphone and system in its normal volume range. The CLIP light comes on when the sound is too high. Some interfaces use one light that changes colors.
What do you have?

Not this time. That catches everybody. I think the record is three identical posts from someone who thought their original post didn’t “stick.”
I’m going to look up your interface. I’ll put heavy money on you have a wrong adjustment somewhere. There are conditions where the system refuses to run at higher quality settings. 48000 sample rate is the standard for video recording, so not having it run at that rate is most concerning. I used to shoot voice tracks for the video editors and deliver in 48000 because I knew that’s the speed their videos used.

That sounds like a driver problem. Driver problems are rare, but part of the driver’s job is to communicate the sample rate between the hardware, software, and operating system.
If you are actually recording at 44.1kHz but it’s getting “tagged” as 96kHz it will play more than twice as fast and it will sound like chipmunks. 44.1/96 = 0.459 so a 1 minute recording would play back in 27.5 seconds.
But since you say it sounds scratchy, it could also be [u]dropouts[/u] which are usually related to multitasking (and the computer is always multitasking even when you’re only running one application). Dropouts cause “glitches” in the recording and the missing data sometimes makes playback faster (if you don’t get silent gaps filling-up the space). Dropouts are more likely at higher sample rates.
Temporarily stick to 44100.
Your interface has an actual sound level meter (flashing lights).
Play as loud as you can and adjust GAIN INPUT-1 until you only get green lights. Maybe an occasional yellow.
You should never, ever get that red CLIP light. That means the sound got so loud that it didn’t fit in the interface and has damage.
I bet the fuzz goes away when you do that.
I don’t know what that big knob does and I have to leave for a while.
