Audio Slight Ringing Distortion from Recording Video with System Audio

I'm trying to use camtasia to record some videos with audio but am getting a lot of ringing distortion.

https://soundcloud.com/touchtheuniver...

I alternate between a normal wave of the audio in question that is streamed from the daw and sounds good, to the audio of a screen record with camtasia, by a bar each. It's pretty obvious the difference.

I've browsed the camtasia forums and it seems it only plays well with audio at 22500 and 44100 sample rates, whereas my soundcard, coxenant smartaudio HD, is set to 48000 sample rate and there is no 44100 option!?

What are my options. I have asio but I cannot record audio using a screen recorder with it. Does my audio card simply not support a 44100 sample rate and it is tied to the hardware, or can I install a different driver, something to set my system to play nicely with camtasia?

Specs

My soundcard is running at 24 bit at 48000khz sample rate, stereo
Windows 10 64 bit

Are you sure the problem is only with Camtasia? I use Camtasia with an Edirol FA-66 which is set to 192000Hz by default. It is an external unit connected through firewire.

I have no problem recording sound, other than a low buzz with the microphone which is system-wide due to ground connection.

Next to a possible driver problem, in my experience cards may sometimes get interference from other devices, especially when they get power from USB next to other USB devices as simple as a mouse.

BTW, your specs should probably be 48000Hz or 48KHz. ;)

You never said whether you were using v8 or v9...  assuming you know MP3 is an issue in 9... I always had good audio results in v8 and earlier... audio in v9 can be problematic unless you make sure you are M4V or WAVE

Hi. Thanks. I'm using Camtasia 9 with wave files. Actually, I'm a music producer, so the sounds are generated live from a vsti, it technically isn't even a wave file, it is sound directly generated in its purest form and recording. I think it is still conisidered a wave file though since a wave in uncompressed pure audio.

Also, I'm using a focusrite external sound card, well I have access to it, I will see if I get the same distortion when it is plugged in. The above was using the default windows sound card that came with dell.

Tim I did not hear any ringing in the audio from the link in the above post you provided. It sounded good on my Laptop and Desktop which I checked with headphones on.

As far as ASIO it is not used in Windows as Windows uses more of an WMD with the Pro Audio Interfaces. However there are some things you can use to make the ASIO work like VoiceMeter which the link fot this is below if you want to check it out and see if it may or may not work for you.

As far as VSTI it is a Plugin more than a sound format like .WAV files. It is used by Cubase and other Audio Recording Apps.

I would not advise using the built in soundcards on Laptops as they bring into to much noise internally and are not as reliable or have good quality for the sound recording in my opinion. A Desktop computer with built in soundcards may give better results but I have always used USB Soundcards or USB AUdio Interfaces for my recordings. Not sure which Audio Interface you have and use but these are just my suggestions and opinions so take them for what they are worth and maybe they will help a little.

Thanks for posting and have a great day/night.

Thanks. Nearly every audio professional I know uses ASIO due its insanely low buffer settings. No one really uses stock windows sound card drivers, in fact, even audio drivers that cost 1000 dollars still do no offer the same benefits as the free ASIO driver. Just a heads up ;)

The highest audio quality in a format is wave files, its is roughly 2000kbs. When streaming through a DAW pure audio is generated at whatever settings are aligned insided the daw through sample rate, bit depth. They would streamed live at a quality identical to a wav format.

Also, there is very much a lot of distortion in the file, it sounds a bit crusher is running througout the parts. The same sound when audio is upsampled or down sampled, which is what I think is happening here. I'm capturing at 48000hz and it is being down sampled to 441000 via camtasia, i think..

OK, so why is it when I listen to the original source audio, it sounds fine, but when I record a screen capture with audio, the audio has a ringing distortion on playback.
This is a Camtasia issue, not a sound card issue.

Can you provide more information on your recording setup as far as what equipment or mic(s) you are using and what your settings are when you record and produce etc. I cannot say that it would be or not be a Camtasia issue but there have been problems in the past and more information would help to give a better suggestion to try and help. Thanks.
