Windows 7 recording/playback problem
« on: September 28, 2010, 03:39:19 »
When I use my Windows 7 to record sounds with any program (or maybe just with the programs that I use) there is a high-pitched ringing sound that accompanies low-frequency sounds. This is noticeable in bass kick sounds and bass if there is not much else happening in the song. I also notice this when I create a low-frequency sine wave (55 Hz, for example) with Audacity and play it using Audacity. I have 2 Windows 7s, and both of them have this problem. Can anyone confirm this? Is there a way to fix this problem?
I have no sig—wait, what this?

If you record an empty wave, do you hear it to?

Do you hear it if you playback a silent track, or is it part of the recording?

What soundcard do you have? Are those 2 windows 7 installs on 2 different pc's with different hardware?

I'm looking into where the noise gets part of your sound. Is it during playback or during recording?

I run Windows 7 too and have no issues.

At least it certainly isn't a problem with Windows 7. It could mean that your soundcard / onboard sound sucks. :P I was thinking of aliasing noise first, but that would be strange if you would still encounter it also in f.e. OpenMPT with Polyphase interpolation enabled. A recording of this noise would certainly help to identify the cause.

I forgot to mention, this problem does not occur with MPT.

If I record an empty wave, I will not hear the sound. It's most noticeable with low-frequency sounds.

I will not hear it if I play back a silent track. It only occurs when there is sound.

I use Realtek High Definition Audio.

I noticed that if I export my sine wave and play it with windows media player, I will not hear the ringing sound. However, if I record sounds and save them, the ringing sound will still be present.

Well... no comment :P

I think you're dealing with aliasing noise there. Are you, by any chance, working with 8-bit samples? It sounds like the application you're working in has no interpolation enabled.

Some hardware, like Audigy 2, is locked on a certain samplerate, 48kHz in
case of Audigy, all the other formats have to be resampled in this case.

I'd like to hear an example, it's hard to describe sounds with words.

That's not something you'd hear that clearly tho.

I wouldn't be too sure about that, this sound chip is ubiquitous, which means that it's rather cheap.
